On Ubuntu 20.04, I have similar problem. Actually, I met this problem since 19.10, however in 19.04, it was fine.
My default GUI env is GNOME, and I switched to KDE recently but the problem still occur sometimes. This problem is a little bit different from other people in these aspects. 1. This problem not only happen in gnome-shell. it happens almost every where, especially when you type in a textbox. For example, in chrome and pycharm, I met the similar problem. Which indicates that this bug is a general problem. 2. When my keyboard is freezing, I cannot type in the TEXTBOX. however, other part of keyboard still work such as Capslock and Super(Meta) button etc. Simply speaking, when the keyboard is freezing, I can still push META button to present all windows, however I CANNOT type anything to input in the TEXTBOX. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1807056 Title: Occasional Keyboard freeze To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1807056/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
