Keyboard unresponsive after suspend and resume (19.10)

[Matthias]

Since two to three weeks, my keyboard sometimes becomes unresponsive after wake up from resume. Often it is associated with an @ sign on black background, when the machine is resumed.
After that I am back in the desktop. Trackpad and everything works, but the keyboard doesn't.

This is on a 2009 macbook pro running uptodate 19.10.

[Daniel van Vugt (vanvugt)]

When you say the trackpad still works, can you also click on things and get them to respond?

If you get a response to the trackpad then this is probably a keyboard bug to be assigned to the kernel. If you get no response from the trackpad and can only move the cursor then this is probably a gnome-shell crash under Xorg. Since you seem to have the 'wayland-session' tag here already I will assume the former...
