Comment 4 for bug 490516

You write
It seams strange that an underlying drive issue would impact Mint but not the other apps.
It does but it's never the less well known that a driver issue can have such consequences
The pdf document which I did not look at before, because I had to close a bunch of bug reports we missed last year, does not show mintMenu but some blue fields representing mintMenu which makes it a bit hard to visualize exactly what happens
I think I see that it's only a small portion that is on the wrong display
I'm actually impressed that you got side by side single screen with Intel - I and others fail to fix that - we get just a black screen - stacking vertically is fine, but not horizontal
If you used some trick to get a horizontal single screen could you post the solution in the forum and a link here
How you did it might have something to do with your problem
