we need a slider control or sth instead of hotkeys for dimming/brightness
i have no access to keyboard(use touch screen) and , i can't use hotkeys(Alt pg dn..etc) to get screen dimmed, any solution or near update ?!
I had the same problem for you for a while. Eventually, I found out that I needed to hold down the function key while pressing Alt + PgUp/PgDn because otherwise, my keyboard would register only as Alt + Up/Down, which does nothing. Certainly, this doesn't apply to every keyboard but it may for yours.
