Migration from Leap 15.5 to Leap 15.6 using the upgrade fails due to Nvidia Drivers.
Leap 15.6 boots into command line mode after upgrade reboot.
The message in the log is not very helpful: “prime-select system_call (code=exited, status=1, FAILURE)”
The NVIDIA drivers need to be reinstalled. Probably a licensing issue.
Search for installed Nvidia drivers using “zypper se -s nvidia” or similar.
Uninstall the Nvidia drivers using “zypper remove xxx”.
Re-Install the Nvidia drivers from the command line using this guide: SDB:NVIDIA drivers - openSUSE Wiki
Check the driver config for the GPU using inxi -G.
Follow the instructions here for setting up Prime - SDB:NVIDIA SUSE Prime - openSUSE Wiki
Delete the X11 files.
Run “prime-select boot nvidia” as per the instructions.
Restart. KDE should launch.
Check to see if the NVIDIA driver is in use.
inxi -G
