Here : https://bugs.freedesktop.org/show_bug.cgi?id=96312 some people said this is caused by a "slow compositor" . In my case, it seems to me, these log entries are probably caused by a Xorg process running with 100% cpu blocking the UI for ~ 1 minute. This happens after animations played (e.g. progressbars), window resizing, scrolling, when I have many GUI apps open. I am still investigating.
My system: nvidia driver, 2 old GPUs, 18.04 with gdm3+Xorg -- 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/1588009 Title: "libinput bug: timer offset negative" keeps coming up in syslog To manage notifications about this bug go to: https://bugs.launchpad.net/libinput/+bug/1588009/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
