2 months ago Solved it by this, found on nvidia website forum and did the job:
sudo prime-select nvidia
grep nvidia /etc/modprobe.d/ /lib/modprobe.d/
to find a file containing
blacklist nvidia
and remove it, then run
sudo update-initramfs -u
and reboot
Describe the bug It worked perfect under Ubuntu 22.04, but I installed Ubuntu Studio via the Installer. After reboot Brightness controller does not see my screen and hence I cannot control it. Uninstall and reinstall and reboot did not help.
version I think the latest, the about screen became white after I clicked on the github link
To Reproduce Install Ubuntu Studio over Ubuntu 22.04 via the Installer
Expected behavior Working as usual
Screenshots In this case that would not help.
Desktop (please complete the following information): Ubuntu 22.04
Additional context It's an ASUS TUF AMD with AMD and NVIDA RTX 3050. The Nvidia seems to control the brighness.
