Public bug reported: I am running Ubuntu 22.04.2 LTS on a Dell 5410 laptop. Typically it is connected to a Dell WD19 docking station with an attached monitor.
I have been having issues with using two monitors at once since a recent security update to several xorg packages. Since the update of: Upgrade: xserver-xorg-core:amd64 (2:21.1.3-2ubuntu2, 2:21.1.3-2ubuntu2.9), xserver-xorg-legacy:amd64 (2:21.1.3-2ubuntu2, 2:21.1.3-2ubuntu2.9), xserver-common:amd64 (2:21.1.3-2ubuntu2, 2:21.1.3-2ubuntu2.9), xwayland:amd64 (2:22.1.1-1, 2:22.1.1-1ubuntu0.6), xserver-xephyr:amd64 (2:21.1.3-2ubuntu2, 2:21.1.3-2ubuntu2.9) sometimes only one monitor works at a time: the external one when the docking station is attached and the internal screen when not. Several times, after a reboot - only one monitor was available. When only one is working the display settings show there only being one monitor. Sometimes both work for a while, and then the problem starts. It is not clear to me what triggers the problem. Once the bug triggers, disconnecting the laptop from the docking station and reconnecting does not seem to get the system back to using both monitors at once. Detaching and the reattaching the monitor from the Docking station helped once. After a downgrade back to the versions - things seemed to work fine again. I downgraded to the following package versions to avoid the issue Downgrade: xserver-xorg-core:amd64 (2:21.1.3-2ubuntu2.9, 2:21.1.3-2ubuntu2), xserver-xorg-legacy:amd64 (2:21.1.3-2ubuntu2.9, 2:21.1.3-2ubuntu2), xserver-common:amd64 (2:21.1.3-2ubuntu2.9, 2:21.1.3-2ubuntu2), xwayland:amd64 (2:22.1.1-1ubuntu0.6, 2:22.1.1-1), xserver-xephyr:amd64 (2:21.1.3-2ubuntu2.9, 2:21.1.3-2ubuntu2) and after reinstalling the updates again experienced problems. It seemed that things were fine when xserver-xorg-core:amd64, xserver-common:amd64, xserver-xorg-legacy:amd64, server-xephyr:amd64 were all on version 2:21.1.3-2ubuntu2.7 and xwayland:amd64 was on version 2:22.1.1-1ubuntu0.5 but I am not sure about with 2:21.1.3-2ubuntu2.8 as I do not think the system was restarted after the update from 2:21.1.3-2ubuntu2.7 to 2:21.1.3-2ubuntu2.8.
