Public bug reported:

Binary package hint: xorg

Running on a Fujitsu Lifebook S6510, with a port replicator and an
external Acer LCD display.  Using 8.04.1 this was handled reasonably
well; when booted with the external display connected, the initial
resolution was 1280x1024, and when booted with only the laptop display,
initial resolution was 1280x800.  Using 8.10 Alpha-6, when booted with
the external display connected the initial resolution is 1024x768 (when
booting with only the laptop display the resolution is correct,
1280x800).

Examining the /var/log/Xorg.0.log file, I see that the server does in
fact properly detect the Acer display, and reads the available modes,
including 1280x1024.  However, in the log file on 8.10 there is a line
which reads:

/var/log/Xorg.0.log:(II) intel(0): Using fuzzy aspect match for initial
modes

When the external display is not connected, the corresponding line in
the log file reads:

/var/log/Xorg.0.log.old:(II) intel(0): Using exact sizes for initial
modes

There is no such line in the log file under 8.04.1.

Also, when I try to adjust the screen resolution there are no values
higher than 1024x768 listed.

Thanks.
