Occurs several times a day without an identified pattern. Began immediately after a fresh install of ubuntu precise. [Original Description] Since the precise installation the system is having problem with the video display. Sometimes there's corruption in the screen and sometimes random hangs of the X server. Usually the computer can be recovered by restarting lightgdm and rebooting afterwards. The computer is a macmini (mid 2011 model) and precise (beta 2) has been installed without using bootcamp (no BIOS emulation).

The next time we attempt to wait upon the buffer (after userspace handles the signal), we believe that the buffer is idle and so skip the wait. There are a number of bugs across all generations which show signs of an overly haste reuse of active buffers. and then you say "But that kernel already contains a backport of that patch"... :) Reply at: https://bugs.launchpad.net/xserver-xorg-video- intel/+bug/983146/comments/7 ------------------------------------------------------------------------ On 2012-04-17T19:58:54+00:00 Bryce Harrington wrote: Okay.
