also FYI i helped
a guy reformat + dual boot a failing windows computer (which may still be failing; we thought it might have been motherboard issues.. results pending). It took all of maybe 2 hours cumulative. there was a lot of drinking and card playing going on the other room which we joined whenever there was a large progress bar doing its thing.
anyway ubuntu detected his bigass Sony monitor as supporting some serious widescreen resolutions which it does however the generic linux driver supplied for his Radeon 9200 did not (or maybe it's the VGA cord instead of the DVI cord that's the problem there..). So we had to hax the xorg.conf file to use 1280x1024 at least for now.
I'm not sure what might be causing you grief with installing ubuntu. one option to consider is to download the "
alternate installation CD" (scroll down a lil bit) which allows you to install in text mode. that's what we did last night only because that was the only version of 6.10
ubuntu (as opposed to ku- or xu-buntu) that i had burned to bring over to his house. it works just as well as the graphical Live CD install but it's not as pretty :)
