A basic tool to increase and decrease intel backlight percent.


You'll need make and some C compiler installed.


That's it.


Copy the backlight-control file to /usr/local/bin/ or somewhere similar. Then run backlight-control to get the current brightness as a percentage, or backlight-control +1 to increase brightness by 1 percent, or backlight-control -1 to decrease brightness by 1 percent. Or higher numbers for higher percentages at a time.

With i3 / Sway

bindsym XF86MonBrightnessUp exec backlight-control +1
bindsym XF86MonBrightnessDown exec backlight-control -1

With waybar

"backlight": {
    "device": "intel_backlight",
    "format": "{percent}%",
    "on-scroll-up": "backlight-control +1",
    "on-scroll-down": "backlight-control -1"
