On Dell E5570, gdbus call --system --dest org.freedesktop.UPower --object-path /org/freedesktop/UPower/KbdBacklight --method org.freedesktop.UPower.KbdBacklight.GetBrightness
works well, returns 0, 1, or 2, depending on keyboard backlight level OFF, DIM, FULL. But gdbus call --system --dest org.freedesktop.UPower --object-path /org/freedesktop/UPower/KbdBacklight --method org.freedesktop.UPower.KbdBacklight.SetBrightness i switches backlight to full power independently of parameter i. Even backlight timeout is deactivated: backlight just does not switch off. This deactivated timeout "setting" made by Ubuntu is persisted. Even if I reboot into DOS or BIOS setup, backlight just stays on. I have to setup the timeout vale in BIOS again to activate the timeout function. Ubuntu 16.04 with unity-settings-daemon version 15.04.1+16.04.20160209-0ubuntu2. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1510344 Title: Keyboard Backlight Turns on at boot To manage notifications about this bug go to: https://bugs.launchpad.net/dell-sputnik/+bug/1510344/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
