So I just installed Ubuntu 12.10 from the Windows installer (dual-boot). Ubuntu seems to boot fine until it gets to the login screen. There are small graphical glitches in the screen and whenever I move the mouse, it becomes even worse (I can barely see anything on the screen). I run it on a mini-laptop with AMD Athlon 64 processor and ATI Radeon graphics. It seems to be a problem with my drivers, but I am really new to Ubuntu and Linux and I can't find how to solve my problem (I know very little about the terminal since I used cygwin for SSH communications with a server). It is not connected to internet (I have a wifi, but I can't get Ubuntu to connect to it).

UPDATE: Considering they have pretty much killed Wubi now I recommend getting Ubuntu on a DVD or a USB Stick and trying out the 'LiveCD' version on them (for the most recent 13.04). – Ads20000 Apr 27 '13 at 6:37

I had the same thing until I installed the 13.2 beta drivers.
