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.

| 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!

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  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: | #

EndSubSection
EndSection
# DefaultFlags section
#Section "ServerFlags"

# Option "AutoAddDevices" "yes"
#EndSection
Section "InputDevice"
Identifier "keyboard0"

Driver "kbd"
EndSection
# DefaultLayout section
Section "ServerLayout"

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