Can't install displaylink-driver on Ubuntu 22.04

[peterau]

Previously installed the displaylink driver using these steps - using a .run file
https://support.displaylink.com/know.../615714#ubuntu
Had no joy getting a DOCK180 box working

Now installed the display link drivers using these steps - using 'apt install'
https://www.synaptics.com/products/d...wnloads/ubuntu

The attached file shows the results of running 'sudo apt install displaylink-driver'. It says the driver is installed but fails when setting up evdi. Got the recent evdi and displaylink-driver package updates. This doesn't fix the issue.

Can connect a DOCK180 docking station but can't connect to another screen using HDMI. And can access a USB drive plugged into DOCK180. Know the DOCK180 box works as it works on another Ubuntu box - both USB drives and 2 screens work connected to the DOCK180.

How do you delete the previous install so that the new install method works? Hope you can help.

removed the packages install prior to using the .run file: dkms libdrm-dev flex
ran sudo apt remove displaylink-driver but it has already been removed

ran sudo apt install displaylink-driver. It downloaded and unpacked all the packages. See install.txt. In this file was an error at the make command:
ERROR: Cannot create report: [Errno 17] File exists: '/var/crash/evdi.0.crash'
Error! Bad return status for module build on kernel: 5.15.0-79-generic (x86_64)
Consult /var/lib/dkms/evdi/1.14.1/build/make.log for more information.

The make.log file is also attached. Renamed to make.log.txt so it could be uploaded. make.log says autoconf.h or auto.conf are missing followed by "Run 'make oldconfig && make prepare' on kernel src to fix it."

Help please to fix this issue

My USB to DVI adapter was working just fine until about 2 weeks ago when I had to take my laptop with me on a trip. When I got back I hooked it up only to find my extra display connected through DisplayLink is now blank with no signal.

Just like peterau I have tried to follow the less than helpful (for a non geek) instructions at

https://www.synaptics.com/products/d...wnloads/ubuntu

to no avail. See the attached text file which contains a copy from my latest effort using the command line.

Toshiba SATELLITE L755
Ubuntu 22.04.3 LTS x86_64
Kernel: 6.2.0-26-generic

If I boot into Windoze 7 everything works just fine so the hardware is okay.

I have spent two whole days on this... Please help.

I forgot to mention that in step 8 of these instructions

https://support.displaylink.com/know...rticles/684649

"For uninstallation procedure see here."

THERE IS NO "HERE" here........????????????

[peterau]

That's a really good point. Where is the uninstall script or procedure referred to at step 8? "For uninstallation procedure see here." and there is no here.

The .run install file is 107k lines long. Going to need some help to fix this issue.

If 2 people have posted about the same issue I'm sure there are many people in the same boat.

Displaylink support, are you reading us? Over

Apparently not!!!

So... I just bought a 32" monitor and mounted it in "Portrait" mode, replacing two 24" monitors stacked one above the other, which I had been using as a single screen... (I HATE scrolling!!!)... Now, while I have less screen width, I don't have the display border in the middle anymore. I may even get to like this setup better?

In which case Display Link can go pro-create with themselves!

When and a big IF DL decides to help us, I will use one of the 24"s for "Fullscreen" mode videos (not great on a "Portrait" mode display).
