I would like to install LXDE on my router, but whenever I do it using sudo apt-get install lxde it replaces the default login screen with the LXDE login screen, I would like to install LXDE, BUT keep the command line as the default login.
In my chromebook I have a chroot and to start LXDE on it using startlxde and I want to able to do the same on my server, since I'm working on setting up a SDR based HAM radio station that runs on the server.
startlxdescript probably is. You might want to look on your chromebook with maybe acat $(which startlxde)and see the contents of it. For booting to the Command Line log in after you install lxde see https://askubuntu.com/a/859637/231142 – Terrance Mar 29 '18 at 13:55
