Description Patrick Lang 2024-06-18 04:57:44 UTC 
As of kinoite version 40.20240529.0, KDE Plasma will no longer start up. It hangs at a black screen with a non-moving cursor, and I cannot get control of the VM even on a regular VT. SSH connections are still working, so I have collected some logs.  The previous ostree  40.20240527.0 does not exhibit this problem and is the last known good one on this setup.


This log snippet seems to show the failure. I have attached more logs as well.
