I recently installed Lubuntu 18.10

The other night, while looking at my display settings, I could see something about X render, and GLX (OpenGL). For some reason I decided to click on the GLX option.

Right away my screen was corrupted and I was unable to click on anything. So I launched the terminal and typed reboot or sudo reboot actually. I was able to get back into the Gui, but when I went to check my display properties again the screen again went silly on me, splitting the display in half and not letting me click on anything. All I could do was launch a terminal, ctrl alt t, and once again choose to reboot.

Now lubuntu starts to load up, but once the splash screen with the progress dots goes away, I'm left at a black screen, my cursor, and nothing else. Won't launch the Gui.

What can I do to set things straight again.? Thanks in advance..

    I'm somewhat confused; you start talking about Ubuntu, then switch to Lubuntu before tagging Xubuntu. The X11/GL question is key, but I can't imagine what question you're talking about & mentioning three different desktops/flavors doesn't help.

  • I downloaded what I think was referred to as lubuntu 18.10 My question iis... How can I get back to a Gui desktop. I selected GL as a renderer (X something was selexted) And then my screen went bad, splitting in half, not showing wallpaper or a dock, or letting me click on anything, except to launch a terminal via ctrl alt t From there, I did a sudo reboot, and the machine rebooted. However, after the loading splash screen with the progress indicator dots goes away, rather than put me at a Gui desktop, it just sits at a black screen. Thanks Mar 21, 2019 at 23:03
  • When stuck at the black screen, I can anger, uname - a, and this is what I get... Linux 4.18.0-generic #17- Ubuntu smp Fri Feb 8... etc Mar 21, 2019 at 23:24
  • Are you using Lubuntu 18.10? (thus LXQt) or Xubuntu 18.10? (thus XFCE) or Ubuntu 18.10? (thus GNOME) So far your question is just unclear, and we cannot help you much as we don't even know what you are running. If you have additional information (or wish to clear up your question), please edit the question & add there
