White desktop, no launcher icons

[Oliver R.]

After a clean install of Ubuntu 12.04 LTS from CD I experience the behavior described in bug #902670:

The main desktop area is dead white. No display of anything except the pointer cursor.

The launcher bar shows in some kind of purple, but without icons. Hovering the mouse over the launcher bar flashes 'tooltip' descriptions of what should be there. These extend over the white desktop.

The top 'tray' bar shows with its proper icons.

Pressing Alt-F2, for example, leads to a window over the white desktop area.

Immediately after logging in, I can see the correct background, but then it's immediately covered with the white block.

After deinstalling xserver-xorg-video-nouveau everything works as expected. So it seems to be a problem of the interaction of the driver with the graphics card:

01:00.0 VGA compatible controller [0300]: NVIDIA Corporation NV31 [GeForce FX 5600] [10de:0312] (rev a1) (prog-if 00 [VGA controller])

I changed the target of this bug accrodingly.

Since it's a friend's computer, I won't be able to do more testing on this.
