Developer Workstations with Proxmox VE and X11

Introduction

Proxmox VE is primarily used as virtualization platform with NO additional software installed. In some case it makes sense to have a full desktop running on Proxmox VE, for example for developers using Proxmox VE as their primary workstation/desktop.

Installing additional packages could lead to a hardly upgradeable system and is not supported from the Proxmox support team and therefore only for expert use.

Install a standard Proxmox VE system

Just install the standard Proxmox VE, following this guide: Installation

Custom installations: Install Proxmox VE on Debian Buster

Install X-windows

Update your repository and system by running:

apt-get update && apt-get dist-upgrade

I choose xfce4 desktop as this a lightweight desktop environment. If you prefer another one, just replace xfce4 with lxde, gnome, icewm, kde, ...

apt-get install xfce4 chromium lightdm

Start X-windows

Before starting the x-windows, create a normal user with:

# adduser newusername

Start the login manager:

systemctl start lightdm

or just reboot.

Optional: Mate Desktop

Install Proxmox VE as described above.

install from Debian repository.

apt-get install mate chromium lightdm

Optional: NVidia Drivers

# nouveau was faulting system. blacklist or unload driver 
# lspci -k |grep VGA
# add 0000: to unbind driver.
# echo "0000:24:00.0" > /sys/bus/pci/drivers/nouveau/unbind
