From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20030225 Description of problem: I performed an update of my Red Hat Linux 9 system (using apt against freshrpms.net's redhat os and updates repositories). After the update finished, I restarted my machine, and at that point the X Radeon driver would no longer detect the second display. This results in both my monitors displaying the same thing. I miss my Xinerama (*sniff*). The XFree86.0.log file at the above URL has the exact message at line 667: (WW) RADEON(1): Only one monitor detected, Second screen will NOT be created Additionally, I have placed my XF86Config file at the above URL. This configuration was working perfectly before the update. The graphics card in question is an ATI Radeon VE (Dell Precision 350n) with dual-display support, configured for dual VGA outputs. Version-Release number of selected component (if applicable): XFree86-4.3.0-2.90.43 How reproducible: Always Steps to Reproduce: 1. Configure X for dual-head Xinerama support 2. Start X 3. Watch X ignore the second head and start in single-head mode Actual Results: X started in single-head mode. Expected Results: X should have started in dual-head mode with Xinerama support.
