Subject: [PATCH] disable default grab sequence in kiosk mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Hotkeys should be disabled in kiosk mode. However, if no
"release-cursor" hotkey is specified, the default Ctrl+Alt
grab sequence keeps functioning even in kiosk mode.
That's because it's based on the spice/vnc functionality instead
of on the accelerators in virt-viewer.
That's especially problematic with spice, because the grab
sequence releases both the cursor and the keyboard. Thus the user
can escape from kiosk mode by pressing Ctrl+Alt followed by
Alt+Tab, for example.
