Upgrading Ubuntu to the latest beta version proved to be a bad idea.  The X server wouldn’t load after the upgrade and its becasue my video card (for some reason) gives it trouble.  I tried manually editing the xorg.conf file but nothing worked.

And another odd thing, the distribution only works in the safe graphics mode for the 32-bit version.  The 64-bit AMD ISO doesn’t work in either normal or safe graphics mode.  The built-in drivers for my ATI X850 card are pretty slow.  Upgrading them helps but after I do, the GL screensavers don’t work.

Anyone out there with an X850 from ATI have similar problems with Ubuntu?
