As suggested by @Daniel, I have removed all extensions and been using default Ubuntu DE all day. Sadly, the keyboard freeze is annoyingly present in default Ubuntu session as well.The workaround fixes the issue as discussed before.
PS : I also removed the Yaru install through Ubuntu Software to make sure that it is not interfering. The freeze is still there, but much less annoying than in the Yaru session. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1807056 Title: Occasional Keyboard freeze Status in gnome-shell package in Ubuntu: Triaged Bug description: https://gitlab.gnome.org/GNOME/gnome-shell/issues/907 --- I am using 18.04 and sometimes, whatever I type does not work. It is as if there is no keyboard connected while I have my laptop keyboard and an external keyboard connected to the machine. I even enabled On Screen Keyboard and tried to type through it. Same result.
