Apparently now I have to re-configure my settings after every update of the applet; is this really necessary?

claudiux-6 days ago

The measured values will be more accurate in version 2.2.1.

CtrlAltDel1-6 days ago

Claudiux, thanks for the prompt action on the issue. Unfortunately, for me, now it seems as if Multi-Core System Monitor 2.2.1 itself is causing slightly elevated CPU usage. With the program running, Gnome System Monitor is consistently showing CPU usage values in the 8-15% range on most of the cores. In the previous version, Multi-Core was showing 50-60 percentage ranges on all the cores but Gnome System Monitor was showing 0-3% on all cores when computer was idle, as is normal. Put more simply, while using Multi-Core 2.2.1, actual accurate readings of CPU values on Gnome System Monitor never drop down to the 0% - 3% range, they are slightly elevated. With Multi-Core running with computer at idle and no programs open or running: https://i.imgur.com/EP8B7xy.png Without Multi-Core running with same conditions: https://i.imgur.com/sC204kA.jpeg

Lee C Williams-6 days ago

I got curious about this and can confirm that the applet is causing additional CPU usage; after removing it the usage dropped similarly to CtrlAltDel1's.

claudiux-6 days ago

(about CPUs).

Lee C Williams-1 week ago

Hey Claudiux! Great fix; usage is back to normal! :) Only issue still is when using: Colour by activity level + NOT use automatic colours; it only uses the 20-40 colour, randomly changing to white sometimes on random cores. Minor issue: CPU graph doesn't use the full space even with labels disabled (also if labels could be enabled per graph instead of all on/off that'd be great.) I'm also not entirely sure about having a table of colours instead of setting them per readout. I had configured the network and disk IO colours to be more distinguished for all drives and now I can't tell which is what without having to go through them all again in a clunky and limited fashion; 2 Network types, up and down is 4 colours used. 6 disks read and write is 12 colours used- yet there's only space for 15. While I realise I may be an outlier in this regard it's still a bit of an iffy change.

claudiux-1 week ago

The calculation of CPU usage is now correct with v2.2.0!

CtrlAltDel1-1 week ago

As mentioned by several others, extremely erratic and incorrect CPU Usage date showing false high readouts. Have reinstalled, a couple of times, rather than just updating to attempt to rectify issue thinking it was a problem on my end. Thanks to Claudiux for a great and beloved applet and will be checking back periodically to see when I can start using it again. :-)

CPU Usage Data

Lee C Williams-1 week ago

Latest update, CPU non-automatic colours doesn't work, it just sets them all to white, I also have to echo Piotr and YashaNoos, the core percentage is way off and looks to be almost 100% constantly when actual core usage is closer to 4%. Also now missing the ability to turn the labels off.

Piotr Kozaczuk-1 week ago

All cores 33% on idle (AMD zen3), custom colors for CPU usage bars not working Using Mint Cinnamon 6.4.8, v2.1.0

YashaNoos-1 week ago

Since the update the cpu monitor behave strangely and display higher cpu usage than reality, like 50% + on half the cores on an idling system while the task manager show reasonable usage. Using v2.1.0 Cinnamon 6.4.8

Steffen Dünner-1 week ago

Wow, 2.0.0 looks like a big update. One thing that I already direly miss is clicking the graphs does no longer open a task manager. Can this functionality be added back again please?

claudiux-1 week ago

v2.1.0 is for you.

Filip Leander-2 months ago

Is it possible to show just percentage (such as RAM: 17%) instead of the graphs? I have been able to remove labels and hide graphs, but not this.

claudiux-8 months ago

v1.9.9 is here. It provides a better reading of swap usage and so fixes issue #5177.

claudiux-8 months ago

v19.8 is here. Now this applet works even even then you plug-in or plug-out an ethernet device on a USB-C port. In addition, by right-clicking on this applet, you can choose to drop the memory cache (or at least reduce its size) to obtain truly free memory. Enjoy!

claudiux-8 months ago

You'll only see the option to delete the memory cache if you're a sudoer (i.e. if you can use 'sudo').

