Copying relevant information here so you don't have to get it from the yquake2 bugtracker:

He remapped capslock to ctrl with

  Section "InputClass"
        Identifier "system-keyboard"
        MatchIsKeyboard "on"
        Option "XkbOptions" "ctrl:nocaps,apple:alupckeys"
  EndSection

(Probably in xorg.conf)

X11 seemed to recognize that, probably from xev:
KeyPress event, serial 39, synthetic NO, window 0x1e00001,
    root 0x2ce, subw 0x0, time 260084, (1,51), root:(3429,498),
    state 0x0, keycode 66 (keysym 0xffe3, Control_L), same_screen YES,
    XKeysymToKeycode returns keycode: 37
    XLookupString gives 0 bytes: 
    XmbLookupString gives 0 bytes: 
    XFilterEvent returns: False
KeyRelease event, serial 39, synthetic NO, window 0x1e00001,
    root 0x2ce, subw 0x0, time 260156, (1,51), root:(3429,498),
    state 0x4, keycode 66 (keysym 0xffe3, Control_L), same_screen YES,
    XKeysymToKeycode returns keycode: 37
    XLookupString gives 0 bytes: 
    XFilterEvent returns: False

So the X11 keycode is 66 (capslock), but keysym seems to be Control_L, no idea what that "XKeysymToKeycode returns keycode: 37" is about exactly, but 37 is the keycode of left ctrl.

However SDL2 returns keysym SDLK_CAPSLOCK (should be SDLK_LCTRL) and scancode SDL_SCANCODE_CAPSLOCK (this part is ok) according to my little even test program: https://gist.github.com/DanielGibson/12041b57a540cbbfbaf9

ok, this is most probably a duplicate of https://bugzilla.libsdl.org/show_bug.cgi?id=2096
