Thanks for the one-liner above: works like a charm here, and out of
the box, with an about 9 years old VGA monitor, connected to an
alubook 5,8, and with an ATI driver from experimental that you

This is what it obviously does:
$ xrandr -q
Screen 0: minimum 320 x 200, current 1440 x 1024, maximum 1440 x 1200

All I did - after installing xserver-xorg-video-ati_6.7.196-1 - was
adding a single extra line to the xorg.conf that I attached to a
message earlier in this thread:

 diff -u xorg.conf xorg.conf.07.11.23

and restarting X.

As to 'xrandr -q' from above:
Ladies and Gentlemen, please note that the correct values of the
connected VGA (1280x1024, at 60 Hz, IINM) are correctly and automagically
detected, without xorg.conf knowing anything of them ...

It's a DDC 1/2B VGA, meaning, IINM, that this beast automatically
communicates its technical capabilities to its host system. And
outside it reads Compaq, but IIRC a Hyundai is actually inside ...

Oh yes: and
xrandr --output DVI-0 --off
switches the attached VGA off ... the alubook screen is shaking a bit
for ~ half a sec, but it works.

> is required explicitly in order to enable the external display.

I call it hotplugging anyway  ... :)


Since installing the new driver some artifacts are visible around the
mouse-pointer in its default "arrow" image ...  Please let me know if
a photo from that might help ... 

And the mouse is completely gone on the console .. haven't had time,
yet, to google/explore that ...

Oh yes, and this: about 3 from 10 Xserver restarts from the KDE/KDM
login screen fail here, with e.g. the login desktop image melting into
some unformed psychedelic colors - I remember having had this previous
times when booting the machine .. like then it can be "fixed" now by
simply putting the machine to sleep, and waking it again, as it seems

Now let's see now how I can connect my telly via the S-composite
connector to this computer ... :)

No sidenote:
All that is real fine progress, Michel.
So last, but most certainly not least thanks to everyone who made all
this possible, among them

 Rickard E. (Rik) Faith
 Kevin E. Martin       
 Alan Hourihane        
 Marc Aurele La France 
 Benjamin Herrenschmidt
 Michel Dänzer         
 Alex Deucher          
 Bogdan D.             
 Eric Anholt           

Please let me know if you need some testing for this driver, be it on
an older TiBook IV, or the alubook 5,8.

Now I need breakfast, at last ... :)