Wolfen113-1 year ago

I already asked this question a year ago. No one answered, but maybe this time there will be an answer. Does anyone know how to replace the launch of gnome-system-monitor with system-monitoring-center? I removed gnome-system-monitor and replaced it with another one. But now, when I click on Multi-Core System Monitor with the mouse, nothing starts. Arch Linux, cinnamon.

claudiux-1 year ago

Are you sure? *** Announcement (31.10.2023): End of support for System Monitoring Center v2.x.x. The project is ended. System Monitoring Center 12.2020-10.2023. *** Source: https://github.com/hakandundar34coding/system-monitoring-center

Wolfen113-1 year ago

Sorry, I'm writing this through Deelp translator. Even though you say that system-monitoring-center is outdated. Nevertheless, I don't want to switch to gnome and I put a monitor from aur. I had to seek help from gpt4o chat to solve my problem and he found it. What would your multicore-sys-monitor see my system monitor. I had to manually in the file ~/.local/share/cinnamon/applets/multicore-sys-monitor@ccadeptic23/х.х/applet.js Fragment of the configuration file running the gnome system monitor, replace with: _runSysMon: function() { let systemMonitoringCenter = appSystem.lookup_app('system-monitoring-center.desktop'); if (systemMonitoringCenter) { systemMonitoringCenter.activate(); } }, And then in /usr/share/applications/ create a new shortcut system-monitoring-center.desktop/ Since my system is in Russian language as well as all shortcuts in it. Therefore multicore-sys-monitor did not see the required system monitor, and did not run. This solved the problem temporarily. But after every update of multicore-sys-monitor, configuration files are reset to default. If multicore-sys-monitor would have a function to manually select which system monitor it will run, through a graphical interface, regardless of the name and language of the system. This would be a solution for many people. About which people have already written below, complaining that even the gnome system monitor is lost.

claudiux-1 year ago

That works well on my system (Mint 22 Cinnamon 6.2.7): _runSysMon: function() { let systemMonitoringCenter = appSystem.lookup_flatpak_app_id ('io.github.hakandundar34coding.system-monitoring-center'); if (systemMonitoringCenter) { systemMonitoringCenter.activate(); return } let gnomeSystemMonitor = appSystem.lookup_app('gnome-system-monitor.desktop'); if (gnomeSystemMonitor) { gnomeSystemMonitor.activate(); } },

claudiux-1 year ago

I'll test it on Arch...

claudiux-1 year ago

This one works well on arch: ``` _runSysMon: function() { let systemMonitoringCenter = appSystem.lookup_flatpak_app_id('io.github.hakandundar34coding.system-monitoring-center'); if (systemMonitoringCenter) { systemMonitoringCenter.activate(); return } systemMonitoringCenter = appSystem.lookup_app('io.github.hakandundar34coding.system-monitoring-center.desktop'); if (systemMonitoringCenter) { systemMonitoringCenter.activate(); return } let gnomeSystemMonitor = appSystem.lookup_app('gnome-system-monitor.desktop'); if (gnomeSystemMonitor) { gnomeSystemMonitor.activate(); } }, ```

claudiux-1 year ago

v1.9.7 is for you.

claudiux-1 year ago

1.9.6, sorry.

Wolfen113-1 year ago

I installed the 1.9.6 update. Everything works fine now. I don't even have to manually create a desktop shortcut in /usr/share/applications anymore. For several years I thought this problem was impossible to fix, But you fixed it and made my day better. Thank you!

FireStarW-1 year ago

I updated to Ubuntu 24.04 from 23.10 recently and it seems this applet no longer opens the gnome-system-monitor upon clicking it.

FireStarW-1 year ago

looking at the applet, it looks like ubuntu may have renamed the gnome-system-monitor *.desktop to "org.gnome.SystemMonitor.desktop", away from "gnome-system-monitor.desktop", which the applet expects

claudiux-1 year ago

Thank you. I'll take that into account.

claudiux-1 year ago

v1.9.7 is for you.

claudiux-1 year ago

1.9.6, sorry.

Foxtail-me-1 year ago

On Linux Mint 21.3, at some point the RAM and DISK graphs disappear, leaving only one CPU. If I close any program, the graphs return. Most often it works when closing Firefox. Updating the graphs does not help, even deleting and adding the applet has no effect.

Foxtail-1 year ago

It looks like I understand the reason, RAM and DISK disappear if applications with RAM limitation are running: systemd-run --scope -p MemoryMax=2G --user firefox

europe1453-7 months ago

The same behavior on fresh install of Mint 22. "Refresh graphs" shows MEM NET DISK for a second but w/o graphs and then only CPU remains back again. Did you find a workaround for this bug, it's not clear from your comment? I'm going to temporarily leave only CPU graph until this will be fixed or don't use it at all.

claudiux-1 year ago

Version 1.9.5 allows you to choose, in the context menu (right-click), whether the applet should be displayed with or without graphics. The tooltip with values is still present.

heavenlyhexidecimal-1 year ago

Perfect. The option for just the tooltip is really useful. Just like in "sensors monitor" app.

