> gnome-session is innocent here. It's being asked to start a GNOME x11 session but there doesn't exist one, so it gives up.
But what is doing the asking? Given this machine has Nvidia and was installed back in 21.10, perhaps some leftover udev rules that never got upgraded or removed. Marcos, do you remember if you have ever customised the files in /usr/lib/udev/rules.d/ ? Please run this command: grep -l nvidia /usr/lib/udev/rules.d/* and attach any files that match the search. -- You received this bug notification because you are a member of Debcrafters packages, which is subscribed to gnome-session in Ubuntu. https://bugs.launchpad.net/bugs/2122294 Title: gnome-session-init-worker crashes with SIGTRAP (Failed to start unit [email protected]: ...: Unit gnome- [email protected] not found.)

For some reason it seems it was in a crash loop. Normally after the boot it appears turning on my external display, and than appears the GDM. But this time it entered in a loop turning on and off my external display. I can say that because appears an OSD written "HDMI 2" when it turns on the display. I hope the logs can give you more details about it.
