Xorg.0.log and output of xrandr, cpuinfo and dmesg for all those kernels
After upgrading my Ubuntu 16.04.1 (kernel 4.4) to 16.04.2 (kernel 4.8), I got a
"fake" monitor called eDP-1, which now "extends" my real VGA monitor called
DP-1.
So when I boot into the desktop I only see a wallpaper, as the menus are shown
in the "primary" ghost monitor. Running `xrandr --output eDP-1 --off` works
around the problem.
I also tried with kernel 4.11, and I have a fake monitor there too, but now
it's called DP-1 instead of eDP-1, and my real VGA is now called DP-2.
This is on a i3-6100 CPU.
To sum up:
Kernel 4.4: HDMI-1, HDMI-2, DP-1 (real)
Kernel 4.8: eDP-1 (fake), HDMI-1, HDMI-2, DP-1 (real)
Kernel 4.11: DP-1 (fake), HDMI-1, HDMI-2, DP-2 (real)
I'm attaching a .zip file that contains subdirectories with Xorg.0.log and the
output of xrandr, cpuinfo and dmesg for all those kernels.</pre>
