What kind of graphics chip is that?

Are you sure you are using the radeonhd driver from the xorg-x11-drv-radeonhd package? (As opposed to the radeon driver from the xorg-x11-drv-ati package)

What package versions of kernel, Xorg driver are you running?

Any log files?

Is the issue reproducible by running "Xorg :2" from a root console login shell?

Can the issue be worked around by booting the kernel with the "nomodeset" parameter? Note that the radeonhd driver only works with nomodeset.

This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.

I'd like to ask you to reproduce the issue with current package versions and answer the questions from comment #1.

If we do not get any more information, we cannot solve this bug and have to close it INSUFFICIENT_DATA.

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.

[This is a bulk message for all open Fedora Rawhide Xorg-related bugs. I'm adding myself to the CC list for each bug, so I'll see any comments you make after this and do my best to make sure every issue gets proper attention.]
