Comment 135 for bug 948053

Reinstalling all of my mesa packages borked my DRI:
$ LIBGL_DEBUG=verbose /usr/lib/nux/unity_support_test -p
libGL: screen 0 does not appear to be DRI2 capable
libGL: OpenDriver: trying /usr/lib/i386-linux-gnu/dri/tls/swrast_dri.so
libGL: OpenDriver: trying /usr/lib/i386-linux-gnu/dri/swrast_dri.so
libGL error: reverting to indirect rendering
OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: Quadro4 900 XGL/AGP/SSE2
OpenGL version string: 1.4 (1.5.8 NVIDIA 96.43.23)

Reinstalled 96.43.23 & got DRI (and GL vertex buffer object) back.

@Flames: PEBAC? Were you trying for PEBKAC or similar?

I realize what vdpau is used for. However:

$ apt-cache depends mplayer | grep libvdpau
  Depends: libvdpau1

@giardia: libvdpau1 error now appears on the 96.43.23 that I did. This is due to reinstalling libvdpau1 before the reintall:
$ cat /var/log/nvidia-installer.log |grep libGL
         /usr/lib/i386-linux-gnu/mesa/libGL.so.1 -> libGL.so.1.2 (File

         -> libGL.so.1 (File exists).
WARNING: Unable to restore symbolic link /usr/lib/i386-linux-gnu/libGL.so ->

Also reinstalled libvdpau1 to get mplayer working again. Thanks for tip.
