[listout]

Original patch was suggested by Crashdummyy.

Before submitting the PR please make sure you have run ci scripts:

• ./ci/build_against_kernel (see --help for all options) We need backward compatibility and this script is a handy way of testing build compliance with many kernel versions.
• ./ci/run_style_check We want to be as style compliant as possible. Again, this is a handy way of checking it.

If you have more than one change consider creating separate PRs for them; it will make the review process much easier. Also provide some description (links to source code or mailing list are welcome - this might help to understand the change).

Thanks for the contribution!

Switched to Fedora 38 and the dock works out of the box without even having to install the displaylink driver. <:D

Thanks for the tip!

Checked and tested:

Working like a charm on Ubuntu 23.03 - Beta. "Linux Proton 6.2.0-19-generic #19-Ubuntu" Working like a charm on Pop OS 22.04 with kernel 6.2.0

So, am I right, Fedora 38 supports displaylink out of the box?

I highly doubt that. That would imply that we dont need evdi as dkms module as well. Im on 6.3.0-0.rc6.20230416gt3e7bb4f2.254.vanilla.fc37.x86_64 and once I unload evdi my displays stop working ( as expected )

I've had no issues after switching to Dell WD19TB.

Yes, it works without installing the displaylink driver. It's on a Lenovo laptop connected to Lenovo dock. Can't see evdi in dkms, so I'm not sure what driver it's using or how it works. Let me know if you want me to post any command.

I just installed Fedora 38 beta and my dock wont work without those drivers. Maybe it depends on the dock but I guess yours probably might've worked without displaylink anyway

The same dock did not work ootb in Ubuntu 23.04 and not with displaylink either, which is why I came here in the first place.

Upgraded from Fedora 37 (which recently had stopped working with DL) to Fedora 38. For me it does not work out of the box. I applied (at least I think I did) the patch and then other functions where undefined. I'm left with Apr 20 01:45:54 fedora systemd[1]:displaylink-driver.service: Consumed 8.296s CPU time.

Well it used to run so you can actually just replace the files.

Btw they published v5.7 on the synaptics page which uses the 1.13.1 now. I made an copr in case anyone using fedora is interested and Ill try to keep it up to date

[displaylink-emajewsk]

Closing this, as the 5.7 standalone driver has made its way to the Synaptics download page
