No way of testing it at all myself though.
I use the dpms feature of sys-apps/vbetool to control the state of the display from a shell script called by acpid. It works even when X is not running and does not need access to the X display if X is running. Also, it works with graphics cards from multiple vendors, as it uses VESA extensions. From personal experience, I know it works with the Intel graphics chipset in my laptop (x86) and also with the Nvidia graphics card in my desktop (amd64). The latter does not have a lid to close, of course, but vbetool can still turn off the display. --Brandon Vargo
