While searching installation of lxqt I found apt install command for lxqt-sudo | gksu, xfwm4 | x-window-manager, firefox | www-browser. What does this commands mean? What is the difference with respect to only (apt install) lxqt-sudo, gksu, xfwm4, firefox.

It seems very basic, but unable to grasp. Can someone explain?

  • I suspect they mean use lxqt-sudo OR gksu as they do pretty much the same thing, just call different toolkits to accomplish the goal. Likewise xfwm4 (xfce's window manager) OR x-window-manager (debian use xfwm4 where as Lubuntu use openbox). You should provide a link to where you are asking about, as I'm somewhat confused.

  • What is your goal? Do you want to install the LXQt desktop on your system? What is your system currently?

  • Well, I find the two lead developers there to be pretty frank and blunt :) Could you please clarify your question? What are the exact commands you issued and what were the complete responses in the terminal. Please use copy/paste [between code tags](markdown formatting) to provide the information.

Pipeline character, | indicates OR, i.e., either of the two lxqt-sudo and gksu can be used. Similarly, xfwm4 or x-window-manager and firefox or www-browser.
