"Failed to start light diplay manager" after an upgrade

[FredJ]

Kali Rolling Realease 2022.4
Computer : Asus UX32V with Nvidia
nvidia-detect : Nvidia GF117M (620M GPU)



Hi,


After an update (sudo apt full-upgrade) it's impossible to restart with GUI.
I purged Nvidia drivers, reinstalled them, reconfigured lightDM...
Nothing works.
I searched on the internet some solutions....


It's my everyday computer, so, I hope you can solve that bug!
You are my only hope!

With @steev from Kali bug tracker :
$ sudo apt policy kali-desktop-xfce
kali-desktop-xfce:

=> /!\ xfce is not present anymore!!!
And it's not the known bug with libllvm.

$ sudo apt install kali-desktop-xfce xserver-xorg-input-all xserver-xorg-video-all
Many thanks @steev. I continue to troubleshoot.
