Sorry but I am absolutely confused. I am quite sure that in clone mode I must have the same resolution. I see that the optimal resolution of my tv must be 1024x768 and my monitor LCD must be 1400x900. Could I do panning with this to can see my TV with 1024x768.
This is may xrand:

it! That's one reason I didn't spot what Tassilo Horn (referred to below
as TH) has now mentioned, that your use of the term "virtual desktops"
wasn't quite what I was thinking. The other was the lack of any real
details of what you were trying to do.
TH mentions the problem with differing resolutions in clone mode, that the
lower resolution one then shows only a part of what the larger one shows,
but xrandr is flexible enough to work around it using panning, if you
wish. Of course, panning has its own issues, the biggest one being that
it takes some getting used to, and it makes many folks a bit dizzy and
disoriented until they do. Some folks never adapt, but used in a limited
fashion, I find it useful, tho I'd not like to use it all the time as my
main work mode.
TH has reasonably basic script that looks like it should work fine in
bash. It demonstrates the basic ideas, tho as he points out, doesn't
quite do what you wish, clone mode.
My script is a bit more complex, using a few more of the xrandr features,
but still doesn't do exactly what you want, and I've not abstracted it to
the point of general use yet, tho it should be reasonably clear what needs
changing.
You'll also want to refer to the xrandr manpage. Hopefully, it's
installed on whatever distribution you run. You can load it with "man
xrandr", run in konsole. That gives you an overview of the command and
its command line options, explaining what each one does.
I also have an ATI card, now a Radeon hd4650, tho I used the same script,
with a couple slight changes (basically, the new card has two DVI outputs,
DVI-0 and DVI-1, the old one had VGA-0 and DVI-0, so I had to change that
in the script, you'll probably need similar changes, among others), on my
old Radeon 9200. So the script should work well across all of them.
The other detail to consider is that I'm running the xorg native xf86-
video-ati driver, configured in xorg.conf to use radeon. If you're using
the proprietary frglx, things may or may not work the same. You'll also
want a reasonably new xorg and driver. RandR panning was only added in
randr 1.3, IIRC, so for the xf86-video-ati 6.12 series (I'm running
6.13.0, now). You'll want xrandr 1.3 series and a reasonably new xorg-
server as well, tho I don't know what's required there. (I'm running 1.8
but 1.7 worked, IDR whether 1.6 and 1.5 did, or not.) That's of course
assuming you want panning. If you can do without panning, xrandr 1.2 and
older versions of the other xorg related components may be fine, tho there
was a bug in I believe the older xf86-video-ati drivers, that caused
xrandr not to work as documented in terms of the --pos option, which I
didn't need any more once panning worked, since I could just pan to where
I wanted to be.
Looking at the xrandr manpage, you might be interested in the --scale
option. I've never used it here, as it wasn't what I needed, but it may
well fix your problem without bothering with some of the other options
that I use.
Now explaining my script:
My setup is two LCD monitors, same brand and model, so identical size (24
inch diagonal, 518x324 mm, according to the xorg log) and native
resolution -- 1920x1200. Like TH, I create a bigger total desktop with
them, not cloned. Unlike TH, I stack mine, doubling the vertical
resolution for 1920x2400 total resolution at native. The script assumes a
top/bottom orientation in its variable names, etc, but I've begun the
process of abstracting the values into variables and from there into a
config file, so it shouldn't be too difficult to change them, as
necessary. As the comment in the script suggests, you'd make the changes
in three places, the variable values at the top, the help text, and the
case statement.
You'll find the actual script copied in just below my sig. It's designed
so it can be run from a konsole session for debugging purposes, thus the
xrandr --verbose option.
Once you get a script setup and working when invoked manually, if you
wish, we can talk about invoking it with a hotkey and/or adding it to the
applications menu, then.
