Usb-to-vga
 
Is the n770/n800 capable of connecting a USB2VGA adaptor to it's usb port?
The N800 has a usb 2.0 high-speed port, so there should at least be no usb-bandwith limit.

According to this site:
http://www.nslu2-linux.org/wiki/HowTo/AddVGAAdapter

There are also devices available that support linux...

Anybody an idea?

Let us know when you've got that N800's USB port in host mode... :(

Ok, let's make the assumption the usb-host mode is working, through internally wired cables or an active usb-hub, whatever. Will there be ANY chance that this adaptor may be working, then? :D
Just curious if there is any hope...

Okay, I'll play.

You'll need drivers; I'm assuming that porting the kernel driver and the shell script to OMAP architecture wouldn't be unsurmountable (although the driver is for the 2.4 kernel, so a caveat might be in order). From the comments on the page you quoted, it seems that even after that not everything might be hunky-dory.

The 64K dollar question is obviously: Why?

WHY???
Why does any laptop have an external monitor port?
Suppose you want to edit a photo on a large screen? Or view a document in full-page view. All we have to do is modify the maemo window base class to be expandable and a few details like that. Perhaps add mouse support.

If someone gets this working I'll be quite grateful! In fact, it is on my to-do list, but not for at least a few months.

I figured that, in stead of going for the hardware solution, something like a VNC server on the N800 would be more handy.

No?

Re: Usb-to-vga
 
Yes, but then I would need two computers: the Nxxx and a more expensive one just to run my screen. That implies doing maintainance on the 'screen' computer: ensuring updates are installed, thinking about viruses, etc. The USB screen solution is cheaper, easier and more functional; suppose I want to do a presentation or watch a video on a screen projector? Do I have to bring my 'screen-driver-laptop' to a meeting just to drive the screen?

You convinced me. I want a USB-to-VGA adapter NOW, dammit!!! :rolleyes:

From this thread..
http://www.oesf.org/forums/lofiversi...hp/t11129.html

It looks like there are 2.6 kernel drivers for the usbvga adapters. I am having a hard time finding the actual devices available online or any other info on them.
