Can I make my QT GUI programs run after completely removing unity desktop? I am building a desktop environment on QT. How can I run my program without unity.
Unity isn't a dependency of QT apps in any way that I know of. If your question is "How can I launch a program without Unity?" The answer is this: I wouldn't uninstall Unity at all because you don't need to. First press CTL-ALT-F1. Log in, and type
Basically, this just creates a new X screen, and you can switch back to your main screen with CTL-ALT-F7. To go back to your new X screen, press CTL-ALT-F8. You can create up to 6 X screens at a time, each one corresponding to F7-F12. I hope this answers your question!
