Re: [Discuss-gnuradio] grc - libGL error: failed to load driver: i965

[Andreas Ladanyi]

I think i solved the problem with the slow windows a little. The reason was the armsoc driver of the X Server. This driver was configured in the xorg.conf. There was another file named xorg.conf.mali which contains parameter to use the mali driver.

I renamed the both xorg files so the file with the mali driver could be load instead of the armsoc driver. The reaction of all windows / textboxes / sliders are better. This problem was not only with the gnuradio guis instead it was a general problem.

The libgl error is always present.

Hi,

 

when i want to start a grc project i get the error message: libGL error: failed to load driver: i965

 

Iam working on odroid (MALI 400 GPU) 3 with Ubuntu 14 and i start the grc via ssh and X-Forwarding on my PC.

 

The grc project i want to start and run on the odroid works great and the cpu load is about 50 % on all 4 cores. But the wx gui graphs and sliders etc. are very slow / not responding. The editing operations in the grc editor GUI are also slow (but thats no problem for me because iam developing on a pc).

 

I read that this could be a problem with the mali graphical driver and the OpenGL/OpenGLES but iam not familar with the details and how to fix them for gnuradio.

 

Could you give me help, please ?

 

cheers,

Andy
