Ok, I just made up that term because I don't know what to call it. Running xfree on a twinhead laptop I'm getting lots of screen corruption. Thing is, the corrupted areas are always three rectangular blocks, and the contents of the blocks are miniature distorted copies of the entire screen. It's very weird. A screen-in-a-screen sort of effect, except the copies are mostly garbled. Is there a name for this sort of screen corruption? The driver is trident. Here's the /proc/pci info: VGA compatible controller: Trident Microsystems TGUI 9660/938x/968x (rev 211). This is a redhat system, with XFree 4.3. I also tried dropping in the trident driver from 4.2, which behaves the same way. About four years ago XFree worked fine on this hardware. I don't remember what release it was. 3.1.x, or something. Please CC replies to me. Thanks, b.c. _______________________________________________ XFree86 mailing list XFree86@xxxxxxxxxxx http://XFree86.Org/mailman/listinfo/xfree86
