Comment 20 for bug 1307546

Michael,

You can make an xorg.conf that doesn't functionally change anything for example: http://askubuntu.com/questions/217758/how-to-make-an-xorg-conf-file

After you make the xorg.conf and put it in place, reboot to make sure the system still boots with it.

If it does, do the dist-upgrade, install the proposed package and then reboot.

If the xorg.conf remains in place then this bug is fixed. If it gets renamed, then you have hit the bug again.
