+++ This bug was initially created as a clone of Bug #150269 +++ From Bugzilla Helper: User-Agent: Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en) AppleWebKit/125.5.6 (KHTML, like Gecko) Safari/125.12 Description of problem: Basically I am using an Apple 17" LCD display with a Radeon 9000 on an older dual proc P3 box. The Radeon 9000 is detected, but the monitor type is set as "unknown", and as soon as it attempts to start X, it shuts down the DVI output from the card and lights the analog one. I tested it by connecting an analog display after it kills the DVI display and it is sending signal to the analog vga output of the card after that. This is a real problem if, like me, you have a DVI-only monitor. I had to hook up the VGA input from my rear projector to confirm this problem, and then had to do the install from the ascii installer. Version-Release number of selected component (if applicable): NOTE: I cannot attach X config or logs because the machine is unusable for me when it does this, however, the x-config is whatever anaconda chooses during graphical installer boot for the radeon 9000 video card and the "Unknown" monitor type. How reproducible: Always Steps to Reproduce: 1. Connect a DVI-only flat panel of a type unknown to FC3 to a Radeon 9000. 2. Boot from install CD, select graphical installation 3. On start of X, DVI panel will lose sync and analog VGA output on card will light. Expected Results: There should at least be an installer switch allowing this to be overridden. It should be smart enough to detect that the unknown monitor it probed is connected to the DVI output of the card. If it drove the DVI port at 640x480 it would at least be possible to complete the graphical install. This problem continues after installation, as Fedora boots into the GUI login screen and against de -syncs the DVI port in favor of the analog VGA port. It should have a configuration profile for detecting Apple displays. Additional info: Note that I am using an Apple display that has the proprietary ADC connector on it, so I am using a separate device to do power injection through ADC. ADC is just DVI with extra pins for power and USB, so all the device does is inject the necessary power and give you a USB and DVI cable on the ends. No signal processing occurs in the device, and Windows XP sees the display as a plain jane 17" digital flat panel.

We do not have this hardware available to attempt to reproduce this problem. My suggestion for best results, is to report it directly to X.Org, which will greatly increase the likelyhood of someone being able to attempt to reproduce the issue and provide a fix sooner. You can file an X.Org bug report by visiting: http://bugs.freedesktop.org Once you have filed your bug report in X.org bugzilla, please paste the URL here and we will track this issue in the X.Org bugzilla, and review any fixes that become available for consideration in future Fedora Core updates.
Setting status to "NEEDINFO", awaiting upstream bug URL for tracking.
Hopefully I submitted for thw right component. Here is the link to the x.org bugzilla entry. https://bugs.freedesktop.org/show_bug.cgi?id=2985
Bug submitted to upstream bug tracker in comment 4 was against inappropriate upstream product.
Thanks for reporting upstream Justin. I corrected the upstream component to "xorg" and reopened the bug, along with a request to supply the complete details in the upstream report for X.Org developers. We'll track the issue in the upstream bugzilla now. Thanks again.
