View Full Version : [ubuntu] Graphics problems on an older Dell - horizontal band of graphics "gunk."

Hi all. I've got an old SC420 (Celeron) with Intel Integrated Graphics and 2 GB of RAM. I'm running Ubuntu 8.10 on it, and it's hooked up to a large Dell flat screen 2407WFP. It's connected using a standard VGA cable. About two inches from the bottom of the screen, there's a quarter-inch band of "graphics gunk" -- just where the display is distorted and pixelated.

Right now, in GNOME and XCFE (my main environment), it stays steady as long as there's no window moving over it. Once I drag a window across it, however, the window becomes distorted where the window passed over the band - lots of artifacts and such. Window Composting in XCFE is turned off. If I'm running Open Office Spreadsheet and it's maximised and I scroll through the sheet, the artifacts corrupt the entire display.

Any suggestions as to what I do to get rid of this? It's awfully annoying... Just to reiterate, the same thing and same symptoms happen in GNOME.

Thanks in advance.

Addendum:

For what it's worth, there's no distortion of the mouse pointer when it moves over the bad area -- which makes me think this is some sort of window composting-type of error?
