If xorg could just get a patch to look to the usb bus as well as the pci bus then these display devices might work better.
The problem I'm having with 12.04.1LTS are: 1) the displaylink device only works with the Intel integrated graphics. Both nVidia and AMD proprietary drivers ignore the displaylink device 2) with the displaylink Intel graphics combination you must set the vgascreen to LeftOf the displaylink device in xorg.conf otherwise Unity goes completely wonky splitting the screen into 3 inequal parts then opening windows off screen not under the mouse. 3) lightdm surprisingly doesn't have too much trouble with the DisplayLink device. -- 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 : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
