Hi, I am testing for a while now. The kernel driver seems to load just fine and I get the green display. I tried the driver in linux-2.6.38 and the one that's provided by freedesktop displaylink-mod-0.3 together with xf86-video-displaylink-0.3 If I set the usb monitor as the main display, using the kernel module, it crashes (I attached the complete Xorg.0.log.crash). This can be reproduced.

Which brings me to my second problem, I cannot get Xorg to use the second display. It just stays green and I do not get the second screen going. I attached my current xorg.conf where I tried several different things already, like with xinerama and without, with screen numbers and without, with fbdev option and without etc. There must be some option I am totally missing out or it doesn't work with my versions? I read people had less problems with the kernel module 0.2.3 and nvidia? I am running out of ideas now... -- cheers, Marcus Xorg.0.log.crash: <a href="http://ompldr.org/vODRzZQ">http://ompldr.org/vODRzZQ</a> current corg.conf: <a href="http://ompldr.org/vODRzZw">http://ompldr.org/vODRzZw</a>
