I upgraded to lucid again to get some tracebacks and logs for the errors
so if I have a few to show. Most programs are crashing with the same
error after installing the ppa with the UI enhancements. 

Gdk-ERROR **: The program 'totem' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 1067 error_code 8 request_code 1 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error()
Trace/breakpoint trap

Thats the main error im getting at the moment. If someone could tell me
what else to look for id be happy to give some more info.
