hi,
the dual desktop solution was not the best for xfce, because it has
problems to safe the configuration of the panel for the both screens.
My System: IBM T40 2373-8cg with a radeon 7500 32MB(not shared).
My build in LCD resolution: 1024x768
My external TFT resolution: 1280x1024
What I try to achieve:
I want to use my nice new TFT with the resolution 1280x1024 and only the
external TFT, doesn't matter what resolution is on the LCD of the
laptop, because it is closed.
I can restart xorg for this, I need only the same desktop only on LCD of
the laptop. After a restart of the xorg and choosing an other config the
same desktop only on the external TFT, not more.
This solution is similar to the solution of windows. If you plugin your
external TFT and close your notebook, windows recognizes, that there is
an externel display and switches to this with the proper (higher)
resolution. If you open your notebook windows switches back to the lower
resolution on the LCD and the external TFT is switched off.
I need no Xinerama or clone mode, the only thing I want is to use the
external TFT at it's highest resolution without the laptop LCD.
And a possibility to use the internal LCD on the lower resolution on the
travel.
Thx for your help
Konstantin
