Here's the backtrace. If I run:
sudo gdb --args /usr/lib/xorg/Xorg -nolisten tcp :1 vt2 -keeptty -logfile xorg.log on terminal and on another terminal run: export DISPLAY=:1 gnome-session it crashes and the backtrace full is attached. But if I just run: export DISPLAY=:1 gnome-shell it doesn't crash but loads gnome-shell. So the problem only shows up in gnome-session, that's probably why gdm3 starts fine, but when logging in as a user, it crashes. ** Attachment added: "xorg.crash.bt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1868561/+attachment/5340608/+files/xorg.crash.bt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1868561 Title: Xorg Crash on login To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1868561/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
