I wanted to start a topic about this problem I’m having because I’m one of the few people it seems that needs to have custom gamma settings set at launch and during desktop use.
What I experience atm is a problem where opening a program like Vivaldi/Chrome/Gedit etc will very often reset the gamma settings to 1.0 instead of my custom 0.850000 setting.
I have a autostart script that exec the following commands at launch, and it does work until I open something, yes I’ve tried each command separately. (cmds tested separately also)
xgamma -gamma .85 &
nvidia-settings -a 0/AllowVRR[DP-4]=1 -a 0/ShowVRRVisualIndicator[DP-4]=1 -a 0/ShowGraphicsVisualIndicator[DP-4]=0 -a 0/RedGamma[DP-4]=0.850000 -a 0/BlueGamma[DP-4]=0.850000 -a 0/GreenGamma[DP-4]=0.850000 &
However these do not persist and I’m forced to go into console and issue them again after loading up a program. Sometimes what also happens is the gamma controls LOCK UP entirely and I can’t change them without restarting X.
.nvidia-settings-rc exists and has the correct settings.
To me it seems that nvidia drivers or settings are not persistently applied like how it is with windows where if you load a program that adjusts gamma, then quit, it will reapply your custom gamma settings.
This is quite an annoying issue and I have pretty much tried everything in the books to resolve but the resetting of my custom gamma (and other settings for that matter) keeps happening. Its as if the nvidia drivers are switching to default options often.
This problem exists on gnome/xfce/plasma5, and has existed in previous vulkan beta drivers, I believe its a driver BUG that has not been caught by nvidia.
