    Re: Ubuntu 15.10 on Dell Xps 15 9550 new Infinity display (i7 6gen 16gbr UHD 4k touch

    A small tip for anyone who wants to try out the newest nvidia-364 drivers on Ubuntu 16.04 (and maybe 15.10 too):

    uninstall nvidia-361 (or other currently installed version) first, otherwise nvidia versions will become mixed up, and you won't be able to log in anymore (at least that's what happened to me).

    Code:
    # switch to intel
    sudo prime-select intel
    <logout>
    <login>
    
    # uninstall 361
    sudo apt-get purge nvidia-361 libcuda1-361 nvidia-opencl-icd-361
    #may not be necessary, just to be sure
    sudo depmod -a
    
    # install nvidia-364
    sudo apt-get install nvidia-364
    On a sidenote: nvidia GPU now seems to be switched off automatically when activating intel graphics (Xenial).

    Just to share my experience with Wily, upgrading to Kernel 4.5 solved some issues:
    - Pluging in/out an HDMI projector/screen doesn't freeze the display anymore (X error). I am not using the NVidia chipset/driver.
    - The microphone now works properly
    - The Broadcom Wifi chipset seems to behave better: less errors in logs and less connection loss

    Yet, I still have some issues with:
    - The touchpad doesn't disable when I start typing
    - The Dell Docking station D3100: wired networking is alright, but external screen and sound is not. I managed to install the DisplayLink stuff with https://github.com/AdnanHodzic/displaylink-debian , sadly it doesn't work.
    - Some Fn keys raise errors and don't behave as expected: Session Lock (Esc), Keyboard backlighting (F10), Airplane mode (Print Screen).

    That doesn't look normal to me, especially if it happens every time after booting 15.10 and using it for a while. If you think it is caused by kernel 4.5, you can always revert to a previous kernel. 4.5 is pretty stable now, it may be something else. Try to check your root partition for errors like this (after saving all work):

    Code:
    sudo touch /forcefsck
    sudo reboot

    Background:

    I'm on XPS 15 9550 i5/1TB SSD SATA (I swapped in)/QHD - dual booting Linux Mint 17.3 and Windows 10

    Earlier in this thread, @bertusrex provided a .hcd he compiled. I copied to /lib/firmware/brcm, but then noticed this dmesg output

    Code:
    [    4.631773] EXT4-fs (sda5): re-mounted. Opts: errors=remount-ro
    [    4.744448] int3402 thermal: probe of INT3402:00 failed with error -22

    [    5.016368] Bluetooth: hci0: BCM: patch brcm/BCM2045A0-0a5c-6410.hcd not found
    So then I tried sudo cp BCM-0a5c-6410.hcd BCM2045A0-0a5c-6410.hcd - bluetooth works perfectly, but this kills the wifi somehow. I have to reload factory bios settings to get it to work again, then of course, my bluetooth is not working again. I tried the

    I tried the bcmwl-kernel-source_6.30.223.248+bdcom package in the driver manager, but my laptop just freezes attempting to apply and the broadcom option disappears from my driver manager.

    FYI For others:

    Other users: Linux mint 17.3 worked out of the box w/ the nouveau.modeset=0 trick others mentioned. Graphics were slow, but after install proper nvidia and intel drivers others mentioned, no problem. - graphics drivers can be found here: https://01.org/linuxgraphics/downloads/skylake-dmc-1.23. HDMI worked no issue. I ran into additional issues when i attempted upgrades to kernel 4.2 or 4.3, so I just kept the default 3.19. Still issues: headphone jack doesn't work and bluetooth issue mentioned above.
    Can you share me what ever firmware hcd file you have for this bluetooth BCM2045A0? I extract hcd from Windows 10 but it not work.
    I have this in my Lenovo Yoga 500. It work well under Windows and Hackintosh.
    I don't know how you make it work but this card require a slightly different method to uplaod firmware. I confirm it works on Hackintosh without upload firmware.

    Re: Ubuntu 15.10 on Dell Xps 15 9550 new Infinity display (i7 6gen 16gbr UHD 4k touch

    I may be wrong, but BCM20703A1 and BCM2045A0 seem to be different partnumbers for the same device. Depending on the firmware that's loaded, the device is called "BCM920703" or "BCM2045A0".

    This small archive I put together contains 3 hcd BT firmware files (*.422, *.473, *.481) All three are functional to drive the Broadcom BT module in the Dell DW1830 wireless card as far as I can tell.

    The 473 firmware seems to identify itself as BCM2045A0, despite the pid/vid being the same as before.

    To use a particular firmware file from this archive on Ubuntu 15.10/16.04, copy it to /lib/firmware/brcm:
    # example:
    Code:
    $ sudo cp BCM20703A1_001.001.005.0214.0481.hcd /lib/firmware/brcm/BCM-0a5c-6410.hcd
    (destination filename might be /lib/firmware/brcm/BCM2045A0-0a5c-6410.hcd for Linux Mint 17.3, look in dmesg for filename)

    then make sure the permissions are OK afterwards, e.g.:
    Code:
    $ ls -l /lib/firmware/brcm/BCM-0a5c-6410.hcd
    -rw-r--r-- 1 root root 54734 apr  6 09:39 /lib/firmware/brcm/BCM-0a5c-6410.hcd
    It might take TWO reboots for the new firmware to work succesfully. If you still have problems after two reboots (e.g. BT or wifi not working) try resetting the bios to factory defaults.

