presentation. So as long as this feature is missing, I would like to
have cloned displays, both in there native resolution, which means the
content has to be rendered twice, once for each display. Windows drivers
for some laptop graphic chips allow this, but I don't know of a single
solution to make this happen with Linux. IMHO, this is due to the x.org
drivers not allowing this.

Why do we assume that one instance of the running program must be cloned
to both screens in order to show similar images on both?

Is it possible to run two instances of an application (or different,
similar applications), one on each non-cloned, non-Xinerama
configuration. Could the one on the laptop pass a message to the other
one about what image to display on the projector?

There could be an option of using thumbnails on the laptop, and not on
the projector. Both could have the same display, but at different
resolutions.

On my dual screen desktop, the CAD benefits by very high resolution.
Text editing or web browsing on the other doesn't benefit from such high
resolution. Neither Xinerama nor clone are useful for this. On SuSE 10.1
I have been hand editing xorg.conf to force the option I need.

If Thunderbird is on one monitor and Firefox on the other, then URL
links imbeded in emails do not work to completion; an error message says
that we can NOT run the requested web page because there is an instance
of the browser on the system. If I knew how, I would have Thunderbird
message the browser on the other monitor and pass the imbeded link so
either a new page or a new tab opens on the running browser.

The (new ?) application wanted for the laptop/projector in a speaker's
situation is maybe not so different than mine. An Amiga might have done
this with Arexx scripting.



I just noted that *maybe* you are referring to drivers that do the
scaling for the laptop on the graphics chip (instead of letting this as
an option to the display) and might do better filtering here.

The availability of such an option is very much dependent on the
graphics driver. I think the nvidia (closed source) and the radeon
driver (open source) both have options to configure something like that.
