Kde Neon, which is ubuntu 16.04 based. Not usable.
 

When the cable it plugged in my screen changes to a login screen and it exits my current session. Little bit annoying but can live with it.

When I login again, all the screen come on with my background but cant open display settings. only some apps work. eventually the laptop just freezes. Not even useable until dock unplugged, and sometimes reset is needed . Plugged in via 3.0 port. DisplayLink Linux Software 1.2.65

Tried all version since ubuntu 16.04 release. All have issues.
I'm trying to run two full HD monitors 1920x1080

Everything else works. USB, Sound, Ethernet

EDIT: Tried on windows 7 SP1, works fine. But I dont use Windows very offen at all.

I have a Toshiba z930
Intel(R) Core(TM) i5-3437U CPU @ 1.90GHz
6GB Ram
Dock: DELL D3100 Docking Station

Hi Displaylink,

Has anyone taken a look at this yet? If you guys could would be most appreciated.

Many Thanks
Jonny

Yes we have seen problems with KDE Neon, problems we don't reproduce when standard Ubuntu 16.04 is used on the same machine.
We have seen the immediate logouts - are you seeing segfaults in dmesg perhaps?

Would you be able to attach logs captured from your device? Maybe it would be possible to find out what's causing the general slowness. See the sticky thread for a link to support tool.

Thanks,
Michal

I have already attached Logs, please see first post.

DisplayLink used to work on my machine with neon, not without some issues. But after recent upgrade of packages, connecting monitor shows KDE splash screen or a tty or someties it's login screen for a few seconds and after that it turns to blank screen and I can't do anything with the system, even switch to tty (Ctrl+Alt+F1) to try to diagnose it.

The only thing that still works is Power button. Pressing it displays normal KDE splash screen for turning off and computer turns off in a few seconds.

If a monitor is connected during system boot, this happens in a few seconds after the login screen showing.

I was able to capture logs (attached) running from a tty session and then connecting the monitor and switching back to X (Ctrl+Alt+F7). Looks like the current KDE session is killed at this point because I tried doing the same from KDE and got no logs.

Hi Guys,

Any luck, with whats making it go wrong?

Have you taken a look at our logs?

Currently have a Dell Dock that just a paper weight until this is fixed.

Updated to 1.3.52, the issue is still there
