I have searched far and wide, yet I am confronted in GNOME on 19.04 with the fact that I cannot get umlauts etc to work. I have 2 kali (KDE) machines, on which I can get it to work quite easily. However, in this case, under Settings - devices - typing column - to find the "compose" key - is not there... I've edited etc/default/console-setup to include XKBOPTIONS="compose:Shift+AltGr" but I am sort of afraid to reboot, in fear that I might break something. Also it does not seem like the correct way since setting this functionality has been standard on previous versions of ubuntu etc.
This question has been asked many times, and has been solved many times, which is how I solved the umlaut problem on Kali/KDE too (since I am quite new on linux). Have tried linux many times in the past but only now it sticks. Any problems I have had up to now I have been able to solve without asking but this one is beyond me.
Am going to reboot now anyway, I guess I will have to.
If I don't return shortly, something broke. Otherwise, I'll be back soon ;-)
Thanks!
returned, system did not break aaannndd.... trying... e No joy. Pressing the AltGr key just shows the firefox menu bar.
I'm lost.
