If you get a console on the 3450 and X on the 7000, then both cards are initialized properly, so appears to be a X configuration issue. A few things to try: 1. try removing the Modes and Viewport lines from your screen sections. 2. try disabling acceleration: Option "NoAccel" "true" in the device sections of your xorg.conf 3. try disabling xinerama in your xorg.conf and start X with just two device and screen sections; one for each card with busids and remove the ZaphodHeads options. You should get two X screens. Something like: Section "ServerLayout" Identifier "Two cards" Screen 0 "Screen0" 0 0 Screen 1 "Screen1" RightOf "Screen0" EndSection Section "Device" Identifier "Card0" Driver "radeon" BusID "PCI:5:0:0" EndSection Section "Device" Identifier "Card1" Driver "radeon" BusID "PCI:1:0:0" EndSection Section "Screen" Identifier "Screen0" Device "Card0" SubSection "Display" Depth 24 EndSubSection EndSection Section "Screen" Identifier "Screen1" Device "Card1" SubSection "Display" Depth 24 EndSubSection EndSection -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
