Bug Description
Binary package hint: xserver-
This was a Ubuntu 8.04 fresh install on Viglen Dossier LX. Every few hours, apparently randomly, everything freezes apart from the mouse pointer. Ctrl-Alt-F1 or Ctrl-Alt-Del does nothing, but I can ping the laptop. Typically this occurs when scrolling up or down in Firefox using touchpad or keyboard, and there is some screen corruption at the bottom of the scroll bar (as if a blit failed or was interrupted?).
The symptoms aren't quite the same as bug #36596, bug #248438: it does seem closest to bug #184430 which was attributed to a faulty adapter, but again doesn't sound identical, nor to (Debian bug) #459428 which sounded unresolved. No visual effects, because it claims they are not available; before the hang I can switch to a console. I've tried Option "RenderAccel" "off" and Option "AGPMode" "2" for "Configured Video Device" but neither seems to help, nor reducing AGP aperture in BIOS.
Xorg.0.log shows the uninformative:
mieqEnequeue: out-of-order valuator event; dropping.
tossed event which came in late

Does this happen with a release later than hardy, have you ever tried?
