Comment 39 for bug 156824

As with some of the other posters in the downstream Launchpad bug:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/156824

I am experiencing a jittery mouse and unresponsive system for a number of seconds (5 - 10 seconds) after opening my laptop lid.

I am seeing this behavior under:
Ubuntu 8.04 Hardy Heron
Ubuntu 8.10 Intrepid Alpha 5
Fedora 9

Note that I am usually running Ubuntu 8.04 Hardy on this machine currently.

In fact on Ubuntu 8.04 the behavior is more severe - the icons on the desktop flash four or five times during the 10 second period and if I have desktop effects disabled (and am therefore using metacity I assume) all the application windows flash on and off also!

Under Fedora 9 and Ubuntu 8.10 Alpha 5 the more tame but frustrating effect reported by the other posters is seen - the system and mouse are "jittery" and only partially responsive for around 5 to 10 seconds after opening the lid.

During the period after opening the lid "top" shows Xorg is using 40-48% of CPU.

My system is a Dell Inspiron 9400 with Intel Core Duo T2300 at 1.66GHz (from cpuinfo).
The graphics card is Intel 945GM (from dmesg output).

Please tell me what I can do to help diagnose this issue. I have spare partitions on this machine that I can use to install other distros if that it helpful (ie to test other versions of xorg).
