<div dir="ltr">yes, thank you Mikhail. I have been "stuck" using the host's screenshot workaround for three years. :) The only issue with that is if you aren't running in full screen, which I don't do anymore since I have a 27" screen now, you have to go in and crop things. I hope "one day" comes soon ;)<br>

Hi Louis,<br>
<br>
Due to the way VBox 3D support is implemented currently, taking
screenshot inside guest may not work, <br>
actually it should work only if guest is using standard 3D/OpenGL
API for screenshot acquisition.<br>
VBox 3D support gets enhanced constantly, so this should be surely
fixed one day I'd say.<br>
For now you can use host's "take screenshot" functionality as a
workaround.<br>

<div>This has
been a long
standing
problem with
VirtualBox
running on Mac
hosts. For
whatever
reason
screenshots on
Linux guests
running Compiz
or Unity or
Gnome3 or
Cinnamon can
not take
screenshots.
All one gets
is an empty
black screen.
I've been told
this is not an
issue for the
Windows or
Linux versions
of VB. As of
today's 4.2.51
version it's
still an
issue. If it
is one of the
things being
worked on
currently of
course ignore
this message.<br>
<br>
</div>
I would
mention the
current
version of
Debian 7 with
Gnome 3 does
actually work
as far as
screenshots go
and I have no
idea why.<br>

<div>Hi.<br>
</div>
<div>Is it the
case with QImage
frame-buffer
too?</div>
<div>I mean by
default MacOS X
host VM uses
Quartz2D
frame-buffer but
there is an
experimental
QImage
frame-buffer
support which
can be used by
trunk VM through
'--rmode image'
passed as
additional
argument to
'VirtualBox
-startvm <vm
name>' like:</div>
<div>VirtualBox
-startvm Ubuntu
--rmode image</div>

<div>Hi.<br>
</div>
<div><br>
</div>
<div>Ok, it seems the screen-shot issue is
deeper than the used frame-buffer type.</div>
<div>Is it 3D related thing? I mean is the
screenshot correct when you are getting it
with 3D turned off for the same VM?</div>
<div><br>
</div>
<div>About error warnings in terminal, you can
ignore these warnings for now.</div>
<div>They are related to new functionality which
is not yet implemented from the GUI side.<br>
