Thanks for the bug report and sorry for late reply to your report.
Please attach your X server config file (/etc/X11/xorg.conf) to the bug report
as individual uncompressed file attachment using the bugzilla file attachment
Could you please also try to run without any /etc/X11/xorg.conf whatsoever and
let X11 autodetect your display and video card? Attach to this bug
/var/log/Xorg.0.log from this attempt as well, please.
We will review this issue again once you've had a chance to attach this information.
Thanks in advance.
Here are some findings from my system:
I'm running FC6 on a DELL D620 laptop. After installing the
915resolution tool I also got X11 running in the native 1440x900
resolution using the integrated Intel graphics card and the "i810"
driver. Now when I put the laptop into the docking station I can't get
any X11 output neither to the external displays attached to the
docking stations DVI and VGA port nor on the internal laptop display.
Text mode output to the external displays seems to work, i.e. when the
laptop lid is closed I get the console output on the display attached
to the DVI port.
I also tried the new "intel" driver, but with this one I can't even
get X11 output to the internal display when the laptop is undocked.
I'll attach the logs you requested.

As of xorg-x11-drv-i810-1.6.5-19.fc7, 915GM and all 945 and 965 chips will use
the intel modesetting driver by default. Please update, and test with that
driver, and reopen if you have further issues.
