Hi,

Not 100% sure if this issue is cause by Bumblebee, but thought I'd check.

Basically, I've installed Bumlebee and most things are working well. However, when I connect up an external screen via the mini displayport (via a mini DP to HDMI connector), the screen comes up fine - with sound - but keeps going from being on to being off. This is kept going - 10 seconds on, 10 seconds off.

Like I said, I'm not 100% sure if this is being caused by Bumblebee, but I thought it was best to check.

Linux Mint 12 64 bit - newly installed yesterday
