I first tried to keep a dual-boot just in case, but once we disable Raid and put SATA in AHCI mode, Windows can't boot anymore. (later I read it could be possible to fix it by rebooting several times Windows till safe mode is kicked in, but it was too late for me.)
Just in case again, one can boot Windows and create a USB recovery.
- Secure Boot: disable
- SATA: switch from Raid to AHCI
- Boot: not sure it's needed but I disabled Windows boot manager entry and kept the hdd UEFI entry: UEFI: PM951 NVMe SAMSUNG 1024GB, Partition 1
- auto os recovery threshold off
To update the BIOS:
- put it on a USB stick
- select BIOS flash update on the boot screen (F12).
No need to put it on a bootable DOS, just give the exe to the BIOS update built-in util.
You can even drop the update on /boot/efi as it's also a FAT partition, no need for a USB memory stick.

Attention: with versions 1.2.10 through 1.2.16 and older Linux kernels, there is a serious bug that let the screen black after suspend/wake up. The workaround is to set the lightness to the maximum but it breaks further lightness tuning.
Linux kernels 4.8 and below tend to work best with A6 BIOS (1.2.0), although there is a workaround that allows it to work with later versions. This workaround uses the intel_reg utility to reset the "pwm_granuality" setting of the onboard graphics. Solution discussed here: . This issue is reportedly fixed in Linux 4.9, and also in recent Ubuntu 16.10 kernel updates. See the patch here .
Even with the intel_reg workaround above, the screen brightness cannot be set to the lowest level without turning the screen off. This is fixed in 1.2.18.
I kept UEFI so we need a Debian netinstall because liveCD doesn't have UEFI support yet.
But Wi-Fi requires a proprietary firmware:
so the easiest is to take a Debian netinstall with proprietary firmwares included.
At time of writing Stretch is testing and last release is alpha5:
dd the image on a USB stick and boot it.
It will also complain for a missing brcmfmac43602-pcie.txt but we can safely ignore it. (well I think so, but Wi-Fi has troubles now and then under heavy load, see below)
I chose a guided partitionning of the entire disk, with encrypted LVM containing /, /home and swap. But proposed / was a bit too small IMHO (10G) so I deleted and recreated / (50G) and /home.
Initially I tried to add the "discard" option for the partitions which should help on SSD but the kernel reported that "discard" wasn't supported by the disk.
If you want to backup partition table and partitions before destroying everything, it's the right time!
parted /dev/nvme0n1 print sgdisk --backup=/some/safe/location/nvme0n1.gpt /dev/nvme0n1
I installed Cinnamon. I don't know for the others but Cinnamon has a nice auto setting to double features on HiDPI screens.
Once installed, the Debian didn't boot up.
I tried many things but at the end the only thing that worked was to copy Debian EFI to the default one:
Starting the netinstall again, in rescue mode, get a chroot shell, then
mount /dev/nvme0n1p1 /boot/efi cd /boot/efi/EFI mkdir boot cp debian/grubx64.efi boot/bootx64.efi
I also deleted the Windows files in EFI.
FTR things that failed included:
- Refind couldn't boot at all. Strange as the netinstall could boot...
- tweaks with efibootmgr, update-grub etc
UPDATE: It might be possible to fix the issue from the BIOS itself, see http://www.dell.com/support/article/us/en/04/SLN297060/en
- Keyboard backlight and media buttons (volume, luminosity, backlight)
- Wi-Fi (with the proprietary driver, cf installation above)
- SD-Card reader
- Speakers, mic
Working after manual steps
Screen was working but dmesg was complaining:
i915 0000:00:02.0: firmware: failed to load i915/skl_dmc_ver1.bin
So I installed that firmware, not sure what it's changed
sudo apt-get install firmware-misc-nonfree
apt-get install bumblebee-nvidia reboot
apt-get install nvidia-settings optirun -b none nvidia-settings -c :8
This also works for CUDA:
optirun -b none ./cudaHashcat64.bin -m 500 example500.hash example.dict
Nothing wrong with the touchpad but its default config is a bit painful especially because it's large and my right palm touches it often, even with the option to diable it when typing and because it's "soft" buttons.
