Hm, I am on 18.04 on Thinkpad 530 and Mini Dock Plus Series 3 with three

monitor tries to sync but often times out.
It looks to me as if this is just an issue with
The status has improved significantly in ubuntu 17.10 with
nvidia-384.111-0ubuntu0.17.10.1, but it is not perfect yet.
At this moment I logout/login or lock while plugged to the dock and
using multiple screens, works seemingly. Break downs occur at less than
5%

This has been my solution since 16.04 (as noted above). But really it
should detect that it's coming back out of sleep.

At least for ubuntu-gnome 17.04, the desktop can be recovered by forcing
gnome to restart, and thus avoid a machine reboot or log out/in
The following appears to work, at least most of the times:
1. open the command prompt with Alt+F2 and type r
2. connect laptop with the docking station and
Same problems with nvidia-384.90 on both ubuntu-gnome 17.04 and 17.10.
The workarounds for 17.04 still minimize part of the issues on 17.10.

Hi guys,
I am joining this community of frustrated dock users. I am running Linux Mint

When I started this, the first hing I noticed was that having
Guys, my use-case is simple. I use my laptop moving around and
travelling, and come back to dock it with two monitors connected to the
docking station. That used to work great with 14.04 on an older laptop
but ever since I switched to the P50 with 16.04 it has been going
gradually worse. Zikmund,
Erez, try the laptop's mini DisplayPort. I use it since commenting on
this bug before, suspend works, switching resolution rather works, and
it's not that of a hassle to connect/disconnect it when you need to take
the laptop out of the dock. Yes it defies part od the dock's purpose,
but your life
Thanks for the cheerup, Fabio. I really wish to avoid reboots and X restarts
since they kill my work sessions and disrupt my flow.
Does anyone know if this catastrophe is going to improve in 18.04 or Wayland?

My experience with version 384.90 remains the same, it is usable, as long as:
1. plug the laptop and the screens to the dock before booting the machine
2. do not under any circumstance hibernate or use screen lock
If you get the blinking screen, drop to a shell, say "Crtl+Shift+F3",
and reboot
NVidia 384.90 - latest update - things seem to be taking a turn for the worse.
Now, I'm using just a single external monitor. Every time the screen sleeps
after being idle for some time, it cannot be turned back on. As simple as that.
No matter what I press. Not even by going back to console
See my post from March 22 for a possible workaround.
Notes:
1. YMMV. The changes in kernel and nvidia driver sometimes cause the desktop to
crash - not system hang, just need to login again and restart the desktop.
2. Possible improvement: try docking your laptop when the external monitors are
Same problem here on Lenovo Thinkpad P71 with Nvidia Quadro P3000.
After connecting one ore more monitors (whether over hdmi, dvi or dp) via the
Docking Station, all displays will turn black and flicker.
The only way to get the system back is to take the P71 out of the dock.

Some of the aforementioned effects disappeared for me with the following:
1. Log out
2. Get in to console (alt+ctrl+f2 - for example) and login as user.
3. Delete .nvidia-settings-rc and the whole .nv/
3. Back to graphical (alt+ctrl+f7) - NO login yet.
4. Choose Gnome Classic or Gnome (default)
It appears that it is possible to stop the flickering by forcing the
restart of X with Crtl+Alt+Bksp, this is by no way a decent workaround
but eventually it stabilizes and I get three independent screens working
properly.
My hardware is a Lenovo Thinkpad P50 with nvidia Quadro M1000M connected
I also still got the same problem in Ubuntu 17.04
But is this really (only) nvidia related?
It is working for me with 3 monitors (laptop + 2 external via docking) in

After doing a bit more investigation, I found that the older Lenovo

so for me, the dock is also just a usbhub at the moment (sadly)

I'm attaching a log of LightDM showing the repeated segmentation faults at the

I believe those crashes correlate with the display changes happening when I log
in or try to reconfigure the display, resulting in the fallback to mirroring I
documented before.
Can anyone please pay
Another attempt: I created a second dummy user, and logged in as that

However, any attempt (via "displays") to slightly change layout, order,
resolution - results in the same issues of failure and fallback to
mirroring. The
