Bug remains with 2.6.38-10.46 kernel.

[Chris Van Hoof (vanhoof)]

Hi Tim -- Fixes in this area are presently in the current natty -proposed kernel (2.6.38-11), can you install this kernel, and give this another test to confirm the issue still exists?

[Ara Pulido (ara)]

Waiting on Tim's reply

[TienFu Chen (ctf)]

Sorry for the delay, bug remains with proposed kernel 2.6.38-11.47

[Anthony Wong (anthonywong)]

From the screenshot, it is the same problem as 790824, so marking this bug as a duplicate of 790824.

Tested on Asus 1215P on the latest 11.04 image (/w 2.6.38-12 kernel package) and legacy Gnome desktop (no 3D desktop effects) , external display worked properly.
