change:
<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"/>
Step 2: Bios
In my bios file I had to find the settings for the keyboard timeout and change it to something else. So if it was set to 5 seconds then I had to change it to 10 seconds. If it was set to 10 seconds then I had to change it to 5 seconds.
Once I rebooted my system the keyboard returned to the expected behavior.
This issue affected me with a new Dell E5470 on 14.04
The issue would go away with a factory reset but after doing updates it would reappear.
The way I eventually got it fixed was
Step 1: as stated above
Edit file 1/system. d/org.freedeskt op.UPower. conf
/etc/dbus-
change: n="org. freedesktop. UPower"
send_ interface= "org.freedeskto p.UPower. KbdBacklight" /> n="org. freedesktop. UPower"
send_ interface= "org.freedeskto p.UPower. KbdBacklight" />
<allow send_destinatio
to:
<deny send_destinatio
