So I have run into the, many, issues of games running incredibly slow. So I eventually landed the fix of manually installing the nividia driver, on the manual search "GeForce RTX 30 Series | GeForce RTX 3060 | Linux 64-bit", a few, notable, features do not work anymore
That being the Zorin Desktop Enviornment, it would seize up and be unresponsive
And Flatpak's freezing the whole PC
I have discovered that using sudo apt install xfce4 has helped me actually use it. Along with .appimage files to what I use being a functional, and surprisingly unbothered, alternative
Are there still issues with the Unbuntu drivers, as it would not use the recommended driver from the manufacturer, or is it okay to use the official drivers, from Unbuntu, of the same version (that being driver version 595.99.02 as of this time of typing) in order for the regular desktop and flatpaks to work well again?
yeah dont use the nvidia .run installer on zorin. thats what broke the desktop and flatpak.
the .run dumps its own xorg/dkms stack and gnome just eats it. xfce surviving after that is pretty common.
uninstall that first:
sudo nvidia-uninstall
then use the distro package of the same version (595.xx), additional drivers or:
sudo apt update
sudo ubuntu-drivers autoinstall
reboot. desktop + flatpaks should come back. the ubuntu/zorin 595 package is not the same as the manufacturer installer even if the version string matches. stay on the packaged one.
I am running on Nvidia-driver-595 due to the Nvidia-driver-610 being exceptionally buggy with RAM dumping and many other issues. It is also conflicting Steam Shaders.
I would suggest at least to try the Driver in the Repos. There tested. So, the Experience can be different - hopefully better - for You.
Also: Could You exactly say Brand and Model of Your Graphics Card? Are Secure Boot and Fast Boot in BIOS disabled? Does Your System run in Wayland or X11? You can check that with the Terminal Command echo $XDG_SESSION_TYPE
I don't know if this will help but I have a RTX 4080 Super and I am on the 580 branch using Nvidia driver 580.173.02 and I have no issues with flatpak Steam running games: CP2077, Oblivian Remastered, Baldur's Gate 3 and Starfield.
