After installation vboxvideo is loaded much earlier (no rootfs to unpack) and getting userspace up and running takes a few seconds, so once X is started the native driver is ready and everything works as it should.
On the live-session though, the xserver realizes a new device has arrived and loads modesetting on it (with VESA already loaded) and we get this mess. While this is a bug in the X stack, getting it fixed properly before release is unlikely, because it's a fringe case no-one else is seeing. -- 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/1796822 Title: Desktop live cd boots corrupted screen in Virtualbox on Bionic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1796822/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
