Thread: Solution to nvidia quadro 420

    Default Solution to nvidia quadro 420

    Hi All. This is not a question, but is a solution/bug that I felt was a bit tricky to work out, so I am posting it here

    I installed opensuse 11.3 (x86_64) as a fresh install. I then added the nvidia proprietary drivers as described here:

    SDB:NVIDIA drivers - openSUSE

    This caused direct rendering to fail as a normal user, but work as root. This caused 3D applications to perform poorly or not at all. "glxinfo | head" reports that direct rendering is OK for root, but not for my user.

    I had a play with strace, and found that they were opening two different libGLs:


    For root it used one in
    /usr/X11R6/lib64

    and as a normal user, one in
    /usr/lib64

    So I then unlinked the libGL.so.1 in /usr/lib64 (this was a symlink to libGL.so.1.2

    and pointed this as the /usr/X11R6/lib64 version

    And now it all works. I have no idea what the tecnical correctness is, as I don't really care -- works for me

    That took quite some time to discover, so I thought I would post this here if anyone else finds it on google, or thinks this should be a bug report or somesuch.

    Default Re: Solution to nvidia quadro 420

    Ugh. Just found out that ldconfig will undo your good works, so next time you install anything this will breka.

    Solution 2 is to modify your LD_LIBRARY_PATH to put /usr/X11R6/lib64 at the front in your .bashrc (this works for terminal launched programs....)

    run:
    gedit ~/.bashrc

    add

    export LD_LIBRARY_PATH=/usr/X11R6/lib64:$LD_LIBRARY_PATH
