===== How to get into BIOS =====

Power off, press and hold the volume up key, press power button, release volume key when surface logo appears.

===== Kernel less 4.16 =====

Linux seems to get stuck in sleep on kernels less than 4.16. A workaround is to replace the sleep function with hibernate so that when you put your device to sleep it hibernates instead.

<code>
sudo ln -s /usr/lib/systemd/system/hibernate.target /etc/systemd/system/suspend.target
sudo ln -s /usr/lib/systemd/system/systemd-hibernate.service /etc/systemd/system/systemd-suspend.service
</code>


===== Substitute Suspend with Freeze =====

Surface Pro 3 does not support suspend-to-RAM (not even in Windows). The "Connected Standby", "modern" standby or active idle (S0i1/S0i3 states) is not implemented in Linux, but there is "freeze" state which is at least something and may help conserve battery somewhat compared to leaving the machine running.

<code>sudo vi /etc/systemd/sleep.conf</code>
<code>
[Sleep]
SuspendState=freeze
</code>


===== Wifi crashes =====
Wifi crashes
<code>sudo vi /etc/NetworkManager/dispatcher.d/no-power-save</code>
<code>
#!/bin/sh

# MDJ
IFACE=$1
ACTION=$2

IW=/sbin/iw

test -x $IW || exit 0
[ "$IFACE" = "wlp1s0" ] || exit 0

case "$ACTION" in
    up)
        $IW dev $IFACE set power_save off
        ;;
esac
</code>
<code>sudo chmod 755 /etc/NetworkManager/dispatcher.d/no-power-save</code>

<code>sudo vi /etc/NetworkManager/NetworkManager.conf</code>
<code>
[connection]
wifi.powersafe=2 # 2=disable
wifi.mac-address-randomization=1 # 1=disable
wifi.cloned-mac-address=permanent

[device]
wifi.scan-rand-mac-address=no
</code>
===== Wifi sleep =====

Wifi slow not not coming back after sleep:

Turn off or enable wifi power savings:
<code>
cat /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
[connection]
# 2 = powersave disabled, 3 = powersave enabled
wifi.powersave = 2

sudo systemctl restart NetworkManager
</code>

OR


A systemd script which reloads the mwiflex WiFi kernel module of the Surface Pro 3 when resuming from suspend:
<code - /lib/systemd/system-sleep/wifi-reset>
#!/bin/sh

# NAME: /lib/systemd/system-sleep/wifi-reset
# DESC: Resets WiFi which can be flakey after a long suspend.

MYNAME=$0

restart_wifi() {
    /usr/bin/logger $MYNAME 'restart_wifi BEGIN'
    /sbin/modprobe -v -r mwifiex_pcie # This removes mwifiex too
    /sbin/modprobe -v mwifiex
    /sbin/modprobe -v mwifiex_pcie
#    systemctl restart NetworkManager.service
    /usr/bin/logger 'systemctl restart NetworkManager.service (SUPPRESSED)'
    /usr/bin/logger $MYNAME 'restart_wifi END'
}

/usr/bin/logger $MYNAME 'case=[' ${1}' ]'
case "${1}/${2}" in
    hibernate|suspend|pre*)
      ;;
    resume|thaw|post*)
      restart_wifi;;
esac
</code>

NOTE: Sometimes simply resetting network manager is all that is needed. In that case un-comment the line above by removing #. Then comment out the two lines above it by putting # at the beginning of those two lines.

You'll need to create this script, called wifi-reset, with sudo powers and save it into the directory /lib/systemd/system-sleep. Then mark it executable using:

<code>
chmod a+x /lib/systemd/system-sleep/wifi-reset
</code>


OR

Try to go into sleep mode, start the computer up and do
<code>
sudo nmcli radio wifi on
</code>
if your computer connects to the correct wifi, then this might be a optional solution for you. your computer should auto-connect to your saved wi-fi access point.

