By default the gamma setting of 1 makes the blacks on my display device way too dark. They are dark to the point where all detail is lost. My display only allows brightness manipulation which does nothing for those lost details. No problem though because the nvidia-settings has a gamma setting and works as intended. However, anytime I log out, restart or the display goes to sleep, the gamma goes back to 1.0.
Things I’ve tried:
- I opened nvidia-settings from terminal using sudo nvidia-settings, which didn’t work.
- I followed the manjaro wiki Configure NVIDIA (non-free) settings and load them on Startup, just in case the gamma portion did work on Cinnamon. It didn’t.
- I tried to change the setting with xgamma. It changed it just fine, just didn’t keep the setting after reboot.
- I added # gamma 1.3 (also tried without #) to /etc/X11/mhwd.d/nvidia.conf with the same results
- I added # gamma 1.3 (also tried without #) to /etc/X11/xorg.conf.d/90-mhwd.conf just in case even though it links to nvidia.conf. Didn’t work.
- Switched over to the 5.4 kernel. That didn’t work either.
Things I haven’t tried yet
- Redshift. Apparently you can set it up for gamma on a timer. I’ve read other posts saying it worked for KDE Plasma, but not gnome. Given Cinnamon is GTK, I’m guessing it would go the way of Gnome.
- Kernel 5.9. Im not a fan of experimental kernels… but I’m getting to that point.
Anyway, anyone have experience with this? Am I just missing something simple?
