Secondary Monitor flickers after upgrade then stops working..

[Paven]

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)

Hi Paven,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
