           Summary: Screen blank after 4.6.4 -> 4.6.5 update
           Product: kde
           Version: 4.6
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: wolf.behrenhoff at gmx.net


Version:           4.6
OS:                Linux

I am using a laptop which is usually connected to a docking station and two
external monitors, i.e. HDMI1 and HDMI2 (and LVDS1 switched off) - this is set
as my default screen setup.

When using the Laptop without docking station, there is only LVDS1 available.
After logging in, the screen just turns blank in 4.6.5! (luckily I know to
launch a konsole and use xrandr, so I was able to switch on the screen again)

Any saved screen setting must not lead to a completely blank screen. At least
one screen must always be switched on.

To my understanding, a screen configuration which can be set as default in the
"system settings->display and monitor" should only apply if the connected
devices are the same - otherwise one cannot use a laptop stand-alone and with
docking station.

Reproducible: Always

Steps to Reproduce:
store HDMI1 and HDMI2 --auto and LVDS1 --off as default, then start the machine
without the external monitors

Actual Results:  
screen blank

Expected Results:  
screen not blank