Switch wifi off and on again using a script:
Create a script
<code>
sudo vi /usr/lib/pm-utils/sleep.d/wakewifi
</code>
content:
<code>
#!/bin/sh
    case "$1" in
        resume)
            nmcli radio wifi on
    esac
</code>
Make it executable.
<code>
sudo chmod a+x /usr/lib/pm-utils/sleep.d/wakewifi
</code>



Disable power management of network interface:
Another approach is to add an explicit directive (wireless-power) to control power management in the /etc/network/interfaces configuration file (e.g. Disable it for wlan0 with DHCP):
<code>
    auto wlan0 
    iface wlan0 inet dhcp
    wireless-power off
</code>


Wifi Resume service:
Test if the following command works
<code>
sudo systemctl restart network-manager.service
</code>

If this works, you can create a script to automate it.
<code>
sudo vi /etc/systemd/system/wifi-resume.service
</code>
<code>
#/etc/systemd/system/wifi-resume.service
#sudo systemctl enable wifi-resume.service
[Unit]
Description=Restart networkmanager at resume
After=suspend.target
After=hibernate.target
After=hybrid-sleep.target

[Service]
Type=oneshot
ExecStart=/bin/systemctl restart network-manager.service

[Install]
WantedBy=suspend.target
WantedBy=hibernate.target
WantedBy=hybrid-sleep.target
</code>
Activate it with
<code>sudo systemctl enable wifi-resume.service</code>

Module option available to prevent deep sleep:
<code>
$ grep 'MWIFIEX' /var/log/dmesg
[   31.679019] kernel: mwifiex_pcie 0000:01:00.0: info: MWIFIEX VERSION: mwifiex 1.0 (15.68.19.p21) 
$ modinfo mwifiex | egrep 'desc|sleep'
description:    Marvell WiFi-Ex Driver version 1.0
parm:           disable_auto_ds:deepsleep enabled=0(default), deepsleep disabled=1 (bool)
$ sudo vi /etc/modprobe.d/mwifiex.conf
options mwifiex disable_auto_ds=1
$ sudo systemctl restart NetworkManager

$ iwconfig wlp1s0 | grep "Power Management"
</code>

Disable Lid-Wake if you find lid-events to cause sleep issues.
    sudo gedit /etc/UPower/UPower.conf
    and change IgnoreLid=false to IgnoreLid=true


add applet: battery applet with monitoring and shutdown (bams)
https://cinnamon-spices.linuxmint.com/applets/view/255
requirements:
sudo apt-get install zenity sox libsox-fmt-mp3

#wifi disconnect issues requiring full reboot to get wifi working again:
sudo vi /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
#disable wifi powersave using:
wifi.powersave = 2
alternative (older version?):
iwconfig mlan0 power off
and you should see Power Management:off when you type iwconfig. To get it automatically, save this script in /etc/pm/power.d/wireless:
#!/bin/sh
/sbin/iwconfig mlan0 power off


Screen saver
It works but the screen is not off which heats and consumes energy. If you want it really off do:

xset +dpms
xset dpms 300

300 being seconds, it turns off the screen after 5 minutes. It can be put in Xorg configuration by adding a file in /etc/X11/xorg.conf.d with:

Section "Monitor"
  Identifier "Monitor0"
  Option "DPMS" "true"
EndSection

Section "ServerLayout"
  Identifier "ServerLayout0"
  Option "OffTime" "5"
EndSection

I must confess it is not a perfect success since sometime it does turn off the backlight, sometime it does not...

wifi drivers:
1. Open a Terminal and install Git via sudo apt-get install git 
2. Download the drivers from the Git repository, to do so, run:
git clone git://git.marvell.com/mwifiex-firmware.git  
mkdir -p /lib/firmware/mrvl/  
cp mwifiex-firmware/mrvl/* /lib/firmware/mrvl/
</code>

===== Firmware updates =====

https://github.com/linux-surface/surface-firmware-old

===== FN Function Keys =====

By default the F1-F12 keys on the Surface Pro 3 need to be accessed using the FN key and the media keys are the default state.

To lock the FN key, so that the F1-12 keys work directly, press ''FN + CAPS LOCK''

===== Custom Surface Kernel =====

https://github.com/linux-surface/linux-surface/wiki/Installation-and-Setup

Debian / Ubuntu
<code>
First you need to import the keys we use to sign packages.

$ wget -qO - https://raw.githubusercontent.com/linux-surface/linux-surface/master/pkg/keys/surface.asc \
    | gpg --dearmor | sudo dd of=/etc/apt/trusted.gpg.d/linux-surface.gpg
After this you can add the repository configuration and update APT.

