i’m using linux on a laptop with an GF108M [GeForce GT 525M] graphics chip and the nvidia driver 319.60 under Ubuntu 13.10.
The laptop is connected to a tv with hdmi. I configured the laptop so, that the tv is the only display used and the internal display is disabled. The laptop is used as a server and should run all the time.
Now, when I turn of the tv, the nvidia driver seems to automatically switch to the internal display, because the tv has gone. I don’t want this. I don’t want the internal display to be used at all in any case. Can I disable that automatic behaviour somehow?
The problem first came up after I from Ubuntu 12.10 with an old nvidia driver (I don’t know the exact version), to Ubuntu 13.10 with a more recent nvidia driver. Before that, there was no automatic switching.
Thanks in advance for any help
