I have upgraded my Ubuntu to 22.04 from 21.10. Firstly, everything seems working but Ubuntu was not smooth and started to stuck while working. Then I decided to check display card driver and I have noticed that I use XOrg driver instead of Nvidia. Then I installed nvidia driver but now my HDMI and DP monitors does not work. I had a similiar issue before and I asked it here => HDMI does not work on Ubuntu 21.10 My kernel version is: 5.17.0-5.1-liquorix-amd64 and my bug report attached. nvidia-bug-report.log.gz (88.6 KB)

Please check if switching to performance mode improves the situation sudo prime-select nvidia Furthermore, please set kernel parameter nvidia-drm.modeset=1

Running $ sudo apt update $ sudo apt upgrade $ sudo apt autoremove $ sudo apt-get remove --purge nvidia* $ sudo apt-get remove --purge "nvidia*" $ sudo apt install nvidia-driver-510 (you may need other version) $ sudo reboot these commands solved HDMI and DP problems but now ubuntu is not smooth again. Here is new bug report: nvidia-bug-report.log.gz (342.6 KB)

kernel parameter already has been set but changing to performance mode made a huge impact. thank you, sir. but sometimes, ubuntu freezes and I can not do anything. no mouse or keyboard interaction. do you have any suggestion for this situation :)

Does it unfreeze after a few seconds or does it stay frozen? Please create a new nvidia-bug-report.log

No it does not unfreeze, I have to power-off the computer by keep pressing on power button :( Bug report attached nvidia-bug-report.log.gz (379.8 KB)

unfortunatly, no errors are logged. Please check for a bios update.
