  • Disable direct rendering for a specific application

    Posted on

    I need to disable direct rendering for an application launched from the 7.5 desktop terminal. I have tried using:

    $ LIBGL_ALWAYS_SOFTWARE=1 (application name)

    But this does not set it to use software rendering.

    Below is glxinfo from the ssh session which works:
    name of display: localhost:10.0
    display: localhost:10 screen: 0
    direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose)
    server glx vendor string: Open Text

    and desktop terminal session which does not:
    name of display: :11.0
    display: :11 screen: 0
    direct rendering: Yes
    server glx vendor string: SGI

    Ideally I would like this to be set globally.
