Thanks very much for the assistance.<div><br></div><div>I'm using fbdev now -- I am able to get the green screen to display when the USB device is plugged in and X server is already running, but I can't get it to work in my xorg.conf. I have a suspicion that it's because my device loads as /dev/fb1 when I plug it in, yet when X starts, /dev/fb1 isn't available yet.</div> <div><br></div><div>I get this error:</div><div><br></div><div><div>xf86OpenConsole: VT_WAITACTIVE failed: Interrupted system call</div><div><br></div>Strange...

It is not supposed to be used by end users. displaylink_drv.so is an older displaylink Xorg driver. Newer one is a modified fbdev driver.