    Code:
    File:                                    Identifies as*)          Works on XPS 15 9550 with DW1830

    my prob is that the firmware loads but in fact it not works.
    thank you, I'll try your hcd now.

    Re: Ubuntu 15.10 on Dell Xps 15 9550 new Infinity display (i7 6gen 16gbr UHD 4k touch

    Here is my log for a successful install of Linux Mint 17.3 (based on Ubuntu 14.04) on a Dell XPS 9550 (i7-6700HQ, 16GB, UHD 4k touch, 1TB Samsung NVMe SSD, GTX960M Dell Wireless 1830, 84W).

    This guide by Javier was great. The fresh machine had an A05 BIOS, I upgrade to A06 via the default Windows 10. Next I used sysrescuecd (with the isohybrid command before writing to the USB stick) to image the 1TB disk. Next I used Window's Partition tool to shrink Windows to 60GB, first I had to disable Virtual Memory and turn off System Restore (otherwise it said the disk couldn't be shrunk by much).

    After this I could boot with the Linux Mint 17.3 live desktop. Via the installer I added a 36GB swap partition (not sure if it is necessary but I figured it wouldn't hurt) and the rest was formatted as root (/) as ext4. The installation went smoothly, I opted to encrypt /home. My 2G wifi router was identified (I still don't have 5G).

    The tiny fonts on the Mint desktop were hard work so "Preferences | General | Desktop Scaling | Normal->HiDPI". Nvidia was setup using the Driver Manager with 352.63. Kernel 3.19.0.32 was installed, 3.19.0.58 worked too. Swapping between Nvidia and Intel graphics was fine. Sound works fine. I didn't try Bluetooth.

    I tried kernel's 4.2.0.35 and 4.4.0.18 but the system wouldn't boot (it stopped after a few lines of post-GRUB text, hung, then dropped to busybox), I've stuck with 3.19.0.58.

    Suspend seems to work (I've tried several in a row inbetween boots, no problems yet).

    Some problems:
    • Some GUI elements don't work so well with HiDPI (e.g. fixed size windows)
    • Powertop v2.5 only shows the C states POLL, C1, C2, C3 (I was expecting lots more, I guess this is a 3.19 kernel issue)
    • Powertop shows 27W at idle (no browser, wifi on, screen bright) 3hr projected life (this is probably lower compared to a newer 4.x kernel)
    • I've not added any proprietary firmware for the wifi
    • GRUB has slow keyboard response - using the down arrow takes approx 1/2 second per press - does anyone know how to solve this?
    • Using the nvidia control panel I can swap between nvidia and the Intel driver, after a logout with Intel Powertop reports 10W and 8 hours


    I tried a live CD for Ubuntu 16.04beta2 and note that Powertop (v2.8) reports more states (C2, C3, C6, C7, C8, C9, C10), also both 2G+5G wifi worked immediately and on the nouveau driver Powertop reported 16W of power (fairly bright screen, wifi on, Firefox open).

    Probably the next sensible step is to wait for a couple of weeks until Linux Mint 18 is available and then I expect to reinstall. The machine seems to be working fine, I'll log any other problems in this post.

    Update - I'm now running 4.4.0-22-generic and I'm still with Linux Mint 17.3. After switching to the new kernel the boot no longer works but the edit with nvme noted here was all that was needed. I'm using the Intel GPU at present, I've been working for 4 hours and I still have plenty of battery. I've also Suspended once this session without a problem. The Intel GPU has screen glitches on occasion (an alt-tab away and back clears them), I'm not using any boot switches. Powertop 2.5 reports more power states with this kernel than before (C1E-SKL, C3-SKL, C7s-SKL, C8-SKL, C9-SKL, C10-SKL, RC6pp).

    Update - for Windows 10 the dual-boot was unstable, I wasn't using at first, in the last few weeks I tried (to install the new Doom and had BSODs every 30 minutes. It turns out the Microsoft AHCI drivers don't like AHCI mode. The Samsung 950 Pro driver linked by Nekobai was the answer. I'd already used Windows Update and Dell Update to update all my drivers and that hadn't helped. With the Samsung 950 Pro driver I'm happily playing Doom.

    Update - I've replaced the stock 16GB with Crucial 32GB DDR4-2400 and it works just fine.

    Update - Now I'm trialling kernel 4.7.0-generic on Mint 18 (4.4.0 worked fine on Mint 18 too). powertop 2.8 reports *either* PC2/PC3 if I use the nvidia driver (361.42) or PC2-PC8 (much much better!) if I switched to nouveau (1:1.0.12), I'm sticking with the nouveau driver as I stick to the Intel GPU in Linux anyhow (I only use the nvidia GPU in Windows for Doom). The difference between the two is - using Intel GPU with nvidia driver installed powertop reports 25W, using Intel GPU with nouveau driver installed powertop reports 16W.
