Hey guys, I've found an easier but annoying way to run DisplayLink on the latest xorg-server.

You just need to remove displaylink (and reboot) before your start x.

# add this to shutdown
sudo pacman -R displaylink

# then when you have your desktop up and running
yay displaylink

You don't need to reboot now because evdi is installed

Just unplug your displaylink screen, plug it back in and turn it on in arandr or xfce4-display-settings or whatever you're using.

Also make sure you're on

evdi-git 1.7.0.r6.g9b124a6-1

I'm running evdi-git 1.7.0 and xorg-server 1.20.9-2 with 2 displaylink screens and an hdmi screen, plus laptop screen.

I just can confirm the segmentation fault after upgrading to xorg-server-1.20.9 and that downgrading it via

sudo pacman -U /var/cache/pacman/pkg/xorg-server-1.20.8-3-x86_64.pkg.tar.zst

helps.

@xamindar I just checked with 5.8.5-arch1-1 (but connected to USB2 port, see below). No problems either.

I am using the official and most recent core/linux-lts kernel because the USB3 support for my chipset in 5.8.5 is currently broken in 5.8.5 (https://bugzilla.kernel.org/show_bug.cgi?id=208911)

If you keep getting crashes with displaylink/evdi/xorg-1.20.9 please file bugs upstream.

@bnavigator you are using a very old kernel (by Arch standards), so it working for you does not apply to the issue we are all having.

xorg-server-1.20.9-1-x86_64.pkg.tar.zst didn't work for me. Downgraded to xorg-server-1.20.8-3-x86_64.pkg.tar.zst and it's mostly working. Doesn't seem to matter which window manager I use. Package versions and abbreviated hardware lists below. Everything was working fine before the upgrade.

Please let me know if I can help.

Could you state kernel version and graphics card/drivers?

Displaylink with xorg-server 1.20.9 works fine here with kernel 5.4.61-1-lts on Intel HD Graphics 4000 (xf86-video-intel)

both my external monitors stopped working after upgrading.

First tried with evdi-git as described by @homelessuser, but that did not resolve the problem.

What worked out for me was the xorg-server downgrade as described by @xamindar.

Same here. works fine in combination with xorg version 1.20.8 but with 1.20.9 everything just crashes.

@homelessuser thx. I downgranding. Now is work!
