Comment 22 for bug 560306

Same problem. I have tried:

- 'nomodeset' and 'radeon.modeset=0', and many combinations of 'noapic', 'nolapic', 'noacpi' kernel options.
- Ubuntu and Kubuntu Beta 2 live cds, and the Kubuntu Beta2 Alternate CD (all 64bit).
- Failsafe graphic mode from boot menu (fails and returns to boot menu)
- installing the ATI proprietary driver from the recovery console
- 'apt-get update/upgrading' to the latest packages from recovery console.

In any combination of the above that I've tried, it's always the same behaviour: brief splash screen followed by blank screen.

I would be happy with the most basic non-DRI 2D right now, but I can't even get that working as xorg.conf and 'dpkg-reconfigure xserver-xorg' seem to be deprecated (replaced with what I don't know?) and 'X -configure' doesn't work either.

Hardware:
- ATI Radeon HD5850
- Asus P5B Deluxe motherboard
- Intel Core2 Quad
- 4Gb RAM
