Dsiplaylink Driver and Ubuntu 18.04

Hello,

same issue here

egandt · 05-09-2018, 12:47 AM

I've tried three times my laptop have Intel/Nvidia I have the latest 390 version driver installed and working. great using sddm and KDE.
However as soon as i finish installing the Displaylink 4.2 driver (which installs cleanly), and reboot, X no longer works. Well the system thinks it started, but there is no display present, this is without even plugging in the USB monitor. Even switching to runlevel 3 and then trying to start X reports no errors, but again does not actually display anything, just thinks that X is started and running.

The first time I was forced to reinstall Ubuntu 18.04, the second time I figured out that uninstalling the DisplayLink driver and rebooting repaired X. So it is definitely something to do with DisplayLink regardless of plugging in the monitor, I'm just at a loss to explain what, as it is not as if X fails to start it just fails to actually display anything (it is as if it is on a virtual monitor, but even that does not seem correct).

Ideas?

EDIT: Got it working finally, needed the displayLink monitor plugged in when I rebooted.

There is this very-very annoying box behind the cursor now when using displaylink. If I leave the mouse in one place for a few second then all is well but on moving the mouse it comes back and makes using the system difficult.
I'm running KDE Plasma with SDDM and Nvidia 390 drivers.

What do I do to remove this X behind the mouse?

This happened to me as well in Gnome. I don't think there is anything you can do about it until they release a fully supported driver.

I was able to get this somewhat working. The mouse flickering is still a problem but a minor annoyance. Seems to be that if I initialise my main monitor while the displaylink adaptor is connected it will freeze the desktop. However if the same process is completed with the adaptor disconnected the desktop is fine. After the login to the desktop connect the displaylink adaptor and initialise your other monitors. Seems to hold after a reboot as well.
