Hi Community,

I was wondering if someone could help me out with the USB-HDMI converter not working.

I have successfully installed:

#evdi-git 1.12.0.r1.gb884877-1 (+22 0.50) (Installed: 1.12.0.r6.gbdc258b-1)#- still installed

#displaylink 5.6.1-3# - Did not work. I just  its uninstall it


Now, i was able to see the 2x usb-hdmi adapters when running ./displaylink-driver-5.6.1-59.184.run, but it does not retains once rebooted.

Can someone help me to figure this out?

Thanks in advance!
 :D


 

Generally the solution would be to:
1) Create a corresponding runit service file based on  the systemd service.
2) The displaylink package needs a modified udev.sh script to reflect starting and stopping using the runit service.

Here is a possible run file for the displaylink runit service based on the systemd service file:

#!/bin/sh
PATH=/usr/lib/displaylink
sv check <display-manager>
exec /sbin/modprobe evdi
exec /usr/lib/displaylink/DisplayLinkManager

The input the <display manager> you are using.
Not sure if there is a generic term similar to graphical.target but the display manager application should be close.

The udev.sh would need the start_service and stop_service lines modified to reflect using runit.

start_service()
{
   sv up /run/runit/displaylink
}

stop_service()
{
  sv down /run/runit/displaylink
}

Update the displaylink's PKGBUILD sums to pick the changed udev.sh. I would clean up the systemd stuff as well from the PKGBUILD. Build and install.

Now you can test.
Some modification(s) maybe required to get a working solution for your setup.
Consider this a rough guide as I do not have the hardware to test with.

When you do get it all working, creating a runit package for it then uploading it to AUR would help all future displaylink runit users.

Hi, I'm also working to setup the same thing  :D ! I can try to setup a AUR package and I will let you know how it goes.

I created a draft PR here: https://github.com/e-dong/aur-displaylink-runit/pull/1

I would like feedback please before publishing this on AUR!

For the  run script I ended up using:

#!/bin/sh
PATH=/usr/lib/displaylink
/sbin/modprobe evdi
/usr/lib/displaylink/DisplayLinkManager

Using exec didn't work and I'm not using a display manager. I have a startx script that starts up dwm, so there isn't a runit service for this.

There is also a displaylink-sleep.sh script that gets copied to here:

"$pkgdir/usr/lib/systemd/system-sleep/displaylink.sh"

Is their an equivalent for runit?

Other than that, I just need to figure out how to generate new SHASums
