Here are some conntest results for an Acer Aspire 5112WLMi laptop with a Mobility Radeon X1600 video card. It has a 1280x800 panel, and separate VGA and DVI outputs. Note that I didn't do any futzing with the fglrx driver to try and actually *display* anything on the external monitors; I presume from the description of conntest that this is more or less irrelevant to the operation of conntest. With no external connectors (just the panel): Checking connectors on 0x71C5, 0x1025, 0x009F (@01:00:00): Load Detection: RHD_OUTPUT_NONE HotPlug: RHD_HPD_NONE DDC: RHD_DDC_NONE LVDS Info: 18bits, single link, LDI Panel found.

Power Timing: 0xF9F, 0x000, 0x03, 0x19, 0x1F4 Macro: 0x0C720407, Clock Pattern: 0x0063 [1] I suspect that using a VGA-DVI cable is the same as using a VGA cable with a VGA-DVI adapter. I didn't have an adapter to hand to test this theory, though. -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org
