I am experiencing really bad screen flickering on my second monitor in Ubuntu.
I'm not sure how to go about fixing this, it's plugged in via DVI.
If I don't do anything the screen rarely flickers (it does but it's very little and in a rhythmic pattern), but if I type or move my mouse around it flickers like crazy.
Here's the output of sudo lshw -C video

Any suggestions would be much appreciated!
