When the computer wakes up (so when I re-log in after he went to sleep) the 2nd screen is a bit messed up. Let's try to explain that better: the content is shifted to the left, meaning that the left part of the window in the right screen is not visible and on the left part of the screen there is a black area.
One image is worth a thousand word, so here comes a screenshot of the problem:
hum, when I take a screenshot the problem is not showing, the 2nd screen looks fine. So here comes a regular foto:
so there you can see the 2 sides I am missing.
Please ask me if you need more info (and if you give me the command in order to get the info you need you'll save me some google search :)
thanx for reading
