Last commit: [021e8ae8] Hungarian translation update for Cinnamon Desklets (#1806)

Creates graphs for system variables.

README

System monitor graph Desklet

Desklet to show graphs for the level of activity in various system variables including: CPU, memory, network and disks. The desklet supports multiple instances with different system variables with the idea of presenting them in a uniform way.

Four instances of the Desklet in action.

This project has been inspired from other Desklets such as Disk Space, CPU Load, Simple system monitor, Network usage monitor, Top, and the Rainmeter Win10 Widgets.

Features

Variables to monitor (v2.0 - July 2025)

System variable	Description
CPU	CPU usage in %
CPU Temperature	CPU temperature C or F
RAM	Used RAM as % of total, and in GB
Swap	Used Swap space as % of total, and in GB
HDD	% of I/O activity, and free and total space in the filesystem (partition) indicated by the user
GPU Usage	GPU usage in %
GPU Memory	GPU memory usage in %
GPU Temperature	GPU temperature C or F
Network	Real-time upload and download speeds with dual-line graph, configurable interface monitoring
Battery	Current capacity %, and Status

Each variable is calculated every Refresh interval seconds (Min. 1 s, Max. 60 s.), and the graph shows the last Duration of the graph period (Min. 30 s, Max. 60 min). GPU graphs work for NVIDIA, discrete AMD and built-in AMD.

Customizable visual elements

Settings for one instance of the system monitor graph Desklet.

Great desklet! I'm noticing that the graphs flows from right to left and I'm wondering if you could make the pertinent numbers above line up with the point of origin of that flow and make it possible for users to specify right-align or left-align. In my case I line up the applet with the right side of the screen, but if I want to see the "numbers", I have to shrink the size of my open windows to be able to see them because they are on the left side of the applet window. I know I can shrink the desklet, but then the graph and text starts to get pretty small. To me the logic would be to show the values right above where they actually show up on the graph, you know. I have other applets lined up with the right side, but yours doesn't allow drag-resizing so you have to make it really small so all these monitoring applets fit nicely on the right side. Thanks!

Loving this, however I have a spall issue with HDD. It's working fine for all my other partitions, however when i select "FileSystem" to show space on the main OS drive I get no data showing. Any ideas what that would be? It's an LVM volume if that matters?

justinlindtx-2 months ago

Love this desklet! I would love to see better support for multi-monitor setups, though. Plugging a second monitor into my laptop moves the graphs to a completely different location on the other screen.

Heya, how do I find my GPU ID to get my AMD GPU usage to show in your lovely little applet?

Hello, check this post in GitHub https://github.com/linuxmint/cinnamon-spices-desklets/issues/1550#issuecomment-3215461823

Shuaib Kunji-4 months ago

Man I absolutely love this one! Everything I need to see without feeling overwhelmed. Just the perfect amount of information with sufficient customization. Well done, devs! Well done!

I use AMD Radeon 5700 XT and that card do not have any usable ID that i can put in . Chip ID and bus do not work (obviously) . Did you make auto recognition, coz it isn`t work out of a box?

Raymundo Cassani-3 weeks ago

Hello, there is not auto recognition, you need to check the sysfs path for your card, and from there get the card id. Check this post in GitHub https://github.com/linuxmint/cinnamon-spices-desklets/issues/1550#issuecomment-3215461823

samikaz87-8 months ago

great tool. Thank you. Would love to have Fan Speed as an option in the future for CPU/GPU

Kai Diestelmeier-8 months ago

Probably a stupid question, but: how do I get more than two graphs? Using the "next instance" pointer at the top toggles between the two existing graphs "CPU" and "RAM"; switching from say CPU to SWAP just changes the existing graph instead of creating a third instance. What am I missing?

Kai Diestelmeier-8 months ago

Found it; clicking in the "Desklets" admin window on "Add to desktop" several times adds several instances ...

remixedcat-8 months ago

stopped working with the latest update and now I wish I hadn't updated it. I'm on Linux mint 20 and can't upgrade till I get a new SSD which won't be for 3 weeks approx.

Xanhedonic-8 months ago

How do I make HDD to show, write/read ? There is option to select that... Also, how to make GPU show usage? GPU graph doesn't work at all, how do i find the id of my AMD gpu? Tried the lspci command, but it doesn't show the goddamn id, just the name of my gpu. (RX 6700 XT)

XG0MERX-8 months ago

I'm having the same issue with GPU monitoring

Brett Fox-9 months ago

Oops, I found it! Let me know if I can help you directly otherwise I will post in github. Thanks again for simple reliable and elagant!

