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.
