http://bugzilla.opensuse.org/show_bug.cgi?id=1030192 Bug ID: 1030192 Summary: Keyboard backlight turns on after boot or unlock screen Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: zhx@cnzhx.net QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- [Problem] I have this problem on my Lenovo ThinkPad T470s laptop. The keyboard backlight can be controlled by `Fn+Space` well. But when it is set to be off, it will turns on after boot, or any time I unlock the screen. [Attempt solution] Following a discuss here https://ubuntu-mate.community/t/keyboard-light-keeps-turning-on-after-login-..., I changed the file `/etc/dbus-1/system.d/org.freedesktop.UPower.conf` by changing `<allow send_destination="org.freedesktop.UPower" send_interface="org.freedesktop.UPower.KbdBacklight"/>` To `<deny send_destination="org.freedesktop.UPower" send_interface="org.freedesktop.UPower.KbdBacklight"/>` And then, the backlight won't automatically turn on any more. But another issue comes up: the keyboard backlight won't response to Power Saver Management, and even the options of auto change lightness option in `System Settings` > `Power Management` > `Energy Saving` disappeared. So this is not the **real** solution. [Expected result] Keyboard backlight should not automatically turn on while booting or unlocking screen. -- You are receiving this mail because: You are on the CC list for the bug.
