Linux DID install my SiS 630 video card, but without any support for games etc.. so i downloaded the ones off www.sis.com , its a rpm file 1.2 mb... last time i tried to install them all i did was run the rpm file and restart but it screwed up linux so i had to reinstall, i wanna try again but do i have to edit/install anything else? like the XF86Config file?
that would depend on why it screwed up... I have an SIS630 as well which has worked for as long as i can remember with the SIS driver provided with X.
(run XF86Config, when you choose your video driver it will/should be in the list)
