Hello,
I installed 4.4.8 and it works better but not perfect. I sometimes
manage to plug a second monitor, sometimes it freezes when I turn it on.
If the second monitor is plugged when the system boots, I often have
errors at boot "intel_dp_link_training_clock_recovery" and
"intel_wait_ddi_buf_id
Yep, 4.4.8 kernel works perfectly for me. Can change resolutions, turn
on/off displays, all works fine.
(now if only gnome was better at dealing with one hdpi screen and one
normal dpi screen!)

@Jonathan: I was on 15.10. :|
The problem with 15.10 is the trackpad doesn't work due to a bug in the
i2c driver (drivers/i2c/busses/i2c-designware-platdrv.c) for kernels <
4.5. When I upgraded my kernel to version 4.5 I started getting this

Ok, it seems as Intel has just 'forgotten' to make their newest drivers
available. That's why they are not included in 16.04.

I have a Asus Zenbook UX305CA-EHM1 M3-6Y30. It's a pretty sweetly
designed machine and Ubuntu looks and works awesome on it EXCEPT for
this external monitor issue.
I've got the Intel HD Graphics 515 using the i915_bpo driver and a micro
HDMI display port.

Mine has a usb3.1 with an adaptor providing another HDMI and a VGA port.
They all work the same, ie hardly!, so if say don't rush out and spend

It crosses my mind that as well as the HDMI output, my laptop also has a
mini display port. Does anyone have a feel for whether it's worth buying
an mini display port adaptor or cable to test whether that behaves the
same?

OK so it might NOT be gnome-related. I've had a few of these crashes
using Unity now. Attached is syslog that I was able to get after

Note: This only happens when I'm using gdm and gnome shell. I have

So this is a gnome-related bug.
