I guess the proprietary fglrx driver has not been completely removed. See https://help.ubuntu.com/community/RadeonDriver#head- 229f59879c2a2b6c6635d1e189706d97f836b879
Try: dpkg -l '*fglrx*' and locate fglrx to see if there is still some evil proprietary bits around. It looks like a mismatch between files that usually are provided by libgl1-mesa-glx and libgl1-mesa-dri. Try: apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri ** Changed in: xserver-xorg-video-ati (Ubuntu) Assignee: (unassigned) => Tormod Volden (tormodvolden) Status: New => Incomplete -- ati opensource driver - no direct rendering https://bugs.launchpad.net/bugs/153511 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
