I have this same problem with a 1440x900 lcd monitor. at 1440x900 it is offset to the right by about 1.5 inches. at 1280x720, its just fine. > > I called xvidtune, which promptly said that my video wasn't tunable.

(I > restarted X after each change.) same problem. for some reason the intel drivers (I'm using sid so its xserver-xorg-video-intel instead of -i810) will not let you do this. Basically, it seems that X won't let you do anything that it doesn't already want to do. I played around with modelines for long time with absolutely zero effect. I think my monitor is reporting the wrong information such that xorg won't let me set it properly. meh. > > I have not tried installing the i810 driver from Intel.

Thanks. nope, but I'm happy to try ideas and help work on it a bit. A
