Hi, I attach rhd_conntest output on an Asus A6Je Laptop with an X1450 Mobile graphic chip. I made it on a Debian 4.0 Etch x86_64 system. Without external monitor, and with a vga monitor connected. The laptop has dvi and s-video output, too. But I do not have such monitor. I hope these informations will be useful.
