@juhuu, can you please attach the output of "tail --lines=5000 /var/log/dpkg.log"?
Also, can you uninstall only the 3.1 update and see if that issue goes away again? If you havn't cleaned out your apt cache the corresponding old DEBs should still be on your machines so you can uninstall using: sudo dpkg -i /var/cache/apt/archives/*mesa*0ubuntu3_*.deb Then logout and login again and see if the issue is gone? If it goes away, can you then install the patch again (and double check) using: sudo dpkg -i /var/cache/apt/archives/*mesa*0ubuntu3.1_*.deb (not entirely sure but that _should_ work I guess) -- Kubuntu freezes when desktop effects are enabled https://bugs.launchpad.net/bugs/351990 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
