I can also confirm the behaviour on i386 exactly after the same update of Xorg.
Can please someone isolate this? Confirm it maybe?
Confirmed same on Intel 855GM - same Xorg version, i386 package. Seems the
problem is in the Xorg server.
Here is a backtrace in the log (intel 855GM, i386)

Fatal server error:

Also this happens only in gnome-session, if I telinit 3 and start X with Xorg &
and then open a terminal there I can switch the monitors.
Sometimes the first switch in gnome session works but then when I try to switch
back it crashes.
Please, would someone take a look at that, its been long time i cannot connect
my laptop to any monitor.
This is to confirm that the issue is resolved with
Sorry but I have to re-open this - the solution seem to be partial.
Now on the current release in fedora updates I can switch the monitors but only
one at a time on the command line i.e.
xrandr --output ... [other options]
If I use the --output parameter once more on the same command the X server
crashes again i.e.
xrandr --output VGA --mode 1280x1024 --output LVDS --off
this crash the X
This implies that the GUI in fedora designated to manipulate the screen is
unusable as it tries to use both --output parameters at the same time to turn
off the LVDS and on the VGA with the selected mode and this crashes the server.
I believe I'm seeing a similar problem. I have script which invokes xrandr, but
it invokes xrandr once per output. The crash is not consistent, but usually
occurs when changing the number of heads, e.g. 1 head --> 2 heads or 2 heads -->
1 head. Sorry, but I haven't figured out the exact pattern. Server is:
This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '9'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 9's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 9 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
