Hello vhp1
Thanks for contacting us with your problem.
1. Have you added a workaround for recent X problems as described in
http://support.displaylink.com/knowl...ent-x-upgrades [Workaround 2]? Please remember to reboot your computer after adding a conf file.
Did it resolve your problem? If not...
2. Does this problem still exists after logout/login or reboot your computer with device attached to it?
Waiting for your reply,
Adam
