Not able to proceed in "Building EVDI kernel module with DKMS"

[situsnow]

Hi,
Really appreciate if someone could help this issue. I run the "displaylink-debian.sh" script and everything seems working fine until it hanged in "Building EVDI kernel module with DKMS" for really long time. Below is the terminal history after I run "sudo ./displaylink-debian.sh"

Could you please confirm if this issue is not the same as: #114?

Also, is this a new install of displaylink-debian? If not, please run "uninstall" reboot and try "install" again.

Another issue which looks similar but was resolved by using latest driver version at the time: #22

[situsnow]

@AdnanHodzic Thank you very much for your reply. Unfortunately, I don't think they are similar as I don't even have error log to check what is the issue. The installation just hanged after it printed "Building EVDI kernel module with DKMS". I tried to leave it overnight but my computer hanged the next morning and I had to reboot it by force. I am really new to Linux, could you kindly advise if I can check intermediate logs anywhere? Sorry for the troubles and thank you again for your kind suggestions.

[AdnanHodzic]

@situsnow no worries, have you tried "uninstall" > reboot > "install" > reboot and if that does anything for you?

[situsnow]

@AdnanHodzic Yes, I tried "uninstall">"reboot">"install" more than 24 hours ago and still hanging.

I am also having this issue on Ubuntu 18.04. It also fails in the same way if I try to download and install the official 4.2 install script from DisplayLink as well.

EDIT: I thought I has secure boot disabled (because I thought I had checked the option when I installed), but somehow it was still enabled. Disabling secure boot fixes the hang.

Hi all,
I fixed the issue today by injecting the correct port - thunderbolts (yes, I got the wrong port for all these whole times in the stupidest way as there's also a USB embedded with the cable!!!) and upgraded the driver, things work - I don't even have to run any script.
Thank you very much for your kind help and I hope no one will make the same mistake as me :(

[AdnanHodzic]

@situsnow glad you were able to fix the problem.

@dktoao I'll update the ReadMe with this, as most of the problems are related to people not disabling the secure boot. Although it's mentioned in Post Installation Guide most people miss it.

"sudo apt-get install linux-signed-generic-lts-utopic"
worked for me!

I've just merged displaylink-5 branch with master which introduces big changes, among which are support for yesterday released DisplayLink 5.1 driver. Disabling modesetting as part of displaylink-debian as now all of it should be happening on EVDI level. I've included few more changes.

Regardless, please pull latest (git pull) changes on master and run sudo ./displaylink-debian.sh --install

After this everything should be working as expected and with this said I'm closing the issue. If the issue still persists, re-open the issue and include output of sudo ./displaylink-debian.sh --debug command.
