I was installing Mandriva-Linux-2005 Limited Edition and everything ran perfectly well, but my video system did't work. In Windows Taskmanager it is shown as VIA/S3G UniChrome Pro IGD, but Mandriva tries to put S3G UniChrome driver, but testing gives this mistake:

(EE) Failed to load module "/usr/X11R6/lib/modules/extensions/libglx.a" (once-only module, 136033795)
(WW) via: No matching Device section for instance (BusID PCI: 1:0:0) found

What should I do to make it find my video card? Should I download and install drivers manually. But it seems like there are no drivers for this very card for linux. And how can I install drivers form shell?
Thanks for answers
