Custom Layout Setting does not survive reboot

Hi,

recently, my custom layout settings do not seem to stick after a reboot.

Previously, I created a symbols file in my home directory, which I then symlinked to a file in the directory /usr/share/X11/xkb/symbols/. Then I added this to the layouts in the keyboard system settings and moved it to the first place. This worked up until a few days ago.

If I look at the selected layout with setxkbmap -print -verbose 10 it shows me the second layout.

My /etc/X11/xorg.conf.d/00-keyboard.conf looks like this:

# Written by systemd-localed(8), read by systemd-localed and Xorg. It's
# probably wise not to edit this file manually. Use localectl(1) to
# update this file.
Section "InputClass"
        Identifier "system-keyboard"
        MatchIsKeyboard "on"
        Option "XkbLayout" "custom"
EndSection

Is there any solution, such that my layout stays permanent.
