I've got a problem when booting:
I see the GRUB screen where I can choose what exactly to boot into - after hitting Enter my screen simply shows me that purplish background and after some seconds it shows me the Ubuntu logo with the logo dots in a pretty low resolution (my guess would be 640x480); it then loads quickly and takes me to the login screen. So it's working, just not quite right I guess.
My computer is a Lenovo Thinkpad x121e, with a AMD e350 CPU and an ATI Mobility Radeon HD 6310 graphics card (fully detected and working with the vesa:wrestler
drivers).
