I had the same situation, first on ubuntu 20.04 and now still on ubuntu 20.10.
I have USB keyboard nad usb mouse. I am using mapping for my USB mouse (btnx-config library) so I can map my button as keyboard keys, I was noticing small freezes but I though it was library problem. But later I wanted to create a simple keylogger from python keyboard library and simple script which always when I press d it also press r in system keyboard. When I did it many times, my computer freeze for few seconds, even minute and this warning occurs in syslog. Is it going to be solve in 21.04? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1777708 Title: Desktop briefly becomes unresponsive when typing on 2 keyboards at the same time To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1777708/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
