sorry form my english but is not my mother tongue, I hope I can explain me

I have problem with gnome 3.10, I put "exec gnome-session" in the file .xinitrc but when I launch startx, I have a crash (black screen).
When I try to lauch gdm, with "/etc/init.d/xdm start" I have no error but nothing appear.

I can put some output if you need, let me know

Check /var/log/messages (on OpenRC) or the output of the command `journalctl -rb` (on systemd) for details.

I think I found the problem, in my kernel there is no systemd option and I don't started dbus, now it works (with some problems but gnome start)

what now I can't do is change the keyboard layout, when I launch gnome-control-center and I choose regional settings I have this error

Code:
(gnome-control-center:2877): GnomeDesktop-WARNING **: Could not read list of available locales from libc, guessing possible locales from available translations, but list may be incomplete!

(gnome-control-center:2877): region-cc-panel-WARNING **: Failed to contact localed: Error calling StartServiceByName for org.freedesktop.locale1: GDBus.Error:org.freedesktop.DBus.Error.Spawn.ChildExited: Launch helper exited with unknown return code 1

Segmentation fault
localhost ~ # gnome-control-center

thanks a lot

See https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces on how to debug segmentation faults. In short, add -ggdb to CFLAGS and rebuild the package; then enable core dumps. Next time you try, it will write a core dump; then you can open it in gdb (see "Starting gdb on a core file") after which you can capture the output of `thread apply all bt full` to see where it faults. If you get question marks, functions or code paths that are unclear; you'll want to rebuild the libraries involved in the backtrace(s) too.

The output of these backtraces can then be used to pinpoint the problem in the code; using that, we can either fix it ourselves or send it upstream such that upstream can look into it.

thanks, I'll try to do so!

one more question, I hope the last :wink: I don't understand why the setting of the keyboar layout in the xorg.conf is ignored

Code:
Section "InputDevice"
        Identifier      "keyboard0"
        Option          "XkbLayout" "fr_CH"
        Driver          "kbd"
EndSection


but I tried also so
Code:

Section "InputDevice"
        Identifier      "keyboard0"
        Option          "XkbLayout" "ch"
        Option           "XkbVariant" "fr"
        Driver          "kbd"
EndSection



thanks

You might be able to see why in /var/log/Xorg.0.log; maybe the Identifier doesn't match, or the Option has an incorrect syntax.

my xorg.conf

Code:
#
# X.Org server configuration file generated by Parallels Guest Tools.
#

# Parallels Video section
Section "Device"
   Identifier   "Parallels Video"
   Driver   "prlvideo"
EndSection

# Parallels Monitor section
Section "Monitor"
   Identifier   "Parallels Monitor"
   VendorName   "Parallels Inc."
   ModelName   "Parallels Monitor"
EndSection

# Parallels Screen section
Section "Screen"
   Identifier   "Parallels Screen"
   Device   "Parallels Video"
   Monitor   "Parallels Monitor"
   Option   "NoMTRR"
   SubSection   "Display"
      Depth   24
      Modes   "1920x1440" "1024x768" "800x600" "640x480"
   EndSubSection
EndSection

# DefaultFlags section
#Section "ServerFlags"
#   Option   "AllowEmptyInput"   "yes"
#   Option   "AutoAddDevices"   "yes"
#EndSection

Section "InputDevice"
   Identifier   "keyboard0"
   Option      "XkbLayout" "ch"
   Option      "XkbVariant" "fr"
   Driver      "kbd"
EndSection

# DefaultLayout section
Section "ServerLayout"
   Identifier   "DefaultLayout"
   Screen   "Parallels Screen"
   InputDevice   "keyboard0"
EndSection



I tried with some keyboard layout but notning change, it is like there is another file that overwrite my xorg.conf
