Bootloader original status

Installation

The following steps boots postmarketOS.

  • pmbootstrap flasher flash_rootfs
  • pmbootstrap flasher flash_kernel
  • pmbootstrap flasher boot

Plasma Mobile

Need to modify the file /usr/bin/startplasmamobile

Add --framebuffer --fb-device /dev/fb0 to arguments of startplasma-wayland

Like this: 

startplasma-wayland --framebuffer --fb-device /dev/fb0 --xwayland --lockscreen --inputmethod maliit-keyboard --exit-with-session=/usr/lib/libexec/startplasma-waylandsession

This ensures that the Plasma Mobile is rendered using a frame buffer.

Current boot status

Currently (Linux 4.9.117, edge, 01 Nov 2023) on Plasma Mobile (both using framebuffer and not), Gnome Mobile and Phosh phone boots up, successfully shows loading animation, resizes system partition on first boot, starts SSHd (so you can SSH into) but after that loading animation stops and desktop environment doesn't show up.

Xfce4 works out-of-the-box.

Here is an output of startplasma-wayland: 

qt.qpa.wayland: Creating a fake screen in order for Qt not to crash
The Wayland connection broke. Did the Wayland compositor die?
