Hi,
On my Asus Zenbook UX31A I used to be able to control the backlight in
both X and on the console using wsconsctl display.brithness=xx. After
upgrading to 5.6 this stopped working. Whatever I put in place of xx,
the output reports:
display.brightness -> 100.00%
I've attached dmesg output below.
I might be able to find out what change caused this regression if
somebody can hint where to look. I've already crawled through most of
the intel drm code, but I think this must be somewhere in the ACPI
layer. Where should I look?
Thanks in advance,
Frank
