Note to others: On my 7.0 light, /sbin/vxkbset is quitting with message "Cannot find X11 keymap list", though it's there.
Not enough time to chase it down tonight. But I wonder if this couldn't account for some reported install problems, also.
Later: Added a temporary dump to build_menu_modelx. Returns STATE=2, so it's not finding "! model".
Still later: It looks like bash no longer does [[ =~ ]] . Changed the first one to just "! model" and the exit changed to STATE=1.
@PaulR: It's supposed to be done by /sbin/vxkbset, which can be accessed by start > system > vasm, choose super > XWINDOW > XKBSET, but that's not working. Until this fuddle is corrected (or someone tells me how silly and wrong I am when I'm tired),
put "setxkbmap gb" in gdm's startup script.(see below)
I'm too tired to locate gdm's startup script, hopefully someone will point it out or suggest a better place.
There's also a way to put just this change in xorg.conf.d , but I haven't figured that out yet.
Seriously, I should sleep:
If you have /etc/X11/xorg.conf.d/90-keyboard-layout.conf , as root edit 'Option "XkbLayout" "us"' to 'Option "XkbLayout" "gb"' . If the file's not there,
cp /usr/share/X11/xorg.conf.d/90-keyboard-layout.conf /etc/X11/xorg.conf.d/ then edit. Restart X, or use the "setxkbmap gb" command directly to change it for the current session and let the system pick up the change from xorg.conf.d at next reboot.
