[mythtv-users] OpenGL makes mythfrontend crash !!

[Franco]

I've noticed that if I set "OpenGL transitions"
in mythgallery, as well as "glgears" as a myththmusic visualization,
mythfrontend immediately crashes.

Note that OpenGL works fine with my Nvidia MX 440, I can 
play chromium with full graphcs details at 50 fps.

Also, I'm constantly upgrading myth with apt-get
since version 0.14 but the above problem was always present.

What's the trick to tell myth to use OpenGL?

Thanks,
Franco
