Description of problem: On my Dell Inspiron 6000, which has a built-in 1920x1200 display, if I plug in an external LCD panel that only supports up to 1280x1024 the radeon driver does not properly eliminate the 1920x1200 resolution from the mode list, thus making the external monitor unusable until I hand-edit the xorg.conf file. This makes it difficult to switch from using an external monitor at work and the built-in display at home. It appears the radeon driver is still using the specs for the internal display even when set to use the external display. Version-Release number of selected component (if applicable): xorg-x11-drv-ati-6.5.7.3-3.2 How reproducible: 100% consistant Steps to Reproduce: 1. Plug in external monitor 2. Set notebook to external display during boot (Fn + F8 for me) Actual results: X attempts to drive the external panel at 1920x1200 Expected results: The 1920x1200 resolution should be eliminated as its out of the monitor's spec and X should drop down to the next one in the list, 1280x1024. Additional info: This is also broken in FC4, but was working great when I first installed FC5t2. However in the past two weeks or so one of the Xorg updates broke it again.

Xorg.log file when booting on external display
I had quite a similar problem. I have an ATI X800 XL with DVI and VGA ourput and an LCD monitor Viewsonic VG191 1280x1024. When I connected it only via the DVI cable the monitor was not recognized (it was considered a CRT, gave a synch out of range and the resolution dropped to 800x600), while if I connected only **or also** the VGA, then the resolution was correctly set to 1280x1024. After several tries (forcing panel size, etc, etc) I found that the problem went away by using Option "MergedFB" "false" since I noticed that when the VGA cable was connected the MergedFB was executed instead of the monitor recognition (when VGA-cable is pluged). I was going to fill a bug for the system-config-display, but I found your bug report that looks quite similar. Let me know if my solution works. Here what I use xorg-x11-drv-ati-6.5.7.3-3.2 system-config-display-1.0.36-1 Please let me know if I have to fill a new bug report These bugs are being closed since a large number of updates have been released after the FC5 test1 and test2 releases. Kindly update your system by running yum update as root user or try out the third and final test version of FC5 being released in a short while and verify if the bugs are still present on the system .Reopen or file new bug reports as appropriate after confirming the presence of this issue. Thanks Installed FC5t3 today, still happening. Well, same here. Obviously since my system was up-to-date with rawhide. Again, is it the same bug (i.e. does the solution I suggest fix the problem) or should I fill a different bug report? Please file a bug report in X.Org bugzilla at http://bugs.freedesktop.org in the "xorg" component. Be sure to attach your current X server log, config file and all details directly to the X.Org bugzilla so that the upstream driver maintainers have as many details as possible in order to diagnose the issue. Once you've filed your bug report to X.Org, if you paste the new bug URL here, Red Hat will continue to track the issue in the centralized X.Org bug tracker, and will review any bug fixes that become available for consideration in future updates. Setting status to "NEEDINFO_REPORTER" and awaiting upstream bug report URL. > Please file a bug report in X.Org bugzilla at http://bugs.freedesktop.org > > Once you've filed your bug report to X.Org, if you paste the new > bug URL here Here it is mine https://bugs.freedesktop.org/show_bug.cgi?id=5991 Thanks guys, tracking upstream now... |
