Unrecognized deviceID 0x412 (gnome-shell:4625): Gdk-WARNING **: The program 'gnome-shell' received an X Window System error. This probably reflects a bug in the program. The error was 'GLXBadContext'. (Details: serial 137 error_code 171 request_code 154 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.)
