This is not strictly a fvwm question, but maybe there is a fvwm solution
to it, or I can be directed to a forum where this is on topic.
I'd like to use only PART of my X server screen as it were the full
screen.
I'm aware of an utility like xrandr, but this changes temporarily the
resolution in a fake way using still the entire screen.
The background of my question is as follows.
I have available a laptop (not the machine where I usually work) which I
intend to connect to a videoconference device. Then I want to show an
acroread PDF presentation and a firefox demo, ideally in full screen mode.
On the laptop I run Suse Linux and use fvwm.
The point is that some part of the PC screen does not appear on the
videoconference TV set (and is NOT trasmitted outside as well !). Say in
the most favourable hypothesis that the entire vertical span of the PC
scren is replicated on the TV and transmitted, while some 200 pixels on
the right fall off screen of the TV.
I've spent one afternoon testing all possible sensible combinations of
laptop screen sizes (Linux SAX2 and even Windows) with the settings of the
videoconference device. Then I spent 4 more hours in a videoconference
with the manufacturers of the device. The conclusions were that :
- if the laptop is connected directly to the TV, there is no truncation
(the XGA signal from PC is OK with the TV)
- if a remote site sends it PC screen to the videoconference device
it is not truncated (the remote videoconference device sends correct
XGA)
- there is some mungling which our videoconference device does to the
XGA stream from the PC before dispatching it (to the TV and outside)
- they seem to suggest withdrawing the device to factory for checks
and reconfiguration.
These times are not consistent with my needs (a demo scheduled in a couple
of weeks). I have of course a possible workaround which is :
- arrange a test with the real site where the demo shall be seen
- manually resize the acrobat and firefox windows so that they occupy
a fraction of the laptop screen
... and this fraction is exactly the part replicated to the
videoconference
... but then there will still be needed adjustment to remove the window
manager decoration and various service buttons which are usually absent in
full screen mode.
What I'd like to do is to "wrap" my X-session in one application which
could act as an X server with a reduced screen size.
Does such wrapper exist (ideally within fvwm or at least within Suse) ?
Any hints will be much appreciated
