The worst thing is that was done as the same time that wayland moved input management to the window manager.

So, useless desktop except as a browser shell where typing is marginal. > journalctl | grep gnome-shell | grep 'libinput error' | grep 'your system is too slow' | wc -l 7060 > cat /proc/cpuinfo | grep model model : 142 model name : Intel(R) Core(TM) i5-7200U CPU @ 2.50GHz model : 142 model name : Intel(R) Core(TM) i5-7200U CPU @ 2.50GHz model : 142 model name : Intel(R) Core(TM) i5-7200U CPU @ 2.50GHz model : 142 model name : Intel(R) Core(TM) i5-7200U CPU @ 2.50GHz Hardly an underpowered system -- Nicolas Mailhot _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
