A guide for the [Surface Pro 8](https://github.com/linux-surface/linux-surface/wiki/Surface-Pro-8). Based on https://github.com/linux-surface/linux-surface/wiki.
|
|
|
|
This guide is for [ArchLinux](https://archlinux.org/) and improves the instructions to be more structured and suited for the SP8.
|
|
|
|
## Prerequisites
|
|
* USB adapter cable for USB A to USB C
|
|
* USB Drive, see [[KB/Linux/Desktop/Archinstall]] for getting an ISO onto USB
|
|
* External keyboard, because Type Cover will not work without custom kernel
|
|
|
|
## Prepare
|
|
* If Windows is still on disk, boot into it and update everything, so Surface firmware gets updated
|
|
* Head into BIOS to _change boot order_ and disable _Secure Boot_
|
|
* Shut down device
|
|
* Press and hold _Volume up_ and in parallel hit power button once until boot logo appears
|
|
* Keep _Volume up_ pressed
|
|
* Disable Secure Boot entirely
|
|
* Change boot order by drag'n'drop USB Drive to first position, maybe uncheck all other options
|
|
|
|
## Install
|
|
Boot from USB drive and edit ISO live boot options to copy USB drive contents to RAM, because you need to plug in an external keyboard for installation
|
|
|
|
* Press _e_ during selection of Arch ISO
|
|
* Add `copytoram=y` as option
|
|
* Exit with CTRL+x
|
|
|
|
Proceed with install like you would usually do. [[KB/Linux/Desktop/Archinstall]] is an easy way with little configuration to get an install up and running.
|
|
|
|
This installation uses `systemd-boot` as bootloader. Your experience of the tutorial may vary if you pick another one.
|
|
|
|
In generel, you should pick wayland. It has much better touch, gesture and pen support.
|
|
|
|
## Post install
|
|
|
|
After you've successfully booted into your installation, some additional steps need to be performed to get your Type Cover and touchpad etc. working.
|
|
|
|
Disclaimer: Don't mix the `iptsd` of the official repository with the `iptsd` mentioned here, they're different and may soon get merged.
|
|
|
|
### pacman repository
|
|
|
|
Let's add the the official _pacman_ repository of _linux-surface_
|
|
|
|
```shell
|
|
curl -s https://raw.githubusercontent.com/linux-surface/linux-surface/master/pkg/keys/surface.asc sudo pacman-key --add -
|
|
sudo pacman-key --finger 56C464BAAC421453
|
|
sudo pacman-key --lsign-key 56C464BAAC421453
|
|
```
|
|
|
|
Edit `/etc/pacman.conf`:
|
|
|
|
```shell
|
|
[linux-surface]
|
|
Server = https://pkg.surfacelinux.com/arch/
|
|
```
|
|
|
|
Refresh by invoking `sudo pacman -Syu`
|
|
|
|
### Install required packages
|
|
|
|
Install the following packages, some of them are also in the [AUR](https://aur.archlinux.org/).
|
|
|
|
```shell
|
|
# the actual kernel and their headers
|
|
linux-surface
|
|
linux-surface-headers
|
|
|
|
# SP 8 is an Intel device
|
|
intel-ucode
|
|
|
|
# needed for later compiling modules
|
|
dkms
|
|
meson
|
|
```
|
|
|
|
### Make touchpad work and allow Type Cover during early boot (luks)
|
|
|
|
Touchpad will _not_ work out of the box. The SP8 needs a different touchpad module and the _proper_ `iptsd`, not the one from the official linux-surface repository.
|
|
|
|
Ensure that `dkms` and `meson` are installed.
|
|
|
|
1. Clone `git clone https://github.com/quo/ithc-linux`
|
|
1. `cd ithc-linux`
|
|
2. Execute `sudo make dkms-install`
|
|
2. Clone `git clone https://github.com/quo/iptsd`
|
|
1. `cd iptsd`
|
|
2. Execute the following commands in order
|
|
|
|
```shell
|
|
meson build --wrap-mode=forcefallback --buildtype=debugoptimized -Dmarch=native
|
|
ninja -C build
|
|
sudo build/src/daemon/iptsd
|
|
sudo ninja -C build install
|
|
sudo systemctl daemon-reload
|
|
sudo systemctl enable iptsd.service
|
|
```
|
|
|
|
* For _ ithc_ to load properly, you need to edit kernel parameters in your `entries/....conf` file and add `intremap=nosid`. Add a `.conf` for the SP8 if not already present.
|
|
* You also need to edit the `MODULES` in your `/etc/mkinitcpio.conf` so that type cover will also work during early [encryption](https://github.com/linux-surface/linux-surface/wiki/Disk-Encryption) dialog
|
|
|
|
```shell
|
|
MODULES=(btrfs i915 surface_aggregator surface_aggregator_registry surface_aggregator_hub surface_hid_core 8250_dw surface_hid surface_kbd intel_lpss intel_lpss_pci pinctrl_tigerlake)
|
|
```
|
|
|
|
* Regenerate initramfs with `mkinitcpio -P`
|
|
* Reboot, you should no longer need your external keyboard
|
|
|
|
### pen
|
|
|
|
Install `libwacom-surface` from the [AUR](https://aur.archlinux.org/).
|
|
|
|
### screen rotation
|
|
|
|
Install `iio-sensor-proxy`.
|
|
|
|
### 120hz display
|
|
|
|
Follow instructions [here](https://github.com/linux-surface/linux-surface/wiki/Surface-Pro-8#enable-120hz-and-solve-screen-flickering) to extract the EDID. Ensure you're in X.org.
|
|
|
|
Afterwards, your `entries/....conf` systemd-boot entry could look like
|
|
|
|
```shell
|
|
title Arch Linux (linux-surface)
|
|
linux /vmlinuz-linux-surface
|
|
initrd /intel-ucode.img
|
|
initrd /initramfs-linux-surface.img
|
|
options ... intremap=nosid drm_kms_helper.edid_firmware=eDP-1:edid/edid.bin
|
|
```
|
|
|
|
In addition, your `/etc/mkinitcpio.conf` needs `FILES=(/usr/lib/firmware/edid/edid.bin)` and ensure you re-generate initramfs with `mkinitcpio -P`.
|
|
|
|
### Fix Type Cover suspend
|
|
|
|
If suspended via Type Cover, Touch might not work. Prevent this by editing `/etc/libinput/local-overrides.quirks` and add the following contents
|
|
|
|
```shell
|
|
[Microsoft Surface Cover]
|
|
MatchName=*Microsoft Surface *Cover*
|
|
MatchDMIModalias=dmi:*svnMicrosoftCorporation:*
|
|
AttrKeyboardIntegration=internal
|
|
ModelTabletModeNoSuspend=1
|
|
```
|
|
|
|
Reboot.
|
|
|
|
## Recommended software
|
|
|
|
[[KB/Linux/GNOME]] has wonderful support for touch devices. You should probably use it.
|
|
|
|
Useful GNOME extensions
|
|
* improved gestures `gestureImprovements@gestures` (https://extensions.gnome.org/extension/4245/gesture-improvements/)
|
|
* improved on screen keyboard `improved-osk` (https://extensions.gnome.org/extension/4413/improved-osk/)
|
|
