Phosh is the default desktop environment. This page is about alternatives…
GNOME Shell is the default desktop environment from GNOME. It uses mutter and Wayland or X11.
To install it on an existing Mobian installation, perform the following:
sudo apt update sudo apt install gdm3 sudo systemctl disable phosh && sudo systemctl enable gdm3
The GNOME onscreen keyboard can be summoned by swiping up from the bottom of the screen.
With GDM/GNOME Shell, there is no limitation on your user password, unlike with Phosh.
To switch between Phosh and GNOME Shell, all you have to do is enable/disable the conflicting services by running the following:
To enable GNOME Shell: sudo systemctl disable phosh && sudo systemctl enable gdm3 && sudo reboot To enable Phosh: sudo systemctl disable gdm3 && sudo systemctl enable phosh && sudo reboot
GNOME Shell is better with some tweaks to the top bar, which can be performed by doing the following:
gsettings set org.gnome.desktop.interface scaling-factor 1 (then log out and back in) sudo apt update sudo apt install gnome-tweaks wget https://extensions.gnome.org/extension-data/icon-hiderkalnitsky.org.v24.shell-extension.zip #(Icon Hider) wget https://extensions.gnome.org/extension-data/TaskBarc0ldplasma.v5.shell-extension.zip #(Taskbar 2020) wget https://extensions.gnome.org/extension-data/improvedoskluebke.io.v4.shell-extension.zip #(Improved Onscreen Keyboard) gnome-extensions install --force TaskBarc0ldplasma.v5.shell-extension.zip gnome-extensions install --force icon-hiderkalnitsky.org.v24.shell-extension.zip gnome-extensions install --force improvedoskluebke.io.v4.shell-extension.zip
Then log out and back in, and run the Tweaks app (if you cannot see the tabs, i.e. left side menu, in the gnome-tweaks app then you could try to switch to landscape mode). Under Fonts, change the scaling factor to 1.5, and then under Extensions enable both of the extensions, and tap their gear icons to change their settings. For Icon Hider, hide dwellClick, a11y, and keyboard. For Taskbar 2020, tap Panels on the left, then change Top Panel/Panel Size to 48, and Panel Content Size to -10. For Improved Onscreen Keyboard, change Portrait height to 20, Landscape height to 33, and make sure the checkbox for Resize Desktop is checked. You may need to log out and back in for all changes to apply.
You can also show the battery percentage at the right end of the top bar by running Tweaks, tapping Top Bar on the left panel, and enabling Battery Percentage.
Pinetab landscape mode
Put your gnome-shell to landscape mode or put the following file to '~/.config/monitors.xml'. This file example is Pinetab only.
<monitors version="2"> <configuration> <logicalmonitor> <x>0</x> <y>0</y> <scale>1</scale> <primary>yes</primary> <transform> <rotation>right</rotation> <flipped>no</flipped> </transform> <monitor> <monitorspec> <connector>DSI-1</connector> <vendor>unknown</vendor> <product>unknown</product> <serial>unknown</serial> </monitorspec> <mode> <width>800</width> <height>1280</height> <rate>58.286083221435547</rate> </mode> </monitor> </logicalmonitor> </configuration> </monitors>
If you want to have the gdm3 login in landscape too, do as root:
cp ~/.config/monitors.xml /var/lib/gdm3/.config/monitors.xml reboot
Lomiri is the desktop environment from Ubuntu Touch. It was originally Canonical's Unity desktop, but has been forked and maintained by UBports.
Jonah Brüchert is actively maintaing a Debian repository for Plasma Mobile packages. We can install it and switch to it with the following:
#. Get and install the repository keyring wget https://jbb.ghsq.ga/debpm/pool/main/d/debian-pm-repository/debian-pm-archive-keyring_20210819_all.deb sudo dpkg -i debian-pm-archive-keyring_20210819_all.deb #. Add the following to `/etc/apt/sources.list.d/debian-pm.list` file: deb https://jbb.ghsq.ga/debpm testing main #. Update the package database: sudo apt update #. Install the base packages: sudo apt install plasma-phone-components plasma-phone-settings plasma-settings plasma-phonebook plasma-angelfish plasma-nm simplelogin plasma-dialer spacebar #. Modify the simple login service to use the ``mobian`` user instead of ``phablet`` by editing the ``/lib/systemd/system/simplelogin.service`` file. #. Prevent `phosh.service` from auto-starting at future boots and enable simplelogin at its place:: sudo systemctl disable phosh && sudo systemctl enable simplelogin #. Reboot.
This procedure is not removing Phosh from the system, then it remains possible to start Phosh or Plasma by starting/stopping phosh.service or simplelogin.service. Starting/stopping services will not affect the desktop environment being launched at future boots, unless you also enable the service of the DE you want to start and disable the other.

LXDE is a lightweight X desktop. It is very fast on the Pinetab and usefull together with the keyboard / touchpad for the Pinetab. Here a picture with some tweaks (change font size at preferences, change panel hight and icon size).
The mousepointer is working out of the box in landscape mode, the touchpad does not rotate with the screen and need some tweaks. It is possible to install 'xinput' to use a command to rotate the touchscreen to the right position (270 degrees).
sudo apt install xinput # to install (only 1st time) xinput list # to verify the device name # the next does the rotate to 270 degrees and the touchscreen is usable xinput set-prop "pointer:Goodix Capacitive TouchScreen" --type=float "Coordinate Transformation Matrix" 0 1 0 -1 0 1 0 0 1
If everything is good this transform matrix can be used in a xorg .conf file to make it persistent.
sudo cp /usr/share/X11/xorg.conf.d/40-libinput.conf /etc/X11/xorg.conf.d/40-libinput.conf
Edit the touchscreen part in /etc/X11/xorg.conf.d/40-libinput.conf to let it look like this (or your transform matrix).
Section "InputClass" Identifier "libinput touchscreen catchall" MatchIsTouchscreen "on" MatchDevicePath "/dev/input/event*" Driver "libinput" Option "TransformationMatrix" "0 1 0 -1 0 1 0 0 1" EndSection
Using LXDE together with 'lightdm' a reboot to Phosh is possible for using the Pinetab without keyboard.
Maybe 'onboard' on LXDE is an option for a keyboardless Pinetab.
