>I have a Macbook Pro that I use as my "teaching machine".  It is wired and hooked to my SmartBoard.  I have a session in VirtualBox that boots to the network via PXE and thus acts as a thin-client.  Since the thin-client is "also" on the Mac...my SmartBoard software running on the Mac will also control the thin-client in VirtualBox....again....life is good.  HOWEVER...since the thin-client is running in a VM I can only get 1024x768 resolution unless I do something like install VirtualBox Guest Additions.  My question is....is there anyway I can force the resolutiuon for the thin-client running in Virtualbox either via lts.conf...or is there a way to install the VirtualBox Guest additions so I can get a more acceptable resolution like 1440x900?  Any ideas welcome.

Hi David,

I use a MacBook for exactly this purpose at our school - in fact I've set up all teacher MacBooks this way.

I was getting 800x600 on VirtualBox and I spent ages trying to sort it with Guest Addon tools. 

*I didn't need those tools in the end, all I had to do was...*

I set the following in my lts.conf:

[macbook]
X_MODE_0 = 1024x768
X_HORZSYNC = 30-95
X_VERTREFRESH = 55-65

[08:00:27:04:3C:1A]
LIKE=macbook

Obviously, the hardware address above is the virtual hardware address set by VirtualBox.

I haven't tried setting above that resolution, so I'd be interested to hear your results.
