The Super Key does not work with i3wm when I configure it as the configured modifier key.The used configuration file is the one that is initially generated choosing the Super/Windows Key instead of Alt.xev recognises the key presses of the Super Key well enough. KeyPress event, serial 40, synthetic NO, window 0x200001,    root 0x289, subw 0x0, time 11708837, (38,142), root:(763,601),    state 0x0, keycode 133 (keysym 0xff7e, Mode_switch), same_screen YES,    XLookupString gives 0 bytes:     XmbLookupString gives 0 bytes:     XFilterEvent returns: FalseKeyRelease event, serial 40, synthetic NO, window 0x200001,    root 0x289, subw 0x0, time 11714471, (38,142), root:(763,601),    state 0x2000, keycode 133 (keysym 0xff7e, Mode_switch), same_screen YES,    XLookupString gives 0 bytes:     XFilterEvent returns: FalseSo the identifier of the Super Key is Mode_switch. I found this question which talks about a very similar problem. However, the answer did not work on my case. Using xmodmap (I know I should be using setxkbmap instead, but I couldn't find the equivalent for these commands) I did:xmodmap -e clear mod4Which worked as expected. And then:xmodmap -e add Mod4 = Mode_switchWhich returned the following error:X Error of failed request:  BadValue (integer parameter out of range for operation)  Major opcode of failed request:  118 (X_SetModifierMapping)  Value in failed request:  0x17  Serial number of failed request:  11  Current serial number in output stream:  11QUESTIONWhat is the setxkbmap equivalent answer to the question I linked?How do I avoid the error xmodmap gave me?An answer to any of these could help me get the Super Key working.
