Hardware

My version: 3 GB RAM, 32 GB eMMC + dock, Mobian edition — hardware revision is probably https://wiki.pine64.org/wiki/PinePhone_v1.2b

USB OTG works (tested with SparkFun GPS-RTK-SMA ZED-F9P).

eMMC state:

Common for Mobian and postmarketOS (but postmarketOS has no modules, they are probably compiled into the kernel).

Software

Mobian

Debian 11 Bullseye + Wayland + Phosh (Gnome).

/boot = ~500 MB, ext4. / = f2fs, auto-resize on first boot.

After installation, it took about 3.5 GB space in /. ~480 MB RAM used after boot.

Using swap on zram by default:

 $ sudo swapon --summary
Filename				Type		Size	Used	Priority
/dev/zram0                             	partition	1500816	0	100

Mobian Phosh

Mobian Phosh additional software

See also: User:Knuxfanwin8/Phosh Apps.

Applications I tried with Mobian Phosh:

App Short description Mobile Notes
clementine Audio player, Qt5 No It is possible to use in both portrait and landscape modes
foxtrotgps Mapping and GPS application, GTK No
Mobian Phosh pros and cons

Advantages/pros:

  • Hardware works fine: Wi-Fi, loud speaker, charger, …;
  • Redshift works;
  • Smooth interface in Firefox ESR, webext-ublock-origin-firefox, additional settings are in package firefox-esr-mobile-config, source https://gitlab.com/postmarketOS/mobile-config-firefox;
  • It is possibly to switch off/reboot system from menu;

Disadvantages/drawbacks/cons:

  • Camera clicks 4 times after OS boot up, when login page appears;
  • Only one system button, no "back" button;
  • No button to close applications;
  • Scaling is only 100% and 200%;
  • Virtual keyboard squeekboard is not comfortable;
  • Application Settings can forget about screen size and show only part of self;
  • Automatic brightness works too fast;
  • Automatic rotation works instantly without a delay — bad when sensor is between of two states + noise, need at least some Schmitt trigger;
  • No automatic night mode;
  • Alarm in gnome-clocks didn't give me a notification at morning (workaround: Wake Mobile, apt install wake-mobile);
  • Long start of applications from SD card;
  • Spend full battery for only one day;

postmarketOS

Alpine + Phosh / Plasma Mobile / Sxmo (and also Plasma Desktop, Gnome 3, Kodi, XFCE4, … ?).

Logs: By default postmarketOS uses the busybox logging daemon for the syslog and it's configured to log to memory only. The logread command is used to read the in-memory log.

BusyBox as default shell.

After install:

sudo apk add -i zsh vim
chsh -s /bin/zsh
sudo rc-update add sshd default
sudo apk add -i avahi
sudo rc-update add avahi-daemon default

Default /etc/apk/repositories:

http://mirror.postmarketos.org/postmarketos/v21.03
http://dl-2.alpinelinux.org/alpine/v3.13/main
http://dl-2.alpinelinux.org/alpine/v3.13/community

Plasma mobile

See also: Plasma Mobile.

tinydm-openrc, plasma-phone-components, postmarketos-ui-plasma-mobile (customizations).

/boot = ~250 MB, ext2. / = ~2.1 GB, ext4, auto-resize on first boot. /tmp not in tmpfs!

No swap by default.

Linux kernel:

Linux pine64-pinephone 5.11.0 #1-postmarketos-allwinner SMP Sat Mar 27 14:48:00 UTC 2021 aarch64 Linux

/proc/cmdline:

init=/init.sh rw console=tty0 console=ttyS0,115200 earlycon=uart,mmio32,0x01c28000 panic=10 consoleblank=0 loglevel=1 cma=256M PMOS_NO_OUTPUT_REDIRECT PMOS_FORCE_PARTITION_RESIZE pmos_boot=/dev/mmcblk0p1 pmos_root=/dev/mmcblk0p2

I installed VVAVE as audio player. But: VVAVE makes use of multiple web APIs of music knowledge to collect data.

Plasma mobile pros and cons

Advantages/pros:

  • Automatic night mode works;
  • Default virtual keyboard is more comfortable than in Phosh;
  • Interface logic is similar to Android and even better;
  • Automatic rotation has small delay, which is good, but anyway too fast;

Disadvantages/drawbacks/cons:

  1. Graphical interface as a whole works not as smooth as Phosh in Mobian;
  2. No automatic connection to Wi-Fi after restart;
  3. Lost Wi-Fi card after night;
  4. Alarm in Clock 0.3.0 didn't give me a notification at morning;
  5. Disabling the alarm requires entering PIN;
  6. No possibility to switch off/reboot system from menu, the only way is to hold the power button for about three seconds
  7. Unexpected reboots (crashes?) of graphical interface;
     $ grep 'KCrash: Application Name' ~/.cache/tinydm.log
    KCrash: Application Name = klauncher path = /usr/lib/libexec/kf5 pid = 3090
    KCrash: Application Name = polkit-kde-authentication-agent-1 path = /usr/lib/libexec pid = 3178
    KCrash: Application Name = kded5 path = /usr/bin pid = 3118
    KCrash: Application Name = DiscoverNotifier path = /usr/lib/libexec pid = 3184
    KCrash: Application Name = org_kde_powerdevil path = /usr/lib/libexec pid = 3171
    KCrash: Application Name = plasmashell path = /usr/bin pid = 3176
    

Sxmo

Simple X Mobile, is a collection of simple and suckless X programs and scripts.

The core of the Sxmo UI is based on the dwm window manager, the dmenu menu system, the lisgd gesture daemon and the svkbd keyboard.

+ feh (wallpaper), conky (desktop clock), clickclack (audio/vibration feedback on keypress).

Must read: https://git.sr.ht/~mil/sxmo-docs/tree/master/USERGUIDE.md — you have to learn all the gestures to use it.

/boot = ~250 MB, ext2. / = ext4, auto-resize on first boot.

After installation, it took about 1 GB space in /. ~120 MB RAM used after boot.

No swap by default.

Linux kernel:

Linux pine64-pinephone 5.11.0 #1-postmarketos-allwinner SMP Sat Mar 27 14:48:00 UTC 2021 aarch64 GNU/Linux

/proc/cmdline:

init=/init.sh rw console=tty0 console=ttyS0,115200 earlycon=uart,mmio32,0x01c28000 panic=10 consoleblank=0 loglevel=1 cma=256M PMOS_NO_OUTPUT_REDIRECT PMOS_FORCE_PARTITION_RESIZE pmos_boot=/dev/mmcblk0p1 pmos_root=/dev/mmcblk0p2

Important settings are in ~/.config/sxmo/xinit.

A lot of useful scripts are in /usr/bin/sxmo*.

Apps menu list don't need to restart after package installation.

Sxmo additional software

Applications I tried with Sxmo:

App Short description Mobile Notes
audacious Audio player No no controls in GUI, in WinAmp mode can't work without mouse — controls are too small
vlc Video/audio player No has app menu, can't start
thunar File manager Yes is in list of apps, but no app menu
Sxmo pros and cons

Advantages/pros:

  • Low resources usage for own needs (~1 GB flash space and ~120 MB RAM);
  • Wi-Fi works before login/unlock!
  • It is possibly to switch off/reboot system from menu;

Disadvantages/drawbacks/cons:

  • USB mouse not works by default,
