Comment:

If you want to run opengl applications in xpra, see wiki/Usage/OpenGL.

Installing python-gtkglext1 and python-opengl is only needed for client-side opengl accelerated rendering: wiki/ClientRendering/OpenGL.

It looks like your application (whatever it is), is having problems running against Xvfb. You may have better luck running with wiki/Xdummy - though that's often problematic to setup on Ubuntu.

  • Ticket #1363 – Description

    initial v2  
    11I've invoked the Xpra server as follows:
    2 
     2{{{
    33xpra start :5455 --bind-tcp=0.0.0.0:5555 --sharing=yes --speaker=yes --html=on --no-daemon
    4 
     4}}}
    55When I run a graphical process inside the Xpra client, I get the following errors (the graphics loads in the browser, but it works poorly and slowly):
    6 
     6{{{
    77user@host: DISPLAY=:5455 ./script.sh
    88X Error: BadValue (integer parameter out of range for operation) 2
     
    2222QSslSocket: cannot resolve SSLv2_client_method
    2323QSslSocket: cannot resolve SSLv2_server_method
    24 
     24}}}
    2525I think the GL errors make up a large part of the rendering problem. I've added the following flags to the Xvfb invocation (inside xpra/scripts/config.py on line 69) so the final invocation looks like the following:
    26 
     26{{{
    2727['Xvfb-for-Xpra-:5455', '+extension', 'Composite', '+extension', 'GLX', '+extension', 'RANDR', '+extension', 'RENDER', '-screen', '0', '5760x2560x24+32', '-nolisten', 'tcp', '-noreset', '-auth', '/home/ubuntu/.Xauthority', ':5455']
    28 
     28}}}
    2929I've also installed python-gtkglext1 as well as python-opengl Ubuntu Linux packages in an attempt to get the QGLTempContext to go away, but no such luck.
