Alex,

thank for your on-going support.

I did end up buying that 1680x1050 TFT  a while ago.  Just like you said
it works fine with the X24.  I run it in Xinerama mode (MergedFB would
of course not work with one screen at 1024x768 and the other at 1680x1050).

The only real "complaint" I have is that when I go to VT 1 and then back
to X the laptops internal display seems to be dropping to 8-bit color.
That of course looks strange.  Did you ever hear about that?  I looked
through the bug tracker but found nothing obviously realted to this.
Any kind of workaround for this?

Furthermore, I have the laptop display on the left and the bigger screen
on the right.  When moving the mouse in the lower left corner of my
external bigger screen and accidentally moving over to the smaller
internal display, I don't return to the original position on the big
screen.  I assume I return about 768 pixels from the top.  This can be
annoying.  Is there any way to "deactivate" this?

I use Gnome and XFCE.  Are there areas to tweak these window managers'
handling of Xinerama?  For example I would like to have the window that
allows to cycle through the open windows (Alt+Tab) be only shown on the
internal screen so I don't always have to look at both screens to see
where it is at now.  I'd also like to be able to move windows from the
external screen to the internal screen with a keyboard shortcut.
Anything like this possible?  I looked for a document of the type
"secrets to xinerama and everything you always wanted to know" but did
not find anything.

Regards

Rolf
