Dell XPS 13 9350 + Dell 4-1 adapter

[ned83]

I bought this and it works on Windows.

But I can't get VGA/HDMI to work on Ubuntu 14.04 (that I've installed manually, originally this was a Windows machine).

I've tried to run the driver from here

can anyone help me to fix this, please?

[samjam]

it looks like the build system you have is not the one used to build your kernel.

Find what kernel package you have, and then try running:

apt-get update
apt-get upgrade
apt-get build-dep linux-image-3.19.0-59-generic # <-- (fix for your kernel version)

and then try again.

[ned83]

those instructions will downgrade my kernel version, right?

I can't do that because I need the one I have -> kernel 4.4.0-040400rc6-generic

otherwise the wifi won't work. I had to upgrade it from 4.3 (I think it was 4.3)

any other ideas?

[ned83]

I've just installed the new linux kernel, 4.6, released three days ago.

Still the same error..

[mlukaszek]

You don't have to downgrade. Install linux-headers package that matches the kernel you're using, so /lib/modules/$(uname -r)/build points to something which has headers :)

Cheers,
Michal

[ned83]

so I only need to do this?

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

and then try again to install the driver?

[mlukaszek]

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 I think you have the right headers installed already, but your compiler is a bit outdated:

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.

[ned83]

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

I have also the most recent GCC -> 4.9

If I try

sudo apt-get install gcc-4.9

I get

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?

[ned83]

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/466651/how-do-i-use-the-latest-gcc-on-ubuntu-14-04#581497

and then just execute

sudo ./displaylink-driver-1.1.62.run

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

The DE100 dongle works now :D

[ned83]

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!

[mlukaszek]

Can you grab the support logs? I wonder if you can be seeing this (http://www.displaylink.org/forum/showthread.php?t=64523).

I wasn't telling you to downgrade your kernel or even install a kernel,

This is the command I gave:

apt-get build-dep linux-image-3.19.0-59-generic # <-- (fix for your kernel version)

"build-dep" is to install the build-dependencies for whatever kernel you had installed.

But I see you got it working

[Vanadium]

Take a look at your kernel messages (dmesg). Perhaps you are also seeing

[10478.409066] [drm:drm_wait_vblank [drm]] *ERROR* Unsupported type value 0x40000bf, supported mask 0x7400003f
