Uninstalling the Intel driver fixed the problem. It appears there is an incompatibility between the version of libdrm used in the latest Intel driver and the version that is used by the displaylink driver.

Hey there, I might have bumped into the same issue
I have a Lenovo Thinkvision and Ubuntu 15.10 with 4.20 kernel when I try to install the supplied driver via script I get similar errors, I do have Intel drivers installed but would prefer not to uninstall them... I checked and have libdrm-dev and libdrm2 v2.4.65-3 installed is there any other way to solve this? |

I uninstalled the Intel drivers using Synaptic package manager
basically I looked for packages marked by intel and with source 01.org - I switched them all to use Ubuntu/Wily own packages -- this operation was successfull and I've downgraded to Ubuntu bundled drivers but still, I would get the same error as chrisvo even after this after installing and trying to start the displaylink manager - same error perhaps I missed something -- any clues? thanks! |

I've finally managed to clean my Intel Graphics for Linux drivers following instructions at
http://theclonker.de/archive/89 (in my case I changed the origin of packages to wily, since I use 15.10) then installing again the Displaylink driver, it was successful however this solution wasn't optimal.. I noticed a decrease in battery performance and a bug in Google Chrome that forced me to disable the hardware acceleration there - this was fixed by installing the Intel drivers... |

Also with the DisplayLink driver I've noticed high CPU usage even when I am not connected to the docking station, where I've had to manually kill DisplayLinkManager. |

drm symbols not found
Ehlo,
I've encountered a very similar issue, while setting my Ubuntu 16.10 up. Some debugging showed that I had no linux-image-extra-*-generic kernel installed/ loaded. Therefore the drm.ko Kernel module was not present and could not be loaded. This can be checked easily by running 'modinfo drm', if the program complains about 'no module found' you should check 'dpkg --list | grep linux-image-extra' to see if you have a kernel that comes with drm. Once installed and rebooted the journalctl errors went away. Thanks, Michel/Tofu |
