setting up my keyboards (wip)
i used to be a mac user and apple keyboards are mostly the same as pc keyboards except the placement of the alt key. i’ve gotten very used to having the alt key there and since i am a linux user, i had made use of the command key as the super key and made it my mod4 key. also, i make the caps lock key a control key. so, when i got a new keyboard, i had to make things the way i like them.
starting with the linux console, i had to figure out how to make the caps lock key a control key before i went insane. also, it would be nice to have the alt key (which is actually the super key, but i swapped the pieces) function as well. this was actually really easy.
--- us.map +++ my-kbd.map @@ -49,6 +49,7 @@ keycode 56 = Alt keycode 57 = space control keycode 57 = nul -keycode 58 = Caps_Lock +keycode 58 = Control keycode 86 = less greater bar keycode 97 = Control +keycode 125 = Alt
where i got into trouble was trying to figure out how to make the alt
key behave like a super and make the super key behave like an alt key in
x11. i already had some Xmodmap rules in place to make the caps lock key
a control key, they are in a file that is called when x11 starts with a
!! make caps lock a control key remove Lock = Caps_Lock keysym Caps_Lock = Control_L add Control = Control_L !! make right alt a multi key keycode 108 = Multi_key
then to get the alt and super keys switched, i found that the file
/usr/share/X11/xkb/keycodes/evdev was the file read, so i just made
the change there
--- evdev-backup +++ evdev @@ -65,13 +65,14 @@ <AB10> = 61; <RTSH> = 62; - <LALT> = 64; + // Swapped LALT and LWIN on keyboard, so need to change codes + <LALT> = 133; <LCTL> = 37; <SPCE> = 65; <RCTL> = 105; <RALT> = 108; // Microsoft keyboard extra keys - <LWIN> = 133; + <LWIN> = 64; <RWIN> = 134; <COMP> = 135; alias <MENU> = <COMP>;
since this file is automatically loaded for my keyboard, i didn’t have
to add anything to my
xorg.conf which was convenient.
for the linux console, using
this really simple to find the codes needed.
in x11, using
xmodmap -pke to get a dump of the keys worked
actually figuring out i needed to change
/usr/share/X11/xkb/keycodes/evdev was the result of a few greps
looking for where keycode 133 was handled.
