Hi Colin,

The Compiz opengl plugin is not loading, which is obvious:)  So I've
been thinking about why it's not loading on your machine.  The "old
hardware" in the bug title got me wondering what type of graphics
hardware is in the system.  I just now noticed that you wrote that you
have Intel 865 graphics.  After looking at
http://en.wikipedia.org/wiki/Comparison_of_Intel_graphics_processing_units,
this is Intel 2nd generation graphics and supports OpenGL 1.3.

Compiz/Unity require OpenGL 1.4 and above in order to work.  The
crapping out of the opengl plugin is not very friendly, but this is what
is happening.  I think you said that you tried forcing llvmpipe, but
that didn't work, so I'm not really sure what you can do at this point.

For confirmation, try issuing /usr/lib/nux/unity_support_test -p and see
what it says.

Title:
  Unity fails to load on old hardware on Saucy

Status in “unity” package in Ubuntu:
  Confirmed

Bug description:
  On logging in I see just the wallpaper with no top panel and no launcher.
  Note that this is not bug #1066764 (Unity fails to load on old hardware (compiz enabling LLVMpipe has no effect and Mesa tries to use hardware still)) as compiz is at 1:0.9.9~daily13.04.18.1~13.04-0ubuntu4 and the errors for that bug are not seen in .xsessionerrors.

  .xsessionerrors only contains
  Script for cjkv started at run_im.
  Script for default started at run_im.

  The graphics is an intel 865 chipset.
