The partial workaround from Damiƶn works as expected on a Macbook Air 4,2, Ubuntu 11.10. Unfortunately, it also turns off the laptop monitor.
Is there any way to enable the laptop monitor too and use xinerama? I would spend a weekend working on this but I do not have the time. I'm all out of weekends to blow for the next month or two. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-displaylink in Ubuntu. https://bugs.launchpad.net/bugs/812594 Title: HP USB Graphics Adapter (Displaylink) shows green screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-displaylink/+bug/812594/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
