Version: 2:1.9.5-1
I have experienced the same problem. I'm using Xephyr since yesterday and it's the first time it happens. I don't know if it is easily reproducible.
The way I'm using Xephyr is as follows
(this has been the only way to get my german keyboard configured properly):
1. Open Xephyr:
Xephyr -keybd ephyr,,,xkbmodel=evdev,xkblayout=de -ac -reset -screen 1672x1022 -retro :10 &
2. Store xmodmap and launch a new terminal in Xephyr:
xmodmap -pke > /tmp/my_modmap ; DISPLAY=:10 nohup terminator -e "xmodmap /tmp/my_modmap; bash" &
(* for details about terminator, see footer of this message)
3. Start a gnome-session in the terminal opened in 2.:
gnome-session
I'm using a USB keyboard attached to the notebook where the session is hosted. In Xephyr I'm launching a gnome-session.
I have tried to fix the problem unsuccessfully resetting the keyboard according to
https://experts.missouristate.edu/display/csvhelpdesk/Reset+Keyboard+Map
I also have tried to fix the problem (also unsuccessfully) changing:
o Keyboard model (from Generic/Evdev-managed to Generic/Generic 105-key)
o Keyboard layout
o "Keyboard Layout Options"/"CapsLock key behavior" with the "Keyboard Indicator 2.28.0 applet for GNOME."
The keyboard works properly after closing the gnome-session and the x-terminal opened in 2, and reopening a new x-terminal.
Greetings,
Alberto
