This is the way I set up my ubuntu 18.04 Install last time I did it. In this order

Do this before installing ubuntu. Or at least before anything else

• disable secure boot in BIOS
• also in bios it may be necessary to disable hybrid graphics. I currently have hybrid graphics disabled too, but I think with nvidia-prime you can leave this on and actually switch between the nvidia gpu and the integrated intel gpu(much better battery life)

Do this befor you start trying to figure anything else out becasue a lot of things wont be set up right yet

sudo apt update

sudo apt upgrade

sudo reboot now

• you can do this from command line by adding a repo and then apt installing the drivers from there.

• But it is a little more fool-proof to just go to Software & Updates then click additional-drivers and select the newest nvidia one then wait for it to finish then reboot again.

• you can verify it is working by going to settings->details and the nvidia GPU should be listed instead of the integrated one. also running nvidia-smi will show gpu usage (this will only work after it is set up)

• nvidia-settings opens a display menu to customize settings

using NVIDIA's installation guide walks you through this pretty well. But I will include some helpful tips that I used

• this was helpful when trying to install cuda stuff (it broke apt and this recovered it)

sudo apt-get -o Dpkg::Options::="--force-overwrite" install --fix-broken

• also if you get to making the sample cuda stuff and you get an error that says something about "missing nvscibuf.h" there is actually a missing file or something in cuda 10.2 so on the nvidia forum they said they are researching, but for now to just use make -k (to keep going after the error and build the other stuff)

wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb

sudo dpkg -i google-chrome-stable_current_amd64.deb

sudo apt install htop vim vim-gtk curl git ssh git-gui usb-creator-gtk baobab avahi-daemon avahi-utils

• the usb-creator-gtk (called startup disk creator) is good for making bootable drives
• baobab (called disk usage analyzer)
• the avahi stuff is nice to find hosntames and stuff on a network

• this will create a public ssh key at ~/.ssh/id_rsa.pub

ssh-keygen -t rsa -b 4096 -C "[email protected]"

• add the ssh keys at gitlab/github click on profile then settings then ssh-keys then add ssh key and copy it into there

This is good to do next because it will install a lot of other dependencies that you will need

• best to do it with the update_dependencies script because that handles ros and all of the other dependencies that we need here. it is in anansi_dev_tools/flight_computer_setup just clone this repo.
• before you run the script, make sure that the folder that you have installed it into is in the possible_code_dirs arguement on line 14
  • for exmaple: I install this is a directory called workspaces in my home directory so I add this on to the end "${USER_HOME}/workspaces"
• then run the script ./update_dependencies.sh

This will install ROS and python and pip install a lot of python packages as well

I like to use a few gnome extensions.

NOTE: These will only work on gnome

sudo apt install gnome-tweaks chrome-gnome-shell gnome-shell-extensions

• then add the gnome extension to chrome here

• if you want to use GnomeStatsPro or system-monitor extensions you need to run this too

sudo apt install gir1.2-gtop-2.0 gir1.2-nm-1.0 gir1.2-clutter-1.0 gnome-system-monitor

• I Installed topicons, openweather, gnomestatspro, system-monitor, gTile, muti monitors add-on, sound input & output device chooser

I use some programs that use config files that I have set up in my ubuntu_hacks repo

sudo apt install zsh terminator guake tmux -y

• install and setup vim with ./setupvim.sh in repo

• run the following line to install oh-my-zsh

sh -c "$(curl -fsSL https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"

• copy the .zshrc file into the home directory

• then run to change shells to z shell

chsh -s /bin/zsh $USER

• you will need to log out for this to take effect

• also don't forget to change the ros sourced stuff from devel/setup.bash to devel/setup.zsh

• follow README instructions to set up terminator

copy guake.desktop into autostart with

cp /usr/share/applications/guake.desktop ~/.config/autostart/

• guake has an issue in ubunty 18.04 apt repo that causes it to crash when trying to exit. this is the fix It's a Python indenting issue. https://github.com/Guake/guake/commit/f8699b4be6c058fd58a33a1d783cd404e9076b0e

  • In current 18.04 package (guake 3.0.5-1), it's this file (line 1420):/usr/lib/python3/dist-packages/guake/guake_app.py (it wont be fixed in the apt repos)

clone necessary repos they can be found here.

• Dont forget to follow the readmes in the repos to set up correctly

• for java to work right in ubuntu 18.04

sudo apt install openjdk-8-jdk openjdk-8-jre

• add these lines to you .bashrc or .zshrc

export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
export PATH=$PATH:$JAVA_HOME/bin

This is the resource for developer environment instructions

this adds slacke to the apt repos and adds it to start on boot

wget https://downloads.slack-edge.com/linux_releases/slack-desktop-4.0.2-amd64.deb

sudo apt install ./slack-desktop-*.deb

cp /usr/share/applications/slack.desktop ~/.config/autostart 

This guy set up a ppa to get the latest so they just install and update with apt To use, call this to add the repos

curl -s https://s3.eu-central-1.amazonaws.com/jetbrains-ppa/0xA6E8698A.pub.asc | sudo apt-key add -
echo "deb http://jetbrains-ppa.s3-website.eu-central-1.amazonaws.com bionic main" | sudo tee /etc/apt/sources.list.d/jetbrains-ppa.list > /dev/null

sudo apt-get update

• then install them

sudo apt install clion intellij-idea-ultimate pycharm-community

then for intellij and pycharm when you set them up add the link to run from command line.

To get the clion.desktop to build with ROS enabled. add this to the ~/.profile

NOTE: This isnt working all the way for me, maybe a zshell thing?

source /opt/ros/melodic/setup.bash
source ~/workspaces/anansi_ros/devel/setup.bash --extend

I had a problem getting my CLion to build right in debug mode (breakpoints werent really working) I eventually got it to work. I think it was looking at the normal ROS executables instead of the ones that clion makes. I think what fixed the problem is that I filled in the settings -> Build, Execution, Depolyment -> CMAKE generation path field with what is already greyed out in there. cmake-build-debug

^^^ This didn't seem to fix the problem all the way. If I ever built the ros one the problem would come back. So far it seems like it works to make the generation path field ../build to point to the ros build then they arent stepping on toes. That may work.

To make the desktop icon source ROS correctly edit the EXEC line of the correct clion.desktop file (mine is in /usr/share/applications/clion.desktop) to say Exec=bash(or zsh) -i -c "/path/to/clion/bin/clion.sh" %f

this was one of the build flags -DCATKIN_DEVEL_PREFIX:PATH=/home/jacobolson/workspaces/anansi_ros/devel but clion just started acting strange. maybe an update thing? so I am removing it to try that, and I am trying to go back to building in its own build foler rather than ros

I found out that something in my system wanted clion to be launched from bash. (probably the ROS plugin that I installed) so that is what was breaking it.

This adds the stable release to apt so it will install and update with apt

curl https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.gpg

sudo mv microsoft.gpg /etc/apt/trusted.gpg.d/microsoft.gpg

sudo sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/repos/vscode stable main" > /etc/apt/sources.list.d/vscode.list'

sudo apt update

sudo apt install code

pip install ipython pyqtgraph --user

also use the install script in the dronehunter_analysis_tools repo for those to all work
