<pre>See attached dmesg with kernel 3.18.6, please.
I booted with no external monitor connected.
The internal display was black and I could not switch to a tty.
I used ssh to connect and did the first dmesg. This one ends with:
[ 261.949574] SELinux: initialized (dev tmpfs, type tmpfs), uses transition
SIDs
Then I connected the external monitor and did the second dmesg. This ends with:
[ 415.478230] [drm:valleyview_update_wm] Setting FIFO watermarks - A:
plane=111, cursor=6, B: plane=109, cursor=2, SR: plane=0, cursor=0
Last I logged in an did the third dmesg (see attachment, which contains all
messages).
If I boot with the second monitor connected, the internal monitor goes to black
after "fb: switching to inteldrmfb from EFI VGA".
The external monitor is on and later I can login (blindly), which switches the
internal monitor on.</pre>
