Hi, I followed the tutorial, reinstall quite a dozen times scratchbox, but that still doesn't work... I have my Xephyr window on the good DISPLAY variable, but when I launch af-sb-init.sh start, i can see the n770 interface during a few milliseconds, and I get the following trace : Note: For remote X connections DISPLAY should contain hostname! Sample files present. Starting DBUS system bus Starting D-BUS session bus daemon Starting Maemo Launcher: maemo-launcher.

All windows have a colormap, however, pixmaps only have colormap by default if they were created with a non-NULL window argument. Otherwise a colormap must be set on them with gdk_drawable_set_colormap The program 'maemo_af_desktop' received an X Window System error. This probably reflects a bug in the program. The error was 'BadMatch'. (Details: serial 432 error_code 8 request_code 56 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.) matchbox-wm: X error warning (0xa0002b): BadWindow (opcode: 12) matchbox-wm: X error warning (0xa0002b): BadWindow (opcode: 12) matchbox-wm: X error warning (0xa0002b): BadWindow (opcode: 25) maemo-launcher: child (pid=5439) exited due to exit()=1 As I'm not an X Window expert, I really need some help. And I really followed the maemo tutorial... Thanks :)
