I'm not sure which graphics card i'm using!! because When i ran lspci -v | less, i'm getting following output: 00:02.0 VGA compatible controller: Intel Corporation Eaglelake Integrated Graphics Controller (rev 03) (prog-if 00 [VGA controller]) Subsystem: Intel Corporation Unknown device 1003 Flags: bus master, fast devsel, latency 0, IRQ 11 Memory at fe400000 (64-bit, non-prefetchable) [size=4M] Memory at d0000000 (64-bit, prefetchable) [size=256M] I/O ports at f1c0 [size=8] Capabilities: <access denied> I'm using ubuntu 8.04. I ran the nvidia-xconfig from command line. and got the below output. Also attaching my xorg.conf file. I tried with several combinations of xorg.conf but unsuccessful. How to add the Configured Video Device?. Do we need to install any drivers for this?.
