This is a new page, currently under construction!


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.


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 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. Crop from syslog:
kernel: [ 4903.278101] vc4-drm soc:gpu: failed to allocate buffer with size 16777216
kernel: [ 4903.278609] vc4-drm soc:gpu: failed to allocate buffer with size 16777216

kernel: [ 4903.279699] vc4_v3d 3fc00000.v3d: Failed to allocate memory for tile binning: -12. 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

  • You can add more verbosity to your Plasma Mobile logging by creating /home/USER/. config/QtProject/qtlogging.ini and adding
