I have CapsLock mapped to Control, but sometimes CapsLock turns on anyway. But with CapsLock mapped to Control, I can’t turn it off.
How can I turn CapsLock off from a script or from the command line?
It turns out this is not super straightforward. I was hoping for a single command, but it ended up being a little more involved. Here’s a short Python script that turns off CapsLock when executed. I have it saved as uncapslock.py, very creative.
#!/usr/bin/env python
from ctypes import *
class Display(Structure):
""" opaque struct """
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)
