This may not be the right section, but I can't seem to be able to post in the BT3 section so I'll post here. I've installed BT3 to my USB stick and when booting up I choose KDE (I've tried flux too however), and after everything's printed and it's all ready, the screen flickers and I hear the startup sound however the screen just goes black with colours dotted around.

It's not too easy to explain however I think you'll understand what I mean.

I've had problems like this with BT2 too, I'm using GeForce 7200GS card and LG 37LF65 TV (through RGB/VGA not DVI). Any ideas?
