dvi

I have a Dell M4400 connected to a PR03X port replicator/docking station. I use the DVI port to connect it to a first Dell 2208WFP monitor and I'm trying to use a DisplayPort-to-DVI adapter to connect it to a second Dell 2208WFP monitor.

The second monitor, connected via the DisplayPort-to-DVI adapter immediately goes into sleep mode and the laptop doesn't detect it.

What is really weird is that it did detect it the first time I plugged it in but after I unplugged the monitor and plugged it back in it stopped working. I swapped the monitors round and it detected them both but after unplugging the monitor connected via the DisplayPort-to-DVI and plugging it in again it stopped working.

Both monitors work if plugged in directly to the DVI port.

Is there some way to force re-detection? Any ideas?

Why does my laptop resume immediately after suspend?

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

I hope this question doesn't get closed at once :) I have an old laptop, a Compaq NC4200, which is going its final laps around the track these days. Battery is dead, and everything kinda runs slow. It also has only 1GB of memory, and even though I don't know if it can take more, I probably wouldn't… >>> More
