[mythtv-users] [mythtv] If you're using an override to choose the Qt painter in master...

Taking to the -users list, since I think this might require a lot of 
discussion...

Ingwer, looking at your mythfrontend output, it seems there may be a big 
problem with your driver installation.  Specifically, it's very 
suspicious that there's no information provided for:

2012-01-31 20:29:26.017001 I [4032/4032] CoreContext mythrender_opengl2es.h:118 (InitFeatures) - OpenGL: Vendor  :
2012-01-31 20:29:26.017026 I [4032/4032] CoreContext mythrender_opengl2es.h:120 (InitFeatures) - OpenGL: Renderer:
2012-01-31 20:29:26.017035 I [4032/4032] CoreContext mythrender_opengl2es.h:122 (InitFeatures) - OpenGL: Version :

TTBOMK, nvidia's drivers will--even on Quadro--provide at minimum a 
vendor name (though I'd expect them to provide vendor/renderer/version, 
as they do with nvidia's non-enterprise GPU line).  You should be seeing 
something like:


OpenGL vendor  : NVIDIA Corporation
OpenGL renderer: GeForce GT 220/PCI/SSE2
OpenGL version : 3.3.0 NVIDIA 290.10

though with information for your card in the renderer.

Can you try re-installing the nvidia drivers, please.  At first, feel 
free to force a reinstall of the opensuse package.  I hope that will fix 
the issues for you.  If not, there are some other things we can try, but 
they get a bit uglier.

That said, if we determine that this is caused by a driver installation 
problem, I can likely fall back to the Qt painter if all of 
vendor/renderer/version are empty, so this may be a good indicator 
you've reported.  I would like, however, to get yours working properly 
(since the card/drivers /should/ be able to do OpenGL painter without 
any issues--and without any strain at all on the GPU, actually).

Thanks,
Mike
