Improvements from xfce4-phone source:
- Add screenshot to README.md
- Enable screen locking
- Disable Desktop icons "Home", "File System", "Trash"
- Enable single-click on Desktop
- Enable single-click in Thunar
- Change clock format
- Set postmarketos wallpaper
Additional changes in postmarketos-ui-xfce4:
- Installing greybird-themes (which is already set as default theme in
/etc/xdg/xfce4/xfconf/xfce-perchannel-xml/xsettings.xml).
- Changing /etc/skel/.config/autostart/onboard-autostart.desktop to
slightly speed up keysboard startup (overriding startup-delay of
/etc/xdg/autostart/onboard-autostart.desktop).
- Enabling scrollbars by /etc/profile.d/enable-scrollbars.sh, this is
helpful where touch-scrolling doesn't work like e.g. in whiskermenu.
(And re-ordered network-manager-applet in APKBUILD _pmb_recommends
section.)
Also removing xfce4 subpackages of device-qemu-amd64,
device-qemu-aarch64 and device-nokia-n900. The device specific monitor
to set the wallpaper will now be automatically derived from "monitor0"
in file xfce4-desktop.xml.
Additionally taking maintainership as discussed in merge request
(!2506).
