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 Ubuntu-X, 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1861609/+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
