How to know which video card is being used on a notebook with two cards?
Hello!
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: Code:
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) Code:
(II) LoadModule: "intel" 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 :-) Thanks! |
lspci is enough.
the X log file is your best bet. I'd try a bare bones xorg.conf of just this: Code:
Section "Device" |
You heard wrong...
The Nvidia G210M is listed as supported. http://www.nvidia.com/object/linux-d...35-driver.html Open the Supported Products link. You can use the command "lshw" to see what hardware information is available to linux and thereby identify your Intel chip, and "lsmod" to see what modules are being loaded for the graphics, that is, either a module for Intel or for Nvidia(nv). http://linux.die.net/man/1/lshw http://linux.die.net/man/8/lsmod |
You were right... I had probably read out-of-date information. Anyway, I managed to make the Nvidia card work. I've also found out a way to check whether the Intel or Nvidia card is enabled (only one of them works at a time in Linux, according to some BIOS SATA settings), that is by checking lspci: if the Nvidia card is enabled, the Intel card isn't even listed; so this allowed me to write a script that modifies the xorg.conf file and some other GUI-related files according to the driver in use.
Anyway, thanks to everyone for your help! |
