I was going to suggest that you plug it into the hotplug_stage_two function but it looks like you have already done that. Things might be routed differently now then since the last time I looked at the code, are you sure that stage_two is being run? > Any thoughts on the interface?

On the whole I think exporting properties are fine, but I don't think setting modes and crtc's are to be done in sysfs. However it is entirely possible. > Thanks, > Jesse Cheers Jakob. ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