JackDawson2025-1 year ago

Hi! sorry to bother you so much! could you please add the latest changelog in this web page and leave it like in the Sensors Monitor web page if it is not much trouble and effort? thank you!

jjadup-1 year ago

My favourite Cinnamon applet. Highly customisable and keeps me informed of my system's status.

Maknesium-1 year ago

Hi, I upgraded from Linux Mint 20 to 21 and found out that the applet doesn't work in vertical panels anymore. It worked in LM 20. Is there any chance the vertical panel support will be added in the future? It's been requested in the past (see further down).

claudiux-1 year ago

Hi, I've never seen this applet work in a vertical panel. Are you sure you're not confusing it with another applet?

Leokuma-1 year ago

Fantastic extension. I just have one question: is it possible to have 2 different color configurations, one for dark theme and another for light theme, so that when I switch Mint's color scheme, the applet also switches its colors automatically?

claudiux-1 year ago

Thank you for your kind comment. Good feature request! I'll take it into account for a future version.

plumber-craic-1 year ago

I also like this idea. As I move from bright to dark environments I switch my OS theme to reduce eye strain. Thanks for a great applet!

Tariq Sajid-2 years ago

@claudiux were you able to find solution for disk i/o. and another question if user has two drives how to select drive to monitor

claudiux-1 year ago

Sorry, I'm very busy at the moment and I need to buy a new PC with an NVMe disk; my current PC doesn't accept this type of disk.

Tariq Sajid-2 years ago

disk i/o not working if user has nvme drive

claudiux-2 years ago

I'm working on that now.

angelotux-2 years ago

thanks claudiux now only a nice applet for the cpu governor is missing

claudiux-2 years ago

I'm thinking on it. Is cpupower-gui running well for you? (apt install cpupower-gui)

angelotux-2 years ago

it would be interesting to have the gui in the panel .cpu power has a window that must necessarily remain open we would like the applet type indicator-cpufreq which does not work well it is an abandoned project, or CPU Frequency Applet which does not work crashes and does not change governor

claudiux-2 years ago

v1.9.4: I added the 'Refresh graphs' option in the contextual menu (right click on this applet). Enjoy it!

claudiux-2 years ago

Also, the maximal refresh rate is now: 3 seconds (3000 ms) as requested by @jondo in https://github.com/linuxmint/cinnamon-spices-applets/issues/3342

Andrei Miculita-2 years ago

I only have 2 graphs enabled, CPU and Memory. Is it intended that when refreshing, 4 graphs are shown?

Andrei Miculita-2 years ago

Note that they are only shown briefly, the applets then reverts to 2 graphs. But It changes the layout of the panel.

claudiux-2 years ago

I see. I'll try to solve this issue.

angelotux-2 years ago

excellent applet however on linux mint cpu governor cpu applet like this is missing https://extensions.gnome.org/extension/945/cpu-power-manager/ is it possible to have this kind of app?

claudiux-2 years ago

Thank you! Interesting. I don't know if this CPU governor can fit in this applet or if a new applet is needed for it. I'll think about it.

claudiux-2 years ago

This applet already exists: https://cinnamon-spices.linuxmint.com/applets/view/70

angelotux-2 years ago

ryzen 5700g the cpu always remains in performance it does not change in saving or on demand

angelotux-2 years ago

doesn't work latest version mint cpu check is not working

claudiux-2 years ago

Hi dear users, I am the new maintainer of the multicore-sys-monitor@ccadeptic23 applet. I intend to clean up his code and thus remove the versions for Cinnamon 3.0 and 3.2 (Linux Mint 18 and 18.1, expired since April 2021). Are these versions still used by some of you? Thank you for telling me. Claudiux

claudiux-2 years ago

Version 1.9.2 is here. Now, CPU activity bars can be colored by activity level (five sets of levels: 0-20%, 20-40%, and so on in 20% increments). You can also choose to color these bars automatically, by progressive color from blue to red (blue: close to 0%, red: close to 100%). Enjoy!

claudiux-2 years ago

Version 1.9.0 is here. Now this applet is compatible with fresh install of Linux Mint 21.1.

Alexey Seliverstov-2 years ago

I think I managed to fix the issue for a fresh install: https://github.com/linuxmint/cinnamon-spices-applets/pull/4665 As a workaround while this is not merged and deployed, run the following: mkdir -p ~/.cinnamon/configs

claudiux-2 years ago

This issue is solved since v1.9.0. Please update this applet.

Alexandru Dragos-2 years ago

Great! It works. Thanks!

csabaz-2 years ago

Thanks! It works!

llueveYescampa-2 years ago

Thanks! that work for me.... first : mkdir -p ~/.cinnamon/configs Then : reinstall the Multi-Core System Monitor

Vlad Rusu-2 years ago

Not working on fresh install Linux Mint 21.1 ... please fix this, I can't live without this addon. :(

Wolfen113-2 years ago

Clicking on the applet with the mouse opens gnome-system-monitor. It's fast and convenient, but what if I changed it to another monitor, for example, mate-system-monitor. Is there a way to make it launch when clicked?

llueveYescampa-2 years ago

not working for me either on a fresh install of mint 21.1

janos-r-2 years ago

I just went from mint 20.3 to 21.1 and this app seams broken. I loved the cpu bars, I dont know if any other app has that. Can please somebody confirm if this is really broken on mint21? Thank you

Graeme-2 years ago

Confirm that it does not work for me either on a fresh install of mint 21.1. Worked fine on 21, or if you upgraded from 21 to 21.1.

csabaz-2 years ago

I confirm, it doesn't work for me either - Mint 21.1 / Cinnamon 5.6.5

Kim W.-3 years ago

Good, but System Monitor by orcuscz offers more and it's nicer. Thanks anyway.

Cinnamon 5.0.7 with applet 1.8.91, desktop freezing

dhdurgee-3 years ago

Running Cinnamon 5.0.5 here with your applet 1.8.91 (2021-04-04 13:07:04) I find you are allocating excessive memory overnight while the cinnamon screen saver is running. I have my memory-limit set at 320MB and in less than three hours of screen saver the limit will be reached with your applet enabled. I disabled your applet last night at 21:33 and even now Cinnamon is only using 115Mb here. If you need additional information to correct this problem please let me know. If you have a debug version or test you would like me to run please contact me.

daytooner-4 years ago

iznobe-4 years ago

Hi and thanks for this cool applet ! i got a cpu with 32 core ... son i can't see all the visible part of this applet . there is a way to display an average usage of all core CPU and choose this instead of all single 32 core please ?

msegmx-4 years ago

Thanks for this great applet! Came here to make a feature request for "CPU temperature" as well.

Andrei Miculita-4 years ago

Would be nice if it also showed CPU temperature, atm it's a bit inconvenient to install a whole other applet just for that.

Robert Pollak-4 years ago

Thank you for this applet, and happy holidays! May I wish for a maximal refresh rate of 3 seconds? (see https://github.com/linuxmint/cinnamon-spices-applets/issues/3342)

Aryeh Beitz-4 years ago

Prsman-4 years ago

I just installed this and it does not work. I get the files in ~/.local/share/cinnamon/applets/muliticore..., but nothing in ~./cinnamon/configs/multi... In system setup, I get the info icon, nothing else. Running Mint 19.3 Cinnamon. I have the gir1.2-gtop-2.0 package installed. Any Idea?

chennecke-5 years ago

I upgraded to Linux Mint 20 using kernel 5.4.0-40 and after a long time of working without a hitch, the system now shows frequent hard freezes a few minutes after booting where nothing helps except pressing the reset button. I removed the applet and the system has been stable for some hours now. Any ideas? I really like this applet.

allanfr-5 years ago

This latest version 1.8.91 (2020-04-19 21:43:39) has fixed the 'freezing' issue I experienced (reported by scomoletti). The workaround was to logout-user then log back in. Multi-Core System Monitor now functions every time the PC boots, which is a great relief as the applet is VERY useful for keeping an eye on system health. The issue only affected my desktop PC, and 2 laptops also with Multi-Core System Monitor, never exhibited the freezing problem.

janos-r-5 years ago

Please, Im just setting up a new system on an nvme that I had to set to sata AHCI in bios, linux wouldn't recognize it. But now the disk IO doesn't show any graphs... It is enabled and scaling and everything is switched on in the disk settings of this app, but nothing visible. Does anyone know about this behavior? Is it because of the NVMe? Or AHCI? Or because it is one of two disks in the pc? At my work, I have also two but it worked just fine. Thank you for any response.

dolour-5 years ago

Same issue here, doesent show any disc usage for the partitions on my NVMe drive. The mechanical ones work fine tho.

saaj-4 years ago

Here's the workaround I put together for my `/sys/block/nvme0n1/stat` https://gist.github.com/saaj/82080ff888e740f5561dc8362b6ee6a9.

gilcu3-5 years ago

The same is happening here. Disk usage doesn't show any data, does anyone know where to find logs for this applets?

