[mythtv-users] MythTV with Geforce 8800

[Dave]

Try removing the "GLX" extension from xorg.conf.  I have this problem 
intermittently with the new nvidia drivers too, GLX disabling was the 
only way to fix it, it has something to do with this:

X Error: BadMatch (invalid parameter attributes) 8
  Major opcode:  140
  Minor opcode:  14
  Resource id:  0x197

If you use xdpyinfo and find out what Major opcode 140 is, (its an 
extension of some sorts), that will tell you what extension causes the 
problem, for me it was GLX.
