I am running natty. When I first installed the alpha hibernate was broken (video garbled, I'll attach a video) but I could not report the problem. Then recently (I'd say two weeks ago, so around 1st of april 2011) it was fixed by updates. However after that something bad and unrelated happened and I reinstalled from a daily live. The problem is again there as of 16th of april.
The problem is that the display is garbled, no characters are visible but what appear to be random pixel lines. It's so even in the consoles (ctrl+alt+fn).
In the attached video you can see the problem. First, I am on the locked screen after hibernate. Then I enter my password. As you can see the computer is perfectly working but video is garbled. I can click on the shutdown menu and all the rest. In the third part of the video I switch to a virual console and press enter repeatedly. What can be seen is a series of white messed-up pixels where white console text lines should be.

This also affects the eeePC 1000HE. The garbled screen goes away after putting the netbook in sleep mode for a second.
