Error message

NVP: Timed out waiting for free video buffers

Error occurs when trying to watch live television. Error can be intermittent. Menu navigation is usually reliable. Error is usually reproduceable by trying to change channels.

Cause

This is likely caused by a conflict between the nvidia and glx drivers


Verification

Check your xorg.conf (/etc/X11/xorg.conf on Fedora Core). Under the modules section is glx listed? Under the video card are you using the nvidia driver?


Resolution

There are two ways to resolve the issue. You can either disable glx in xorg.conf and turn off the glx effects in mythfrontend or you can use the nv driver which reportedly plays nicer with glx. My solution was to turn off glx. Follow these steps to turn off glx:

  1. Launch mythfrontend
  2. In Setup, turn off all glx and OpenGL effects
  3. Quit mythfrontend
  4. Edit xorg.conf by commenting out or removing the glx driver
  5. Restart your xserver
  6. Launch mythfrontend
