I guess your Linux kernel 3.18.20cobalt might be too old for your new computer.

Try some newer kernels?

No more luck using 4.1.12 kernel in opensuse 42.1 leap

I know there are mainline kernels for Debian/Ubuntu users to try.

http://kernel.ubuntu.com/~kernel-ppa/mainline/

But I have no idea if SUSE Linux also provided the similar way for SUSE users.

You may need to put "drm.debug=0xe" into the kernel parameter and reboot the system to collect some system log.

Did you check the brightness value after you change it?

Yes, the value is well written after writing it.
Here is the log

I think the first step is to identify which backlight interface is able to actually change the brightness.

Usually there are two backlight interfaces under /sys/class/backlight/, i.e. /sys/class/backlight/acpi_video0 and /sys/class/backlight/intel_backlight.

However you may see other different backlight interfaces under /sys/class/backlight/. It depends on what hardware you are using.

Executing `cat max_brightness` under those folders can see the max brightness and then you can execute `echo $(($(cat max_brightness)/2)) | sudo tee brightness` to adjust it to about 50% brightness.

only /sys/class/backlight/intel_backlight is present.
max_brightness is 937

these commands have no effect on display brightness:
echo 0 >brightness
echo 468 >brightness
echo 937 >brightness

Steph

Hi,
I have seen you were working on brightness. Right, but this is useful only if many worlwide users would be able to activate it.
I have never been able to make it working on my intel systemes (core i5 - 4300u , core i3 ...)
Very difficult to check where the problem is coming from, altough you have either an intel_backlight or acpi_backlight folder in the sys directory
Regarding many many posts on the web, this sounds tricky and difficult to know why it has not worked, or simply the documentation is lacking ....

     drm/i915: respect the VBT minimum backlight brightness

The backlight class 0 brightness means the PWM min and it does not turn
off the backlight. After kernel 3.18, the backlight class 0 brightness
is used to turn off the backlight and the PWM min is missing.

Because of

commit e6755fb78e8f20ecadf2a4080084121336624ad9

     drm/i915: switch off backlight for backlight class 0 brightness

Use "VBT backlight PWM modulation frequency 200 Hz, active high, min
brightness 10, level 255" as an example. It means the VBT min is 10
out of [0..255] and the PWM max is 937 from other place so the
corresponding PWM min should be 37 (10 * 937 / 255).

When we set backlight class 0 brightness, the backlight is turned off.
Althought the PWM value is 37 when the backlight is off but it is
useless. When we set set backlight class 1 brightness, the backlight is
on but the PWM value is 38 and it doesn't match the corresponding PWM
min of the VBT minimum backlight.

And it has another minor issue that there are some backlight class
brightness values are mapped to the same PWM value because the backlight
class brightness range is larger than the valid PWM brightness range.

The backlight class brightness range [0..937]
The valid PWM brightness range [37..937]

This commit makes that backlight class 1 brightness means the PWM min
and backlight class max_brightness means the PWM max, and the ranges
become

The backlight class brightness range [0..901]
The valid PWM brightness range [36..937]

That's no backlight class brightness value mapped to the same PWM value.
