retitle 590534 gdm3: changes xkb options thanks Hello,
I was affected by the same bug, so I tried to find out what was wrong.
I am using no GNOME stuff, not even a gnome-settings-daemon, except
gdm3 to log in. I have no /etc/X11/xorg.conf, and in my
/etc/default/keyboard, I have:
XKBOPTIONS="compose:menu,terminate:ctrl_alt_bksp"
This gets exported correctly by udev:
% grep XKB /dev/.udev/db/input:event*
/dev/.udev/db/input:event0:E:XKBOPTIONS=compose:menu,terminate:ctrl_alt_bksp
When I start a session with startx, I get the expected keyboard setup:
% setxkbmap -print
xkb_keymap {
xkb_keycodes { include "evdev+aliases(azerty)" };
xkb_types { include "complete" };
xkb_compat { include "complete" };
xkb_symbols { include
"pc+fr(oss)+inet(evdev)+compose(menu)+terminate(ctrl_alt_bksp)" };
xkb_geometry { include "pc(pc105)" };
};
But when I start my session with gdm3, the options compose(menu)
and terminate(ctrl_alt_bksp) disappear:
% setxkbmap -print
xkb_keymap {
xkb_keycodes { include "evdev+aliases(azerty)" };
xkb_types { include "complete" };
xkb_compat { include "complete" };
xkb_symbols { include "pc+fr(oss)+inet(evdev)" };
xkb_geometry { include "pc(pc105)" };
};
So it looks like gdm3 is:
* interpreting what it can from udev or xkb configuration: geometry and
layout;
* discarding the remaining: compose(menu) and terminate(ctrl_alt_bksp);
* overriding the xkb configuration with what it could understand;
* not setting the initial xkb configuration back after login.
I think the appropriate behaviour for a display manager should be not to
touch to the keyboard configuration at all, unless explicitely told to
do so.
