gnome and xinerama



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!)

Here is my xorg.conf:
