------- Additional Comments From dave at xdroop.com  2004-12-08 11:32 -------
I have this new Dell D600 laptop which I have installed FC2 on. It has a SXVGA+
(ie, 1400x1050) display. X will display at this resolution (at 24-bit depth) on
the LCD display, no problem. However, when I plug the laptop into a docking
station which has an Acer 77e 17" monitor attached to it, the Acer displays the
1400x1050 desktop, as viewed through a panning 640x480 window.

Experimentation has shown that the presence or absence of the dock (ie just
plugging the Acer straight into the back of the Dell) makes no difference.

I know it is possible to have this monitor display 1400x1050x24 -- Windows does
it. I've also driven this monitor at 1600x1280x24 when attached to a different
linux system. I also know that it is possible to have this Linux display
properly at this resolution on an external monitor -- I have a Sony G400 at the
office which does it.

I have gone through the FC2 System Settings -> Display applet and have
explicitly defined my monitor as an AcerView 77e. I have confirmed in my
/etc/X11/xorg.conf that there is an appropriate monitor defined:

Section "Monitor"
        Identifier   "Monitor0"
        VendorName   "Monitor Vendor"
        ModelName    "Acer 77e"
        HorizSync    30.0 - 72.0
        VertRefresh  50.0 - 120.0
EndSection

The presence and/or absence of this section doesn't appear to change anything.

When I boot the laptop at the office, it is connected to the Sony G400 and it
does the appropriate thing. At home, it still does not behave with the Acer.

In the Xorg.0.log, I've noticed that when connected to the Sony, the log reports:

(II) RADEON(0): Displays Detected: Monitor1--Type 2, Monitor2--Type 1

(II) RADEON(0): Monitor2 EDID data --------------------------- (II) RADEON(0):
Manufacturer: SNY Model: 290 Serial#: 8011257 (II) RADEON(0): Year: 2000 Week:
25 (II) RADEON(0): EDID Version: 1.2 [...lots of monitor stuff trimmed...] (II)
RADEON(0): End of Monitor2 EDID data -------------------- (II) RADEON(0): (II)
RADEON(0): Primary Display == Type 2 (II) RADEON(0): Clone Display == Type 1

...which tells me that it is detecting the Sony all by itself and making
appropriate assumptions. Where as when it is connected ot the Acer, I see:

(II) RADEON(0): Displays Detected: Monitor1--Type 2, Monitor2--Type 1

(II) RADEON(0): (II) RADEON(0): Primary Display == Type 2 (II) RADEON(0): Clone
Display == Type 1

...which tells me that either the Acer isn't detected at all, or it is detected
improperly. However, I still don't know what to do about it. I'm starting to
suspect that the config file is merely there for my amusement and xorg is trying
to auto-detect things at startup rather than read the config file.

What I can't find is an explanation as to why I'm getting this 640x480 on an
external monitor which is clearly capable of displaying much more, nor an
explanation of how to fix it. All pages on the web I've found suggest that it
means that my monitor can't run the video mode I selected (known to be false) or
that my video card can't run the video mode I selected (also known to be false).
It has to be a configuration problem.

Incidentally, a co-worker has the same problem, only he's started with FC2 and
done an "upgrade" install to FC3.
