Dell XPS 13 9350 + Dell 4-1 adapter

so I only need to do this?

Code:

sudo apt-get install linux-headers-$(uname -r)

and then try again to install the driver?

OK, I read this more carefully. I think you have the right headers installed already, but your compiler is a bit outdated:

Code:

make[1]: Entering directory `/usr/src/linux-headers-4.4.0-040400rc6-generic'
Makefile:660: Cannot use CONFIG_CC_STACKPROTECTOR_STRONG: -fstack-protector-strong not supported by compiler

You probably need a newer gcc.
See similar problem for VirtualBox kernel modules - they also use DKMS.

I have the right headers, indeed (kernel 4.6.0-040600-generic )

I have also the most recent GCC -> 4.9

If I try

Code:

sudo apt-get install gcc-4.9

I get

Code:

gcc-4.9-base is already the newest version.

Looks like in the error log it's using gcc 4.8, I might need to update the alternatives, let me try that.

do I maybe need gcc 5?

I've managed!

I'm running Ubuntu 14.04, kernel 4.6 (just released a few days ago).

You need to be using gcc4.9. Even if you have it, it's not used by default.

Follow these steps

http://askubuntu.com/questions/46665...u-14-04#581497

and then just execute

Code:

sudo ./displaylink-driver-1.1.62.run

driver downloaded from here -> http://www.displaylink.com/downloads/ubuntu

The DE100 dongle works now

now, since I've done all these thing the system has became laggy, not responsive as it was before..

windows are dragging, gets to a point that I have to restart the machine.

Can it be something to do with the gcc ?

It also kicks me out of my session and makes me log in back in. Like if it's a reboot. Damn it!

Can you grab the support logs? I wonder if you can be seeing this.

Cheers,
