Thanks Steve. Your log file confirms it is this bug:
May 27 11:37:42 lurcher /usr/lib/gdm3/gdm-x-session[2452]: Xorg: ../../../../../../include/privates.h:121: dixGetPrivateAddr: Assertion `key->initialized' failed. And the workaround of removing gstreamer1.0-vaapi was also discussed in bug 1796437 and bug 1745345. But the fact that any package can crash Xorg is still a Xorg bug, not a bug in that other package. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1861609 Title: [focal] Xorg crashed with assertion failure (usually in a VM) at [privates.h:121: dixGetPrivateAddr: Assertion `key->initialized' failed] and call stack comes from DRIMoveBuffersHelper Status in xorg-server package in Ubuntu: Confirmed Bug description: Xorg crashed with assertion failure (usually in a VM): privates.h:121: dixGetPrivateAddr: Assertion `key->initialized' failed. and call stack comes from DRIMoveBuffersHelper WORKAROUND Select 'Ubuntu on Wayland' on the login screen.
