Super key is logically stuck down

[Ali]

There are shortcuts like 'Super + P' to change the display mode or 'Super + l' to go to login screen. However, after i upgraded ubuntu 18.04 to 20.04, if i press P or l or any other character which there is a 'super + key' for it, it's does the same thing. It's like the super key is always on!

My keyboard works fine in Unity so it's not a hardware problem.

GNOME Shell 3.36.1
Ubuntu 20.04 LTS

I wonder if this is related to bug 1871913. Does it happen only with secondary keyboard layouts?

@vanvugt
Maybe, Because it also doesn't open activities overview on secondary layout, but is more than that.
I can't type almost anything when i switch to gnome.

[Ali (ariaman5)]

It happens for both layouts because shortcuts are the same. "L" navigates to login screen whether the input language is Persian or English because there is 'Super + L' shortcut.

[Daniel van Vugt (vanvugt)]

Sounds related. Maybe wait until bug 1871913 is fix released to focal. Then if this issue is still not fixed after that we can report it upstream.

Please run:

  gsettings list-recursively org.gnome.desktop.a11y.keyboard

and then paste the output here. I am wondering if you have "sticky keys" enabled.
