Please also note that very same monitor supplies EDID data to same openchrome-0.4.0 driver when connected to VGA port of CLE266/CN700/VX800 devices as seen on my previous logs. Yet I have tested a third monitor today (Philips 107E) on T5540(VX800) and T5550(VX900) and I will send the logs shortly. I understand that CRT and LCD are same regarding detection. Then maybe LCD monitors behave better on providing EDID data simply because they are never products than CRT monitors. I have also tried applying a patch to openchrome-0.4.0 just like Benno did previously at <a class="bz_bug_link bz_status_NEW " title="NEW - driver does not detect VGA monitor, but there is one" href="show_bug.cgi?id=94277">Bug 94277</a> and I am able to get image on same VGA moitor connected to DVI port of T5550. Sure its not getting any EDID data by this way, but blindly setting some modes as via-opensource driver did. I will send the patch and log files shortly. What I understand so far is, there is some shortcomings in getting EDID data from (some) VGA devices connected to DVI port of VX900 (or maybe any DVI port in general). So, IMHO, it may be better to implement a mechanism to fallback to default modes and let the user set other modes in xorg.conf rather than trying to get EDID data from any and all monitors. At this point, it will be a good practice to support as much resolutions as possible in fallback. Because although one of my monitors (not the ones I have sent the logs) supports 1600x1200, I can get upto 1280x1024 by via-opensource driver and upto 1024x768 by modified openchrome-0.4.0 driver as they provide only upto these resolutions.
