Bug Description
On this laptop, resume from suspend to RAM barely works under Lucid, while it works flawlessly under Jaunty.
These are the most salient aberrations:
1) The display comes back in a strange pattern of random colors and characters. It looks like the display is in console mode, but the screen saver seems to be active, since if I type in my password I will later find the display unlocked.
2) To actually get to a sane display, I have found that switching between a few virtual consoles will eventually do the trick. If I did not blindly type in my password earlier on, I will now see the screen saver's password prompt.
3) When I finally get back to Gnome, I find that the desktop background has changed to an irregular black-and-white pattern.
4) After resume, the machine thinks it is running on battery, so the display is dimmed to the lowest setting, and the battery icon is displayed.
I don't find this behavior acceptable, especially since the same function used to work perfectly on the same hardware in an earlier OS version.

Attaching pm-suspend.log. Shouldn't ubuntu-bug have done that automatically?
