Title: Can't adjust brightness
Post by: Bluepixel on November 23, 2020, 06:50:57 PM

Hi there, recently I had set up my new Tiny Core 11.x system
on my laptop, and everything just works as it should.

For some reason however, I can't seem to adjust my brightness..
I tried installing xbacklight and xrandr, and messing with that for
a bit, but all I get is an error.

Quote

xrandr: Server RandR version before 1.2

I also tried adjusting my brightness through the backlight method,
but after a lot of problems I realized that I'm on an AMD cpu..
Yeah, I oftenly switch systems so I lost track, most use Intel for
good reason.. Either way, if there is any solution to adjusting the
brightness, please let me know!

Cheers!

TinyX does not support many things full Xorg does.

Something like this will adjust the brightness on intel hardware:

Code: [Select]

$ echo 500 | sudo tee /sys/class/backlight/intel_backlight/brightness

Hi Bluepixel

First of all, you need to check your computer's video card model and whether the system has the appropriate video card driver. If not, you can install the video card driver and Xorg and then try it again.
