Issues

NVIDIA, graphics card manufacturer popular among Windows gamers has a number of problems on Linux:

• NVIDIA does not support Wayland
  • NVIDIA Driver v470 rumored to have Wayland support
• Good luck getting HDR to work
• Good luck getting Adaptive FPS (i.e., FreeSync/GSYNC) to work
• Kernel updates occasionally break driver
• vfio requires resorting to vendor spoofing hacks
  • GPU passthrough for Windows enabled (Level1Linux take)

Sometimes, a simple reinstall of the driver is enough. In openSUSE:

sudo zypper in --force $(rpm -qa "nvidia-gfx*kmp*")

AMD

AMD open source graphics driver is known to work reliably and improve over time.

• An alternative: prevent kernel updates temporarily by locking the kernel with zypper al kernel-default.
  • You can update the rest of your programs normally while the driver makes its way over to the stable release channel.
  • Remember to remove the lock if you use this approach.
