 Hello,

 following the "locket" Ticket #8699

 I have exactly the same problem with an ATI, NVIDIA and Intel graphic
 card, with Kunbutu QT 4.7 (rev 4.7.0~rc1+git20100917). with Kubuntu QT
 4.6.2 + NVIDIA and exactly the same trunk version (26410) this problem do
 not exist.
 It seems that the problem is related to the way QT 4.7 handle openGl
 (which is different from QT 4.6?).
 It seems that MythTv is not able to find the openGl information when
 needed for "OpenGL painter" (glxinfo gives all the correct open
 information).

 From mythfrontend:
