    v32 v33  
    5353* How do I use mmap with different users?
    5454Please see the {{{--mmap-group}}} option: the two users need to be in the same group, the mmap file created by the client will use the group-id of the server socket file. You must generally also use the {{{--socket-dir}}} option to place the socket in a location which is available to both users (ie: {{{/tmp}}})
    55 * How do I enable {{{OpenGL}}} or other X11 extensions on the server?
    56 Please see [/wiki/Xdummy Xdummy], for acceleration see [http://www.virtualgl.org/ virtualgl]
    5755* How do I theme my application?
    5856That depends on the application. GTK2 applications can be themed by setting the  GTK2_RC_FILES environment variable, ie:
     
    6866* "{{{Message: pygobject_register_sinkfunc is deprecated (GstObject)}}}"
    6967This harmless warning comes from your distribution's python-gstreamer build, sadly it cannot be avoided.
    70 * "{{{No OpenGL_accelerate module loaded}}}"
    71 You can safely ignore this warning, it only means that some {{{OpenGL}}} operations won't be accelerated.
    7268* "{{{Xlib: extension "RANDR" missing on display}}}" and "{{{Randr not supported: X server does not support required extension Randr}}}"
    7369The virtual framebuffer (typically Xvfb) does not support Randr, this may cause some display problems, try using [/wiki/Xdummy Xdummy] instead
     
    9591The key had expired. Try re-importing the [http://xpra.org/gpg.asc updated key].
    9692On Debian you may have to delete the key ({{{apt-key -d}}}) before adding it again.
    97 * I get some {{{OpenGL}}} related warnings or errors:
     93* During installation I see warnings like these:
     94{{{
     95chcon: can't apply partial context to unlabeled file
     96}}}
     97If you have disabled {{{SELinux}}} you can ignore those warnings, otherwise you may need to relabel your filesystem and ensure that the xpra codecs mentioned in those warnings are labelled correctly to prevent runtime codec failures: {{{chcon -t texrel_shlib_t CODECFILE}}}

     103* How do I enable {{{OpenGL}}} or other X11 extensions on the server?

     105* "{{{No OpenGL_accelerate module loaded}}}"
     106You can safely ignore this warning, it only means that some {{{OpenGL}}} operations won't be accelerated. Or you can install the required module: {{{OpenGL_accelerate}}}
     107* I get some {{{OpenGL}}} related warnings/errors at runtime:
    98108{{{
    99109ImportError: cannot import name GL
     
    117127import OpenGL; from OpenGL.GL import GL_VERSION, GL_EXTENSIONS;'
    118128}}}
    119 * During installation I see warnings like these:
    120 {{{
    121 chcon: can't apply partial context to unlabeled file
    122 }}}
    123 If you have disabled {{{SELinux}}} you can ignore those warnings, otherwise you may need to relabel your filesystem and ensure that the xpra codecs mentioned in those warnings are labelled correctly to prevent runtime codec failures: {{{chcon -t texrel_shlib_t CODECFILE}}}
