Version 1/2/3 does NOT support RaspberryPi 5

You can build it yourself for FREE by following the instructions below.

TitusPi Version 3 (2023 Edition)

Terminal Desktop KDE Profile

This version is designed for max stability and ease of use. The build instructions are simplistic and only require minor tweaks for the raspberrypi.

Build instructions

disable_splash=1
disable_overscan=1
hdmi_group=1
hdmi_mode=4
hdmi_drive=2
hdmi_ignore_cec_init=1
arm_freq=2048
v3d_freq=750
over_voltage=6
dtparam=i2c_arm=on
dtparam=audio=on
enable_uart=1
[pi4]
dtoverlay=vc4-fkms-v3d
[all]
hdmi_enable_4kp60=1

Seems my RPi4 version is more sensitive to what chargers I can use, therefore limiting overclocking options.

cat /proc/cpuinfo | grep Revision

Revision: c03111

Overclocking

Reference: <www.raspberrypi.org/documentation/configuration/config-txt/overclocking.md>

These are the speeds I achieved with arm_freq=2048. arm_freq=2047 reports a lower scaling_max_freq which can be noticed in games like God of War: Chains of Olympus (one of the games I used as benchmark). v3d_freq=750 is the max GPU overclock, over_voltage=6 required to provide extra juice (over_voltage=5 worked for me with arm_freq=2000).

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

2194967

echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

vcgencmd measure_clock arm frequency(48)=2048519552

As for hdmi_enable_4kp60=1 I also use it for overclocking reasons, as the only way to increase the GPU core_freq from 500 to 550, enable_tvout underclocks to 360: "Specific to Pi 4B: The core_freq of the Raspberry Pi 4 can change from the default if either hdmi_enable_4kp60 or enable_tvout are used, due to relationship between internal clocks and the particular requirements of the requested display modes."

HDMI options and resolution

Reference: <www.raspberrypi.org/documentation/configuration/config-txt/video.md>

hdmi_group=1, hdmi_mode=4, hdmi_drive=2 : these options set the RPi at 16:9 720p using the standard CEA TV timings and sending audio through HDMI.

hdmi_ignore_cec_init=1 "prevents a CEC-enabled TV from coming out of standby and channel-switching when you are rebooting your Raspberry Pi." Channel switching on reboots was quite annoying indeed :)

No gpu_mem parameters??

Reference: <www.raspberrypi.org/documentation/configuration/config-txt/memory.md>

That's right! :) "On the Raspberry Pi 4 the 3D component of the GPU has its own memory management unit (MMU), and does not use memory from the gpu_mem allocation. Instead memory is allocated dynamically within Linux. This may allow a smaller value to be specified for gpu_mem on the Pi 4, compared to previous models." Note: Still recommended for Pi 3's if using for emulation!

The performance of N64 Conker's Bad Fur Day increased noticeably after removing all gpu_mem parameters.

TitusPi Verison 1/2 - A Raspberry Pi Desktop Distribution that doesn't suck

Original work by PapyElGringo, he is now developing material-shell for GNOME

An almost desktop environment made with AwesomeWM following the Material Design guidelines with a performant opiniated mouse/keyboard workflow to increase daily productivity and comfort.

Before you Start

I have created two different systems for TitusPi. Below you will find two paths... Arch Install or Raspbian OS Install. Choose one and DO NOT run commands for both.

These instructions are not complete as there are components missing to build the base OS install. (Xorg and other dependencies) If you have ever built arch before you will be familiar with the build process. It is almost identical - https://wiki.archlinux.org/index.php/installation_guide . I will update the project with each build, but it will take a long time before the instructions will be complete due to the complexity of building this.

Any extra scripts and modifications I made is in the extras folder in this project. The script I use for changing to tty1 to run emulationstation or the emulationstation.desktop file are extras I have added.

Other modifications to the systems:

Download

Arch Base Installation

Root Pacman Setup

pacman -S xorg xorg-drivers mesa lightdm lightdm-gtk-greeter base-devel vim nano sudo clang cmake git gcc glibc networkmanager

Yay Install with User (DO NOT USE ROOT)

git clone "https://aur.archlinux.org/yay.git"
cd yay
makepkg -si

Service Setup on Boot

sudo systemctl enable NetworkManager
sudo systemctl enable lightdm
sudo systemctl enable systemd-timesyncd

Raspberry Pi OS Base Installation

Work In Progress - Look at the Arch install and install those packages (Note: some are a bit different because of the package manager differences)

Material Awesome Setup

Raspbian-Based

sudo apt install awesome fonts-roboto rofi compton i3lock xclip qt5-style-plugins materia-gtk-theme lxappearance xbacklight flameshot nautilus xfce4-power-manager pnmixer network-manager-gnome policykit-1-gnome terminator chromium gedit nautilus -y
wget -qO- https://git.io/papirus-icon-theme-install | sh

Note: picom replaced with compton in pi because of ARM Architecture

Arch-Based

yay -S awesome rofi picom i3lock-fancy xclip ttf-roboto polkit-gnome materia-gtk-theme lxappearance flameshot pnmixer network-manager-applet xfce4-power-manager terminator chromium gedit nautilus -y
wget -qO- https://git.io/papirus-icon-theme-install | sh

Program list

Clone the configuration

git clone https://github.com/ChrisTitusTech/TitusPi.git ~/.config/awesome

Set the themes

Start lxappearance to active the icon theme and GTK theme Note: for cursor theme, edit ~/.icons/default/index.theme and ~/.config/gtk3-0/settings.ini, for the change to also show up in applications run as root, copy the 2 files over to their respective place in /root.

Same theme for Qt/KDE applications and GTK applications, and fix missing indicators

First install qt5-style-plugins (debian) | qt5-styleplugins (arch) and add this to the bottom of your /etc/environment

XDG_CURRENT_DESKTOP=Unity
QT_QPA_PLATFORMTHEME=gtk2

The first variable fixes most indicators (especially electron based ones!), the second tells Qt and KDE applications to use your gtk2 theme set through lxappearance.

Changing the Matrial Awesome Theme

The documentation live within the source code.

The project is split in functional directories and in each of them there is a readme where you can get additional information about the them.
