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.
Whoops! Didn't find this request until now.
In the process of trying to install nVIDIA drivers from livna.org, this
installation crashed. It never recovered well, producing an unusable system
due to SELinux errors and issues. I found the best course was to wipe the
drive and install FC6.
Sorry about the long delay.
OK, so I assume that it means you are not able to help us with ATI drivers
(reopen , please, if I am wrong).
Consider this a re-open then. I am available to help in any way I can. I can
re-install FC5 on a spare drive. Once that is done, I will post the above
However, Would you rather have an FC5 or an FC6 install to play with first?
Either will take just about as long, so there is not much of a difference to me.
Fedora Core 5 is no longer supported, please, could you reproduce this bug with
the updated version of the currently supported distribution (Fedora Core 6, or
Fedora 7, or Rawhide)? If this issue turns out to still be reproducible, please
let us know in this bug report. If after a month's time we have not heard back
from you, we will have to close this bug as CANTFIX/INSUFFICIENT_DATA.
Setting status to NEEDINFO, and awaiting information from the reporter.
Thanks in advance.

Considering the question in comment 4 -- I guess comment 5 answer this. Please,
go ahead and try to reproduce this bug in FC6. If you will manage to do so,
please attach all the information required in comment 1.
Reporter, could you please reply to the previous question? If you won't reply in
one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you.
No information requested provided, no joy for anybody -- closing this bug as
INSUFFICIENT_DATA. Reporter, if you could, please, reopen with additional
