Thread: NVIDIA AND ATI

  1. #1

    Default NVIDIA AND ATI

    i have opensuse 11.1 on a portable hard drive

    I was wondering if there was a way to put NVIDIA and ATI drivers on opensuse

    because i have one computer that has an nvidia graphics card

    and the other a ATI graphics card.

    Typically openSUSE comes with
    • Frame buffer graphic driver (not so commonly known about) and
    • Vesa graphic driver (works mostly on all graphic cards) and
    • one or more free opensource "openGL" graphic drivers (for ATI and separate for nVidia).
    openSUSE does not come packaged with proprietary drivers, although there are proprietary drivers.

    To be more specific ......

    In the case of nVidia this means:
    • fbdev - frame buffer driver (comes with openSUSE) very slow. Very limited in resolution colours. Survives a kernel/xorg update.
    • vesa - vesa driver (comes with openSUSE). Slow (not as slow as fbdev). Survives a kernel/xorg/update.
    • nv - openGL driver for nvidia (comes with openSUSE). Better performance than vesa. Survies a kernel/xorg update. Probably does not support special desktop effects.
    • nvidia - proprietary nVidia driver (go to here: NVIDIA - openSUSE ) . Best performance. Will break when there is a kernel/xorg update.


    In the case of ATI this means
    • fbdev - frame buffer driver (comes with openSUSE) very slow. Very limited in resolution colours. Survives a kernel/xorg update.
    • vesa - vesa driver (comes with openSUSE). Slow (not as slow as fbdev). Survives a kernel/xorg/update.
    • ati - openGL driver for ATI older hardware (comes with openSUSE) Better performance than vesa. Survies a kernel/xorg update. Probably does not support special desktop effects.
    • radeon - openGL driver for ATI radeon hardware (comes with openSUSE). Better performance than vesa. Survies a kernel/xorg update. Probably does not support special desktop effects.
    • radeonhd - openGL driver for ATI HD radeon hardware (comes with openSUSE). Better performance than vesa. Survies a kernel/xorg update. Probably does not support special desktop effects.
    • fglrx - proprietary ATI driver (go to here: ATI - openSUSE ) Best performance. Will break when there is a kernel/xorg update.


    Typically one will install an ATI or nVidia driver by one of two methods:
    • add the appropriate software repository (ATI or nVidia) to one's software package manager, and then install the appropriate rpms with the driver. Then boot to run level 3 and run "sax2" with appropriate arguments to configure/modify the xorg.conf file.
    • download a " .run " file that is a binary that will custom build the driver on one's PC (for ATI or nVidia as appropriate). Then configure/modify the xorg.conf file (typically via "sax2" with appropriate arguments). This is often called "the hardway" although it is NOT hard.
    Sometimes extra steps are required.

    Note kernel updates almost always break the proprietary driver. The repositories do not always have the updated driver after a kernel update, and hence typically the "hardway" of installing the ATI/nVidia driver has a better probability of working.

    @oldcpu: I read the OP and I thought they meant that they would like to be able to setup X for two different graphics card environments, depending on which computer the external drive (containing openSUSE) is plugged into. I'm not sure how this could be tackled. Maybe with 2 grub entries pointing to 2 different root file systems?

    I know recent Ubuntu and Fedora distros (using new Xorg versions), have virtually done away with xorg.conf, and use hal to detect the graphics hardware at boot and load the correct drivers.

    the VESA driver in the kernel should work for both cards.
    Else you could install both drivers, configure one xorg.conf for ATI and one for NVidia and copy them in place depending on the hardware you are using.

    ferrari was right, i have two graphics cards that are completely different one is NVIDIA the other is ATI. is there away for both of them to talk on suse? etc NVIDIA on my desktop ATI on my friends computer?

    how would i configure to xorg files?

    step by step would be great, as im a bit of a rookie

    at the momment i can use nano and terminal pretty well but its the "what to type as a command" i get mixed up.

    is there a program like Evy

    that might detect the graphics in your computer?

    for suse??

    Not aware of anything like that. I think you either accept a basic vesa driver (to cater for either graphics chipset), or try recent distro like FC11, or Ubuntu 9.04. BTW, have a read of this blog concerning 'no xorg.conf required'.

    In theory, it would be possible to write a script to detect the graphics hardware (and have it executed at boot time before X starts) and link xorg.conf to appropriate xorg file version stored somewhere, but not practical, and I'm not up for the job!

    Just had a look at Envy. Looks interesting. As a Python app it may be able to be adapted for openSUSE. Sadly no RPMs available AFAIK.