I disabled the button area to limit somehow the problem but still you've to get used to first touch and hold before pressing a button to do a drag and drop and not the opposite.
To add a middle button:
synclient RightButtonAreaLeft=3914 synclient RightButtonAreaRight=0 synclient RightButtonAreaTop=4026 synclient RightButtonAreaBottom=0 synclient MiddleButtonAreaLeft=3100 synclient MiddleButtonAreaRight=3873 synclient MiddleButtonAreaTop=4026 synclient MiddleButtonAreaBottom=0
And because I love it:
If with some kernels you get troubles using Synaptics options, check dmesg, maybe Touchpad is detected by another driver too:
DLL06E4:01 06CB:7A13 Touchpad as /devices/pci0000:00/0000:00:15.1/i2c_designware.1/i2c-7/i2c-DLL06E4:01/0018:06CB:7A13.0003/input/input14 hid-multitouch 0018:06CB:7A13.0003: input,hidraw2: I2C HID v1.00 Mouse [DLL06E4:01 06CB:7A13] on i2c-DLL06E4:01
If this is so, add /etc/modprobe.d/synaptics.conf with this line, cf Kernel section below:
Touchscreen works well but when an external screen is connected, it spans over both screens so e.g. touching the middle of the laptop screen moves the mouse to some middle point of the virtual screen combining both screens.
To fix it, see https://wiki.archlinux.org/index.php/Calibrating_Touchscreen
This example is for an external screen mapped to the right of the laptop screen:
# c0 = width of laptop screen / total width c0=$(bc -l <<< "scale=2; $(xrandr|grep -A1 eDP1|sed '1d;s/x.*//')/$(xrandr|grep '^Screen 0'|sed 's/.*current //;s/ x.*//')") xinput set-prop "ELAN Touchscreen" --type=float "Coordinate Transformation Matrix" \ c0 0 0 \ 0 1 0 \ 0 0 1
Kernel complains about a missing file.
Apparently we can get it from Windows drivers but I don't know where to find them, so I took this one and copied it into /lib/firmware/brcm
Then Bluetooth was recognized but I couldn't pair my WM615 mouse.
After restarting the Bt adaptor, I could finally pair:
bluetoothctl power off power on
There is also a possibility to pair directly from bluetoothctl, see https://wiki.archlinux.org/index.php/bluetooth#Bluetoothctl
I finally changed the Wi-Fi+BT card for an Intel one, see #Hardware_changes
Cinnamon handles it nicely but some applications don't such as Gimp and you end up with a microscopic tools ribbon.
See https://wiki.archlinux.org/index.php/HiDPI for some useful tips
xdpyinfo | grep -B2 resolution screen #0: dimensions: 3840x2160 pixels (1016x572 millimeters) resolution: 96x96 dots per inch
I've no ruler at hand but if it's 15.6 in diagonal and pixels are square, this gives 293.4 dpi for screen dimensions of 332x187mm.
So closest hit with common DPI is 96*3=288dpi
xrandr --dpi 288 xdpyinfo | grep -B2 resolution screen #0: dimensions: 3840x2160 pixels (338x190 millimeters) resolution: 289x289 dots per inch
Let's document those fictive dimensions for next boots by creating /etc/X11/xorg.conf.d/90-monitor.conf with
Section "Monitor" Identifier "<default monitor>" DisplaySize 338 190 # In millimeters EndSection
QT5 and GTK+ 3
To enable better scaling of QT5 and GTK+ 3, add to .bashrc (not to .xsessionrc otherwise Cinnamon taskbar is messed up!):
QT_DEVICE_PIXEL_RATIO=3 GDK_SCALE=3 GDK_DPI_SCALE=0.4
sudo apt-get install qt4-qtconfig qtconfig-qt4
=> one can change font size
E.g. copy /usr/share/gimp/2.0/themes/Default as ~/.gimp-2.8/themes/HiDPI and change a few options:
--- gtkrc +++ gtkrc - GimpToolPalette::tool-icon-size = button + GimpToolPalette::tool-icon-size = dialog - GimpEditor::button-icon-size = menu + GimpEditor::button-icon-size = button
Change "dpi" in "Graphics" tab
View/Scale Factor is helpful...
