It looks to me (checking out other similar posts on kubuntu forums) as if this is related to newer hardware and old distrubtion (8.10). Are you hooked up to a newish high-def monitor / TV by any chance?
Well I've had it a few years now, but 1080p probably counts as newish, right?
Couldn't find a solution on the web, most people seemed to use an older monitor to do the install and then hack the DPI settings afterwards. Is that an option for you?
I can certainly do that, I have an old 1024x768 I used to test the hardware beforehand. I thought it might be smoother to install in the final config rather than change it post-install. Looks like I was wrong there!
Otherwise, have you thought of trying 10.04 if your hardware is newer? It's nice ;-)
Well, it's a newish TV, but the box itself is pretty old, so I dunno. And isn't 10.04 still pre-alpha? I think I'd rather wait until it goes beta, really.
Sorry I can't be of more help...
It's cool, I can use another monitor like you said, was just checking if there was a way to fix it directly.
EDIT: Oh, this is just too much! It's pretty funny, actually. Using a monitor this time, and now the text is
enormous, and... only showing in the title bar at the top, apparently? The window contents is all grey. I don't suppose there's a decent text-mode installer instead of this GUI crap, huh? That would be too convenient...
