I have a custom key mapping in the file ~/.Xmodmap which can be activated by running xmodmap ~/.Xmodmap.

However, I want this to happen automatically when I login. I have tried the following without success:

• 
  ~/.xinitrc with content xmodmap ~/.Xmodmap, as suggested here
  


• 
  ~/.xsession with content xmodmap ~/.Xmodmap, as suggested here
  


• 
  ~/.xsessionrc with content xmodmap ~/.Xmodmap, as suggested here
  

Obviously something is going wrong, but what? And how can I fix this?

Apparently for gnome it should be ~/.xprofile, but that file is executed too early for xmodmap to work.

So I got it to work by creating .config/autostart/xmodmap.desktop

[Desktop Entry]
Type=Application
Exec=/home/tvbox/bin/modmap
Hidden=false
X-GNOME-Autostart-enabled=true
Name=xmodmap
Comment=xmodmap script

And in /home/tvbox/bin/modmap, I have:

xmodmap ~/.Xmodmap

I tried the solution found here but somehow it didn't work. After a few days searching and experimenting, finally I found the culprit, i.e. Wayland.

My system is Ubuntu 18.10 and I used to log in per default. However recently I changed to Ubuntu on Wayland at login manager and since then my ~/.Xmodmap stopped working.

As I read on other sites, Wayland uses xkb instead of xmodmap. However it's still cumbersome to configure xkb. So for an average user like me the temporary solution is to switch back to Ubuntu at login screen. I hope this help other people who experience similar issue.

~/.xinitrc with content xmodmap ~/.Xmodmap works in Ubuntu 18.04. Just try rebooting your system and see if it works.

EDIT

I noticed that when I boot the Ubuntu my custom keymaps work but when I lock the screen and log back in, it stops to work. I'm trying to figure out the workarounds.
