Looks like your md5sum command is broken.

Here is what it should look like:

% export LC_ALL=C
% which md5sum
/usr/bin/md5sum
% pacman -Qo /usr/bin/md5sum
/usr/bin/md5sum is owned by coreutils 8.32-1
% md5sum --version
md5sum (GNU coreutils) 8.32

When trying to install this package, after installing evdi-1.7.0 I get the following error:

Verifying archive integrity... 100% Error in MD5 checksums: print mode: md5sum <file> <file check mode: md5sum -c <checksum is different from 7ba0e635b6284f0651177ec1e63381d0 ==> ERROR: A failure occurred in package(). Aborting... error making: displaylink

I'm trying to debug, but I think it's their .run install scrit which is broken... It seems that they are using md5sum like this cat "binary_data" | md5sum, which is not working at all if I test. The only way I'm able to do this is with "md5" command...

Found more, after extracting it from ubuntu vm, I copied everything like PKG does. The driver is working, but when I connect displaylink, I can switch to the screen, whitout problem, but when restarting lightdm, no more screen, and huge crash in the journalctl. I tried connecting usb before boot, same problem. I tried switching back to the laptop screen before restarting lightdm, same problem. My kernel version is: 5.8.14-arch1-1

Thanks for the hint @sickcodes. Please also comment in evdi and evdi-git as they need to make the adjustments for supporting kernel 5.9. Nothing to do in the displaylink package.

Kernel 5.9 fix authored by @abucodonosor https://github.com/abucodonosor

sudo pacman -R evdi-git #used -Rns
yay --getpkgbuild evdi-git
cd evdi-git
sed -i -e s/DisplayLink/sickcodes/g PKGBUILD
makepkg -si
sudo modprobe evdi
sudo systemctl disable displaylink.service
# removing 99-displaylink.rules is necessary for me
# sudo rm sudo /etc/udev/rules.d/99-displaylink.rules
reboot
sudo systemctl start displaylink

His fix works for 1.7.0 too.

@Zeddie: See comments from last May. Does your terminal introduce a flag -title through an envvar? Maybe we need to filter that out for the Displaylink install script.

Using pamac or yay:

Failed to parse arguments: Unknown option -title

Hi @olive,

the specification is clear: Use any package which provides evdi in version 1.7.0. Your enumeration of options is correct. See also my comment in evdi-git

You could also create another package evdi-1.7 and submit it to AUR.

It is actually not very clear why there is an evdi 1.8 on the AUR.

That is a question you have to ask to the evdi package maintainer.

Is that of any use without a compatible displaylink?

No, it is not. But with Kernel 5.9 coming, the situation will change. I expect a new displaylink to be released eventually.

Can we get clarification about what is exactly the evdi package we are supposed to use? The only evdi=1.7 is the git version, is that the version that is recommended? Usually git means latest development and unstable but maybe there is a good reason to use it here. Another possibility is to fetch an older snapshot of the evdi package (currently on the 1.8 version) and to use it. It is actually not very clear why there is an evdi 1.8 on the AUR. Is that of any use without a compatible displaylink?

I see same driver on official i-tec web site manufacturer for dock station. I can connect 2 screen 2160x1440 to my laptop FullHD and it is working to show display desktop with xrandr. But get mouse flickering and icon mouse and some squares draw on desktop (it is very borring). I use XOrg, Intel i915 and nvidia propietary driver with GTX 1660 Ti GPU card on Gigabyte laptop Aero15. Also, the numeric keyboard part stop working when i use displaylink with 2 monitors.

What is the solution to fix these annoying ugly problems ?

I have two monitors side by side. With recent updates to displaylink, when I move my mouse cursor over to the right side of the left monitor, the cursor is on the right edge of both monitors.

Any way to fix that?
