I have an external monitor for my mac book pro that I would use as my primary monitor when sitting at my desk. To use it I would simple plug the DVI cable into the side, wait for the external to display, shut the laptop lid which would put the laptop to sleep, re-awaken the lap top by moving an external mouse, and then the external monitor would display nicely at the proper resolution of ~1680x1050. I would then usually re-open my laptop monitor to allow better venting, but this was not necessary to making things work. For some reason this morning I am no longer able to get the above steps to work. Leopard is up to date and no changes have been made since yesterday when everything was working. I don't know if there is a better way to perform this task, if there is please let me know. Right now if I close the laptop lid and re-awaken it, it will wake up on the external monitor in a low resolution, then in about 5 seconds it will go back to sleep. Any advice? Thanks.
