Linux Mint 21 bug: hovering over applet and using mouse-wheel to increase/decrease brightness is broken (doesn't properly does it, in small steps).

Was using the Gammastep to adjust my screen brightness, since redshift is not responding to my commands, telling me i was using wayland so i stumbled upon this and it works perfectly on my device. Plus the UI is on point straight. thanks for this.

Hello, a small issue with version 1.1.2 under Linux-Mint 21 When putting the mouse cursor on the applet : 1) Pushing the mouse wheel backward to decrease the brightness is well working. 2) But, after that, re-pushing the mouse wheel forward to re-increase the brightness is not working. Thanks ;-)

Great applet! Exactly what I was looking for to change the brightness of my three monitors all at once. :) Thank you for making it!

Theres a confussion: Gamma is not RGB. This app offers the brightness and RGB levels, not gamma adjustments. (i might be wrong about tecnicities, but looking to adjust my gamma settings this app don't do as expected.)

Tried to improve this applet. Still a work in progress. Hopefully the author/maintainer would fancy the ideas. There is a newer version but waiting for feedback on a SVG issue: https://github.com/linuxmint/cinnamon/issues/9912#issuecomment-774509791 Here is my humble contribution: https://forums.linuxmint.com/viewtopic.php?f=120&t=341630

This applet is wonderful. Please consider adding the ability to adjust the temperature and humidity outside. ;/

I'm curious why this applet works the way it does... I also installed QRedshift - which enables me to switch the setting (i.e. dim the screen) with a keyboard shortcut, also right click to restore the 'default' (transparent) daytime setting. So what does this applet offer?

Excellent applet, works perfectly, thank you for this software.

Excellent. Why not add gamma setting? This should be integrated into the Linux Mint because it is 21st century.

This works perfectly, and is simple to use. Thank you!

i changed the settings and now don't know how to reset them to default.

Is it intended that this only operates on one monitor at a time? I have to switch back and fourth between outputs to adjust each screen. My feature request would be to add a "lock" option where all outputs are synced. Thanks for the applet cardsurf!

Thank you very much. However, upon using it for a 24 hour long, the LCD monitor screen would slowly be brighten back to 100 percent. I would need to keep changing it back to 60 percent every hour or so. If I play Starcraft 2 on PlayonLinux, the brightness would bounce back from 60 percent to 100 percent right away.

Thank you very much for this very nice applet !! But why lower limit is just at 30 ?? Can you please make it 20 ? Best

Exactly what I wanted. Thanks cardsurf for a perfectly simple applet. For months I have been using xrandr from the command line to adjust my external monitor's brightness. This is so much nicer.
