I'm using a TripleHead2Go to host 2 1920x1080 monitors as one massive 3840x1080 display in addition to my laptop's 1920x1200 display. If I try boooting with it plugged in, however, it hangs and never makes it to the login screen.
Things basically completely hang right before displaying the login screen; they seem to hang indefinitely. I have no idea why this adapter is causing things to hang. I was able to get the log by simply booting to a root shell and starting lightdm like so:
(sleep 30 && cp /var/log/Xorg.0.log ~/Desktop) &
sudo service lightdm start
Here's the whole log, available on pastebin. The display is DFP1, I believe.
What's going wrong here?
