I have a laptop of which a large part of the screen is broken (shows garbage). Fortunately the broken area is a clean rectangle, the bottom 1/3 of the screen or so.
The laptop is running Ubuntu 8.04, but I plan to reinstall it with 10.10. The graphics are provided by an Intel 915GM or something in that direction.
Knowing this, do you know of a way to tell the system about the broken part of the screen, so it will simply not use it? I don't really care whether it's done at the hardware, X or window manager level, though as low as possible is preferred.
