I have this strange problem in Ubuntu LTS 18.04

I opened Ubuntu System Monitor and it looks like in the picture.

I didn't do anything special ... just installing updates. I don't know which updates was...or the day that happened?

I wanted to see the using space in system monitor...and I realized that it's mess.

The same issue seems to have the calculator.

Any ideas what could cause this ?

The system is working fine...and didn't see this problem in other apps.

  • You gave no info at all. I have normal text in my SM. We can't guess what you did with your system. – Pilot6 Feb 12 '20 at 13:16
  • I did not do anything.....only update the system. – calin24 Feb 12 '20 at 13:17
  • How can i reset the config for the system-monitor ? – calin24 Feb 12 '20 at 13:18
  • That's typically something you'd see with a missing font, but it's not clear to me how you could tell which one. I'm seeing the same thing, FWIW. – eggsyntax Feb 17 '20 at 20:51

    Does this answer your question? [Only squares instead of letters and numbers are displayed in my calculator and other apps in Ubuntu 18.04](https://askubuntu.com/q/1103560/) – karel Jun 13 '20 at 10:59

I recently resolved this problem by simply deleting all files from home/.cache/fontconfig directory.

If you used snap, uninstall it via sudo snap remove gnome-calculator, and reinstall it via sudo apt install gnome-calculator. It should help you with this issue.
