Graphical session crashes if two external monitors are plugged with DisplayLink dock
Hi there,
First of all, thanks for having considered Linux users. I have been waiting for DisplayLink on Linux for a long time, and was very excited when I found out that there was now a solution. However, for some reason, I can't use my Lenovo Dock USB 3.0 with two external monitors connected to it. My setup is the following: - a laptop running Mint 17.3 Cinnamon - a DisplayLink dock with 2 external monitors connected to it with DVI connectors I am not trying to have a triple-monitor setup, my laptop already stutters enough with 2 x 1920x1200. I would just like to turn off the laptop's built-in monitor when the Dock is connected, and rather use the two external displays. Unfortunately, it doesn't work and every time I connect the dock to the laptop, the graphical session crashes, and I'm asked to log in again. I do it and it crashes again immediately. It will do so until I disconnect one of the external displays (only one stays connected to the dock). At this point, the session will not crash anymore. If I try to connect the second external display, then it crashes again. If I first turn off the laptop's built-in monitor and then connect the second external display, then it crashes again. There is no way I can use both external monitors at the moment. Any ideas? Below are details of my hardware and OS: Code:

Anyone having better success with two monitors connected to a DisplayLink dock, on another Linux distribution maybe? It's starting to be a bit awkward at work with my newly purchased screen still not being turned on, people probably wonder why I prefer using the 12.6" screen of my laptop over the 24" that I just asked.

This kernel version is a bit too new for the Ubuntu driver. EVDI is already ready to support 4.x line, however there's been an incompatible change in libevdi (that changed the API) so DisplayLinkManager would not work with the library built off "devel" branch (we use "master" for Ubuntu releases).
We do plan a refresh for the Ubuntu driver that would enable 16.04 LTS for example - I cannot give exact date though. In meantime, you could try compiling a version of https://github.com/DisplayLink/evdi from devel branch if you get rid of commit 09b525b which changes the API - then I think this would stil work with DisplayLinkManager, but obviously should contain other changes that enabled 4.x compatibility. Alternatively, you can use devel branch as is, and try to re-introduce the function that changed signature Code:
void evdi_connect(evdi_handle handle, const unsigned char* edid); Please do reply here if you do it and it works. Cheers, Michal |

Hi Kabouik,
My setup is very similar to yours, almost identical. Though our laptops are slightly different, the specs are pretty much the same. (I am using a Lenovo Thinkpad X1 Carbon.) The only differences are: - Using Kernel 4.5 - Main laptop monitor max resolution is 1600x900 - 4GB of RAM - GCC 5.2.1 & 4.9 Thought, I am able to use 2 monitors @ 1900x1080, but it didn't work off the bat, had to do a few reboots and playing around with the cable. There has been a few issues that I've experiencing: - Dock Disconnections - Session logs out when 1 or more monitor turns off - Both mouse and keyboard lags (wireless) - Timeout on Data transfer over Ethernet - System Freezes Most of these problems occur after the system has been in suspend mode, so a reboot usually fixes it. In your case, maybe try re-installing the drivers? http://displaylink.org/forum/showthread.php?t=64470 (simfocien made patches based on the codesource from the github) Can't wait for the new drivers. Code:

Eagerly awaiting this update - I'm on Ubuntu 15.10 (kernal 4.2.0) and have it *mostly* working to the point where I have 2 external monitors functioning most of the time, but still experience X or kernel crashes due to DisplayLink once or twice a day. Please update this thread when there is a compiler-free way to try the new 4.x branch!
