Description

The previous version of xkeyboard-config included the key combinations to clear and/or kill grabs in the default keymap. This enabled users to get around screen locks that use grabs to prevent input to other applications (e.g. gnome-screensaver). This update moves the definition of the key combinations to a XKB option that must be explicitly enabled by the user.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
