[Pkg-virtualbox-devel] Bug#810257: virtualbox-qt: Keyboard capture doesn't

[Tim Bagot]

Package: virtualbox-qt
Version: 4.3.18-dfsg-3+deb8u3
Severity: normal

Dear Maintainer,

To reproduce:

1. Capture the keyboard for a running guest (or just give the guest
window focus if auto capture is enabled).

2. Press a key combination bound by the host system's window manager
(e.g. Super-Tab).

Expected outcome: The key press is sent to the guest because the keyboard
is captured.

Actual outcome: The key press is processed by the host window manager
as normal.

I would expect keyboard capture to invoke XGrabKeyboard(3), so that all
key events not intercepted by the host kernel or X server can go to the
guest. The lack of this can impair usability of the guest system.

One potential difficulty with an indefinite keyboard grab is that a
screensaver will not be able to lock the screen. x2vnc, for example,
deals with this by releasing its grab after a period of inactivity.
