Hi there, I struggled a long time trying to get my usb monitor working this days... And luckily I got it work (some kind) today, with static xorg configuration files.
The kernel came with my system (Debian 7, a new installation. That also applies to Debian 6 iirc) recognized the monitor and used udlfb as driver to provide a framebuffer node at /dev/fb1. The X system worked with using fbdev as xorg driver if write the configuration manually, but xrandr could not find that monitor without a static screen configuration. And simply include a static config for only the displaylink monitor will suppress the auto detection to other monitors, and the the framebuffer one whould be the only screen avaliable to X environment, which is not good. What I want to do is to find a way to tell X.org to treat the /dev/fb1 in a hot-plugable manner, which allows me to configure my screen settings on the fly, since I'm using Debian on my laptop and the moniter setup varies from time to time. Any idea about how to do it? --------------------- Posted by Haochen Xie
