Hi Tomas: Try to set the "virdual screen" in duble size orizontal. In others words, if your screen mode is set to 800x600, set the virtual to 1600x600. That has worked for me, using 2 nvidia. Later I have buyed a dual card. :) same problem, but, changing the virtual has solved the problem. :) ----- Original Message ----- From: "Tamas Hauer" <tamas.hauer@xxxxxxxxx> To: <xfree86@xxxxxxxxxxx> Sent: Tuesday, August 24, 2004 6:02 AM Subject: Dual Screen not working, help? > Hi all, > > I am trying to start an X server with two screens on two VGA cards. > Here they are: > -------------------------------------------------------------------------- -------------------------------------------------- > [root@pcettmg01 root]# lspci | grep VGA > 01:00.0 VGA compatible controller: ATI Technologies Inc Rage 128 Pro Ultra TF > 02:01.0 VGA compatible controller: ATI Technologies Inc 264VT [Mach64 > VT] (rev 40) > (see the output of lspci -vv at : http://cern.ch/tamas.hauer/X/lspci) > -------------------------------------------------------------------------- -------------------------------------------------- > > The interesing ( I think) part of XF86Config is below, (the whole > thing is at: http://cern.ch/tamas.hauer/X/XF86Config.dual).
