Have a brand new macbook pro 13" with SL, hooked up to a vga 1680*1050, and it can never be detected at boot, the screen goes blue several times and nothing. I have to manually unplug and replug the display adapter to get it to detect. "detect monitors" does nothing either. The cable goes through a kvm but it's the same without. Also it's not an apple brand adapter. I've been told it's a common problem with vga, and it's coming from the macbook. Do you have any workaround? It's pretty annoying.
