Description of problem: After you move a "sandbox -X" window to another Gnome 3 workspace with the keyboard shortcut, the mouse and keyboard are stuck in the sandbox window, with no obvious way to liberate them or switch Gnome activities. Version-Release number of selected component (if applicable): $ rpm -q policycoreutils gnome-shell policycoreutils-2.1.13-59.fc18.x86_64 gnome-shell-3.6.3.1-2.fc18.x86_64 How reproducible: Consistently Steps to Reproduce: 1. $ /usr/bin/sandbox -X -t sandbox_web_t /usr/bin/firefox 2. Hold Ctrl, then hold Alt, then hold Shift, then press Down, then release those keys, to move the sandbox window to the next workspace. 3. Try to move the mouse outside the sandbox - you can't. 4. Try to bring out Gnome's mode by pressing the windows key - you can't. I looked at "man sandbox", but I did not find clues about how the mouse gets stuck or how to release it. Actual results: It is not clear how to release the mouse and keyboard from the sandbox X window. Expected results: It should be clear how to release the mouse and keyboard from the clutches of the sandbox X window. Additional info: When the mouse isn't captured by the "sandbox -X" window, Gnome's Alt-Tab mode describes the "sandbox -X" window as Xephyr. "man sandbox" does not mention Xephyr. "man xephyr" does not mention mouse capture or release. I did a web search for 'xephyr let go' and found a page that recommended Ctrl-Shift, which resolves part of the mystery of how the mouse got captured. To release the mouse from "sandbox -X", Ctrl-Shift sometimes works and sometimes does not, or requires repeated attempts. Sometimes it seems that Ctrl-Shift isn't working but Ctrl-Alt-Shift (the same modifiers I used with Gnome to move workspaces) is successful, but I cannot distinguish whether Alt is significant or whether one more try without it would have done just as well. At any rate, whatever the right way to release the mouse from "sandbox -X" is, it should be clear and obvious.
Changing release to 18. This was observed in Fedora 18.
Fedora 19 exhibits the same behavior, except that sometimes the workspace switch results in the mouse being captured and sometimes it does not. Changing release to 19. $ rpm -q policycoreutils gnome-shell policycoreutils-2.1.14-46.4.fc19.x86_64 gnome-shell-3.8.3-3.fc19.x86_64
THis is most likely an issue with Xephyr.
The problem persists with Fedora 20
This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '20'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 20 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
