Displaylink and lightdm

Robert_29 · 08-09-2015, 12:14 PM

I'm running Ubuntu 15 with Cinnamon. After start the DisplayLink service is not running as shown by systemctl status

after start and login I can run

sudo systemctl start displaylink.service

which starts the service and finds the other monitors:

I've tried changing the After statement in /lib/systemd/system/displaylink.service to lightdm.service.

Probably missing something simple.

Hi Robert,

Thanks for the report. Indeed, the currently installed systemd service configuration entry needs some polishing - for this release we have focused on upstart as Ubuntu 14.04 LTS was the target.
Systemd service file needs changes to start DisplayLink Manager automatically on boot - we will include a fix for this in next releases. For now, you can try modifying it yourself - let me know if it worked:

Add the following section to /lib/systemd/system/displaylink.service:
Code:
```
[Install]
WantedBy=graphical.target
```
Use this command to enable starting the service automatically:
Code:
```
systemctl enable displaylink.service
```

Michal,

Just confirming that this addition for systemd seems to work on 15.04

I have linux kernel version: 3.14.1-031401-generic
I am running Linux Mint 17.2

I execute your .run file and it gives me everything listed in the example except that it doesn't actually run anything.

Looking at this post you guys are making reference to a program systemctl that I don't seem to have. You also state to edit a file in /lib/systemd/system/displaylink.service that I also am missing.

Could anyone tell me what I need to do to get the monitor to work?

Thanks,

Glenn
