--- Begin Message ---Package: xserver-xorg-video-i810 Version: 1:1.5.1.0-2 Severity: important Since I upgraded my Toshiba Libretto U105 to use the new xserver-xorg from unstable, Xorg will shift the graphical display contents by about 25 lines downwards and 768 pixels rightwards, wrapping lines around. The result is not quite usable. All in all that's 32768 pixels, at 4 bytes per pixel, a 128KiB offset. This upper section of the screen is originally filled with contents of the previous VT, and slowly being filled by regular patterns, about 26 pixels at a time, about one burst per second. In the X log, I see notably: (--) PCI:*(0:2:0) Intel Corporation 82852/855GM Integrated Graphics Device rev 2, Mem @ 0xd8000000/27, 0xd0000000/19, I/O @ 0xeff8/3 (--) PCI: (0:2:1) Intel Corporation 82852/855GM Integrated Graphics Device rev 2, Mem @ 0x20000000/27, 0x2a000000/19 ...

In any case, this ring buffer allocation seems to me as being premature and causing the bug. I haven't kept logs from previous working versions of the server; if the information may help you, I'll send it when I have successfully downgraded my xserver (ouch, a whole lot of stuff needs to be co-downgraded).

It would be great if > you could check upstream whether it's fixed in current xf86-video-intel The new version of the i810 X.org driver in Debian since August seems to fix these problems. It's the first version since the X.org 6.8.2 package in Debian which is able to display an ungarbled desktop on my system or doesn't crash immediately on server start.
