Installing Displaylink drivers on Ubuntu 22.04 breaks gdm3/Xserver
2 Attachment(s)
Originally installing the DisplayLink drivers worked fine.
After some time of using it suddenly (supposedly after some unattended upgrade), Ubuntu would boot into a blinking _ and not start the GUI. After some debugging, I figured out: * the issue exists independent of whether displaylink display is attached or not * the issue only exists when displaylink drivers are installed * the computer boots as expected when they are uninstalled * the issue persists independent of the window manager gdm3 and lightdm won't start * the issue exists for 5.5, 5.6 and 5.6.1 of the displaylink drivers * the issue exists for both Xserver and Wayland, i.e. changing WaylandEnable=false in /etc/gdm3/custom.conf Ubuntu 22.04 with 5.15.0-58-generic, Thinkpad laptop with and ryzen 4000 series and gpu I attached a lot of logs and the output from the debug info tool while having set lightdm as the window manager. Journalctl shows lightdm.service and gpu-manager.service crashing. I attached the logs of them. |
Solved
Due to a coincidence I had some problems with the AMD driver leading to me changing the installed mesa version from 23 to 22. This allowed me to install the dp link driver.
