Bonjour, Gnome applications like gnome-terminal and xscreensavers seem to be unable to work with two screen and xinerama enabled. (FC6) Here are the errors messages: The program 'gnome-terminal' received an X Window System error. This probably reflects a bug in the program. The error was 'BadValue (integer parameter out of range for operation)'. (Details: serial 136 error_code 2 request_code 78 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() function.) (running with --sync option changes nothing to the message) The program 'gnome-screensaver' received an X Window System error. This probably reflects a bug in the program. The error was 'BadColor (invalid Colormap parameter)'. (Details: serial 244 error_code 12 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() function.) It used to work under FC4..... (And you are testing FC7! What fun!)
