GNU Linux/Workarounds

A lot of distributions come fairly close to being perfect, but sometimes workarounds are required to improve the user experience. Please note that these are filed under distribution and driver specific sections, so may or may not be suitable for other combinations.

Wayland User Experience

Lag with NVIDIA GPU's

If you have an AMD graphics card, either integrated or dedicated, you will likely be accustomed to having a better user experience than those with NVIDIA graphics cards.

Wayland works pretty well, but memory and other clock settings stay at too low of a frequency, causing lag. This is noticeable with the GNOME desktop shell. I use this code below to increase the minimum clock speeds on my dedicated GPU.

sudo nvidia-smi -pm 1
sudo nvidia-smi -lmc 1000,6000
sudo nvidia-smi -lgc 1000,2000

The first command enables the persistence mode daemon, which keeps the kernel mode driver running (even when no other application is actively using it), the second locks the memory clock between 1000 and 6000 MHz, and the last, locks the graphics clock to be between 1000 and 2000 MHz.

OpenGL/X11 Application Not Running With a Dedicated NVIDIA GPU

I encountered this issue when running Freecad, which, in my case, could not use my dedicated GPU due to initialization issues with the OpenGL Extension for X11 (GLX). I use this code below, within a script, to ensure Freecad's rendering path goes a different way:

Xwayland -decorate -geometry 1920x1080 :2 &
QT_QPA_PLATFORM=xcb prime-run freecad -display :2