Chrome works fine but Chromium broke at some point, so I've to launch it with:
GDK_SCALE=2 exec chromium
Small console font:
I don't care but if that's an issue for you, from here:
sudo dpkg-reconfigure console-setup
- Choose UTF-8
- Choose the default Combined - Latin, ... option ("Latin" includes the English alphabet)
- Select the terminus font
- Select 16x32
To apply immediately, open a TTY and run setupcon, else just reboot
Combining HiDPI screen with external non-HiDPI? See https://wiki.archlinux.org/index.php/HiDPI#Multiple_displays
apt-get install lm-sensors sensors-detect
Sensors-detect found coretemp which is now loaded via /etc/modules:
The sole jack is a TRRS, combining output and mic.
Soundcard is a Realtek ALC3266
grep -r Realtek /proc/asound/card* /proc/asound/card0/codec#0:Codec: Realtek ALC3266
With Debian+Cinnamon, the system detects the mic, we can see it in the sound properties and select it, but still the internal mic is used.
When using pavucontrol, selecting the "headset microphone" works fine (it still needs some level boosting).
DA200 used to be recognized only if it was plugged at boot.
With kernel 4.6 the device is properly detected dynamically.
The adapter is actually using DisplayPort.
VGA output works.
HDMI output is limited to some modes (max 1920x1080, cf Dell support) and by default xrandr will try an unsupported mode.
Even "xrandr --output DP-1 --mode 1920x1080" fails by default.
Some supported modes: 800x600, 1024x768, 1280x720, 1920x1080i
1920x1080i is interlaced and awful to look at.
Reducing the rate allows a non-interlaced 1920x1080 mode, you can test it with:
xrandr --output DP-1 --mode 1920x1080 -r 30
If this works for you, you can create a new mode, using cvt to find the proper parameters:
cvt 1920 1080 30 # 1920x1080 29.95 Hz (CVT) hsync: 33.01 kHz; pclk: 79.75 MHz Modeline "1920x1080_30.00" 79.75 1920 1976 2168 2416 1080 1083 1088 1102 -hsync +vsync
Creating and adding the new mode:
xrandr --newmode "1920x1080_30.00" 79.75 1920 1976 2168 2416 1080 1083 1088 1102 -hsync +vsync xrandr --addmode DP-1 "1920x1080_30.00"
Now you can choose this new mode:
xrandr --output DP-1 --mode "1920x1080_30.00"
When plugged the following hardware gets detected:

i915 and blank screen
There were numerous issues with the video card. Now with latest kernels (>=4.8) most issues are gone, still some occasional blank screen or freeze when plugging an external HDMI.
WM615 mouse used to act erratically, the cursor stopping now and then. Now with latest kernels and an Intel Wi-Fi+BT card it's fine.
Wi-Fi tends to disassociate under heavy load, switching to other SSIDs or frequencies (5Ghz<>2.4GHz) and coming back seems to help.
I finally changed the Wi-Fi+BT card for an Intel one, see #Hardware_changes
Rfkill button of the keyboard (Fn+PrtScr) doesn't seem to work, no big deal.
initramfs complains about lvmetad and I'm not sure it's that useful on SSD, so just disabling it:
Then stop it
systemctl stop lvm2-lvmetad
Debian kernel 4.8 works quite well
Warning, to compile >=4.4, one needs at least initramfs-tools v0.122 to get the nvme.ko properly loaded and therefore the SSD properly seen.
To compile a vanilla kernel, cf http://www.cyberciti.biz/faq/debian-ubuntu-building-installing-a-custom-linux-kernel/

Replacing Broadcom Wi-Fi+BT by an Intel one:
- Intel 7265 Dual Band Wireless-AC 7265NGW Card 802.11ac 867Mbps WIFI BT4.0 UK
- This requires installing package firmware-iwlwifi
- Seems to have less Wi-Fi issues, but still the same BT problems pairing the Dell mouse
Alternatives to DA200:
- HDMI Male To VGA Female Converter
- USB 3.0 10/100/1000Mbps Gigabit Ethernet RJ45
- 4-Port Ultra-Slim USB 3.0 Hub
