Attached is the dmesg from my laptop. <div class="gmail_quote">On Wed, Jul 8, 2009 at 11:30 AM, Bernie Thompson <<a href="mailto:bernie@berniethompson.com">bernie@berniethompson.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Hi Jason, If you're able to get any pixels at all on the Samsung LD190G over USB (e.g. xterm), then it sounds like udlfb and the x server on top of it are doing their job -- sounds like it's down to the thorny issues of X configuration, etc. on top of them. 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. Thanks, Bernie <div><div></div><div class="h5"> On Wed, Jul 8, 2009 at 10:20 AM, jasonlife<<a href="mailto:jasonlife@gmail.com">jasonlife@gmail.com</a>> wrote: > I have tested this new version with my Samsung LD190G, but it still doesn't > work properly. > > I tested the monitor on my laptop with Ubuntu 9.04.
