Make sure that UEFI/secure boot is disabled!
When you are logging into your session you are using X server (X11) and not Wayland.
After install you must reboot to apply the changes.
After reboot, make sure DispayLink is running, i.e:
systemctl status dlm.service
If it's not running, start it by running:
systemctl start dlm.service
To start automatically at boot run:
systemctl enable dlm.service
Check providers, i.e:
xrandr --listproviders
If you get a list of more then one provider, it means your displays were detected.
Set provider sources, i.e:
xrandr --setprovideroutputsource 1 0
xrandr --setprovideroutputsource 2 0This will connect you to two external monitors.
There are couple of tools to help you configure screen layout of your external monitors.
Depending on your setup, to connect provider 1 to provier 0, you'd run:
xrandr --output DVI-1-0 --auto --right-of eDP1
For further reference I suggest reading: How to use xrandr
If you're GNOME desktop user, simply run:
gnome-control-center display
Another very easy and intuative (gui) tool is arandr (Another XRandR GUI)
Make sure to install it first: sudo apt-get install arandr
Since hotplug doesn't work (on Debian and Kali) and every time you connect your computer to Displaylink you'll need to re-configure your displays.
I've set-up couple of aliases which help me accomplish this in semi-automated manner.
Every time I connect my computer to DisplayLink ...
I simple run two which is an alias for setting up two external displays as primary and secondary, whilst turning off laptop built in display. So I can close the lid.
Every time I want to diconnect my displays I run one. Which turns off both external displays, turns on built in laptop display and makes it a primary (default behaviour).
I did this by simply adding following code to my ~/.bashrc
# two
alias two="xrandr --setprovideroutputsource 1 0 && xrandr --setprovideroutputsource 2 0 && xrandr --output VIRTUAL1 --off --output DVI-1-0 --primary --auto --pos 0x0 --rotate normal --output DP1 --off --output HDMI2 --off --output HDMI1 --off --output eDP1 --off --output DVI-2-1 --auto --pos 1680x0 --rotate normal"
# one
alias one="xrandr --output VIRTUAL1 --off --output DVI-1-0 --off --output DP1 --off --output HDMI2 --off --output HDMI1 --off --output eDP1 --primary --mode 1366x768 --pos 0x0 --rotate normal --output DVI-2-1 --off"Note, in case you're editting ~/.bashrc, make sure you run source ~/.bashrc to appy the changes without having to log in/out.
dmesg | grep Display output while plugging in Displaylink/var/log/displaylink/DisplayLinkManager.log fileDue to older version of libstdc++6 in Jessie, you need to download and install version from Stretch release. After package has been updated, run displaylink-debian and select "Re-install" option.
Reference: issue #42
Should you experience problems with the display either remaining black, only showing mouse pointer or a frozen image of your main screen, then this could be due to Intel graphics driver interfering with displaylink.
