This is the UI from [[Maemo]] Fremantle, which is a Debian-based distribution that originally ran on the Nokia N900. postmarketOS had an incomplete and not well maintained Hildon port based on the Maemo Leste sources, until April of 2020. It was removed as several features were missing, broken, and we could not upgrade it without investing much time to resolve packaging conflicts.
We do not have a <code>postmarketos-ui-hildon</code> yet (but that should be easy to make, look at <code>postmarketos-ui-weston</code> for reference if you're interested, dear reader).


=== Installation instructions ===
The Maemo Leste project runs Hildon on top of a recent Devuan (Debian fork) with OpenRC (same init system as Alpine), and all the devices they are targeting run the mainline kernel (Droid 4, N900, N9, ...). So for anybody who wants to run Hildon, check out '''[https://maemo-leste.github.io/ Maemo Leste].'''


Add following packages as extra in pmbootstrap init:
If somebody is willing to invest a lot of time for a new postmarketOS port of Hildon/Maemo Leste, let us know in the issues!
<pre>mesa,mesa-dri-swrast,hildon-desktop,hildon-theme-alpha</pre>


Notice that due to swrast being used (probably) this is way too slow to be usable on N900. Even typing in xfce4-terminal results in one second lag.

<pre class="shell">sudo ln -s /usr/share/themes/alpha /usr/share/themes/default</pre>
For default wallpapers:
 
<pre>mkdir ~/.backgrounds
cp /usr/share/themes/alpha/backgrounds/wallpaper1.png ~/.backgrounds/background-1.png
cp /usr/share/themes/alpha/backgrounds/wallpaper2.png ~/.backgrounds/background-2.png
cp /usr/share/themes/alpha/backgrounds/wallpaper3.png ~/.backgrounds/background-3.png
cp /usr/share/themes/alpha/backgrounds/wallpaper4.png ~/.backgrounds/background-4.png</pre>
 
You can then verify correct operation by ssh-ing in, as root:
 
<pre>
sudo mv /etc/profile.d/start_weston.sh /etc
sudo killall weston
sudo rc-update add dbus default
sudo setup-xorg-base
Xorg &
DISPLAY=:0
export DISPLAY
hildon-desktop
</pre>
 
=== Running ===
 
To run hildon-desktop, create a <code>~/.xinitrc</code> with the following contents:
 
<pre>
if which dbus-launch >/dev/null && test -z "$DBUS_SESSION_BUS_ADDRESS"; then
    eval `dbus-launch --sh-syntax --exit-with-session`
fi
export LC_MESSAGES=en_GB.UTF-8
exec hildon-desktop
</pre>
 
You will also have to install <code>dbus-x11</code> in order to get <code>dbus-launch</code>. Depending on the device you have, you may also have to install <code>mesa-dri-swrast</code>.
 
hildon-desktop can then be started by running <code>startx</code>.
 
=== Performance problems ===
Hildon renders everything on the GPU, which is terribly slow when we have to resort to software rendering. At least on the N900 it is not usable at all. The GTK+3 version won't improve this, as it also uses Clutter for rendering. We could try to use [https://github.com/lunixbochs/tinygles tinygles] instead of mesa, which does software rendering only and is optimized for performance. It is a bit dated though, so no idea if it will actually be faster. [https://github.com/lunixbochs/tinygles/issues/9 Asked for opinion from upstream.]

Hildon on the Nexus 7 2013 with postmarketOS

This is the UI from Maemo Fremantle, which is a Debian-based distribution that originally ran on the Nokia N900. postmarketOS had an incomplete and not well maintained Hildon port based on the Maemo Leste sources, until April of 2020. It was removed as several features were missing, broken, and we could not upgrade it without investing much time to resolve packaging conflicts.

The Maemo Leste project runs Hildon on top of a recent Devuan (Debian fork) with OpenRC (same init system as Alpine), and all the devices they are targeting run the mainline kernel (Droid 4, N900, N9, ...). So for anybody who wants to run Hildon, check out Maemo Leste.

If somebody is willing to invest a lot of time for a new postmarketOS port of Hildon/Maemo Leste, let us know in the issues!
