Thank you for your bug report, what did you upgrade? what error do you get exactly? can you run gnome-session when starting a startx session?

[cdab (cdab)]

running gdm Version: 2.27.90-0ubuntu1

i think http://ubuntuforums.org/showthread.php?t=1250057 discusses my problem, adding "Option "DRI" "0"" to my xorg.conf seems to solve my problem...

i couldn't find a bug report discussing the issue... so i filed a new one...

thanks for your help

the issue seems rather an xorg one then

Hi cdab,

Please attach the output of `lspci -vvnn` and `dmesg`, and attach your /var/log/Xorg.0.log (and maybe Xorg.0.log.old) file from after reproducing this issue. If you're using a custom /etc/X11/xorg.conf please attach that as well.
