How enthusiastic I was about Ubuntu in my last post :-)
Ubuntu gradually white-screened more and more on reboot, shutting down and starting up ......
Now I cannot even boot off the installer CDs !!
I tried resetting the PRAM.
I tried what is suggests in yaboot.
I have a non-standard video card in the Cube, but it obviously works and I can't see Ubuntu caring what was originally in a machine as old and obscure as this.
I am disappointed now :_(
