A workaround is possible : enable 3D support in settings/display/enable 3D acceleration (VirtualBox interface)
In this case, the vboxvideo_dri.so driver is used instead of the vboxvideo_drv.so driver (which is missing). For me, it works on all my VMs Compare file list for packages (vboxvideo_drv.so missing in xenial-updates): https://packages.ubuntu.com/xenial/amd64/virtualbox-guest-x11/filelist https://packages.ubuntu.com/xenial-updates/amd64/virtualbox-guest-x11/filelist In the update, vboxvideo_drv.so is missing. Why ??? In debian/rules for update, there is a comment : # debian/$(uxname)/usr/lib/xorg/modules/drivers/vboxvideo_drv.so Why this change has been introduced? ** Summary changed: - Xorg doesn't start after update on VMs + Xorg doesn't start after update on VMs - vboxvideo_drv.so missing -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1759452 Title: Xorg doesn't start after update on VMs - vboxvideo_drv.so missing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1759452/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
