Hi I upgraded virtualbox to its latest version 3.1.6 and addition of guest additions works perfectly.
The version of virtualbox on which it was crashing was 3.1.4. I was running ubuntu 9, win7, opensolaris all on 3.1.4 and they were finding fine. On the changelog of virtualbox for 3.1.6, there is this note: Linux Additions: support Ubuntu 10.04 (bug #5737) see: http://www.virtualbox.org/wiki/Changelog -- Ubuntu 10.04 graphics crash when run as guest in VirtualBox https://bugs.launchpad.net/bugs/562739 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
