Ok. Well, thanks anyhow.
In contrast to your apparent ease of use with the NVidia driver, when I install it fresh without alteration, I get ASCII garbage upon X startup and results in a hard lockup. I know there are others out there who at least used to have this problem.
I think it might have something to do with the Ti4200 chipset. Perhaps this chipset does not support SBA?
Anyone have the solution to this?