Brett Fox-9 months ago

Hi mate I love this desklet! I use it on three pc's, literally 10 instances for one machine :) I would love to have a network monitor version. Do you have a repo? I am happy to contribute :)

Harrison Howard-10 months ago

This has stopped working for me. All desklets appear off the screen and clicking "Configure" brings up no modal. I've tried uninstalling it, removing all my desklets and this does not work anymore for me.

Harrison Howard-9 months ago

Seemed to have resolved it. But seems like an issue with cinnamon and docking different monitor configurations.

sleekspeed22-11 months ago

Is % of I/O activity working for anyone else? I see nothing here I set the Filesystem to monitor to File System as that seems most broad but I'm not seeing any I/O activity. CPU and GPU seem to work. I also check with iostat -d in terminal and can see data.

Harrison Howard-11 months ago

Hello, I would like to know when the following features will be available. - GPU & CPU Temperatures - Network usage

Ken Walker-1 year ago

Just updated and after removing all the desklets, none of the system monitor ones are visible anymore when I add them. Nvidia GPU. Not sure if it has to do with the new Cinnamon patch today or not.

Raymundo Cassani-1 year ago

This is fixed now

DemittiNix-1 year ago

Ram and GPU broke on update. I also have a Nvidia GPU.

DemittiNix-1 year ago

Fixed now. Thank you!

Alex W-1 year ago

Ram seems to work for me, but not GPU (Nvidia also). Hopefully fixed soon

Raymundo Cassani-1 year ago

This is fixed now

visorroK-1 year ago

Latest update broke GPU monitoring, at least on my NVIDIA GPU. Keep up the great work. Thanks!

Surmallion-1 year ago

On my computer NVIDIA GPU display in this desklet also broke after this last update.

jarama-1 year ago

for me too, I had multiple desklets running for my various systems but I had to disable them all now unfortunately

Raymundo Cassani-1 year ago

This is fixed now

Qjr-1 year ago

I have 2 questions. 1. When will there be a network preview? It was announced 3 years ago and it's still not there. 2. I connected another monitor and my desklets are missing. Is there a configuration file with the add-on positions? Because I would like to see where they might be hiding somewhere outside the workspace.

circuitsystem-1 year ago

still no GPU monitoring for AMD cards :C

Raymundo Cassani-1 year ago

From Feb 2025 they are supported

circuitsystem-7 months ago

tried using gpu monitoring again with a new GPU. It was working yesterday aaaaaand this morning its not. neither gpu usage nor vram are showing. just NaN%

Tobbi80-1 year ago

It's perfect. Please add battery usage... The will be Fantastic.

Raymundo Cassani-1 year ago

Interesting feature

Andre Verwijs-1 year ago

please add network monitoring .... thanks

Luiz Fellipe Carneiro-1 year ago

First, thanks for the nice graph. I want to see my GPU stats, but here it only let me pick NVIDIA but my GPU is AMD.

Will Hedges-1 year ago

Same here - were you able to find a fix? I saw below the developer hasn't added support for AMD yet but

Raymundo Cassani-1 year ago

From Feb 2025, AMD GPUs are supported

OCTOGONE.dev-2 years ago

Hi, thanks for this desklets. Can you make an option for a transparent background like "Disk Space" by schorschii? THnks

Rick Calixte-1 year ago

It's not perfectly intuitive but the color chooser already supports transparency. If you right-click on a color in the color chooser and select 'Customize' (as the only option), the bar/switch at the bottom is the alpha/transparency setting. If you right-click on the knob, an option to manually set the alpha/transparency will appear and you can enter the desired numerical value there.

Jaroslav Pánek-2 years ago

Unfortunately in Linux Mint 21.2 Victoria this desklet causes video stuttering in any browser. After uninstallation everything is fine.

Andre Verwijs-2 years ago

please add network monitoring .... thanks

supriokundu-3 years ago

Hi, First of all I'd like to thank you for creating this very useful and customizable monitoring tool. It consumes very little resources compared to a similarly functioning conky config. I was using it to monitor CPU, MEM, GPU and Filesystems and it was working fine but as I've swapped my GPU from GTX 1070 to RX 590, the GPU monitor won't work anymore, it is only having as option for NVIDIA not for AMD. I want to know that if there are any issues in my system itself or it is expected behavior? If the 2nd is true, is it possible to add AMD support to this wonderful desklet?

