I have Zorin Pro and am just starting using it. I want to add a game. So, I go into Software, then Categories, then Games, and the display shows rectangular fields but there is no display. Each rectangle just has three consecutive periods in the middle of it.
Furthermore, what if I want something not displayed. Is there a way to "tell" Zorin to search for a particular game. I just want to add the Free Cell solitaire game (for now)!
If with “add” you mean installing something and software don't display you can just terminate gnome-software on System Monitor. Kill it if terminating it doesn't do the trick.
Just install Synaptic Package Manager, go to the games section or just search for Soliltaire. The most common one on any GNU/Linux distro is AisleRiot Solitaire.
When you open Software, you will see at top left corner an icon for your search. Click on it and it will open a search box. Type in Games - solitaire and you will get a stack of games to choose from.
When opening software, just start typing. The search gets focused automatically. Alternatively you can hit the search button on the top left of the window when opening software.
