  1. Thanks for this. Worked perfect on Ubuntu 12.04

  2. I could not get this guide to work. On a clean Ubuntu 13.10 VM, I can’t get nautilus to run. On several fresh attempts, I get a message that a display cannot be opened.

    I tried both of your ‘sudo’ lines of code, and set the display to 0:0.0 but, this didn’t help so I can’t try the rest of the solution.

    Any advice?


    • You mean you can’t open the Nautilus as root? Well, launch a terminal via Ctrl+ALt+T and type in sudo nautilus, hit enter and input password. Does this brings up your browser?

  3. Thanks for the swift response.
    In case it’s important, I don’t find that any of the Ctrl codes you mention do anything when I’m using Ubuntu.

    I just ran sudo nautilus at the command prompt and got:
    (nautilus:1361): Gtk-WARNING **: cannot open display.

    The actual error code may not be the original one, as I have tried a solution or two.

    • Anthony, this is a Virutalbox issue with X. Sorry that I don’t know how to fix it, but you can search it on Google

    • Hey,

      What I did was opened up the terminal and used the command sudo mv LightTable /opt/ and it worked

      Why don’t you try that out

  4. In 13.10 i had to add env UBUNTU_MENUPROXY=0 /opt/LightTable/LightTable as the command to the launcher. Otherwise the menus were grayed out and non responsive.

  5. Hi Ji

  7. Thank you, worked out for Ubuntu 14.04.

  8. Worked like charm on Ubuntu 14.04

  9. salam ( hello )
    it’s doesn’t work on my elementary os (ubuntu base os )
    got :
    /opt/LightTable/ or not found in any of /lib64 /lib/x86_64-linux-gnu /usr/lib/x86_64-linux-gnu /usr/lib64 /usr/lib /lib.

  10. Thanks for the tutorial. Just one question, while I was trying to figure out how to put the icon I created three launchers, two with blank images, and the good one. Do you know how I can remove the other two?

    • Launcher files are located in /usr/share/applications. In terminal run gksudo nautilus to launch nautilus file manager with root privilege. Then navigate to computer -> /usr/share/applications, find out the wrong icon files your created and remove them.
