Thanks. Yes, I think the Xorg crash shown in comment #13 is the important one here. Unfortunately it is "strange" as you say, because debug symbols are not installed.
Next please try installing the debug symbols: https://launchpad.net/ubuntu/+archive/primary/+files/xserver-xorg- core-dbgsym_1.20.9-2ubuntu1.2~20.04.1_amd64.ddeb and then send us another: journalctl -b-1 > prevboot.txt ** Summary changed: - [DisplayLink] Desktop crashes and return to login screen + [DisplayLink] Xorg crashes and return to login screen -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1914573 Title: [DisplayLink] Xorg crashes and return to login screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/evdi/+bug/1914573/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
