Description of problem:
When starting X or running system-config-display, I get a black screen with a message from my
monitor stating that an attempt is being made to run it at an unusable refresh rate.
The video card is a Matrox G450 low-profile. This card has a DVI connector on the bracket and
includes a special adapter cable that splits the DVI connection into two VGA connectors. The monitor,
an NEC 2470WNX, is attached to one of the VGA connectors.
Version-Release number of selected component (if applicable):
I've tried moving xorg.conf out of the way; that didn't change anything.
If I run system-config-display with "--set-vsync=60 --forceui", I do
successfully get the UI. However, it seems system-config-display doesn't put
anything in xorg.conf to reflect the vsync=60 setting. As a result, X still
isn't usable when it runs.
If I plug the monitor directly into the DVI port, system-config-display will run successfully without any
arguments. However, it comes up at 800x600 and reports the monitor as unknown; 800x600 and
640x480 are the only available pixel dimensions.
In spite of this, X still tries to run the monitor at an unusable refresh rate and I get the same black screen
with the error message from the monitor.
Thanks for the bug report. We have reviewed the information you have provided
above, and there is some additional information we require that will be helpful
in our diagnosis of this issue.
Please attach your X server config file (/etc/X11/xorg.conf) and X server log
file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file
attachments using the bugzilla file attachment link below.
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.

Log from session with the monitor connected directly to the DVI port
conf & log attached.
I have also observed similar behavior when connecting the card to an NEC
MultiSync FP950, an analog CRT monitor.
Behavior when running with no xorg.conf is already described above.
Pardon my naivete, but why do you think this has something to do with the mouse driver?
Setting component to xorg-x11-drv-mga; assuming setting to xorg-x11-drv-mouse
was an error.
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:
Still a problem in Fedora 11.
