posted Jan 16, 2021, 4:47 AM by Chris Franklin

So the idea was to allow gaming via steamlink, Moonlight or rdp. The spare GPU is a Nvidia GTX 970.

Proxmox - Install megacli

posted Jan 5, 2021, 5:16 AM by Chris Franklin

This script simply installs the repo for hwraid.le-vert.net and then megaclisas-status and megacli packages.

setup_megicli.bash

#!/bin/bash

_WGET=$(which wget)

if [ $? -ne 0 ]; then

apt update

apt install wget -y

fi

$_WGET -O - https://hwraid.le-vert.net/debian/hwraid.le-vert.net.gpg.key | apt-key add -

if [ $? -eq 0 ]; then

cat <<EOF>/etc/apt/sources.list.d/megacli.list

deb http://hwraid.le-vert.net/debian buster main

EOF

fi

apt update && apt install -y megaclisas-status megacli

Proxmox - Install Chrome

posted Jan 5, 2021, 5:14 AM by Chris Franklin

This script installs chrome and allows it to run as root.

setup_chrome.bash

#!/bin/bash

_WGET=$(which wget)

if [ $? -ne 0 ]; then

apt update

apt install wget -y

fi

$_WGET https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb -O /tmp/google-chrome-stable_current_amd64.deb

if [ $? -eq 0 ]; then

apt install -y /tmp/google-chrome-stable_current_amd64.deb

if [ $? -eq 0 ] && [ -e /tmp/google-chrome-stable_current_amd64.deb ]; then

rm /tmp/google-chrome-stable_current_amd64.deb

fi

# fix root access to chrome

sed -i.backup 's/exec\ \-a\ \"\$0\"\ \"\$HERE\/chrome\"\ \"\$\@\"$/exec\ \-a\ \"\$0\"\ \"\$HERE\/chrome\"\ \"\$\@\"\ \-\-user\-data\-dir\ \-\-test\-type\ \-\-no\-sandbox/g

Proxmox - Install Desktop

posted Jan 5, 2021, 5:12 AM by Chris Franklin

This script will install a light weight GUI (xfce), disable the extra power settings (sleep, suspend, hibernate) and allow root to login to the gui. This along with a browser helps simplify tasks that need to be done while your on/at the host itself.

setup_xfce.bash

#!/bin/bash

apt update && apt install lightdm xfce4 gpm xfce4-terminal --no-install-recommends -y

if [ $? -eq 0 ]; then

systemctl set-default graphical.target

fi

# Allow root

sed -i.backup 's/^minimum-uid/#minimum-uid/g' /etc/lightdm/users.conf

# Disable all power settings.

systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target
