Hi I'm inquiring about when support for Ubuntu 18.04 and the Linux 4.15 kernel. I sent a paper letter to the Palo Alto office, but have not received a response.

        I am using a laptop with one usb c displayport alt mode port and one hdmi port. I connect 2 external monitors to the laptop and another monitor via displaylink adaptor i.e. 4 monitors in total in windows 10.

        However when I try to do the same within Ubuntu, using the displaylink adaptor as the FOURTH screen will cause all screens to go haywire, i.e. all 4 screens will display the same 'messy' screen. if I unplug the Hdmi monitor, i.e only 3 screens in total, everything goes back to normal.

        So I suspect that Ubuntu havent been coded to handle 4 screens within this setup.

        Does anyone know how to fix this issue? is there a manual setting to override the display configuration?

        The 18.04 installer doesn't work.

        Unfortunately solution provided to disable "suspend on idle" did not resolve issue,
        #### Disable audio suspend
        * `sudo gedit /etc/pulse/default.pa`. Comment out the line indicated below.

        ```
        ### Automatically suspend sinks/sources that become idle for too long
        # load-module module-suspend-on-idle
        ```

        Have two ThinkVision HDMI monitors connected by Displaylink, neither is detected.

        Display-Link does not detect connected monitors on Ubuntu 18.04.1 LTS. I used displaylink-driver-4.4.24.run.

        Solution found on the forum for those who have problems with monitors that goes on sleep mode randomly :

        #### Disable audio suspend

        ```

        Hi,
        I have the same problem whit the backouts. It randomly turn out the monitors and I have to reconnect the device. (I use DELL - notebook, monitors and dockStation) Can you please help me?

      • John commented  ·   ·  Flag as inappropriate

        Same problem here. Screens turn off randomly on ubuntu 18.10. Have to disconnect and reconnect the device. Very annoying.

      • Yulia Guskova commented  ·   ·  Flag as inappropriate

        I installed last version of driver. And my screens turn black from time to time. What should I do?

      • Anonymous commented  ·   ·  Flag as inappropriate

        Could you please tell us when do you plan to release a version for Ubuntu 18.10 ?

        Thank you @Ablan, this is great news!
        @C.Rogers, I installed but wherever my cursor is it freezes that portion of the image so that when I scroll a little box approx 50x50p stays put until i move it. I also experience an issue where the screens will go black for no reason. Hoping an official ubuntu driver will fix these issues.
