Hi.
I use HP ProBook 6560b (LVDS1) with 2 external Fujitsus B24T (VGA1,
HDMI2), both connected via docking station.
OS: debian testing with xfce
LVDS1 - off
VGA1 - on
HDMI2 - on
Recent (approx 1 month back) apt-get upgrade (also using latest
debian-testing.iso) made it impossibe to use this >configuration.
I'm asked for a LUKS password, i can see initial on-screen logs but when
Os tries to start X, both monitors goes black (i >cannot switch to TTY).
However when one of monitors is unplugged, OS & X starts with no errors,
then i plug the other monitor in and they both >works.

create the folder
/var/log/journal
reboot with both monitors plugged in and let the configuration fail
unplug a monitor, reboot and use
journalctl -b -1
to read the error messages
