https://bugzilla.kernel.org/show_bug.cgi?id=198885 --- Comment #2 from Przemek (soprwa@xxxxxxxxx) --- Hi Michel, Thank you very much for insane-fast response. Yes, "actual_brightness" is a bad example, same occurs on this file without "amdgpu.dc=1". Here are values from requested files: "/sys/class/backlight/amdgpu_bl0 # cat brightness 3" "/sys/class/backlight/amdgpu_bl0 # cat max_brightness 255" "/sys/class/backlight/amdgpu_bl0 # cat actual_brightness 3" I have tried different values also: "/sys/class/backlight/amdgpu_bl0 # echo 100 > brightness bash: echo: błąd zapisu: Bad argument /sys/class/backlight/amdgpu_bl0 # echo 50 > brightness bash: echo: błąd zapisu: Bad argument /sys/class/backlight/amdgpu_bl0 # echo 10 > brightness bash: echo: błąd zapisu: Bad argument" -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
