Today somehow my Super key is disabled. I can't use it, neither the laptop keyboard nor external keyboard. When I press the Super key, it does not send the Super key signal to ubuntu (18.04 LTS). Somehow it changed.

I checked the Super key by xev command. Here is the output:

KeyRelease event, serial 37, synthetic NO, window 0x3400001,
root 0x176, subw 0x0, time 4735544, (559,365), root:(661,519),
state 0x2010, keycode 133 (keysym 0xfe08, ISO_Next_Group), same_screen YES,
XLookupString gives 0 bytes: 
XFilterEvent returns: False

I have some key binding with Super key. I use keyboard shortcut for changing writing language, opening dash, changing window/application etc.

Please tell me how to enable the key.


The problem seems to occur after every shutdown. There might be an application which is overriding the key. Instead of running the command every time, I have figured out another simple way. See the updated answer.

I've looked into this thread and ran

xmodmap -e "keycode 133 = Super_L"

which solved my problem.


The problem seems to occur after every restart (shutdown). I couldn't figure out why this happens. To prevent this, I added the following command in startup application:

xmodmap -e "keycode 133 = Super_L"

Apparently, this is the only known solution to me.

    @TRiG, Sorry, Askubuntu won't let me accept it before two days. I'll do it later. Jul 26, 2018 at 18:36

For my case I was using the Alt key and 12 on HP Victus. But I clicked on Fn+F12 which locks the Windows/Super key since it was a gaming laptop which has such features enabled, i.e. you can lock the Windows/Super key to avoid accidental clicks on it. Clicking Fn+F12 unlocked it.
