Description Ragnar Thomsen 2015-03-09 10:35:37 UTC 
The OpenGL module of KInfoCenter will not open in Plasma 5.2.1. KInfoCenter freezes when attempting to open the module and the mouse cursor shows loading indefinitely. This occurs with both Mesa 10.4.x and 10.5.0. 

The following console output is generated when I click the OpenGL module:
Error: glXMakeCurrent failed
Comment 1 Ragnar Thomsen 2015-03-09 10:40:20 UTC 
I have an Intel Sandy Bridge integrated graphics chip and use v.2.99.917 of the driver.
Comment 2 Hrvoje Senjan 2015-03-10 02:08:44 UTC 
i can confirm this with kinfocenter master and:
OpenGL renderer string: Gallium 0.4 on AMD RV635
OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.6.0-devel
OpenGL core profile shading language version string: 3.30
Comment 3 ali.sherif10 2015-03-11 22:02:29 UTC 
Distribution: Kubuntu 15.04 beta 1.
I confirm it. I've the same bug. If I click Graphical Information then OpenGL, it loads forever. I also got the same error.
Error: glXMakeCurrent failed

It freezes.
Comment 5 ali.sherif10 2015-03-11 22:11:49 UTC 
I've switchable graphics (Intel & AMD).
Comment 6 Ragnar Thomsen 2015-04-17 09:31:45 UTC 
Still occurs with plasma 5.2.95 and mesa 10.5.3.
Comment 7 ali.sherif10 2015-04-24 11:24:03 UTC 
It exists in Kubuntu 15.04 stable version.
Make it confirmed. It affects many people.

Comment 12 Ragnar Thomsen 2015-06-03 11:03:07 UTC 
Still happens with Plasma 5.3.1 and Mesa 10.5.6.
Comment 13 Martin Flöser 2015-06-03 14:23:37 UTC 
The problem seems to be related to creating an indirect rendering context. If I remove that from the code it works.

Remove querying the indirect rendering context

Mesa fails to make an indirect rendering context current and freezes
in the next X11 call.

Removing indirect rendering support seems like a workaround for the
problem, but realisticly it's no longer interesting what indirect
rendering provides if direct rendering is available. If direct
rendering is not available, it will pick indirect instead.
