Automatic laptop brightness

[elimelech007]

On Linux:

#crontab -e

0 08 * * * DISPLAY=:0 xbacklight =20

Since xbacklight does not work for me, I'm trying to do it through
brightness:

36 18 * * * root DISPLAY=:0.0 && /usr/local/bin/xbrightness 59501 1.3

But it doesn't work! Why?

Starting with FreeBSD 13.0, there is backlight(8) if you wanna give that a shot. Works pretty well on my laptops.

That's odd. Unfortunately no longer developed for FreeBSD, upstream. I'll take a quick look in VirtualBox.

$ pkg install graphics/intel-backlight

.config/scripts/backlight:

#!/bin/sh

if ! [ ${intel_backlight} -eq 100 ]; then
    intel_backlight 70
fi

/usr/local/etc/doas.conf:

permit nopass your_user as root cmd /home/your_user/.config/scrtipts/backlight

Run as root (not the norm, I simply haven't created a user account in this test environment):



elimelech007 is the Gammy window obscured, or maybe unexpectedly minimised to the system tray?

I have SiS 315 integrated graphics, no INTEL!
