xorg.conf for IBM Thinkpad T42 laptop with DUAL HEAD and OpenGL
I spend some time to configure my T42 laptop to used dual head together with OpenGL. I used MergedFB with MergedNonRectangular. Google Earth works ;-) xine only on the LCD-screen... Here is the result. If you have any questions or ideas for improvements, do not hesitate to contact me at
http://www.abmh.de/msg.html. The config-file and a log-file of the X-start-up sequence is included in the zip-package. I also tried a wide screen (1600x900) but I don't get it working.
