I'm here to say that I'm having the same issue. Until this evening, I was using Debian 10 with KDE, but I installed Ubuntu 20.04 a few hours ago.
I use a laptop with a external keyboard connected on it and my laptop have a numeric keyboard and my external keyboard don't, so I always use the laptop keyboard to insert numbers. However, each time I swap the keyboard, my computer frozen. Also, I have a mouse with several buttons and two of them are configured as "PgUp" and "PgDn" because I find it more practical over there. However, unfortunately, I can't use it properly because the computer crashes every time I press a button. However, I think it's worth mentioning that mouse buttons that belong to the mouse (like click and scroll) don't have this problem. In short, if I switch keyboards, whether it's laptop, external or mouse buttons, my computer freezes. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1777708 Title: Desktop briefly becomes unresponsive when receiving a keypress from a different device/mapping than the last keypress (in Xorg) To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1777708/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
