My system freezes for 1-2 seconds every time I need to input a password, most of the times when I start typing on the a new window or dash input and every time when I turn volume up/down through the keyboard. Probably it happens on other situations, but these are the most noticeable ones.
I am investigating it already for a long time and these are the conditions for it to happen:
- Ubuntu 18.04
- Gnome shell
- xorg display server
- Portuguese (Brazil) layout among input sources options
The problem doesn't happen if I: 1. use Ubuntu 16.04 Gnome 1. switch the interface to cinnamon or KDE on 18.04 1. switch to wayland on 18.04 1. remove Portuguese (Brazil) from input sources options
The weird thing is: if I am using English international input source it works well if and only if "Portuguese (Brazil)" is NOT among the options configured - if I add it, the problem happens even if I keep using the english input source config.
My system default language is english - maybe this is causing some kind of conflict. I don't want to use portuguese as system language because some names just get horrible (like "Área de Trabalho").
No useful info on syslog and already tried everything here: Keyboard input lag in Ubuntu 18.04 (looks like a different problem)
Do anyone have any tip that may help? I like cinnamon but not as much as gnome shell...
Thank you very much!
