Hello everyone,
after reinstalling KDE the “AE” key doesn’t work, so I had to write AE. I have a Cherry KW 9100 SLIM keyboard and in the settings I set a Generic PC keyboard with 105 keys, which always worked.
It may also be that after cleaning the keyboard, the error occurred with a spray provided for this?
What can I do?
Buy cheaper, disposable keyboards, maybe?
Seriously, I have no suggestions.
Perhaps the key is sticking internally. 
Haha well one reason I’d pay more for a keyboard is that it should be trivial to pull off the keycaps and find out what’s sticking and what’s not…
The tool to test it would be ‘xev’ which (with wayland) is now wev - and that’ll print out a ton of stuff whenever you touch your mouse or keyboard to work out if the KEY isn’t working, or if your new settings just don’t recognise it for some reason - and I have no clue about that.
What cæn we do? You can get around it for now with Composeae
What layout are you using?
localectl
Is Æ a separate key?
If not, how do you access Æ, and is it just the Æ part that doesn’t work?
For a gb layout, æ is the third level, and Æ is the fourth level of the A key.
So to use them, I set the key to choose the third level in the keyboard settings. I use Alt Gr aka Right Alt.
System Settings → Keyboard → Keyboard → Key Bindings → Key to choose the third level
Or you can use compose as @Ben has already said. The compose key can be set here:
System Settings → Keyboard → Keyboard → Key Bindings → Position of Compose key
You can test with evtest and/or xev -event keyboard (or wev for wayland).
Thank you very much for your help!
I first connected the keyboard to another notebook. The key doesn’t work there either! Now I’ve contacted Cherry support and asked for help! I only bought this expensive keyboard in March 2024! I’ll never buy something this expensive again.
Then I tried, but …:
wev -event keyboard ✔
zsh: command not found: wev
Sounds like the key may be broken, assuming it’s a dedicated key. We still don’t know because you haven’t told us anything. I did do a search, the first one that came up was a german version but it didn’t seem to have a dedicated Æ key.
evtest, xev and wev are not installed by default. I prefer evtest for testing the key itself, it’s a layer lower than xev. I’ve never actually used wev.
sudo pacman -S wev
sudo pacman -S xorg-xev
sudo pacman -S evtest
Looking at the man page wev doesn’t accept the same options as xev, this looks like the one you’d want:
-f <interface[:event]>
Only show events for the given Wayland interface, or for a specific event from that interface. May be specified more than once to show
several interfaces and/or events.
xev may already be there,
if not xorg-xev is the package that contains it,
wev probably needs to be installed as well first before you can use it
Thanks again for your ideas! I received an answer from Cherry support and can return the keyboard under warranty!
