XPS13 9350 skylake no wifi on Ubuntu 15.10
With Ubuntu 15.10 (default kernel 4.2), 9350 almost works out of box, except this DW1820A wireless card. It has been a few days, I still couldn't get the wireless card working. From what I have read on Linux Wireless, BCM4350 driver is queued to be included in kernel 4.4. That's a long wait.
Could anyone help?

yes I was able to compile and use 4.4rc3 but it does not work as well as my 4.3 custom kernel.
If you like I can send you my .deb packages for the kernel

If you could just shortly explain how you compile & package the kernel that would be more helpful, that way I can just compile and patch kernel myself :)

If you had already compiled a 4.3-custom with the instructions at the beginning of this thread, with the latest linus' kernel tree, it's just a matter of copying the attached .config and moving it to /usr/src/linux and then running:
make -j `getconf _NPROCESSORS_ONLN` deb-pkg LOCALVERSION=-custom
... the .deb will be in /usr/src
But I'm not getting the password prompt for LUKS on boot, so someome with LUKS would have to test this.

easiest fix is $10 usb wifi adapter. my experience with ralink and realtek chipset models is that you plug them in and they work.

This particular model also works with Raspberry PI and windows 8 or 10 out of the box.

Can anyone able to git clone linus' 4.4rc5 tree, compile and boot it on Ubuntu 15.10 post their .config file and their procedure?
All I get is a black screen after grub now, with or without the i915.preliminary_hw_support grub argument. And so I'm stuck on 4.3 that crashes when plugging a 4k monitor.
Cheers!

Interesting idea, but I just tested and it didn't work (4.4.0-rc5)...
Can you post your .config so I can check if anything differs?
Cheers!

No sure which config file you need...
But here's what is did to get wifi working:
1> install Kbuntu 15.10 with AHCI mode and reboot. 2> install 4.4 rc5 kernel from Ubuntu mainline kernel build. 3> put the brcmfmac4350-pcie.bin into /lib/firmware/ 3> add nvme module for kernel 4.4 rc5. 4> reboot
hope this help
btw, mine is i5, 8GB ram, 256GB pcie ssd, FHD, xps13

You should replace the uname -r with an actual kernel version, otherwise you'll replace the modules for the current kernel (which probaly works), you could also use -all to do this for all kernels

oh, I meant the /usr/src/linux/.config file that you use to configure a kernel when you build it yourself, but I just realized you are instead using Ubuntu's kernels, I'm guessing from here:
kernel.ubuntu.com/~kernel-ppa/mainline/v4.4-rc5-wily/
So ok, I'll try that and see if that can finally boot and, hopefully, help with plugging in a 4k monitor, the only thing left that is not working, cheers! :)
EDIT: Ok, so i only managed to boot a 4.4 from the drm-intel-nightly builds, but I still get the crash from the monitor, I'll start a new thread for it since it's not Wi-Fi related at this point... But for the recap, when logging in, the P2715Q fall asleep for no reason, making the laptop think it disconnected and radjust it's monitor mode which crashes everything...

I haven't had much success getting any of the newest kernels to boot. I've tried a couple 4.4rc and also the 4.4 intel-drm nightly. In both cases I've tried to load nvme modules and add some of the intel graphics kernel params.
Right now I'm on an older nightly of 4.3 intel drm and it's working decently, but things like the audio patch and a couple other things are not included here.
Does anyone have some reproducible steps they can share to get 4.4 working?
Also any news on the bios update that was supposed to drop mid-December that is supposed to feature some improvements to performance and battery life?

So, you can download the file here: https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux-firmware/plain/brcm/brcmfmac4350-pcie.bin?h=xenial&id=6f11197c91243ddeb529ff1c6f245ae9aaf82e39
This files needs to be in /lib/firmware/brcm/ (sudo cp ./ /lib/firmware/brcm/)
3.
$ sudo vi /etc/initramfs-tools/modules
Add:
i915
nvme
$ sudo update-initramfs -u -k all
you can replace all with the exact kernel wich should be something like this 4.4.0-040400rc5
4. Reboot

Sorry, I thought the post I was replying to (the one just before mine) would be quoted.
I have the QHD+, i7, brcm wifi, and I was referring to kernel 4.4rc5.
With that parameter I finally got a working 4.4 kernel.
I just connected to my Dell U2515H with a Type C to HDMI Adapter, works flawlessly (both screens etc).

Disregard the kernel version part. That was copy pasta from a previous post I made.

Hadn't tried suspend yet, and... it just crashed when trying to suspend.
Will have to look into this.
