Hi there,
I recently installed Fedora on my Acer Aspire Switch 10 SW5-012 and everything works fine but backlight control. I tried adding kernel parameters (acpi_backlight=vendor, acpi_osi=Linux, ecc…), dsdt overlay, modify /sys/class/backlight/acpi_video0 (only directory I found), xbacklight, nothing works! Slider and FN key modify brightness in acpi_video0 but the screen backlight doesn’t change. Can somebody help me, please?
