From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20030225 Description of problem: I was running a dual head X on RedHat 7.3 with an ATI Radeon VE card with no problems. I upgraded to RedHat 9, but I saved the XF86Config-4 file from my 7.3 installation. Once I had 9 installed, I used the same XF86Config file (with Xinerama enabled), and X starts up fine, but when I move my mouse from one of the screens to the other, it shuts the first screen off. I can fix it by Ctrl-Alt-F1 and then Ctrl-Alt-F7, but that only lasts until I move the mouse over. This happens both with GNOME/Metacity, and with TWM (just by running xinit and then starting TWM by hand). Note that the window is still there, as I can drag windows onto it, and do everything else; it's just that the monitor is in sleep mode. I have not yet had a chance to test with another video card, but within the next few days I will try that. I have attached my XF86Config file for reference. Version-Release number of selected component (if applicable): XFree86-4.3.0-2 How reproducible: Always Steps to Reproduce: 1. Have a Radeon VE with Dual Monitors. 2. Use the attached XF86Config. 3. start a window manager, either with xinit and then TWM, or startx (starting GNOME). Actual Results: Both monitors come up fine (which results in a single 2048x768 display), but moving the mouse off of the "left" screen (in my setup) causes the "left" monitor to go blank. Expected Results: The "left" monitor should stay on, and continue to operate. Additional info:
Created attachment 91163 [details] XF86Config file that produces the bug. This is the XF86Config file that I am currently using.
