Problem with Caps Lock key in Elementary OS 5.1

[scellige]

Hello, If I try to use CapsLock as a hotkey for change keyboard layout there is a problem:

• If I disable CapsLock key in system settings - the script doesn't handle keypress events
• If I don't disable CapsLock key - the script works, but it also changes the state of CapsLock, and in new keyboard's layout you will type capital letters

I found a solution:
In the start of file switch-layout.py add this:

from ctypes import *

class Display(Structure):
    """ opaque struct """

And at the end of the method on_press of the Switcher class add this:

X11 = cdll.LoadLibrary("libX11.so.6")
X11.XOpenDisplay.restype = POINTER(Display)

display = X11.XOpenDisplay(c_int(0))
X11.XkbLockModifiers(display, c_uint(0x0100), c_uint(2), c_uint(0))
X11.XCloseDisplay(display)
