FYI, I noticed that if I use the Fn+F4 key on my laptop (which is the
'lower screen brightness' function key) and drop it to 0% (as reported
by a screen brightness overlay in KDE, if I'm logged in), my backlight

I have a Lenovo 580, and on it too the screen goes black after the boot

I tried, and as with Ron A. in comment #5 to this bug, I, too can
'blindly' log in to my KDE desktop after entering my password. (So
basically, the screen goes completely off, then KDM comes up). After
logging in, the screen becomes active again.

I just upgraded from Kubuntu 12.10 to 13.04, and have been struck by
this. Unless I attach my external monitor (via HDMI) during boot, my
laptop's LCD goes blank after showing the "Kubuntu" logo for a few

Diego Carrera Gallego,
Please run the tool sudo intel_reg_dumper once when the screen is working
correctly, and once with it showing the blank screen / out-of-range error, and
