Description Sebastian Brandt 2008-10-16 11:28:09 UTC 
The GeForce 8300 graphics chip is not supported by the open source nVidia driver of the current (7.4) xorg release. 

The 8300 is only available as OEM/on board, e.g., on the ASUS M3N/H-HDMI mainboard.
lscpi: 02:00.0 VGA compatible controller: nVidia Corporation Device 0848 (rev a2)

According to http://en.wikipedia.org/wiki/GeForce_8_Series#Geforce_8300_and_8400, it has a G86 core.

NVidia proprietary driver supports it, of course (since at least 173.14.05)

Excerpt from Xorg-log with open-source nVidia:

X.Org X Server 1.5.2

(II) Primary Device is: PCI 02@00:00:0

I installed the xorg 7.4 from http://download.opensuse.org/repositories/X11:/XOrg/openSUSE_11.0/ and expected it to support more nVidia devices than the 7.3 version ... unfortunately, it doesn't.

Comment 2 Sebastian Brandt 2008-10-16 12:53:12 UTC 
Patched nv_driver.c to get the card to work w/o acceleration, at least ... though I'm not sure whether this gives any advantage over VESA ;-)

The only thing needed is to add the (masked) PCI ID of the card to the 
  static Bool
  NVIsG80(int chipType)
function in nv_driver.c:

        case 0x06f0:
//added in line 804:
        case 0x0840:
            return TRUE;

AND to set Option "NoAccel" "true" in the xorg.conf driver section.

If the NoAccel is left out, the log appears the same; the "only" difference is that the screen is half black, half patterned. 
Ctrl+Alt+Backspace does not work then, nor does console switch. Remote login, then kill -9 XOrg , then chvt works to get the system usable again. Normal kill or chvt w/o kill does not help.

This is a log which did not work ... apart from the NoAccel/XAA stuff, no obvious differences to the one before.
For the moment, I switch back to VESA, as VESA is by far faster than nVidia/OS w/o XAA ... and, for much stuff, even faster than NVidia/closed source ...

Sorry, didn't notice this was nv, not nouveau.
