Expected results:


Additional info:
System-config-display is also installed and a xorg.conf file with indications for preferred resolution in section monitor is in place. (Auto detection of monitor resolutions is a problem because of KVM switch) 

driver: nouveau

It may be a conflict with s-c-d

Comment 1 Rex Dieter 2009-11-18 00:41:43 UTC
It's likely a display driver bug, where the xrandr probe crashes the X server.

What video hardware and driver are you using?

Comment 3 A. Mani 2009-11-18 02:52:48 UTC
The system was updated from rawhide to F12 (stable) (but that should not matter most probably).

Comment 4 Rex Dieter 2009-11-18 04:39:33 UTC
Looks like nouveau is the likely suspect then, re-assigning.

Comment 5 Matěj Cepl 2009-11-19 20:21:39 UTC
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, if available), output of the dmesg command, 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.

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.

Comment 10 Adam Williamson 2009-11-25 20:59:06 UTC
Please don't compress attachments that are plain text and reasonably short, it makes them far less convenient to work with. Can you please reproduce the issue and then attach /var/log/Xorg.0.log.old , which should be from the crashed session and hence contain the crash information? Thanks. Also, please do not set the priority field when reporting bugs. Per policy, it is reserved for the maintainers to use however they find most useful.

Comment 12 Ben Skeggs 2009-11-26 01:59:25 UTC
One thing I notice, why are you using ShadowFB?  Can you try removing that option and seeing how things work without it?

Comment 13 Fedora Update System 2009-11-26 03:40:21 UTC

Comment 14 A. Mani 2009-11-26 22:10:11 UTC
Problem is solved by commenting out ShadowFB line

Comment 15 Adam Williamson 2009-11-27 18:25:42 UTC
can you also test _with_ the ShadowFB line, and the updated package from comment #13? Thanks.

Comment 17 A. Mani 2009-11-28 01:21:02 UTC
With updated package and updates-testing enabled, and ShadowFB line, clicking on system-settings --> Display is OK, but changing resolution results in login screen.

I will attach the log
