Hi all, <br><br>Below is my xorg.conf file. I just set a Ubuntu box to work with two monitors using MergedFB so that we can obtain 3D acceleration on both monitors. In a Dell tower with an ATI Radeon 9200 Pro. The result I got is that the Gem window only renders on the first screen, and not at all on the second. Do you guys know a turnaround so that I can get hardware acceleration on both heads ? Thanks again.
