Greetings,

we have installed Ubuntu 11.04 (64-bit) and have two monitors installed. The graphics card is nvidia quadro 4000. Two monitors (Dell 1920x1200 and Wacom 21 UX2) are running in TwinView-mode.

Now to the issue:

1st: unity didn't work, but that was not a big deal, due to the fact that we simply used gnome2

2nd: in gnome2, the left monitor (Dell) just works fine, but the wacom does not. The problem that can be observed is some kind of 'artefact', and the wacom screen is not entirely being used. On the right side we have a (smth about 7 cm) black vertical stripe, and on the bottom a horizontal artefact over the complete width (extending into the black stripe area).

Thanks in advance for any hints and
with best regards

Daniyal
