My laptop (a Toshiba Sattelite) runs far too bright, even in the ambient light from outside in the day, and I need to be able to dim it below its minimum setting.
~#cat /sys/class/backlight/acpi_video0/brightness ~#0
Setting it below 0 will not work, and apps like
flux even with some hackery to force it to night mode via script by rolling the timezone fails to do too much and leave colours of course yellowed.
Is there some sort of method to set it below its minimum somehow? (uses some integrated nvidia card by the way)
Is there a program I'm missing that will artificially dim it by overlaying transparent black?
