that vboxvideo has been dropped upstream, I also tried an rm on my zesty vm of that file but it didn't change the boot issue.
I don't understand your modeset sentence, because actually I don't understand what vboxvideo does (kernel module) what the driver is supposed to do, and what/how that vbox*GL* libs can replace the vboxvideo_drv I mostly do what upstream does here: https://anonscm.debian.org/cgit/pkg-virtualbox/virtualbox.git/tree/src/VBox/Additions/linux/installer/vboxadd.sh#n223 but there is one difference, installing the guest additions works, the my approach worked in Debian and works in Debian, and worked in Ubuntu before zesty. Zesty changed something I can't understand (and breaks only my build, not the upstream install script) -- 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/1666059 Title: Main virtualbox window resizes itself 3 or 4 times - then no desktop start To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1666059/+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
