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
Version-Release number of selected component (if applicable):
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
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.
