Description Alessandro Polverini 2004-12-01 17:50:14 UTC
Description of problem: I've a radeon 9600 with two flat panels, one on the DVI output and the other one attached on the analog output. During install they both have the same image, but the screen on the DVI output is not readable because the screen behaves like it has been set a bad frequency (i.e.: the image rolls very fast and is distorted). I was able to install just because I had also the analog flat panel. Version-Release number of selected component (if applicable): Don't know how to get this one: is the installer of FC3. Relevant lines from lspci [-n]: 01:00.0 VGA compatible controller: ATI Technologies Inc RV350 AQ [Radeon 9600] 01:00.1 Display controller: ATI Technologies Inc RV350 AQ [Radeon 9600] (Secondary) 01:00.0 Class 0300: 1002:4151 01:00.1 Class 0380: 1002:4171 How reproducible: Always. Steps to Reproduce: 1. Get a radeon 9600 2. Put two flat panels, one on the analog output, and the other one on the DVI output 3. boot from the install CD

Do a forced text mode installation, and after installing, configure the system to boot up into runlevel 3. Update your entire system with the latest Fedora Core 3 updates, and reboot into the latest kernel. After you've updated your system, run: system-config-display --reconfig Now try switching to runlevel 5 by doing "init 5". If the problem still persists, reboot again, and upgrade to the xorg-x11 in Fedora development (rawhide), which is currently 126.96.36.1993 (6.8.2rc3) slated for release in a few weeks. We will be releasing 6.8.2 as an official FC3 update shortly, so it is important to test this new version. If the problem still exists with rawhide xorg-x11, please update the bug report with status updates. Also, please attach your X server log file, config file, and /var/log/messages as individual uncompressed file attachments. We also recommend filing a bug report in X.Org bugzilla at http://bugs.freedesktop.org in the "xorg" component to maximize the likelyhood of someone finding a solution should the problem still persist. Thanks in advance.

Setting status to "NEEDINFO", awaiting upstream bug report URL, and the results of testing xorg-x11 from rawhide.
Comment 3 Alessandro Polverini 2005-02-01 09:33:38 UTC
Sorry but I do not understand exactly why I need to do that test: my system works just fine with both flat panels, the problems I have are switching to text mode (#141500), and flickering of the DVI monitor *during* the install (this bug). After the install, X works fine with both monitors.
Comment 4 Mike A. Harris 2005-03-22 15:23:39 UTC
We need additional information in order to troubleshoot the problem, including getting you to test some things and provide us with the feedback of your testing. If X works fine on both monitors after installation, that is rather confusing because it is the exact same X server and video driver being used in the installer, and after install. The only thing I can think of which might be different is wether your flat panel gets detected correctly by the hardware probing code outside of the X server (ddcprobe). In any case, if we were to isolate the problem and fix it, you'd have to install an update to get the fix, it wont be on the CD image, so there is probably no way to solve this problem if it only occurs on the initial FC3 installation only. We have released an update into FC3-testing of xorg-x11-6.8.2. Please upgrade to this new release, and if the problem persists with 6.8.2 in FC4-test1 or later OS releases or test releases, please reopen this report and provide details.
