cheese fails to start with the following error
I am at a loss. please help
(cheese:6633): Gdk-WARNING **: The program 'cheese' received an X Window System error.
This probably reflects a bug in the program.
The error was 'GLXBadContext'.
(Details: serial 153 error_code 169 request_code 153 minor_code 6)
(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 GDK_SYNCHRONIZE environment
variable to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
