Samsung monitor doesn't show anything. Led in the power button just blinks.. It seems no input at all. I can start X clients on both screens, so X started with two screens properly. I helped "muchman" to setup his dual screen monitors, so I hope I also have correct X configuration ;) What is the relation between libdlo and udlfb (displaylink-mod) ?

Is that the case? There are a number of problems unique to Ubuntu 9.04's versions of GDM and Gnome. Roberto mentioned one of these problems in an earlier post, and I've seen several with multiple displays and multiple X Servers on 9.04. Will try to get more complete notes at <a href="http://libdlo.freedesktop.org/wiki/Ubuntu9.04" target="_blank">http://libdlo.freedesktop.org/wiki/Ubuntu9.04</a> Please feel free to add any info you also discover.
