[Desktop-packages] [Bug 1777708] Re: Desktop briefly becomes unresponsive when receiving a keypress from a different device/mapping than the last keypress (in Xorg)
I'm facing the same symptoms. First time I realized I have this issue was when playing a game on Stadia through Chrome/Chromium. I am using a special hybrid joystick (movemaster.biz) to replace my keyboard, which consists of two parts. Both devices are connected via usb and are recognized as usb hid keyboards. When steering with the grip of the device and only pressing buttons on the same device everything is okay. But as soon as I press a button on the extension there is a litte lag or stutter/freeze. I thought it would be an issue with the browser and blamed Chromium, as I haven't had any issues with games played locally. But now I had the same issue with Star Wars Battlefront (from EA) played through Steam + Proton. The output of journalctl showed the same overwriting existing binding of keysym errors as described here: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1857392 That report leads to this report, and from here I got to https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/1858#note_818548 describing a workaround with altering libmutter. I tried that workaround on Ubuntu 20.04.3 LTS, where I at first wasn't able to successfully biuld mutter/libmutter, but it helped to disable the tests by editing debian/rules and add export DEB_BUILD_OPTIONS=nocheck. Installing the altered lib and rebooting didn't get rid of the problem though. Unfortunately the blog post from Osvald doesn't seem to be reachable as the https certificate was revoked. As the freeze happens despite the workaround, I'm not sure if it's the same issue though. Any help would be appreciated as this behavior totally ruins the experience. -- 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/108 Title: Desktop briefly becomes unresponsive when receiving a keypress from a different device/mapping than the last keypress (in Xorg) Status in GNOME Shell: Unknown Status in Mutter: Unknown Status in gnome-shell package in Ubuntu: Confirmed Status in mutter package in Ubuntu: Confirmed Bug description: I'm running Ubuntu 18.04 and Gnome 3.28.1 with all the latest updates from the repos.

I was facing this bug in Pop OS 21.04 when changing keyboard, pressing media keys in laptop (volume, brightness, etc) or using a mouse with configurable hotkeys. The delay was very long. After I worked on Pedros' solution written above (scroll lock key), the delay reduced significantly. But it was still present. If not gaming, barely could notice it. The solution that worked for me was this workaround from "Wiggy boy" https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/1858#note_818548 Now the delay is completely gone -- 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/108 Title: Desktop briefly becomes unresponsive when receiving a keypress from a different device/mapping than the last keypress (in Xorg) Status in GNOME Shell: Unknown Status in Mutter: Unknown Status in gnome-shell package in Ubuntu: Confirmed Status in mutter package in Ubuntu: Confirmed Bug description: I'm running Ubuntu 18.04 and Gnome 3.28.1 with all the latest updates from the repos.

[Desktop-packages] [Bug 1777708] Re: Desktop briefly becomes unresponsive when receiving a keypress from a different device/mapping than the last keypress (in Xorg)
I'm here to say that I'm having the same issue. Until this evening, I was using Debian 10 with KDE, but I installed Ubuntu 20.04 a few hours ago. I use a laptop with a external keyboard connected on it and my laptop have a numeric keyboard and my external keyboard don't, so I always use the laptop keyboard to insert numbers. However, each time I swap the keyboard, my computer frozen. Also, I have a mouse with several buttons and two of them are configured as "PgUp" and "PgDn" because I find it more practical over there. However, unfortunately, I can't use it properly because the computer crashes every time I press a button. However, I think it's worth mentioning that mouse buttons that belong to the mouse (like click and scroll) don't have this problem. In short, if I switch keyboards, whether it's laptop, external or mouse buttons, my computer freezes. -- 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/108 Title: Desktop briefly becomes unresponsive when receiving a keypress from a different device/mapping than the last keypress (in Xorg) Status in GNOME Shell: Unknown Status in Mutter: Unknown Status in gnome-shell package in Ubuntu: Confirmed Status in mutter package in Ubuntu: Confirmed Bug description: I'm running Ubuntu 18.04 and Gnome 3.28.1 with all the latest updates from the repos.
