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),
* X server log file (/var/log/Xorg.*.log)
* 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.

Dear Matej Cepl:

I will be sending the information you requested at 2011-05-27 11:34:46 EDT by tuesday May 31 2011.


Also, i want to update my bug description.  I noticed that only the highest resolution that my machine supports is available.  The highest resolution for my machine is:  1600x900 16:9

Thus, all the other modes with 16:9 are not being detected.   I know this because i installed windows 7 64BIT along with the video driver; and all these modes below were available! Therefore, the modes that are not detected with Fedora 15 at 16:9 are the following:

1440x900  16:9
1366x768  16:9
1360x768  16:9
1280x800  16:9
1280x768  16:9
1280x720  16:9
1024x768  16:9
960x600   16:9
800x600   16:9

In Fedora 15, only 1600x900 shows up with 16:9 mode. The other three modes below are using 4:3

1024x768        
800x600          
640x480

Comment 8 Fedora End Of Life 2012-08-07 14:42:08 UTC
This message is a notice that Fedora 15 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 15. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. At this time, all open bugs with a Fedora 'version'
of '15' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that
we were unable to fix it before Fedora 15 reached end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged to click on
"Clone This Bug" (top right of this page) and open it against that
version of Fedora.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

The process we are following is described here:
