Bug Description
On request, moved this bug report from bug 123283. Which covers very similar symptoms on ATI hardware.
Binary package hint: xserver-
Here's what happened on my laptop in Hardy:
- Xubuntu Hardy beta live CD
- Insert CD, boot to desktop
- wait several minutes with no mouse activity
- screen goes completely blank
- move mouse
- screen came back
- wait few minutes
- screen completely blank. While the screen is completely black, I can see feint detail on the screen (like the back-light is off but the screen still has stuff on it).
- move mouse. When I move the mouse the back-light comes on but the screen is black apart from the mouse pointer.
- mouse pointer appeared but screen still blank, mouse responds to movement and cursor changes when hovering over a text field for example, computer appears to respond to input (clicking etc.)
- VT switch to terminal 1
- VT switch to terminal 7
- screen came back to normal.
In Gutsy, I cannot VT switch but if I ssh into the box and temporarily start a new X server and then kill it, that restores the original screen (possibly because it causes a VT switch).

Weird. But I've seen where doing a VT switch can bring a system back to sanity.
Thanks for attaching your Xorg.0.log. It looks like your hardware is:
Intel Corporation 82830 CGC [Chipset Graphics Controller] rev 3 [chip 8086,3577 card 1179,ff00]
No other obvious errors jump out though. But the 830 is a pretty old chipset. We have seen a lot of issues with i8xx chips when using the new -intel driver, and have worked with Intel to fix a lot of them, particularly i855; it wouldn't surprise me that there is additional work to be done for the old i830.
Fwiw, we're still including the "i810" driver in Hardy since we know some old chips like yours work better with it than with intel; however we plan to deprecate i810 in Intrepid so would like to help you solve the issue so you can use "intel" going forward.
The first step is to test some newer versions of "intel". I've built a handful of git snapshots from upstream for you to try out:

Try the newest version at the top of the page, and maybe one or two other picked at random. If you find it does not solve it, then the next step would be to file this bug upstream.
