Custom RPM created for Fedora and others

[pgn674]

I tried plugging the adapter into the USB 3.0 port on the laptop first, and then the DVI monitor cables into the adapter (and the monitors are powered and turned on). I've also tried plugging the monitors into the adapter first, and then the adapter into the laptop. And the adapter has external power and a power button, so I've tried having that on and off in various ways too.

I have been using your RPM version 1.0.68-2 from the beginning.

How much does this depend on the graphics driver being used to run the integrated display and the VGA and DisplayPort ports (not currently being used)? This laptop has NVIDIA Optimus hardware which does some kind of mixing of Intel integrated and NVIDIA card graphics, but I don't have Bumblebee installed to drive that, so it's disabled in the BIOS. I am using Nouveau as the graphics driver, as the NVIDIA binary blob has given me trouble.

I am finding some other people using Ubuntu and Debian and having the same issues with the Lenovo ThinkPad USB 3.0 Dock: Everything seems to work fine, but no displays are detected.

I checked xrandr, and that doesn't show the displays either.

I have increased the DisplayLink encrypted logging level and then plugged in the dock. If anyone from DisplayLink would like to see the log files, let me know.

Yeah, it seems to be related to a specific hardware combination, which I don't have. As long as the module is compiled and loaded, and the service running when the dock is plugged, means the rpm is doing things right. Hopefully someone at DisplayLink can provide more help (or someone else with the same hardware)

I had to sign the kernel mod with a private/public key pair to get it to run on my Lenovo because I dual boot with Windows 10 and it uses secure boot. I guess you could disable secure boot if that's easier.

Thanks for the info, good to know. I have secure boot disabled so didn't notice that was needed.

Enothen can you please update your RPM for F23 / 1.0.335

[enothen]

Awesome, didn't noticed the driver was updated this week. Yes, we'll do soon and post in here.

Any information on how you sign the driver? I'd like to keep SecureBoot enabled. Thank in advance.

I'm using fedora 24 workstation, which is currently running a 4.7 kernel. I reinstalled the package:

Complete!

But unfortunately it doesn' t work. The EVDI module cannot be compiled. It looks like I have an incompatible library that provides DRM functions. Anyone who has an idea how this can be fixed?
