Monitor is not detected
Greetings,
I have an ASUS ZenScreen MB16AC portable monitor which is supposed to work with DisplayLink as in here: Code:
https://www.displaylink.com/products/find?cat=2&br=-1&usbc=1 1. Install evdi: Code:
# dkms status evdi, 1.9.1, 5.12.14-arch1-1, x86_64: installed Code:

I think this might be because you have a kernel version higher than what the pre-built driver works with. I am using the 5.13.9 kernel right now and monitors aren't detected (everything else works though). From what I can tell from their github evdi repo, 5.12 kernel support was added in March, but not sure if it was part of the evdi version that is shipped with the 5.4 display link driver.

After having the same issue myself by using a mainline 5.13 kernel in Pop OS, I managed to get the monitors working by having a look at the guide for porting the driver to other distros here: https://support.displaylink.com/know...r-to-other-lin
A small summary though (only tested in PopOs, but should probably work in most Debian/Ubuntu based distros): 1. Make sure you uninstall the current EVDI driver. Do this by calling the currently installed DisplayLink installer file with a "uninstall" argument. For example: Code:
sudo ./displaylink-driver-5.4.0-55.153.run uninstall Code:
./displaylink-driver-5.4.0-55.153.run --noexec --keep Code:
cd ./displaylink-driver-5.4.0-55.153 Code:
curl -L https://github.com/DisplayLink/evdi/archive/refs/heads/devel.tar.gz -o evdi.tar.gz Code:
if ! tar xf "$TARGZ" -C "$EVDI"; then Code:
if ! tar xf "$TARGZ" -C "$EVDI" --strip-components=1; then Last edited by karly; 08-23-2021 at 05:25 PM. Reason: add -L to curl |

I did exactly the steps Karly said, but it doesn't work. When I connect the displaylink docking station to my USB and i check de status of the doplaylink-driver service, I get:
displaylink-driver.service - DisplayLink Driver Service Loaded: loaded (/lib/systemd/system/displaylink-driver.service; static; vendor preset: enabled) Active: activating (auto-restart) (Result: exit-code) since Wed 2021-08-18 13:12:56 -03; 4s ago Process: 4262 ExecStartPre=/bin/sh -c modprobe evdi || (dkms install $(ls -t /usr/src | grep evdi | head -n1 | sed -e "s:-:/:") && modprobe evdi) (code=exited, status=1/FAILURE) |

Great! Just found this post via GitHub - and I **think** it worked on Ubuntu 20.04 (no errors). I'm running vanilla Ubuntu with the System76 PPA for a System76 GalagoPro laptop.
Just an FYI for Ubuntu; the two commands should replace the <./> with <bash>. |

Thank you karly! I knew I had an issue with EVDI but didn't know how to go about fixing it. Replacing the tarball in the installer as you described worked perfectly.
All the displays connected to my dock work now. Pop!_OS 21.04 Kernel: 5.15.5-76051505-generic Dell Inspiron 15 5510 |
