I want to install a completely minimal GUI on my server. I only need to run a web browser (Firefox or Chromium). Will I get less applications by installing lxde-core or lxde? I tried these packages without install recommends but the desktop environment just doesn't start after reboot. Only lubuntu-desktop works without install recommends.
I was able to install LXDE in Ubuntu 20.04 with only a few apps.
sudo apt-get install lxde xorg lxdm --no-install-recommends
Make sure to choose
lxdm as the default desktop manager so you'll get a minimal login prompt. Note that lock screen doesn't work with this. I recommend to use it with VNC.
