I have an old MBA which has a broken screen so is useless as a laptop. I've been using it as a home server and have had it running in a spare bedroom hooked up to an external monitor for a while with no problems. I've since relocated it to the cupboard under the stairs as we had guest staying and didn't want it disturbing them. Also in the long term I like having it out of the way under the stairs. My issue is since moving it to under the stairs the 24 inch monitor I had it hooked up too can't go with it. I didn't see this as a problem as I've got auto login set up and planned to just use screen sharing/VNC to jump on it if I need to do any admin tasks. The trouble is I've noticed if I don't have the display connected I can't use screen sharing or VNC. I've also noticed if I have the display disconnected when I boot up I think the auto log on is failing as I can ping it on the network but none of the services come up. Has anyone seen an issue like this before and know of any workarounds (short of buying a small screen and connecting it!). I've also tried connecting the display, booting up and using screen sharing which is fine, but them if I disconnect the screen I can't VNC onto it again without first connecting the display.