$ echo "deb [arch=amd64] https://pkg.surfacelinux.com/debian release main" \
	| sudo tee /etc/apt/sources.list.d/linux-surface.list

$ sudo apt update
Now you can install the linux-surface kernel and its dependencies. You should also enable the iptsd service for touchscreen support.

$ sudo apt install linux-image-surface linux-headers-surface iptsd libwacom-surface

After that you can install the secureboot key. This will import the key that the linux-surface kernel is signed with into your bootloader, so that the kernel is bootable without disabling secureboot. This package will print instructions to the terminal, so please install it on its own, not as part of a bigger batch of packages.

If your Debian derivate does not support secure boot, please skip this step.
$ sudo apt install linux-surface-secureboot-mok

The linux-surface kernel will be installed alongside the default kernel provided by the distribution. This way you have a backup kernel you can use if something goes wrong. The bootloader will pick up the kernel by default, but you should update its configuration to make sure it was recognized.

$ sudo update-grub
Finally, reboot your system and you should boot into the linux-surface kernel. 

This should ask for the secureboot key password for the key to be installed. The password is "surface"

Please make sure you are actually using the right kernel by checking if the output of uname -a contains the string surface. If it doesn't contain that string, you are still using the default kernel and need to configure your bootloader.

===== Missing i915 firmware =====

To rectify initramfs and boot errors like:
<code>
W: Possible missing firmware /lib/firmware/i915/tgl_huc_7.5.0.bin for module i915
</code>

Download the missing firmware from:
http://anduin.linuxfromscratch.org/sources/linux-firmware/i915/
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/
and regenerate initramfs and update grub:

<code>
wget http://anduin.linuxfromscratch.org/sources/linux-firmware/i915/tgl_huc_7.5.0.bin
sudo mv tgl_huc_7.5.0.bin /lib/firmware/i915/
sudo chmod 755 /lib/firmware/i915/tgl_huc_7.5.0.bin 
sudo update-initramfs -u
sudo update-grub

Surface Kernel Github issue solved by upgrading apt to 2.0.9 (for ubuntu focal based distros)
see wiki https://github.com/linux-surface/linux-surface/wiki/Known-Issues-and-FAQ/d65bd6ee9cfbbbf74e6da76ddc52aa231be1be50
<code>
sudo add-apt-repository ppa:gpxbv/apt-urlfix
sudo apt-get update
sudo apt install apt
</code>

===== Screen resolution =====
The surface pro 3 has a native resolution of 2160x1440 with 3:2 aspect ratio. Fonts are too small on this resolution. A better resolution without using font or monitor scaling is 1920x1280 but this isn't available in drop downs.
Custom resolutions can be added using xrandr:
<code>
xrandr --newmode "1920x1280_60.00"  206.25  1920 2056 2256 2592  1280 1283 1293 1327 -hsync +vsync
xrandr --addmode eDP-1 "1920x1280_60.00"
</code>
Note that this is not permanent and after a reboot, the modelines do not exist any longer.

Add to rc.local / .profile or whatever best applies to your system.

This can be applied in lightdm:
<code - /etc/lightdm/lightdm.conf.d/70-linuxmint.conf>
[SeatDefaults]
user-session=cinnamon
display-setup-script=/usr/local/bin/screenfix.sh
</code>

<code bash /usr/local/bin/screenfix.sh>
#!/bin/sh
/usr/bin/xrandr --newmode "1920x1280_60.00"  206.25  1920 2056 2256 2592  1280 1283 1293 1327 -hsync +vsync
/usr/bin/xrandr --addmode eDP-1 "1920x1280_60.00" ;\
/usr/bin/xrandr --output eDP-1 --primary --mode 1920x1280_60.00 --rotate normal
exit 0
</code>
<code>
chmod 755 /usr/local/bin/screenfix.sh
</code>

Surface 6 has a native resolution of 2736x1824 in 3:2 aspect ratio. Scaling by 200% is applied by default in mint. 100% scaling with 2/3rds the resolution works better:
<code>
xrandr --newmode "1824x1216_59.96" 186.01 1824 1944 2144 2464 1216 1217 1220 1259 -hsync +vsync
xrandr --addmode eDP-1 "1824x1216_59.96"
</code>
