first off there are a few errors in your config: remove these lines: Option "CloneMode" "1280x1024" Option "CloneHSync" "28-92" Option "CloneVRefresh" "48-85" Next this line is wrong: Option "MonitorLayout" "LVDS, TMDS" TMDS is for DVI ports. you want something like this: Option "MonitorLayout" "LVDS, CRT" You can also try it without that line all together. Also you might try adding this to you config (both screen sections) if you want to use DDC modelines: Option "DDCMode" "true" and finally, in your serverlayout you need something like this: Section "ServerLayout" Identifier "Default Layout" Screen 0 "Laptop LCD" Screen 1 "Sony SDM-P232W/B" RightOf "Laptop LCD" InputDevice "Mouse0" "CorePointer" InputDevice "Keyboard0" "CoreKeyboard" InputDevice "DevInputMice" "AlwaysCore" EndSection Change the relationship as you see fit: LeftOf, Above, or use absolute coordinates. see the XF86Config man page for more. Since you are using such an old version of 4.3, you will also need to add option "HWcursor" "false" to your device configs otherwise your second head will turn off when you move the mouse onto it. this bug was fixed in cvs. Also right now the DRI does not work in xinerama mode. if you want 3D with dualhead you will need to use Mergedfb available in DRI cvs. http://bugs.xfree86.org/show_bug.cgi?id=276 Alex -------------------------------------------- Hi, Sorry to bother you with a config question when I'd rather you guys spent your time building more great code ... That said, I've been working this problem for almost 4 days straight now and my boss is starting to notice the down time ... Basically I have a TP T40 with a 1400x1050 native display controlled by an ATI Radeon M9 chip. The M9 is a dualheaded beast and I want to run my new Sony SDM-P232W/B monitor from the external analog video out port. I'm running Red Hat and XFree86 versions as follows: ******************************************************************************* XFree86 Version 4.3.0 (Red Hat Linux release: 4.3.0-2) Release Date: 27 February 2003 X Protocol Version 11, Revision 0, Release 6.6 Build Operating System: Linux 2.4.20-3bigmem i686 [ELF] Build Date: 27 February 2003 Build Host: porky.devel.redhat.com Before reporting problems, check http://www.XFree86.Org/ to make sure that you have the latest version.

I have read several sites listing differing sets of opitons for the "radeon" driver and played with them for a good while. I've seen several forum postings offering assistance and "working config files" posted by folks with similar undertakings and tried to copy their work without success. I tried adding a second screen to my config file and ended up with what appeared to be a second instance of X running for the external monitor (with same weird resolution issue as below). Not what I wanted. I want to use the external monitor instead of the built in one, not in addition to it. What I can do: 1. Laptop display works fine. 2. Laptop display working AND external monitor working, but with the wrong resolution. This is rather difficult to properly explain. One representative misconfiguration achieved by removing the "CloneMode" line from the attached XF86Config file is that the VGA adaptor spits out 1400x1050 just like the internal CRTC but the monitor syncs to 1280x1024 so I loose 26 lines off my screen. As configured in the attached config file I get the external display sync'ing at 1280x1024 and a virtual 1400x1050 display that I can pan around on. When I set the "CloneMode" to "1600x1200" my monitor wont sync to it ... complaining that it doesnot support 215.2KHz / 175Hz or some such random combination of numbers. From this I assume that the M9 is sending garbage to the external port. What I want to do: I want the internal display to run at 1400x1050 (or optionally be off) and the external display to run at 1920x1200 as a clone of the internal display. I'm sure this is doable, if only I can figure out the right config file for the purpose. Any thoughts appreciated. Thanks, Tc. (See attached file: XF86Config) Tony Cowan - IBM SWG Services.

Don't wait too long to figure that out. __________________________________ Do you Yahoo!?
