your version of xfree86 is way too old. please try with a newer version. there were quite a few bugs in the pre-4.3 version. you may need the "monitorlayout" option which wasn't added until after 4.3 was released. Also, as was poined out, you can also use mergedfb for dualhead. Alex ------------------ Hello, I have a portable (Sony GRX316MP) which contains a Radeon 7500 mobility which has dual-head capability. I know this chip CAN handle non-cloning dual head because the X server from Xig does it (and Windows of course). But the Xig server has some problems and it seems to only support two heads in Xinerama mode; I want to have separate X displays on both heads. But whatever configuration I try in XFree86 I at the most get a cloned screen, i.e. the secondary monitor shows (part of) the primary screen. The primary screen is the laptop's LCD at 1600x1200@75Hz, the secondary monitor is an LCD 1280x1024@75Hz. To get the secondary screen to work at all I had to specify Option "CloneMode" "1280x1024" in the device section for the primary head, else it used the mode for the primary head regardless of the information in the Screen section and the information returned by DDC from the 2nd screen. Parts of my XF86Config: Section "ServerLayout" Identifier "XFree86 Dual-Head" Screen 0 "Screen0" 0 0 Screen 1 "Screen1" RightOf "Screen0" InputDevice "Mouse0" "CorePointer" InputDevice "Keyboard0" "CoreKeyboard" Option "Clone" "off" EndSection Section "Device" Identifier "Card0" Driver "radeon" VendorName "ATI Technologies Inc" BoardName "Radeon VE" BusID "PCI:1:0:0" Option "CloneMode" "1280x1024" Option "CloneVRefresh" "75-75" Screen 0 EndSection Section "Device" Identifier "Card1" Driver "radeon" VendorName "ATI Technologies Inc" BoardName "Radeon VE" BusID "PCI:1:0:0" Screen 1 EndSection I also have Screen, Monitor and Modes sections for each separate monitor. Whatever I do I either have no display on the secondary monitor at all, or the server dies with a SEGV, or I have a cloned display instead of a dual head (separate X desktops). I tried the Xinerama stuff also but this has no effect whatshowever which seems logical since i do not HAVE two heads to Xinerama on ;-) I tried this on the SUSE 9.0 stock XFree which seems to be a patched prerelease of XFree 4.3 (it has the warnings and reports a 4.2.99 version number). But I also compiled XFree 4.4-with-patches from source and it doesn't work either. Can ANYONE help me? Please? I'm currently looking at the radeon_driver source but before I know what's going on there will take a while >-( Thans, Frits Jalvingh __________________________________ Do you Yahoo!? Yahoo!
