While working on my laptop, all of a sudden a logo(see the screenshot given in the linkhttps://drive.google.com/file/d/105s...OVJCKdv3u/view) appears on my screen. My keyboard stops working whenever this logo appears. The logo appears on its own. What should I do?
I use ubuntu.
My laptop is:
LENOVO ideapad 310

how long does it take before the logo disappears again?

wild guess: your hardware is not fast enough to support the super-heavy bloat gnome desktop environment.

Obviously something is taking up so much of your computer's resources that it has to stop you inputing more data. I'n not so sure that it's too weak to run the Gnome desktop, though. It may not be the most powerful of computers, but it's capable of running Windows 10. Also, I see from your screenshot that you were only using a text editor.

Somewhere in your menu there should be a system monitor that will show you all the processes running and how much CPU time and RAM they're using. Run that with nothing else and see if there is any process that's using more than, say, 20% of CPU activity. If so, tell us what it is.

It would also help to know exactly CPU we're dealing with — tell us the result of this command:
And what distro are you using: Ubuntu?

I'm guessing a missing icon resource..
Try another theme. IDK cpp, sorry. they come with "logos" or "icons"?
all text. and hella short.
