Potentially relevant: I had to recompile and reinstall the evdi kernel module while booted into 5.10 because when I install the 5.11 kernel dkms removed the module from 5.10 and then failed to rebuild it because the 5.11 build failed (or something I don't really understand why dkms does what it does *sigh*). I don't see how that should matter because the recompiled version of the module should have been identical, but *shrug*. As noted above, when I remove the evdi kernel modules from /lib/modules and reboot with 5.10 the problem goes away, so this does appear to be an evdi issue. In short: despite the fact that it's not clear how upgrading any of the modules listed above would cause evdi that used to work to suddenly stop working, that appears to be the case. Any advice would be appreciated because now I can't use the displays connected to my DisplayLink hub with either 5.10 or 5.11 kernels, despite the fact that they worked with the 5.10 kernel before today.

[Touch-packages] [Bug 1920067] Re: Xorg with EVDI can't start with Mesa 21.0
I performed the splash -> nosplash test described above; it made no difference. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1920067 Title: Xorg with EVDI can't start with Mesa 21.0 Status in mesa package in Ubuntu: New Status in xorg-server package in Ubuntu: New Bug description: As I indicated in a bug report I filed earlier today, https://bugs.launchpad.net/ubuntu/+source/evdi/+bug/1920059, evdi-dkms can no longer compile the evdi kernel module with the 5.11 kernel. So, to work around this, I need to keep using the 5.10 kernel instead. But I can't, because when I boot with the 5.10 kernel this is what shows up in /var/log/Xorg.0.log when gdm3 tries to start up the login screen (note: I have an NVIDIA graphics card, which is why (I believe) Wayland isn't being used here): [ 857.957] (EE) modeset(G0): drmSetMaster failed: Device or resource busy [ 857.957] (EE) Fatal server error: [ 857.957] (EE) AddScreen/ScreenInit failed for gpu driver 0 -1 [ 857.957] (EE) [ 857.957] (EE) Please consult the The X.Org Foundation support at http://wiki.x.org for help.
