Comment 26 for bug 157319

I am using using Ubuntu 10.04 LTS with a dual core AMD and Nvidia Video card

desktop:~$ /usr/games/sol
Xlib: extension "RANDR" missing on display ":0.0".
The program 'sol' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 483 error_code 8 request_code 152 minor_code 5)
  (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() function.)
desktop:~$

I am using a NVIDIA card with the latest nvidia restricted driver with two screens. I so I guess I am using Xinerama

So I go run System - Preferences - Monitors and I get:
Could not get screen information
RANDR extension is not present

If I run:
desktop:~$ cat /var/log/Xorg.0.log |grep RandR
(==) RandR enabled
(==) RandR enabled
