Please edit your post and change the thread title to one that is specific and informative while still being brief such as "Mouse Glitch/HD Hit Once Per Second" or "No Sound With PulseAudio". A clear, brief, and informative thread title will attract more people with the relevant skills and knowledge to the thread.
Additionally, in the post itself you need to be much more specific as to any error messages that are shown or at what point and why the LXQt spin 'doesn't work'.
Hardware you are using it on would also help pin point what is going on.
Please take the time to read through the posting rules and guidelines. They are there to help you get help:
