Custom RPM created for Fedora and others

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.

[enothen]

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:

# dnf reinstall displaylink-1.0.335-1.x86_64.rpm

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?

The evdi module included in this package does not support 4.7.x or greater series kernels. You will have to build evdi and libevdi from source, or wait for an updated package.

[MartinHerrman]

Thanks! After installing libdrm-devel I could compile the latest code which I downloaded from the GIT repository. I copied the module to the /lib/modules/kernel/misc directory and ran depmod. Finally I reinstalled the displaylink rpm.

Will test the result tomorrow at work!
