I run into this on Ubuntu Budgie 20.04 when trying to open GNOME Settings. It dumps me to to the login screen. I just tried to use About and it did the same thing. This is in a VirtualBox virtual machine if that is relevant. Happy to provide additional detail if needed. Thanks for looking into this. -- 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/1796437 Title: [nouveau] Xorg crashes with assertion failure "key->initialized" in dixGetPrivateAddr() from dixLookupPrivate() from DRI2Authenticate() Status in xorg-server package in Ubuntu: Confirmed Bug description: Went to the menu button in upper left corner.
