I am running Ubuntu 22.04 while it worked well until I manually ran sudo apt upgrade -y --allow-downgrade some day. (I forgot about the upgrade details though). After that I found:

  1. My Prt Sc key no longer works
  2. All the file uploads will cause the application to freeze, it happens on Chrome, Brave Browser and Slack and some other applications.

What should I do to fix this problem? Is this something related with gnome-shell? Thank you very much!

I had the same issue and I think I found the solution.

Try changing chrome://flags/#ozone-platform-hint to "Wayland" and relaunching Chrome

EDIT:

otherwise, try launching Chrome from the CLI like that

google-chrome --enable-features=UseOzonePlatform --ozone-platform=wayland

  • Thank you sir! But mime seems to be a global issue not only happens with Chrome. Anyway I just switched to another desktop environment instead of GNOME so it solved my problem. But thank you very much – Min Ju Apr 26 '22 at 11:35

I have found the answer in this bug report: link

All you need is to install this package:

sudo apt install xdg-desktop-portal-gnome

It has worked for me.
