    I updated from 15.11 to v20. Before the update, I changed the source list, as mention on the official website. It took to 30min to update via terminal. But now everything is too laggy, and it is unusable. Also, my keyboard is not working for a while, and the dock is missing, every file is locked. Even in the dual boot, some windows's file is locked too. Is there any way to solve it?