Raymundo Cassani-3 years ago

For the moment, the desklet does not have support for AMD GPUs. I don't have one at hand, and I'm not sure how to monitor its status in the way nvidia-smi does for NVIDIA GPUs

supriokundu-3 years ago

Thank you very much for your response, I've made my own conky theme to monitor various hardwares on my PC, which includes my RX 6600 GPU. I've also done the same for RX 500 series GPUs. Its shows numerous parameters of my GPU like current load in %, core temp, fan speed, core and memory clock, total power etc. But conky consumes way more (CPU) resource to show them compared to your desklet. So, if you want I'm ready to share my knowledge with you which might be helpful for you. I'm not that proficient in coding to build a desklet my myself.

Raymundo Cassani-1 year ago

From Feb 2025 AMD GPUs are supported

Raymundo Cassani-3 years ago

It sounds great! Please send me an email, my info is in my GitHub profile

PRSoftware-3 years ago

Hello, For HDD monitoring, you chose to display data with units powers of 1000 rather than of units powers of 1024. For example, your desklet reports 526 GB free on my disk but the file manager and all other tools report 490 GiB which seems to me more accurate. Is it possible to add a feature to choose the display unit (GB or GiB) ?

Raymundo Cassani-3 years ago

Done at https://github.com/linuxmint/cinnamon-spices-desklets/pull/822

krasotaa-3 years ago

There's something wrong with this desklet, I was working on animations with css in firefox and they weren't fluid, so what solved it was to remove this desklet, because I remembered that there was a warning about crashes in that desklet. My computer has a ryzen 5 2600 and a gtx 1660 super. Weird.

PRSoftware-3 years ago

Hello, One year ago, I asked if the network monitoring was planed to be added in this fabulous desklet. You answered that it was the next feature... And now ? Is it still in your plans ? Thanks by advance.

fafke-4 years ago

Hello mister R. Cassani This is my favourite desklet and love to see some addings. Is it possible to add Cpu temperature en Gpu temperature. This is because i have them now as applet but when i go full screen i cant see them anymore. I have multiple screen setup so when i go fullscreen i can see them on my other screen. hope to here from you !

Chaturanga42-4 years ago

I'm on Manjaro Cinnamon and after updating desklets today, yours stopped working. Can you give me any pointer on how I can find out, whats wrong?

Chaturanga42-4 years ago

They have disappeared from the desktop, when trying to add them from cinnamon "Desklets", no desklets are getting created. Pressing "configure" button in the same window, does not have any effect as well.

quamok-4 years ago

nice desklet, but the HDD option doesn't seem to be working for me. It stays stuck at the CPU graph, frozen. All other system variables are working properly. Anyone else experiencing the same issue?

simonmicro-2 years ago

Yes, similar problem. HDD just stays at "0 GiB free of 0 GiB" with 0% usage. Does not seem to matter with directory to select...

Nazarii Oliinyk-4 years ago

Can you make video tutorial "How to make your own desklet" ?

Raymundo Cassani-4 years ago

I wrote these posts, they are not extensive, but can help you to start: https://www.castoriscausa.com/posts/2020/05/12/cinnamon-desklet-development/ https://www.castoriscausa.com/posts/2020/06/09/system-monitor-graph-desklet/

Nazarii Oliinyk-4 years ago

Very cool desklet. Fulled customization. Thanks.

AlexWhiteSe-5 years ago

Could you please add temperature stats for CPU and GPU ?

ARNOLD Somogyi-5 years ago

The latest update does not work with Linux Mint 20.1 Cinnamon. I just updated my Mint Linux, then updated this desklet, and it disappeared. Mint says that "This desklet contains function calls that could potentially cause Cinamon to crash or freeze. If you are expecting crashes or freezing, please try to remove it." Could you please fix this? This is my favorite desklet and I would like to use it. Thx. Version: Version 1.2 (2021-02-06 16:15:34)

Raymundo Cassani-5 years ago

Even with that warning you should be able to use the Desklet. I haven't find the culprit yet.

AlexWhiteSe-5 years ago

I have same OS version and there are freezes every second

PRSoftware-5 years ago

An other suggestion: could you add the possibility to launch an application (by default gnome system monitor for example) when left clicking on the desklet.

PRSoftware-5 years ago

It is a very good desklet : clean and easy to use. As asked by other users, could you first add the network monitoring (DL and UL speed) in the next release ? The temperatures would also be a great feature but less important than network for me ... You did a great job !

Raymundo Cassani-5 years ago

Yes, network monitoring will be the next feature

CrazyFoxSR-5 years ago

Please can you make network monitor next. I am useing it from since i swiched to cinemon and i like it .

Raymundo Cassani-5 years ago

Yes, network monitoring will be the next feature.

pabloantunes-5 years ago

This desklet with a transparent background would be great.

Raymundo Cassani-5 years ago

The Desklet supports transparency. Just pick a custom color and move the transparency slider.
