[Bug 574947] [NEW] Secondary Monitor flickers after upgrade then stops working..

[Paven]

Public bug reported:

After upgrade to 10.4 my screen flickered (i was using a LG Flatron 19)
the display settings gave the wrong name(goldstar) so i asumed it was
bug https://bugs.launchpad.net/bugs/546083. But it wasn't.

This bug has a posible relation to "Secondary monitor does not work on ATI HD5770"
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/550407
since the displays now stooped working and i have an ATi graphics card on my T60

During my testing i have tested on the folowing monitors
 2 difrent LG Flatron 19, 1 sammsung. 1 lenovo
and on 1 Lenovo TV
one projektor

The secondary display worked perfectly until i rebooted my computer at
the end of the lucid(10.4) install.

I plan to test booting another os/installation to rule out that hardware
has been broken.( but don't have the time right now)
