I have this Asus UL30VT notebook, with two video cards, an Nvidia G210M (which apparently isn't supported by Nvidia for Linux, but I've read somewhere that it's possible to make it work) and an Intel card (I can't find the model name). On Windows, it is possible to switch between these two cards for battery saving reasons. Anyway, I don't really care about this on Linux. I would just like to make the Nvidia card work somehow.
One of my doubts is: how do I know if Linux is detecting both video cards? Both cards are listed by lspci:
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
01:00.0 VGA compatible controller: nVidia Corporation Device 0a74 (rev a2)
and I'm quite sure Linux is currently using the Intel card, because I have no xorg.conf file, and the X log says:
(II) LoadModule: "intel"
(II) Loading /usr/lib/xorg/modules/drivers/intel_drv.so
(II) Module intel: vendor="X.Org Foundation"
compiled for 1.7.6, module version = 2.11.0
Module class: X.Org Video Driver
ABI class: X.Org Video Driver, version 6.0
What I'd like to know is, how can I make sure whether Linux is correctly detecting the Nvidia card or not? Is lspci enough?
And if we suppose that Linux is aware of the presence of the Nvidia card, how do I know which card it's using? Right now I can infer it's using the Intel card from the X log, but is there any other way (I don't know, any "/proc/..." files) to know?
I'm sorry if the post is a bit confusing, but I'm confused as well :-)
