Nvidia GPU optimisation error

[enesdogan00]

Describe the bug When I enable GPU optimisation it gives an error. Other settings works just fine. I installed the software from AUR (non-git version).

gamemoded -t output:

Hello, Same here, with GameMode v1.6, Kubuntu 20.04 kernel 5.4.0-47-generic, KDE Plasma 5.18.5, NVidia GeForce GTX 1050 Ti and NVidia proprietary driver version 450.66.

You get this error because overclocking is not enabled for your GPU so that value is empty, you need to enable Coolbits to get this to work, most likely set Coolbits to 8, instructions here: https://wiki.archlinux.org/index.php/NVIDIA/Tips_and_tricks#Overclocking_and_cooling After changing the Coolbits options either restart your computer or relog and in the Nvidia-settings panel in Powermizer section you should see and it should work now.

Also, for anyone using KDE there's a bug in 5.20.5 where GTK applications output extra debug information which also messes up Gamemode from changing Nvidia settings. Example:

$ nvidia-settings -q [gpu:0]/GPUGraphicsClockOffset[3] -t
WINDOW DECORATIONS RELOADED
WINDOW DECORATIONS RELOADED
0

It should've returned just 0. It was fixed upstream so just hope 5.20.6 will come soon. https://www.mail-archive.com/kde-bugs-dist@kde.org/msg520023.html
