This was done by design decision by the upstream X.org project.  You can follow the directions here to get ctrl-alt-backspace behavior back if you really want it.

Brian, just checking to see if is this actually for the xdm login screen or gdm login screen or if this is while you're logged into your desktop?

The default should be setup to have C-A-BS working at the login screen (at least for gdm).  If this isn't working, then something is broken.

If it's while you're logged into your desktop, there's actually a preference to enable/disable C-A-BS (default is disabled).  You can find the option in System->Preferences->Keyboard under the Layouts tab, click the "Layout Options..." button to open up the Keyboard Layout Options dialog.  There you can find the "Key sequence to kill the X server" checkbox option.

Changing the xorg.conf file that Warren mentioned in comment #1 works for both while your logged into your desktop and at the gdm/xdm prompt.

Since this bugzilla report was filed, there have been several major updates in various components of the Xorg system, which may have resolved this issue. Users who have experienced this problem are encouraged to upgrade their system to the latest version of their packages. For packages from updates-testing repository you can use command

yum upgrade --enablerepo='*-updates-testing'

Alternatively, you can also try to test whether this bug is reproducible with the upcoming Fedora 12 distribution by downloading LiveMedia of F12 Beta available at http://alt.fedoraproject.org/pub/alt/nightly-composes/ . By using that you get all the latest packages without need to install anything on your computer. For more information on using LiveMedia take a look at https://fedoraproject.org/wiki/FedoraLiveCD .

Please, if you experience this problem on the up-to-date system, let us now in the comment for this bug, or whether the upgraded system works for you.

If you won't be able to reply in one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you.
