I'm trying to install XFree86 and it asks to turn off the display, but I don't know how to do that.

What command do I do this with?

I'm using the latest version of Ubuntu (22.04).

In Ubuntu 22.04, the login/password screen is NOT run by the display server (X or Wayland) -- it's run by the display manager (gdm or lightdm).

When you see that login/password screen, the display server is not running nor even loaded.

Upon a succesful login, the display manager launches the display server and triggers the loading of the entire desktop.

That's one reason why loading your desktop takes a moment. Your whole desktop stack is loading.

Upon logout, the display server is stopped. That's why you return to the login/password screen (the display manager).

  • And how do I logout? Sorry for my lack of knowledge, I'm new to Linux. – Atila o Grande Aug 05 '22 at 02:25

  • Okay, but just logout doesn't work for me. I want to turn off Display so I can install XFree86. If I logout this way how can I install it? – Atila o Grande Aug 05 '22 at 16:31

    That's a very ambitious goal for somebody who is "new to Linux," mostly because that project has not released in 13 years; it pre-dates many Ubuntu system components and is unlikely to work for you without hours of expert help. What is the issue you are encountering that leads you to believe that XFree86 is the best solution? – user535733 Aug 05 '22 at 16:42
  • I'm trying to install QJoypad which requires it. – Atila o Grande Aug 05 '22 at 16:50

    qjoypad is in the standard repositories. I doubt it requires XFree86. – ubfan1 Aug 05 '22 at 16:53
  • I suggest opening a new question: "How do I install qjoypad on Ubuntu 22.04?" I suspect you may find the answers to be much less confusing and much more satisfying. – user535733 Aug 05 '22 at 16:55
  • I'm actually trying to build it because here (https://github.com/panzi/qjoypad), in its repository, there's no version already compiled. – Atila o Grande Aug 05 '22 at 17:23
  • The requirement for that version is XWindows (not XFree86). XWindows is already included with Ubuntu -- you select it at the password screen when you login. – user535733 Aug 05 '22 at 17:27
  • I clicked on the top right corner of the Ubuntu desktop and chose Shutdown/Logout and Log Out. So I clicked on the gear icon at the bottom right and it only had Ubuntu and Ubuntu with Wayland options. Remembering that I formatted my PC, then deleted the Lightdm I had installed. – Atila o Grande Aug 05 '22 at 17:53
  • @atila-o-grande The "Ubuntu" choice is the Xorg default (you probably are using Nvidia hardware with the 515 driver to get the Wayland option). – ubfan1 Aug 05 '22 at 18:13
  • You're right about the driver I'm using, but will either option enable Xorg? – Atila o Grande Aug 05 '22 at 18:20
  • Friends, you won't believe it, but I found QJoypad in this link. How silly of me trying to compile it! – Atila o Grande Aug 08 '22 at 06:05
