We disabled the KScreen kded module and the problem went away.

"Lid closed without system going to suspend -> turning off the screen"

It seems the external monitor is recognized as Panel and so KScreen turns it off. Please provide the output of xrandr -q

kscreen restarted, lid opened but get the same result with lid closed and stopped

Maybe important: external monitor is connected via d-sub cable; dvi cable attached (to old PC) but not active (i.e. off).
Comment 5 Heiko Tietze 2015-09-22 06:52:08 UTC
It depends on the what side the notebook is placed. The issue here does not occur when it is placed to the right of the TFT display. However, shuting down the system with lid closed switches the enabled state off in KScreen. Will file another bug report.

kscreen_console bug

provides better output. Please include that when you're running kscreen with the bug
