:-) well I am not know to be lucky hard/softwarewise ... As promised I checked all the stuff today on an external DFP... and no it does not work... the DFP got detected but was not displaying anything... But when I used Option "MonitorLayout" "TMDS" then it displayed the 1280x854 (although it should have been 1280x1024 -> ugly stretching on the DFP). forcing 1280x1024 makes it work, but the internal DFP flicker (and I got scared of destroying something). > > > Yes, the driver probes for an external display via DDC and disables > > > output if it doesn't detect one.

But the resolution got limited as I was using DDC... so I really had 1280x854 as the true resolution on a 1280x1024 desktop... > > I am still looking for 'the' solution, where one uses the internal DFP > > most of the time then connects an external CRT/DFP and makes use of that > > one without having to restart X... > > > > I thought I could do this by using a multihead config with two displays > > :0.0 and :0.1 but there I had the problem that the mouse cursor was > > somehow only on :0.1 and I did not know how to set the mouse to be on > > :0.0 ... > > The mouse pointer should work the same way as with Xinerama, but moving > windows between the heads probably requires special support as found > e.g. in GTK as of 2.2. Well, I really tried it out. I started gnome2 and had the panel and background image on both screens. Nautilus/appletts etc were only on :0.0 ... opening a window on :0.1 and starting a window manager there made me feel quite comfortable with using the second head. However I first have the mouse on :0.0 when I move it too far right/down it is gone and now on :0.1 ... but there I had no chance to move it back to :0.0 :-/ I would prefer to set the mouse button to :0.0 or :0.1 manually by using some program... but don't know any of those... > > A different option would be to use a xinerama mode, and have a program > > to somehow en/disable the mouse going to the external display... > > Unfortunately, I don't know of a way to achieve this, but again I > suspect that the mouse would be less of a problem than windows. well true, but I can for now live with certain windows beeing only on :0.1 and some on :0 > > Very good job Michael ! > > But I only do my small part... thank all the people working hard on > XFree86, in particular Hui Yu for his great radeon driver work.

The combination of http://bugs.xfree86.org/show_bug.cgi?id=276 and > xrandr might be interesting. Indeed that could already be the first really usable workaround (comment #49) until pseudorama (comment #51 above) is fully supported... I don't know the randr extensions, but are these already supported, if so then it is really worth trying out the above patches. Soeren.
