Binary package hint: xorg

Lucid beta 1 fails to boot on my Apple iMac 27" (Core i5 model).

I am happily running Karmic (had to download backport Alsa to get sound working), but Lucid beta 1 fails to boot. You initially see the new purple Ubuntu loader, then it goes black - CD continues to whirl and after it sounds like it is loading in the background it resets and restarts.

Suspect problem with video - I can get it to boot if I select option F6 and "selectnomodes" (I think thats what it was called) - it boots fine (I am running it now).

Question: Would this stop me upgrading from Karmic?

If you need any more info, please email.
