Public bug reported: I'm using 2 keyboards for gaming * and when i press a key on one of them, then press a key on the other (which happends some times per second, it's not rare at all) the game freezes a bit, something like 100ms i guess. It's really incapaciting, i can't use XFCE as my daily DE because of this bug
I'm pretty sure this bug comes from XFWM, because when i change it (openbox --replace, for exemple), the bug is gone During my searches about this bug, i found one on Gnome which exactly looks like the one i'm describing : https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/1858 It looks like a poor response to MappingNotify event (which indeed happends each time i have the freeze, when i press/release a key on a keyboard which is not the last keyboard which i pressed/released a key) * I don't really use 2 keyboards, but my mouse (Logitech G502), like many mouses with configurable additionnal buttons, is detected as a keyboard by the system, so nearly everytime i press on a mouse button, this bug happends Description: Ubuntu 20.04.2 LTS Release: 20.04 xfwm4: Installé : 4.14.1-0ubuntu1 Candidat : 4.14.1-0ubuntu1 Table de version : *** 4.14.1-0ubuntu1 500 500 http://fr.archive.ubuntu.com/ubuntu focal/universe amd64 Packages 100 /var/lib/dpkg/status I expected no freeze when i use my keyboard or mouse Instead, each time i use my keyboard or mouse, my computer has a small freeze ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: xfwm4 4.14.1-0ubuntu1 ProcVersionSignature: Ubuntu 5.8.0-45.51~20.04.1-generic 5.8.18 Uname: Linux 5.8.0-45-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.20.11-0ubuntu27.16 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: XFCE Date: Thu Apr 1 13:30:45 2021 InstallationDate: Installed on 2021-03-10 (21 days ago) InstallationMedia: Ubuntu 20.04.2.0 LTS "Focal Fossa" - Release amd64 (20210209.1) ProcEnviron: LANGUAGE=fr_FR PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=fr_FR.UTF-8 SHELL=/bin/zsh SourcePackage: xfwm4 UpgradeStatus: No upgrade log present (probably fresh install) ** Affects: xfwm4 (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug focal -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1922230 Title: small freezes when using multiple keyboards To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xfwm4/+bug/1922230/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
