Bug Description
This bug is encountered on a computer with:
Kubuntu 21.10
MSI Gaming X Trio 3060 Ti
The following repo is used:
ppa: kubuntu-backports
GPU driver:
Nvidia driver metapackage from nvidia-
What I expected: SDDM working just fine, showing every elements
What happened: SDDM is showing a black screen on login, logout, lockscreen. BUT logging in works.
What I did: Updating nvidia-driver-470 from 470.63 to 470.74
What I tried to do to fix: dpkg-reconfigure sddm
I suspect something is conflicting SDDM with the 470.74 driver. Downgrading to 470.63 will fix this problem.
