Installation
lk2nd is a secondary bootloader that provides a standard fastboot interface, which can be used to boot postmarketOS without Android boot flashed or pmbootstrap flasher flash_kernel.
- Download lk2nd-msm8916.img from Releases page on Github.
- Boot your phone to bootloader (Odin/Download) mode by holding Volume Down and Home while powering up.
- Follow lk2nd instructions to install lk2nd. Basically flash it to the boot partition (
heimdall flash --BOOT lk2nd-msm8916.img) - Follow Qualcomm_Snapdragon_410/412_(MSM8916)#Installation to install postmarketOS.
|
Note: Enter lk2nd fastboot mode by pressing only Volume Down + Power (without Home). Pressing Home additionally will bring you to the Samsung Download mode. |
Touch keys
For configuration of the touch keys, see Tm2-touchkey.
Display brightness
The brightness of the display can't be adjusted, this is not available yet.
Flash LED
Currently WIP. It can be controlled with SG Micro SGM3140 charge pump LED driver[1].
Suspend
Suspend is not yet fully implemented. It's recommended to disable suspend. See Qualcomm_Snapdragon_410/412_(MSM8916)#Suspend.
Mirrored screen on Plasma Mobile and GNOME mobile
On samsung-serranove the display natively shows everything in flipped/mirrored way. To compensate this, the kernel cmdline in /etc/deviceinfo contains video=540x960,reflect_x. In Plasma Mobile the screen handling is done by KScreen. As KScreen didn't support flipping/reflecting in Plasma 5, everything was shown mirrored. Since switching to Plasma 6, screen flipping is technically possible but isn't applied automatically. The issue is tracked in pmaports#1340. To solve the problem it's being worked on the panel kernel driver of samsung-serranove (Jakko).
As it turned out, also GNOME mobile is affected by this. While Phosh and GNOME use "mutter" as a Wayland compositor, GNOME mobile uses "mutter-mobile", which is in an experimental state and currently not capable to flip the screen.
Hardware Acceleration in Firefox
As of 04.01.2024 it was observed on phosh that firefox-esr has a broken UI on launch, this has been linked to the hardware acceleration currently tracked on #2332!pmaports and including a hotfix and on https://gitlab.freedesktop.org/mesa/mesa/-/issues/10374.
Official Support Checklist
1. Fix pmaports#1340 (Breaks gnome, gnome-mobile and plasma-mobile usability)
2. Fix pmaports#2332 (To be decided, if it turns out to be a mesa bug then it would have to be fixed otherwise minor issue)
Other components cannot be fixed due to lack of firmware source code and signing keys from Samsung including the limitation to use armv7 instead of aarch64 architecture
