[Problem]
Iiyama monitor's native resolution does not display properly.

[Original Description]
After upgrading to Karmic Koala (9.10), my iiyama ProLite E2407HDS monitor does not display properly at its native resolution of 1920x1080 (16:9). It is auto-detected correctly, but at native res, the screen is black besides the toolbars, and some apps display when run, but others do not - for instance Firefox is entirely blank. The display is only usable at the lower 16:9 resolution of 1280x720. (Background and apps all display properly in this lower res.)

When scrolling through all possible resolutions, the majority of the resolutions tested did not display properly. I also checked this page:
https://wiki.ubuntu.com/X/Troubleshooting/Resolution
and was unable to solve the problem. In particular, adding kernel parameter modeset=0 did not do anything, so I cannot say whether Karmic is missing a quirk for this monitor or not.

The display worked fine at its native res (1920x1080) in Jaunty Jackalope.

If your driver has 66b194a78c470cb3978f310828dd96c3f3e96944, make sure to pull in 2a6eeec72d6bb04a32225883f431c1d2e8cff123 as well.  If not, can you attach a working log from the older driver?

Nevermind this is only relevant for atom cards and this one is not atom-based.

Does:
Option "DisplayPriority" "HIGH"
in the device section of your config file help?
Comment 8 Emmanuel Touzery 2009-11-09 07:11:12 UTC 
It reminds me on bug #24074 and bug #24406 which I'm seeing also on r200 hardware.
I think it's worth to try turning off the 3d desktop effects (compiz) to check whether it's the same problem or not.
Comment 9 Emmanuel Touzery 2009-11-09 07:14:22 UTC 
Well I checked the ubuntu bug and sure enough, in the comments:

"- Changed Visual Effects to "None." My background and icons appeared!"

Which means it's a duplicate of one of those two bugs.
Comment 10 Emmanuel Touzery 2009-11-10 03:57:44 UTC 
The reporter in the ubuntu bug agreed that this is likely a duplicate, marking the bug as duplicate.
