The xev output for both left alt and right alt is given below. I could not use right alt for any purpose due to this. What could be the problem? Thanks in advance.

Open System Settings, Keyboard, Key Bindings (top right button), turn off “Key to choose the 3rd level -> Right Alt”
it was all disabled for me. So now i enabled it and choose the option “Right alt never chooses the third level” and now it works. What actually is the third, second and fifth levels? And why is it enabled even if the entire setting to choose 3rd level key is disabled?
Anyway this solved my issue but still curious on what thoose levels in keyboard are
What keyboard layout are you using? It might be set as default there. Those extra levels change the keys on your keyboard to produce extra symbols, like shift+a produces A, shift3+a might produce å (as it does on my keyboard layout).
OOOOh so thats what it is for… How could i see different levels and assigned keys?
Also I dont exactly know what keyboard layout i am using. It’s my laptop’s keyboard, with two hp specific keys, numpad, and no menu button or pause break button; if that helps
In keyboard settings, you can look at a preview of the layout you have configured. It’s in the menu on the right of each keyboard entry in the list.
By default there was no layout enabled in that option but can add new ones. Anyway thanks for the tips
Yes, it depends on the layout. For example, I use the “English (Macintosh)” variant of the US layout. It has bindings for level 3 shift on all keys pretty much.
I also now set it to macintosh variant. But can I assign it to right shift instead of alt? I need the alt but there seems to be no option for using shift
It doesn’t seem to be available as part of the standard modifiers. You can probably have it as part of a custom layout, but I have no idea about how to do that.
As far as I understand those selectors work, using
shift
as the level 3 modifier is a bad idea since …SHIFT
+ keyL3
+ keySHIFT
+L3
+ keyL5
+ keyL5
+SHIFT
+ keyI suppose customizing the keyboard layout such that
SHIFT
can be used as L3 modifier can be done. Otherwise, you might want to refer to/usr/share/X11/xkb/rules/evdev.lst
