+++ This bug was initially created as a clone of Bug #551920 +++ Created attachment 381346 [details] xorg.conf file Description of problem: On an HP nc2400 with an Intel 945GM video card that previously was running Centos 5.3 with no video problems. On install of FC12, video was set to 800x600. I installed system-config-display and went to hardware, configuring the monitor of LCD panel 1280x1024, and then seelcted 1024x768 resolution for the setting. I logged out and logged in to reload X, and the video was indeed now at 1024x768. I then pressed the function combination to switch to the external monitor (which is connected via a Belkin KVM), and it comes up only in 800x600 resolution. when I am at the 'both' displays option, then both the internal and external are 800x600. I cannot get the external at 1024x768 as I previously had with Centos. Version-Release number of selected component (if applicable): Whatever is current with FC12. How reproducible: Freddog_de.uk reports a similar problem on the Fedora COmmunity mailing list on a Toshiba.

If you won't reply in one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you. -- --- Additional comment from hoffmann.fr on 2010-09-28 06:35:30 EDT --- Created attachment 450142 [details] dmesg output Created attachment 450143 [details] Xorg.log output I would like to reopen this bug, as I am observing _exactly_ the same behaviour on DELL Latitude D520 hardware. This worked on Fedora 9. And the same installation under WinXP also allows the higher resolutions to display on the external VGA channel. Please find the requested files attached. --- Additional comment from mcepl on 2010-09-29 16:00:31 EDT --- (In reply to comment #5) > I would like to reopen this bug, as I am observing _exactly_ the same behaviour > on DELL Latitude D520 hardware. > > This worked on Fedora 9.

I am sorry, but it would be really much more pleasant for us if you open the new bug for this rather than reopening this one. [... deleted discussion about how to reopen this bug ...] Done!
This message is a reminder that Fedora 12 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 12. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '12'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 12's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 12 is 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 please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. 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: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
I understand that you have to do some housekeeping. But let me remind you that these symptoms had originally be reported as bug 551920 as a regression! It should get attention with high priority. *** This bug has been marked as a duplicate of bug 638123 ***
