AltGr doesn't work in Linux console

Question

When I am in a console (not terminal emulator) (after using Ctrl+Alt+F_, AltGr+key combinations are not working.

I am using a Czech keyboard layout which (as many layouts do) maps various special characters to AltGr+key combinations (sometimes called dead keys, I believe). For example I can write | by typing AltGr+w (AltGr is right-Alt).

This works perfectly in DE (in my case GNOME Shell), but doesn't in a Linux console. Any advice how to fix it? The Czech layout is missing many important keys (like >) so it's kinda impossible to work in terminal. I use Fedora 25 with latest updates.

EDIT: I've just tried it on my second PC with Fedora 25 (but upgraded from F24 and still using X11 instead of Wayland) and it works correctly..

Solution 1

Solution for my problem is to run localectl --no-convert set-keymap cz.

This will change VC Keymap from cz-us-qwertz which doesn't seem to define AltGr combinations as they are shown here.

Solution 2

I had what looks like the same problem, after I switched to the Gnome desktop. But setting any of the de keymaps like in the first answer was no help. Apparently Gnome maps AltGr to Alt, and this can be changed with

gsettings set org.gnome.desktop.input-sources xkb-options "['mode_switch:ralt_rctrl']"
