Bug Description
After installing Lucid, Alpha 3, I noticed when I was using x-chat, gmail, gwibber, empathy, or switching between chromium tabs - that I would be able to move my mouse, but if I clicked on anything nothing happened. I could not change desktops, applications nor could I reboot or shut down up my Dell M1330. I would have to do a hard reboot in order for the mouse to work.

We have a return of the i915.powersave breaking graphics particularly when suspending and resuming. It seems that this only affects i945 and below so we will try and turn this off for those cards only to start with.

My system hangs very often and seems to be related to hibernation or power down on no use. I leave the system and come back and it's hung. There are a few ways it hangs i.e. when overly busy but often when doing nothing for long periods.
A hang today with a Sysrq dump shows (I think) i915 as the pid farther with as the trace getting a 120 second timeout at __mutex_
I'm running Ubuntu 9.10 with all updates as of 4-12-2010. This happened on 10.04 LTS also.
I have a few traces with mem and blocked from sysrq if anyone would want to look at them.

For me, this bug has not, repeat NOT, been solved.
I use a Toshiba A80 laptop with a i915 graphic card. My Ubuntu experience with it is not too good...
- Jaunty: faulty driver release, after some weeks, I downgraded to driver 2.4
- Karmic: computer can't be used for suspend to RAM during the full time of this release, i.e. six months
- Lucid: the same (one week).
I have now the normal kernel 2.6.32.22.23 and, after resume, I always experience a freeze between 10 minutes to 40 minutes. Sometimes, I am informed that I must switch to low resolution mode, sometimes it's just a black screen...
I've upgraded to kernel 2.6.33.3 but I've the same result.
This bug has NOT been solved. Thanks for help.
