i3 On Raspberry Pi Desktop OS On Mac

all you need to do after installing i3 is no need to mess around in /etc/xdg/LXDE or whatever.

vim ~/.dmrc

[Desktop]
# Session=lightdm-xsession
Session=i3

Also for getting renoise setup on this kingston a400 250gb ssd with raspberry pi desktop with persistence you need to add :amd64 to the end of the packages it says it can’t find on this imac.

GETTING RENOISE TO NOT STUTTER

sudo apt install cpufrequtils
sudo cpufreq-set -r -g performance
sudo vim /etc/init.d/cpufrequtils

## change GOVERNOR="ondemand" to
GOVERNOR="performance"

sudo vim /etc/security/limits.conf

#at the end of the file add username (where pi is)
# make sure you change to your username if its not pi!
pi - rtprio 99
pi - nice -10

Switching Between Multiple DEs

2 ways:

#1 - sudo apt install tasksel

#2 - run this command:

sudo update-alternatives --config x-session-manager

Getting Rofi Working in LXDE with CMD+D

sudo apt install xbindkeys and vim ~/.xbindkeysrc

# Launch Rofi drun with Mod+d
"rofi -show drun"
    mod4 + d

Renoise Is Installed But Won’t Run

Problem is this imac is amd64 and its looking packages that are installed but on the wrong architecture. If you are trying to install all required 64-bit dependencies for a particular program (like Renoise) and you don’t want to manually install each package, you can use the following method:

• First, ensure all the required dependencies are identified:

ldd $(which renoise)
# then install missing packages
sudo apt install libasound2:amd64 libxext6:amd64 libstdc++6:amd64 pulseaudio:amd64

So You Don’t Have to Keep Adding :amd64 to each package

sudo dpkg --add-architecture amd64
sudo apt update
# force it to look for amd64
sudo vim /etc/apt/preferences.d/99amd64
# add these lines
Package: *
Pin: release a=stable
Pin-Priority: 700

Package: *
Pin: architecture amd64
Pin-Priority: 800