Tomáš Kopal-5 years ago

Same here. I think it is a libgtop issue (in my case, I am on LVM). See discussion in different applet with the same problem: https://github.com/linuxmint/cinnamon-spices-applets/issues/2801 Libgtop tickets are quite old, so I don't think it will get fixed any time soon. Any possibility to have disk I/O implemented differently in this otherwise great applet?

Tomáš Kopal-5 years ago

What about using udisks? For inspiration, check out this applet/desklet: https://github.com/mariusvam/Drives-Manager Seems to be doing what is needed...

oneEyedCharlie-5 years ago

This is the best applet for *any* OS. Thank you developers for continuing to maintain it.

scomoletti-5 years ago

v1.8.91 Appears to have trouble on Mint 19.3 with Cinnamon 4.4.5. CPU stops updating after a few minutes and I don't think I've noticed MEM update after initial start either. Network and Disk both stop updating and preferences is inaccessible shortly after CPU stops updating. Applet never crashes completely and does launch the system monitor correctly when clicked. I did upgrade from 19.2, and followed the steps to remove configs and cached files.

vtvbreech-5 years ago

I am having this exact issue on 19.3 as well

claudiux-5 years ago

Do you also use one of these applets? turbonote@iksws.com.b vnstat@linuxmint.com netusagemonitor@pdcurtis

claudiux-5 years ago

The latest version of this applet fixes this issue.

vtvbreech-5 years ago

I did not have any of the other listed applets installed but the latest update does indeed seem to be working again. Thanks for looking into things though, appreciated. Thank you jaszhix for quickly implementing a fix.

claudiux-5 years ago

Glad to know this applet does the job again. But it was I, not jaszhix, who fixed the issue. ;-)

vtvbreech-5 years ago

Oh, my sincere apologies for the mistake claudiux. Thank you very much for fixing the issue for us :)

allanfr-5 years ago

I'm having the same issue as posted by scomoletti, even with the latest 1.8.91 (2019-12-29 07:19:23) version. The only way to get Multi-Core System Monitor to work correctly is to Log-out of Mint 19.3 then Log-in again. The app then works fine until a full PC re-boot i.e. starting the PC from scratch causes the applet to 'freeze' after approx 10s. Anything else I could try as this app is really, really useful?

allanfr-5 years ago

CORRECTION: After deleting the applet and re-adding and setting preferences, all is well. Previously I had 'updated' using the Applets utility. It seems a full delete + add is required.

zehm-5 years ago

Thanks so much for this, I couldn't imagine Linux Mint without this thing :)

claudiux-5 years ago

Now works well in Cinnamon 4.2, with a new display of its tooltip, more readable.

Patrick Thompson-6 years ago

There appears to be a patch that has not been merged yet. I tested the changes locally and they work. modify ~/.local/share/cinnamon/applets/multicore-sys-monitor@ccadeptic23/meta.json to include version 4.2 as such: https://github.com/linuxmint/cinnamon-spices-applets/pull/2472/commits/474da9740370dea8f53abf69780207ba7b798bb2

Would it be possible to adapt the layout for vertical panels?

LaGallinaTuruleta-6 years ago

No JS module 'simple-system-monitor@ariel' found in search path Could not load desklet simple-system-monitor@ariel Any solution for this?

Josinaldo A.Barbosa-6 years ago

very good applets, I have disk m.2 in the system "/" and does not display the information, my external hd works :/

dhdurgee-6 years ago

Just had to restart cinnamon here and after the restart hovering the mouse cursor over the monitor no longer displays the pop-up details. I can still click on it to open the system monitor or right click to pop-up the menu, but hovering isn't working. This is in CobiWindowList and I find that hover works as expected on pinned apps with open windows and other widgets. Let me know if you need more information.

Miko-6 years ago

Very well maintained! Thank you for this.

bradenfontaine-6 years ago

Simple, gorgeous, effective.

could you make a section with the cpu temperature ? Would be awesome !

