Comment # 12 on bug 1198545 from Sotir Danailov

I removed "nomodeset" and I uncommented the nvidia-drm option and ran mkinitrd,
after the reboot, the login prompt showed up, but when I tried to login,
everything froze and this are the log messages:

I stopped the machine by holding the power button. After this I started
Tumbleweed in "Recovery mode", when the login prompt showed up I pressed
ctrl+atl+F2, I logged in successfully and again commented the nvidia-drm
option, ran mkinitrd, rebooted again and this time there was no issue.
