I'm having a hard time finding reliable info on this subject, but I'm looking for a usb to vga ( or dvi ) adapter for a Ubuntu 10.10 installation on a laptop.

I'm currently using the regular vga external port of my laptop so I have a dual video output but I'd like to a third monitor attached to this setup.

Note: The 2 monitor that I've got are wide resolution so the dualhead2go is not giving me enough workspace making the resolution really poor and uncomfortable.

Thanks for your comments,

What do you mean by "wide resolution" (that expression makes no sense in English) and why does that mean the dualhead2go is not good enough? – JanC Oct 21 '10 at 19:29

I can't point you to a device that definitely works but a lot of them use chipsets that are compatible with the (in Ubuntu included) module sisusbvga.

You can read more about it (including example companies and chipsets) HERE.

Basically you need to sudo modprobe sisusbvga and then it should work after editing your xorg.conf to tell your linux how to treat the new device.

Thanks for the info, I've taken the chance of ordering a dell device... I'm going to test your suggestion and let the community know about... – Phil R Oct 22 '10 at 18:07
