Plasma Mobile configuration - Surehand53 - 07-05-2023

Plasma Mobile configuration

The examples in this text are for the factory danctnix distro of Archlinux for the Pinetab 2.

In the guide to install plasma mobile on the Pinetab 2 here we have the issue that the package plasma-mobile-settings cannot be installed doe to some file conflicts.

Plasma Mobile also works ok without that package, but what is it that is configured there and what is useful for the Pinetab 2?

The plasma-mobile-settings package

There are different variations of this package.

Here is the content of the folder that failed to install previously.
Code:
Filename                          Description
90-plasma-flashlight.rules        pkg: plasma: plasma-mobile-settings: various improvements
91_plasma-mobile.gschema.override pkg: plasma: plasma-mobile-settings: new pkgbuild
PKGBUILD                          pkg: plasma: plasma-mobile-settings: remove window decorations
applications-blacklistrc          pkg: plasma: plasma-mobile-settings: blacklist vlc from home screen
kde-tweaks.sh                     pkg: plasma: plasma-mobile-settings: various improvements
kdeglobals                        pkg: plasma: plasma-mobile-settings: update settings
kdewallet.kwl                     pkg: plasma: plasma-mobile-settings: add blank kwallet
kdewallet.salt                    pkg: plasma: plasma-mobile-settings: add blank kwallet
kscreenlockerrc                   pkg: plasma: plasma-mobile-settings: start session locked
kwinrc                            pkg: plasma: plasma-mobile-settings: remove window decorations
plasma-mobile-settings.install    pkg: plasma: plasma-mobile-settings: disable ofonoctl
plasmamobile.json                 pkg: plasma: plasma-mobile-settings: new pkgbuild
powerdevil.hook                   pkg: plasma: plasma-mobile-settings: alarm wakeup and flashlight
settings.ini                      pkg: plasma: plasma-mobile-settings: new pkgbuild
startkderc                        pkg: plasma: plasma-mobile-settings: switch to mm & enable sysdboot
We will check what's inside and what is worth to install manually.

90-plasma-flashlight.rules

Folder: /usr/lib/udev/rules.d/
The Pinetab2 doesn't have a flashlight. I skip this file.

Code:
SUBSYSTEM=="leds", ACTION=="add", KERNEL=="white:flash", \
  RUN+="/bin/chmod 666 /sys/class/leds/%k/brightness"

91_plasma-mobile.gschema.override

Folder: /usr/share/glib-2.0/schemas

I guess this impacts GDK.

Code:
[org.maliit.keyboard.maliit]
device='plasmamobile'
theme='Breeze'
This is not the place where the plasmamobile device for Plasma Mobile is set.

PKGBUILD

This is the script that installs the package. Very useful to see how and in which folder which file gets installed.

Example:

Code:
...
package() {
    xdg=$pkgdir/etc/xdg
    install -Dm644 applications-blacklistrc $xdg/applications-blacklistrc
    install -Dm644 kdeglobals $xdg/kdeglobals
    install -Dm644 kwinrc $xdg/kwinrc
    install -Dm644 kscreenlockerrc $xdg/kscreenlockerrc
    install -Dm644 startkderc $xdg/startkderc
    install -Dm644 "${srcdir}/91_plasma-mobile.gschema.override" -t "${pkgdir}/usr/share/glib-2.0/schemas"
    install -Dm644 "${srcdir}/plasmamobile.json" -t "${pkgdir}/usr/share/maliit/keyboard2/devices/"
    install -Dm644 "${srcdir}/settings.ini" -t "${pkgdir}/etc/skel/.config/gtk-3.0/"
...

application-blacklist

Folder: /etc/xdg

Lists applications that are not shown in the Application view. e.g.:

Code:
blacklist=cuttlefish,org.kde.plasma.themeexplorer,org.k ...

kde-tweaks.sh

Folder: /etc/profile.d/

Code:
# This makes Kirigami apps go smoother such as Angelfish.
export KIRIGAMI_LOWPOWER_HARDWARE=1

# Most pure GTK3/Qt apps use wayland by default, but some,
# like Firefox, need the backend to be explicitely selected.
export MOZ_ENABLE_WAYLAND=1

kdeglobals

Folder: /etc/xdg/

Code:
[General]
BrowserApplication[$e]=!angelfish

[KDE]
LookAndFeelPackage=org.kde.plasma.phone

kdewallet.kwl and kdewallet.alt

No idea what these package do. For now I skip these. Kwallet seems to work anyway.

kscreenlockerrc

Folder: /etc/xdg/  I have not installed this yet.

Code:
[Daemon]
LockOnStart=true

kwinrc

Folder: /etc/xdg/

Here is a mix of the KDE Plasma Mobile and Danctnix settings:

Code:
[Plugins]
# Blur is far too slow for many mobile devices, don't have it enabled by default
blurEnabled=false

[Wayland]
InputMethod[$e]=/usr/share/applications/com.github.maliit.keyboard.desktop
VirtualKeyboardEnabled=true

# This is here for legacy purposes since look-and-feel packages don't have an upgrade path
# If the device came installed with Plasma 5.26 or newer, then this is not needed
# Edit: Commented out as not needed for the PineTab2 (starts with Plasma 5.27)
#[org.kde.kdecoration2]
#NoPlugin=true

plasma-mobile-settings.install

Not quite sure what this does. Activate the settings after the install ?

plasmamobile.json

In /usr/share/maliit/keyboard2/devices/

With this file you can change the look of the Maliit virtual keyboard that is used as standard in Plasma-mobile.

There can be several, quite similar files here. plasmamobile.json is the one that is used. I am not sure where it is configured to use plasmamobile.json.

These parameters set the height of the virtual keyboard for portrait and landscape mode. For me these values work:

Code:
  "keyboardHeightPortrait": 0.22,
  "keyboardHeightLandscape": 0.35,

powerdevil.hook

Folder: /usr/share/libalpm/hooks/

Code:
[Trigger]
Type = Path
Operation = Install
Operation = Upgrade
Target = usr/lib/org_kde_powerdevil

[Action]
Description = Enhance Powerdevil privileges for mobile usage ...
When = PostTransaction
NeedsTargets
Exec = /bin/sh -c 'setcap cap_wake_alarm+ep /usr/lib/org_kde_powerdevil'

settings.ini

Folder: ]/etc/skel/.config/gtk-3.0/

Some GTK settings

Code:
[Settings]
gtk-application-prefer-dark-theme=false
gtk-button-images=1
gtk-cursor-theme-name=breeze_cursors
gtk-fallback-icon-theme=Adwaita
gtk-font-name=Noto Sans Regular 10
gtk-icon-theme-name=breeze
gtk-menu-images=1
gtk-primary-button-warps-slider=0
gtk-theme-name=Breeze
gtk-toolbar-style=GTK_TOOLBAR_BOTH_HORIZ

startkderc

Folder: /etc/xdg/

Code:
[General]
systemdBoot=true


If you find more config files or setting, please let me know.
