I am all new to Ubuntu (and Linux in general) and I am experiencing some strange graphic on my screen.

Console #1 (ctrl+alt+f1):

Exactly the same happens on all the other consoles (2-6), and the consoles don't seem to work. And I see the same when I hibernate or shut down my computer, but not when I suspend it.

I was thinking that it may have something to do with the SiS 671 video driver work around that I use?

Any ideas how to fix this?

Perhaps I should add that I can simply exit the console (alt+f7) from where I can use the computer normally. – Mark A. Dec 1 '11 at 6:31
Did you try the ppa in the forums link you gave ? – bodhi.zazen Feb 27 '12 at 17:56

Try using the ppa from the above forums link

sudo add-apt-repository ppa:acasagrande/xf86-video-sismedia
sudo apt-get update
sudo apt-get install xserver-xorg-video-sismedia

Then reboot.
