hdmi

I have Macbook Pro with OSX 10.6.8. It is connected to external display (HP 2311x) using Thunderbolt to HDMI cable.

My Macbook display goes to sleep after every 15 minutes of inactivity but the external display won't go to sleep. It does try to go to sleep but wake up immediately. It does that in never ending loop. I have to manually turn off the external display.

Is there some settings I need to change to make external display sleep when Macbook display goes to sleep?

Any suggestions?

Thanks in advance!!

Why does my laptop resume immediately after suspend?

as seen on Ask Ubuntu - Search for 'Ask Ubuntu'
I seem to be having some problem with suspend mode. Every time I try to suspend my laptop, it just locks the screen. Or maybe it successfully suspends just to resume only an instant after. What could cause such a behaviour? I'm running 32-bit Ubuntu 12.04 with the 3.2.0-25 kernel on a HP dv5-1178er… >>> More
