I'm having difficulties in remapping some of my keys on Ubuntu 20.04 and
gnome-control-center version 3.36.2. The problem is similar to Bug
#1867548 but manifests itself even with gnome-control-center versions
with this bug fixed.
I follow the below steps to exchange the Control_L key and XF86WakeUp key (Fn
on German keyboards):
I execute xev to discover the Control_L and XF86WakeUp keycodes:
KeyRelease event, serial 37, synthetic NO, window 0x4600001,
root 0x5dd, subw 0x0, time 4165720, (668,636), root:(902,854),
state 0x4, keycode 37 (keysym 0xffe3, Control_L), same_screen YES,
XLookupString gives 0 bytes:
XFilterEvent returns: False
KeyPress event, serial 37, synthetic NO, window 0x4600001,
root 0x5dd, subw 0x0, time 4166218, (668,636), root:(902,854),
state 0x0, keycode 151 (keysym 0x1008ff2b, XF86WakeUp), same_screen YES,
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False
Then, I run
$ xmodmap -e "keycode 37 = XF86WakeUp"
and
$ xmodmap -e "keycode 151 = Control_L"
After which xev shows:
KeyRelease event, serial 37, synthetic NO, window 0x3c00001,
root 0x5fd, subw 0x0, time 1691367, (1390,1888), root:(1584,2066),
state 0x0, keycode 151 (keysym 0xffe3, Control_L), same_screen YES,
XLookupString gives 0 bytes:
XFilterEvent returns: False
KeyPress event, serial 37, synthetic NO, window 0x3c00001,
root 0x5fd, subw 0x0, time 1692110, (1390,1888), root:(1584,2066),
state 0x0, keycode 37 (keysym 0x1008ff2b, XF86WakeUp), same_screen YES,
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False
Saving this to a .Xmodmap file and looking at the content correctly shows the
change:
$ xmodmap -pke ~./Xmodmap
$ cat ~/.Xmodmap
-- snip --
keycode 37 = XF86WakeUp NoSymbol XF86WakeUp
keycode 151 = Control_L NoSymbol Control_L
-- snip--
However, the system still treats key 37 as Control_L, and key 151 as
XF86WakeUp. Setting 'xmodmap .Xmodmap' to ~/.xinitrc and rebooting also
doesn't work.
