Hello,

I can't compile the module.
here are the logs: https://pastebin.com/rKvuDbaT
As you can see I use gcc 13, do you think that could be the cause of these errors ?

Thanks in advance for your help !

After further research, It seems that the problem comes from the libdrm package which is not found by the installation script.

error: include/drm: entry file of the link editor not found: No file or folder of this type

Probable duplicated with this one

@maxime-bern @grinco Have you tried using the new standalone 5.7 driver?

Only Ubuntu is supported in an official manner, but I can assist you with some troubleshooting

@displaylink-emajewsk
make.log
I did. evdi fails to build (see log attached).

@displaylink-emajewsk

It's now succesfuly installing with the new driver !
But even after a reboot i can't use my USB dock.

How can i check if the driver is started ?
I can't find it with systemctl.

I have a free moment rn. Let me try installing tumbleweed

displaylink-driver service should start after plugging in the dock.

It's seems that evdi is not installed even after the installer say it's ok.

> modprobe evdi
modprobe: FATAL: Module evdi not found in directory /lib/modules/6.2.12-1-default

Yes. It is unable to find libdrm headers even though they're installed. I managed to reproduce (and fix) your issue on Tumbleweed but I'll elaborate on it later. Very short on time today. I believe the same thing happens in #412

Nice, thanx for the help !

Can confirm this version work: #412 (comment)
Using this change: #412 (comment)

@displaylink-emajewsk can you estimate when an official fix will be pushed ?

I have pushed the fix to the GitHub repository, but cannot be sure when the updated driver will be released.
