I took the following steps: * Installed Ubuntu 17.10.1 * Added an extra keyboard layout * Updated the packages * Rebooted
No additional layout switch shortcut so far. Then I run "update-manager -d", and when it was installing the new and upgraded packages, a window for keybord configuration popped up and I was prompted to select method for switching between "setting for national and latin" (see attached image). Alt+Shift was pre-selected. I found no way to skip that setting, and clicked the "Forward" button. Result: $ cat /etc/default/keyboard XKBLAYOUT="se,us" XKBVARIANT="," BACKSPACE="guess" XKBMODEL="pc105" XKBOPTIONS="grp:alt_shift_toggle,grp_led:scroll" So there it is. And at first login those XKBOPTIONS values were imported by dconf (as expected). I still can't tell which package is the culprit. Changed to ubuntu- release-upgrader for now, since it's probably closer to the truth than gnome-shell. In any case the upgrade behavior in this respect needs to be reconsidered, at least for desktop upgrades. No program should make assumptions and gratuitously set XKBOPTIONS in /etc/default/keyboard, especially since g-c-c does not offer a way to modify it later. (Is there a reason for the upgrader to mess with keyboard configuration at all?) ** Attachment added: "keyboard-config-prompt.png" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1762952/+attachment/5127164/+files/keyboard-config-prompt.png ** Package changed: gnome-shell (Ubuntu) => ubuntu-release-upgrader (Ubuntu) ** Changed in: ubuntu-release-upgrader (Ubuntu) Importance: Undecided => High -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1762952 Title: Alternative shortcut for layout switching Alt+Shift unexpectedly set by default To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1762952/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
