XPS13 9350 skylake no wifi on Ubuntu 15.10

I've applied patch from 4.4 kernel for Broadcom 4350 support, also got the latest firmware, and it works. check that wiki.archlinux.org/.../Dell_XPS_13_(2016)

I am on Arch Linux with 4.2.5 (4.3 is not working properly yes), looks like everything is ok, except battery live (deep sleep C-states are not available, waiting for 4.3 for the support) and random hangs. or may be I should migrate to Windows :emotion-5: 

mpalmiotto and others :

Have you by any chance been able to use virtualbox with that custom kernel?

It doesn't seem to be able to compile the kernel driver against it...

cheers! :)

Works fine, 

ᐅ lsmod | grep vbox
vboxpci                24576  0
vboxnetflt             28672  0
vboxnetadp             28672  0
vboxdrv               385024  4 vboxnetadp,vboxnetflt,vboxpci

installed packages virtualbox and virtualbox-host-dkms

I've been using virtualbox and vagrant with kernel 4.3~something (have detailed in prior post). It's NOT a "custom" kernel that I compiled myself though (swapped out the broadcom for an intel so it's not needed).

Yeah, between this and displaylink not working, it looks like the best solution is to just get the intel card.

skyred I can get in GRUB advanced boot options for Ubuntu. That's no problem. The problem is that under advanced options I don't see the custom kernel I compiled, following the previous instructions.  I installed my custom kernel twice via dpkg. I don't see any error messages. But, still don't see the option to boot the custom kernel. I had the same issue, no initrd being generated or placed in /boot. The following worked perfectly for me and I saw dpkg generate the initrd and place it in /boot appropriately. $ cd ~ $ wget en.community.dell.com/.../brcmfmac4350_2D00_pcie.zip $ unzip brcmfmac4350_2D00_pcie.zip $ sudo mv brcmfmac4350-pcie.bin /lib/firmware/brcm/ $ sudo chmod 600 /lib/firmware/brcm/brcmfmac4350-pcie.bin $ sudo apt-get install git build-essential kernel-package fakeroot libncurses5-dev libssl-dev ccache $ git clone git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next.git $ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git $ cd net-next $ git format-patch -1 e3c92cb $ cp 0001-brcmfmac-Add-support-for-the-BCM4350-PCIE-device.patch ../linux/ $ cd ../linux $ git fetch git://git.launchpad.net/~ubuntu-kernel-test/ubuntu/+source/linux/+git/mainline-crack cod/tip/drm-intel-nightly/2015-11-05 $ git checkout FETCH_HEAD $ git am --reject 0001-brcmfmac-Add-support-for-the-BCM4350-PCIE-device.patch $ cp /boot/config-`uname -r` .config $ make oldconfig $ yes '' | make oldconfig $ make clean $ cd ../ $ git clone git://kernel.ubuntu.com/ubuntu/ubuntu-wily.git $ cp -a /usr/share/kernel-package ubuntu-package $ cp ubuntu-wily/debian/control-scripts/{postinst,postrm,preinst,prerm} ubuntu-package/pkg/image/ $ cp ubuntu-wily/debian/control-scripts/headers-postinst ubuntu-package/pkg/headers/ $ cd linux $ CONCURRENCY_LEVEL=`getconf _NPROCESSORS_ONLN` fakeroot make-kpkg --initrd --append-to-version=-custom --overlay-dir=$HOME/ubuntu-package kernel_image kernel_headers $ cd ../ $ sudo dpkg -i linux-image-4.3.0-custom-dbg_4.3.0-custom-1_amd64.deb $ sudo dpkg -i linux-headers-4.3.0-custom_4.3.0-custom-1_amd64.deb

I followed this new instruction, but I still cannot boot into 4.3 custom kernel.

Wifi is working like a charm with those instructions, thanks a lot.

I then tried to get dislaylink to work as well, which I managed to compile, but then the module wont insert:

I noticed that the x64 folder in the displaylink-folder is empty, and only the x86 contains a lievdi.so etc.
Did I do anything wrong, or is that simply something that wont work? ;)

Also tried that, the DLM service cannot be started because the module is wrong:

Nov 19 11:12:57 rocket modprobe[2556]: modprobe: ERROR: could not insert 'evdi': Exec format error

Must have something to do with the custom kernel for the Wifi, I assume... Will keep trying.

You may be right as I have replaced the Broadcom WIFI card with the Intel WIFI card.

I tried again. This time, I upgraded Ubuntu 15.10 kernel to 4.3 first, then followed the instruction, I was able to create and boot into 4.3-custom kernel, and WIFI works well now. Finally.

Then, I was trying to pair my Razor Orochi 2015 to my XPS13 Skylake. The bluetooth UI was able to recognize the mouse, but it couldn't pair with it. Then, I tried to pair my Nexus 5 or 6P to XPS13. XPS13 Couldn't even recognize them.

Then, in command line, I typed:

dmesg | grep -i blue

I see:

bluetooth hci0: Direct firmware load for brcm/BCM-0a5c-6412.hcd failed with error -2

hmm. Does this have something to do with the patch we did early in the wireless driver?

I got Bluetooth working perfectly by following the appropriate instructions for the 9343 from here :http://forthescience.org/blog/tag/xps13.html

Only thing left for me is the displaylink story (and I havent played with suspend/resume at all yet).

This works:

Very helpful, works for me !

Thank you.

Can you please confirm that the instructions to get Bluetooth working for 9340 will also fix the Bluetooth on 9350?
