How can I find and modify an application launcher in 18.04 because tuxmath seg faults in fullscreen mode?

  • 772

This was happening in 16.04 but I was hoping that an upgrade to the latest everything would fix it. I installed tuxmath using "apt install" and it shows up in the Applications menu so I added it to my favorites and now have an icon in the bar. However when I click the icon the program starts to work then crashes just before the menu items appear. When I run from a command line the output is 

libpng warning: Interlace handling should be turned on when using png_read_image
Segmentation fault (core dumped)

I find that if I run in windowed mode everything is fine, but I really need to modify the launcher for the kids. How do I add the -w to the command initiated by the icon in the launcher?

    You should find it in /usr/share/applications/ or in ~/.local/share/applications/.

    It is generally not recommended to modify files in root directory. If an associated package gets updated the file will most probably be overwritten.

    So if you find the launcher in /usr/share/applications/, first copy it to ~/.local/share/applications/. Open the copied file with a text editor and -w to the Exec= line.
