Bad video behavior on resume from suspend on intel i945GM

Bug Description

When I resume from a suspend-to-ram, the screen flickers then 'bleeds'-
I get vertical streaks against a dark background that brightens as time passes.
The streaks appear to be stronger at the bottom than the top, giving the
illusion that it's bleeding from the bottom up.

This continues (doesn't get brighter after a point) until I hit CTRL-ALT-F1,
at which time the screen blanks. If I then hit CTRL-ALT-F7, the screen
wakes up (resumes the desktop) properly, and the system works
correctly from then on.

This happens most of the time that I try suspending. On some rare occasions
(~1% of the time) the system won't recover from a suspend at all, and just
hangs until I power off.

I have a Dell Latitude D620 Latitude with an intel I945GM video controller.
I'm running the intel driver from the 2:2.1.1-0ubuntu9 package.

When it exhibits the bleeding symptom, blank the screen as soon as possible, this condition isn't great for the LCD.

can you please attach your /var/log/Xorg.0.log and /etc/X11/xorg.conf and the output of lscpi -vvnn? I'd also love to get a screenshot or photo of the screen showing the 'bleeds'.

Here you go. I can't attach multiple files to one response as far as I know, so I've split this up.

And lastly, while I can't take an xscreenshot of it, I can take a picture of it and attach that.

The Hardy Heron Alpha series is currently under development and contains an updated version of the -intel driver. You can download and try the new Hardy Heron Alpha release from http://cdimage.ubuntu.com/releases/hardy/ . You should be able to test the new -intel driver using the LiveCD. If you can, please verify if this bug still exists or not and report back your results. General information regarding the release can also be found here: http://www.ubuntu.com/testing/ .
Thanks.

I don't seem to be able to change the driver under the LiveCD. Is it possible to test out Hardy's intel driver from Gutsy?

The -intel driver is used per default since Gutsy so you don't need to change it. Just boot the LiveCD and test the suspend/resume.

OK - I wasn't aware that the intel driver is the default. I fired up the LiveCD, and was able to suspend/recover with no problems six, seven, 10 times in a row, I guess - looked great!

Now is there a way to use the hardy's intel driver on my gutsy system, or do I have to wait for hardy? I'm daring and cutting edge and all, but I don't think I can run an alpha system!

Thanks for testing. As far as I know it is not possible to back port the Hardy Intel driver since it needs a newer Xorg version but Hardy will be released in around a month so it should be no problem. I am closing this bug as "Fix released". Feel free to open it again if it still happens with current Hardy.
