This page contains information on problems I had and have with setting up Plasma Mobile on my Raspberry Pi3b+, solutions to them and steps to get it running yourself. Picture of my RasPad with Raspberry Pi 3b+ inside running Plasma Mobile Contents 1 Install instructions 2 Problems with solutions 3 Problems 4 Tips Install instructions Install Raspbian on the Raspberry Pi Update your firmware with sudo rpi-update Activate your GL driver in sudo raspi-config or by adding dtoverlay=vc4-kms-v3d to /boot/config.txt Open /etc/apt/sources.list and change deb http://raspbian.raspberrypi.org/raspbian/ stetch main contrib non-free rpi to deb http://raspbian.raspberrypi.org/raspbian/ buster main contrib non-free rpi; Add the official Debian repository by adding deb http://ftp.debian.org/debian/ buster main contrib non-free and getting its key sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 8B48AD6246925553 And the Plasma Mobile repository by adding deb https://debian-pm-tools.github.io/apt-repo buster main. Now upgrade your system by running sudo apt-get update and sudo apt-get upgrade. To an important step: You can now either change your user to "phablet" or set up ssh by adding an empty ssh.txt to /boot/. Install plasma-phone-components, plasma-phone-settings, plasma-settings, kwin-wayland, simplelogin and dbus-x11 by running sudo apt-get install plasma-phone-components plasma-phone-settings plasma-settings kwin-wayland simplelogin dbus-x11 Also install qtvirtualkeyboard if you want an on-screen keyboard. If you didn't change your user to "phablet" your screen will be frozen now. You can fix that by changing /lib/systemd/system/simplelogin.service; just change "phablet" to the user you want to run Plasma Mobile as; After a reboot your system should boot into Plasma Mobile. Problems with solutions Plasma Mobile does not launch without adding dtoverlay=vc4-kms-v3d to /boot/config.txt to activate the accelerated graphics driver. The Raspbian repo was unreachable over Wifi so I needed to use Ethernet. Simplelogin is installed with user "phablet" as running argument, is immediately run after installation and freezes the screen when run without a proper user; To counter this you can either create user "phablet" before installing or change the /lib/systemd/system/simplelogin.service to account for your current user. Problems Sometimes the screen freezes.

You may need to enable CMA or give it more memory. This happens regardless of how much memory your give the GPU and if you enable CMA. Angelfish never finishes loading webpages. Firefox ESR cannot play youtube videos as it is unable to install openh264. Tips As Plasma Mobile is running on an SD-Card; The speed of the SD-Card is pretty important for its performance. I used a Class 10 card which to me seems to be pretty much the minimum of what you would want to use. You can add more verbosity to your Plasma Mobile logging by creating /home/$USER/.config/QtProject/qtlogging.ini and adding [Rules] org.kde.kwindowsystem.info=true org.kde.kwindowsystem.warning=true org.kde.kwindowsystem.critical=true org.kde.kwindowsystem.debug=true kwin_core.info=true kwin_core.warning=true kwin_core.critical=true kwin_core.debug=true kwineffects.info=true kwineffects.warning=true kwineffects.critical=true kwineffects.debug=true libkwineffects.info=true libkwineffects.warning=true libkwineffects.critical=true libkwineffects.debug=true libkwinglutils.info=true libkwinglutils.warning=true libkwinglutils.critical=true libkwinglutils.debug=true libkwinxrenderutils.info=true libkwinxrenderutils.warning=true libkwinxrenderutils.critical=true libkwinxrenderutils.debug=true kwin_wayland_drm.info=true kwin_wayland_drm.warning=true kwin_wayland_drm.critical=true kwin_wayland_drm.debug=true kwin_wayland_framebuffer.info=true kwin_wayland_framebuffer.warning=true kwin_wayland_framebuffer.critical=true kwin_wayland_framebuffer.debug=true kwin_wayland_hwcomposer.debug=true kwin_wayland_backend.info=true kwin_wayland_backend.warning=true kwin_wayland_backend.critical=true kwin_wayland_backend.debug=true kwin_wayland_x11windowed.info=true kwin_wayland_x11windowed.warning=true kwin_wayland_x11windowed.critical=true kwin_wayland_x11windowed.debug=true kwin_platform_x11_standalone.info=true kwin_platform_x11_standalone.warning=true kwin_platform_x11_standalone.critical=true kwin_platform_x11_standalone.debug=true kwin_libinput.info=true kwin_libinput.warning=true kwin_libinput.critical=true kwin_libinput.debug=true kwin_tabbox.info=true kwin_tabbox.warning=true kwin_tabbox.critical=true kwin_tabbox.debug=true kwin_decorations.info=true kwin_decorations.warning=true kwin_decorations.critical=true kwin_decorations.debug=true kwin_scripting.info=true kwin_scripting.warning=true kwin_scripting.critical=true kwin_scripting.debug=true kwin_xkbcommon.info=true kwin_xkbcommon.warning=true kwin_xkbcommon.critical=true kwin_xkbcommon.debug=true kwin_qpa_plugin.info=true kwin_qpa_plugin.warning=true kwin_qpa_plugin.critical=true kwin_qpa_plugin.debug=true to it.
