How reproducible:

Everytime.


Steps to Reproduce:

Work arounds:

A. (Using DVI) Change to a lower resolution like 1680x1050.
B. Use the VGA connector instead.

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 add drm.debug=0x04 to the kernel command line, restart computer, and attach

* your X server config file (/etc/X11/xorg.conf, if available),
* output of the dmesg command, and
* system log (/var/log/messages)

to the bug report as individual uncompressed file attachments using the bugzilla file attachment link above.

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

Thanks in advance.

Judging by the symptoms, I have the same problem. (Just upgraded to F14 from F13, using preupgrade.)
