I am using 18.04 on hp Elitedesk with intel i7.
I am currently using unity for the GUI client.
During the transition from different workspaces, the screen freezes all of a sudden. Although there is no apparent trigger. It just happens randomly.
** Some outputs of diagnostic commands **

- On boot, some times (randomly) screen gets blurry like seeing an old monitor through a digital camera.
- Also, some times (randomly) keyboard and mouse doesn’t work at the login window, so I can’t type a password and log in.
I have no clue why this is happening, and I don’t even have idea where to check for potential causes. Any advice will be helpful.
