How can I disable Logitech MX Keys Wireless Keyboard backlight on 20.04. I want to turn off LEDs completely with a GUI or command line tool.
I was able to turn off LEDs of my Logitech mouse with Piper app.

Press and hold F6 until backlight is off.
C. Rogers is wrong Pressing Fn + F4 or F5 will only control the brightness of your monitor.
You have to press either F7 to turn the backlights off, or F7 to turn the urge backlight back on.
1Hold the function key (Fn) and hit F6 to turn off the backlighting and F7 to turn it back on. Not F4 or F5 as previously stated.
0There's no need to install anything. Just hold the Fn Key and tap F4 or F5 to lower or raise brightness on the keyboard. Was looking for answers, when the icons on the keys were right there staring me in the face. Hehe.
