(Get the code!)
i confirm too.
i have a "ATI Technologies Inc Radeon XPRESS 200M 5955 (PCIE)" on a HP pavillion dv5000.
When i try the alpha 6 live cd (also present on alpha 5 and 4) I also get:
When it boots from the Hardy Live-CD's (32 or 64 bit) it will get to the point where it tries to load compiz and then fails. When it fails it kicks back to GDM, auto logs in, fails on compiz and back to GDM.
If i then try to go into tty2 to diagnose the screen mangles, the image you were currently looking at in x is left frozen on the screen, with a mild distortion on a few pixels, and the mouse is locked. In fact no futher update to the screen happen, except for a few random pixels in the top left changing a little as you switch between the tty's. In conclusion it is completely knackered.
Anyway, on the live cd boot screen, i change to just "install ubuntu" (so that ubiquity would come up, ie without compiz), and disabled the splash screen. Then when ubiquity was running doing nothing, i was able to switch to tty2 and look around (as compiz hadnt kicked in and broken everything). if i do sudo apt-get remove compiz-core then, i can get sucessfully onto the desktop, by just cancelling ubiquity and waiting for gdm to restart (well metacity isnt running, but i can just run that)
when i was on feisty and gutsy i was able to get compiz running with the official ati driver (fglrx) installed through the restricted drivers manager, and then installing xgl. so the xpress 200m shouldnt be blacklisted completely, if xgl and fglrx are running, then compiz should attempt to work
for the above poster: "Once fglrx is installed and I reboot I can log into my GNOME session no problem.", this is because fglrx is blacklisted, right?, you could equally just remove compiz.
however, i find that running compiz by hand, compiz still tries to run and breaks everything. so for me at least it looks like a simple fix of blacklisting the card (but not blacklisting with xgl)
