Comment 23 for bug 969489

Same issue 01-06-12 fully updated system (gnome remix based on ubuntu)
Hardware HP ProBook Sandybridge I3
Intel 3000
Intel SSD
Boottime 8 sec.

sometimes (one out of ten) the xserver freezes at login

adding 'and stopped udevtrigger to lightdm.conf fixes the issue.

 lightdm.conf looks now like this:

start on ((filesystem
           and runlevel [!06]
           and started dbus
           and stopped udevtrigger #this line I added
           and (drm-device-added card0 PRIMARY_DEVICE_FOR_DISPLAY=1
                or stopped udev-fallback-graphics))
          or runlevel PREVLEVEL=S)

Best regards,

Otto Meijer
