modprobe: ERROR: could not insert 'evdi': Invalid argument

This is the same problem I'm having. The module builds fine, but insmod / modprobe fails to load it with these messages. This is on Ubuntu wily, kernel 4.2.0-34-generic, with latest intel drivers installed.

OK,

What are the Intel drivers that you're using exactly? Are they open sourced or binary? I don't see why this could happen if they were also compiled on your machine with the same version of drm... Unless I'm missing something.

Cheers,
Michal

Not sure. The installer hides much from the user, but it appears to install a different version of libdrm and then installs an i915 driver (it seems to put source for this driver in /usr/src and install via dkms)

I might try installing via the source tarball instead of the Ubuntu installer to see if it changes anything.

dkms autoinstall does not fix for me either

Verifying archive integrity... All good.

The computer I'm trying to get it working on is a NUC - not sure if that matters.

I might have the same problem

is there a workaround that doesn't break the intel installation and allows displaylink service to run?

unfulvio · 04-03-2016, 12:59 PM

never mind, there was no other solution for me than to remove Intel drivers and then displaylink would install

however this was a bit of a bummer -- intel drivers did provide a bit of enhancement for power management and now that I reverted to vanilla ubuntu drivers, an old Chrome bug creeped out again (basically I had to disable GPU acceleration there)

ideally, I wish Displaylink worked with native vendor drivers too

Same thing here. Not working with i915 intel drivers on a NUC. Installing displaylink off of a live usb of ubuntu (without the intel drivers added) worked fine.
