I am seeing this as well. I'm actually hosting the VM in VMware workstation 12.5, but the scripts install both VMware and virtualbox guest tools (so that an OVA is useful in both).
I have an older snapshot that does not have problems, which is using 5.0.40-dfsg-0ubuntu1.16.04.2. The OVA I built today, where X crashes on startup, got 5.1.34-dfsg-0ubuntu1.16.04.2. From https://launchpad.net/ubuntu/+source/virtualbox/+publishinghistory, I don't see any versions between that built for xenial to narrow it down further. Uninstalling virtualbox-guest-x11 makes the problem go away; X11 works again, at least in VMware. Presumably it would now not work in VirtualBox. It seems to be happening because virtualbox-guest-x11 is stealing the alternatives for x86_64-linux-gnu_gl_conf and x86_64-linux-gnu_egl_conf, even though it's GL libraries won't work *at all* on another host. 5.0.40-dfsg-0ubuntu1.16.04.2 doesn't seem to have alternatives for these, much less high-priority defaults for them. -- 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: 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
