This sounds like a regression of bug 1727356. And it appears the patch for that bug was dropped in mutter version:

And still is. -- 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/1839637 Title: Display driver missing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1839637/+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
