I have a laptop that has a damaged screen. The 24 pixels (approximately) on the right side of the screen are damaged (this is definitely not a driver problem, it is physical damage). It is not a straight bar, but rather a lot of black pixels that ebb and flow with some multicolored pixels around the edges. I got this from someone so don't know the root cause: possibly water damage?

Anyway, the "power menu as well as any scroll bars (when applications are full screen) are hidden behind this damaged area. Is there a way I can adjust the screen resolution or dimension so that these right side 24 pixels are not used? So, the laptop is 1024 x 768. Can I modify so that it is 1000 x 768 (and the 1000 are the leftmost 1000 pixels, not centered?)?

I was able to try using "xrandr" to force the screen to be 1000 wide, but then it is still centered, so it still only ignores 12 pixels on the right.

Thanks for any help. This is with Ubuntu 11.10.
