Nikolay, First, background: I am not a xorg developer, but I develop the XKB library used by most Wayland compositors (xkbcommon). The behavior there is the same.
IMO it is worth having a discussion about the behavior. A nice thing about XKB is that it has a specification. It is easier to discuss behavioral changes against a spec than hard-to-understand X code, or 150 comments bugs. Therefore, my proposal for you (or anyone else who is interested in changing the behavior) is to provide a patch against the spec. Even if the actual spec will never change, I still think that a clear proposal, which also considers possible side effects, is the first step forward here. The current spec and the most relevant section is here: https://www.x.org/releases/current/doc/kbproto/xkbproto.html#Key_Actions The current source for the above spec is in the kbproto repository here: https://cgit.freedesktop.org/xorg/proto/kbproto/tree/specs/ch06.xml?id=kbproto-1.0.7#n586 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/36812 Title: Keyboard layout change on hotkeys press instead of release and do not work well with shortcuts Status in gnome-control-center: Unknown Status in X.Org X server: Confirmed Status in gnome-control-center package in Ubuntu: Invalid Status in xorg-server package in Ubuntu: Fix Released Bug description: This is a bug about shortcuts mapped to combinations which include each other. For example, if we have Ctrl+Shift (for keyboard layout) and Ctrl+Shift+N (to open a new terminal), then we are practically unable to use the second shortcut; this is what happens: Ctrl press (nothing happens) Shift press (keyboard layout change) N (a simple N appears, since a shortcut has already fired) The expected behavior is to fire shortcuts on the release (not on press) of the special keys (ctrl,shift,alt, etc) which is also how Windows behave. This is a serious problem for bilingual layouts, typically using Alt+Shift or Ctrl+Shift for keyboard layout change. For users being affected by this problem, the easiest solution for now is to add this PPA in your repositories: https://launchpad.net/~oded-geek/+archive/xorg-patches Practical summary of this bug for ubuntu developers (since reading 120 comments is impractical for most): This problem is a really old (since 2004) issue of the xkb part of xorg; the main discussion was made upstream in freedesktop-bugs #865. There has been a patch from Ilya Murav'jov for upstream (#55), and attached here (#61). Upstream xorg has refused to apply the patch, mainly because it "explicitly contradicts the (xkb) spec" (#84, #91). This patch has been reported to work for many people without any problems, and there is also a PPA by Oded Arbel (#95) where he maintains a patched version of the ubuntu xorg. The proper resolution of this bug would be to apply this patch to the upstream xorg, or at minimum to the official ubuntu xorg package.
