Sorry, I have to take that back (a little): it worked in VMware and in VirtualBox, but I just realized VirtualBox hadn't set the 3d acceleration option when it imported the OVA. So your code (correctly) didn't turn on the OpenGL redirects. If I turn on the 3d acceleration, then it enables /etc/ld.so.conf.d/00vboxvideo.conf, and then graphics are broken in virtualbox (same symptoms as before, lightdm crashes).
This turned out to be because my very stripped-down image was preseeded using d-i base-installer/kernel/image string linux-virtual to avoid getting lots of irrelevant drivers and firmware (stripped a few hundred megs off the OVA). But unlike linux-image-generic, linux-image-virtual doesn't depend on linux-image-extra, which means I didn't have vboxvideo.ko. Installing virtualbox-guest-dkms fixed this by providing the missing kernel drivers. But that suggests the test for enabling /etc/ld.so.conf.d/00vboxvideo.conf isn't quite thorough enough, though this is probably a bug that should go upstream for VBoxClient --check3d instead of adding more to your script. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1762491 Title: [SRU] No graphics after update, caused by virtualbox To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1762491/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
