    10.10 can nvidia, ati and intel opengl drivers co-exist ?

    I am using DRBL and have clients with intel, ati and nvidia cards capable of doing opengl and composite desktops.

    Unfortunately when installing ati or nvidia proprietary drivers they overwrite key libraries /usr/~~/libgl* that prevent most (if not all) opengl acceleration for the other drivers.

    Currently I can only have a single glx driver enabled (it seems).

    Ideally I would be able to install both ati & nvidia drivers and have all 3 (intel comes preinstalled) working side by side, so if I swapped cards or booted a different client the drivers would be available.

    Im currently using 10.10, but if this has been solved in later releases Id be happy to swap.

    edit: I just did some more research, could this be a possible solution ?

    backup libgl* from a fresh install, copy to /intel
    install ati drivers
    install nvidia drivers like this:
    cd /root/NVIDIA-Linux-x86-270.41.06/kernel/
    make install
    cd /root/NVIDIA-Linux-x86-270.41.06/
    ./nvidia-installer  --no-kernel-module --accept-license --no-backup  --no-x-check --no-questions --ui=none --no-x-check --no-distro-scripts --utility-prefix=/nvidia --installer-prefix=/nvidia --opengl-prefix=/nvidia --x-prefix=/nvidia/X11R6
    then do a big linux no no and use: LD_LIBRARY_PATH

    /lib/ --library-path /nvidia/lib EXECUTABLE
    Id use bash then launch xinit or launch xinit directly. To late to try now (dont want to break the media pc before going to bed) but I will try tomorrow and report back. If anyone has some suggestions Im keen to try those as well.

    Re: 10.10 can nvidia, ati and intel opengl drivers co-exist ?

    well I had partial success, my idea in the above post did not work but I had some success adding the paths to /etc/

    I can redirect the nvidia drivers to /usr/nvidia. Then add /usr/nvidia/lib to /etc/ and have the nvidia drivers work (after running ldconfig).

    This worked on machine A with a nvidia card.

    ati on the other hand offers no redirection (that I can find), I have tried manually extracting the debs files:
    dpkg-deb -c /var/cache/apt/archives/fglrx_2%3a8.801-0ubuntu1~xup~maverick_i386.deb

    and placing the contents of package:/usr/lib into /usr/ati/lib. I then added /usr/ati/lib to /etc/ but it still fails to load the glx libs, it actually seems to be trying to load nvidia libs still, though the xorg.conf is generated by the ati tool:
    aticonfig --initial -f --resolution=0,1024x768

    This failed on Machine B with a ati card.

    output of attempted x start:

    Is it possible to install ati drivers into a different location without it modifying /usr/lib symlinks ?
