    I do have that glx line in there; maybe I tried the games a couple driver
    versions back, and at the time they didn't work so I didn't try again.

    Here's glxinfo as me:

    Error: Could not open /dev/nvidiactl because the permissions
    are too resticitive. Please see the FREQUENTLY ASKED QUESTIONS
    section of /usr/share/doc/NVIDIA_GLX-1.0/README for steps
    to correct.

    (/dev/nvidiactl was owned by root.root, mode 0600)

    Whoops, fixed by making /dev/nvidia* mode 0666 permanently, as described
    in that document. I would prefer to have them 0600 owned by the user
    running X, but since >1 user can run X on the console simultaneously that
    won't work.

        GLX_ARB_get_proc_address, GLX_ARB_multisample, GLX_EXT_visual_info,
        GLX_EXT_visual_rating, GLX_EXT_import_context, GLX_SGI_video_sync,
        GLX_NV_swap_group, GLX_SGIX_fbconfig, GLX_SGIX_pbuffer,
        GLX_SGI_swap_control, GLX_NV_float_buffer
    GLX extensions:
        GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_SGIX_fbconfig,
        GLX_SGIX_pbuffer, GLX_SGI_video_sync, GLX_SGI_swap_control,
        GLX_ARB_get_proc_address
    OpenGL vendor string: NVIDIA Corporation

    /proc/driver/nvidia/version contains:

    NVRM version: NVIDIA Linux x86 NVIDIA Kernel Module 1.0-6106 Wed Jun 23 08:14:01 PDT 2004
    GCC version: gcc version 3.2 20020903 (Red Hat Linux 8.0 3.2-7)

    glxgears doesn't seem to be any faster since I fixed PAM (it still uses
    100% CPU). Do I need to restart X?

                 Unix is user-friendly; it's just picky
                    about who it makes friends with.
