Run GUI Application from web-based terminal emulator ubuntu18.04/Jupyter Notebook

I have installed a fully-functional terminal emulator in an IPython/Jupyter notebook. This is useful for notebook environments that don’t provide shell access. The terminal is used inside the browser. All commands are executed correctly. But, there is a problem with opening a GUI application from the web-based terminal. Web-based terminal screen

For instance, executing xclock inside the terminal does not open the application window. Is there any feasible solution to open GUI application from web terminals?

How can I install more than one Desktop Environment in my Ubuntu without damaging the system?

How can I install more than one Desktop Environment in my Ubuntu without damaging the system? I want just to try those desktop. I know I can install them by sudo apt install kubuntu/xubuntu/lubuntu-desktop . But it will remove my existing Desktop Environment, right? I want that whenever I want to change the Desktop Environment, I will log out and log in to that. Is it possible to do that? Don’t say to download ISO image of Kubuntu, Xubuntu, Lubuntu as I want to see them in my current installation.

Screen is shifted with Xubuntu

Screen is shifted with Xubuntu

I have a computer with a Ryzen 5 2500U CPU with RX Vega graphics. I created a Xubuntu 20.04 installer and booted it, but now I have this really weird distortion on my screen, where different vertical parts are shifted to the side. The mouse pointer isn’t shifted, so it’s really difficult to click on anything. How do I fix this?
