after installation and reboot system goes in terminal mode

[sjovanovic91]

Hello,

for first I would connect a display with a usb to hdmi adapter and I use Buster 10 with Kernel 4.19.0-22-amd64.

After installation and reboot, my Debian Buster boots in terminal mode. I cant start the X11 -Server, the error: "no screen founds". And the sudo ./displaylink-debian.sh --debug shows me the error "Cant open Display".

After searching I found the solution to remove the /etc/X11/xorg.conf.d/20-displaylink.conf. Than my system boot normaly in KDE GUI.

After the display detection with xrandr --setprovideroutputsource <prov-xid> <source-xid> and the the command sudo ./displaylink-debian.sh --debug show my this:

Starting Debug ...

I think my system detected the displays but the screen with the usb to hdmi adapter have no signal. The reason is maybe because now the File: /etc/X11/xorg.conf.d/20-displaylink.confis not found ..

I hope someone has a solution.

Thanks

There must be a configuration issue in the /etc/X11/xorg.conf.d/20-displaylink.conf file? Can you post the content please.

Dropping this here as update and for myself as a future reference, and for anyone that may be having some trouble with getting the driver installed and running. Much of this is in the documents and post install guides, this is just a centralization of that data.

I am having the same issue. I have a fresh install of Debian11 (Kernel 5.0.10-20-amd64) on a Lenovo P53s.

After running the initial install script and prompted reboot my system hangs at starting display link drivers. Looking at sjovanovic91 post about removing the 20-displaylink.conf file to enable their system to boot correctly. I booted into recovery mode and made a copy of the file as requested by Barabazs and have attached it here, then removed it from the /etc/X11/Xorg.conf.d path and rebooted successfully. After reboot I noted that the driver was not loading (secure boot needed to be disabled), rebooted into BIOS and disabled. Now the driver loads, I have all three monitors being identified by xrandr.

There is a note buried in the original docs that says renaming the 20-displaylink-conf file may be a good fix, in my case that was 100% accurate and the file does not appear to be needed. I would be curious to see what you (Barbazs) see's in the file that may make it work as expected when put back into the path.

Adnan, Thank you for getting this setup and keeping it current! I have been using this driver for the past couple of years with great success (generally after a little digging--- but that is part of the fun right?)

Cheers!
