Subject: Troubles with Xinerama + radeon driver on Xorg
From: Alex
Date: 2007-07-17 23:56:42
Quick facts: - xorg.conf can be found here: http://cl1p.net/xorgconf/ - I have an ATI Radeon 9800 (AGP) with a DVI and VGA port. - "screen0" is an LCD monitor ("ibm") connected to a \ DVI-to-VGA adaptor ("dvi2vga") - "screen1" is a CRT monitor ("viewsonic") connected to a \ VGA port ("vga") I want to use Xinerama with these two monitors, but its behavior is a bit odd. With my current setup, the same image displays on both screens. However, the mouse pointer can move between them. Each screen displays the left half of a larger virtual screen. Even though both screens show the same image, only the left screen is interactive--programs lose focus when I move the mouse cursor to the right screen. I am using the ion3 window manager, but I do not think it is to blame for the screen cloning. A person using Fedora Core explains the same problem here: http://www.driverheaven.net/linux-radeo … 0-pro.html The solution offered there is to use an older version of the radeon driver. I might have to try that. -Alex

I use an IBM laptop with an external LCD as well... including using Ion3 and \ Xorg. I've attached my xorg.conf; I hope it may be useful. > I am using the ion3 window manager, but I do not think it is to blame > for the screen cloning.

I'm running a similar setup -- I sent msg earlier, but I think it didn't go through. In any event... find my xorg.conf at end of this msg. > I am using the ion3 window manager, but I do not think it is to blame > for the screen cloning.
