This issue hit me yesterday also. $ lsb_release -rd No LSB modules are available. Description: Ubuntu 24.04.2 LTS Release: 24.04
- Attached the journal.txt and prevjournal.txt. - No crash file found in /var/crash. - No relevant file found in https://errors.ubuntu.com/user/ID. The only workaround I found was to install lightdm and to switch from gdm3 to lightdm ("sudo dpkg-reconfigure lightdm"). No other tricks given in this ticket or in the page https://bugs.launchpad.net/ubuntu/+source/gnome- shell/+bug/2089709?comments=all worked for me. To be able to switch back to gdm3 login again, I found out that in the file "/etc/gdm3/custom.conf", the "WaylandEnable" line was commented. I have no idea why, because I never modified this file before: # Uncomment the line below to force the login screen to use Xorg #WaylandEnable=false After uncommenting this line, and rebooting with gdm3, I landed again on the login window as expected. I also noticed that when I was trying to login via gdm3, using Wayland instead of X11 (WaylandEnable=true), then I would fall back on the same initial issue, no login screen, just a black screen with a mouse cursor. Essentially same failure as if I had that commented line "#WaylandEnable=false". I suspect that one of the latest Ubuntu update forced to use Wayland instead of X11 for the login screen, by commenting the line "#WaylandEnable=false ". And apparently, Wayland login would fail to launch on my system. ** Attachment added: "journal_with_pre-journal.zip" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2089709/+attachment/5866763/+files/journal_with_pre-journal.zip -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2089709 Title: Ubuntu 24.04 (X11) sometimes logs in to a black screen with only an X cursor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2089709/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