Awesome !

dhdurgee-7 years ago

I separate my data from my boot partition, so only the boot(root) partition displays on my system. I assume there is a way to add my data partition, but I see no way to add it in the preferences. I assume that it can be added by editing your prefs.json, but I have no documentation on how to do so. Would the additional disk display in the same area as the root? If so, I would need to change colors to distinguish them from one another. I am in the process of recovering from a hard drive failure. It would have been great if had been an indicator of some sort in my cinnamon panel telling me how healthy my hard drive is. I understand that such data is available from the drive via S.M.A.R.T, but from what I have seen you can drown in details there and it takes understanding of the data to determine the state of the drive. I would like to see a simple colored dot in the disk display colored green if the drive has no problems at all, yellow if there are signs of problems developing and red if the data on the disk is in danger of loss. Any variant on this would be acceptable and would have warned me to buy an new drive and clone the current one prior to failure. I am unaware of any other applet with such a feature and yours appears to be a good fit, so please consider this added function. Dave

Hi Jason, I can confirm issue with height settings. It is no respected at all on my Arch linux box. When I enable bluetooth I also have issues with glibtop spammig my .xsession-errors file with ... glibtop(c=15403): [WARNING] Failed to open "/sys/class/net/80:96:B1:8F:D6:CA/statistics/rx_bytes": Adresář nebo soubor neexistuje glibtop(c=15403): [WARNING] Failed to open "/sys/class/net/80:96:B1:8F:D6:CA/statistics/tx_bytes": Adresář nebo soubor neexistuje ... thanks

Hi Jason, since the last update (I updated recently, don't really it often) current version does not respect height setting. Height of applet never changes, whatever I set it to. I have the same behavior on Mint 18.2 and Arch Linux. Since I set my panel to be a bit smaller that default, this applet is now too big. Thanks.

Jason, I have been using the applet for many years and I appreciate your active involvement on this great applet. The applet is still working perfectly but I have recently noticed it is gradually filling up .xsession-errors on my machine until it reaches the file size limit. dmesg looks clean. I am using Mint 18.2/Cinnamon 3.4.6 and I have done a remove and reinstall of the applet clearing folders as suggested. Following repeated 2400 times. glibtop(c=4329): [WARNING] Failed to open "/sys/class/net/08:3D:88:DA:A7:A5/statistics/tx_errors": No such file or directory glibtop(c=4329): [WARNING] Failed to open "/sys/class/net/08:3D:88:DA:A7:A5/statistics/collisions": No such file or directory glibtop(c=4329): [WARNING] Failed to open "/sys/class/net/08:3D:88:DA:A7:A5/statistics/rx_packets": No such file or directory glibtop(c=4329): [WARNING] Failed to open "/sys/class/net/08:3D:88:DA:A7:A5/statistics/tx_packets": No such file or directory glib --- MDM: .xsession-errors output limit reached.

I've seen this too, I did change the network device handling, but not the API calls. I'll experiment a little bit.

One minor complaint, not even really a complaint, that has driven me bonkers since I first used this applet; the pie chart for memory usage. I like having a short history and can see if there is a misbehaving app (or my own dumbness) has caused a memory usage spike. Could you please either change it or give the option to use a plotted graph like the network and disk monitors use? Thanks and thanks for the great monitoring applet!

No, it works for me. Open an issue and include the output of inxi -F && dmesg | grep -i error

It looks like the mint control panel is installing an older version so just just remove Multi-Core System Monitor in mint control panel, download zip manually from this site and unzip it to ~/.local/share/cinnamon/applets. :)

Did work for me, right now. Thank a lot ! :)

The changelog info is from the original author. The newest version is 1.6 which does support 3.4. Please check for an update in System Settings -> Applets.

I think your latest upgrade may've broken something (leastwise, on my machine). Trying to add the applet errors out and the error message given in glass.log is "error t=2017-06-04T01:19:19.277Z Mainloop.idle_add_full is not a function". I'm running Linux Mint 18, version 3.0.7. If there's any further info. you might need or tests to run, let me know and I'm more than happy to help.

Great applet. Feature request, I'd love to be able to specify a refresh rate greater than 1 second (1000ms) in the GUI. When running Mint in a VM I don't need to have a very accurate current CPU or memory load.

Jefferson Davis-8 years ago

Cinnamon now at version 3.4.0

Jefferson Davis-8 years ago

And, it's been fixed, apparently. Try removing it from the installed apps, go to online list, refresh, and reinstall. It also appears cinnamon itself was updated, so perhaps that's part of it?
