This is because let's assume that OpenChrome is buggy, but VIA Technologies in house device driver is working properly. I2C bus is typically used as the first option for display detection, including VGA monitors (CRT or LCD does not really matter). When I read VIA Technologies in house device driver log, it appears that it is also not seeing your VGA monitor via I2C bus, hence, it is resorting to the use of what you called a "fake" monitor information. Actually, this type of situation does happen, and I recently had another person file a bug report similar to your situation (<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>). Personally, it will be nice if you can attach a different monitor with VGA interface to this unit to see what it does. Regarding the monitor type, CRT or LCD does not matter to OpenChrome since EDID that comes from any VGA interface will always identify as an analog type interface (and this also assumes that it is working properly in the first place), and this is used by other Linux device drivers to detect a VGA interface as well. If you are able to borrow another monitor (CRT or LCD) with a VGA interface, you may want to attach that to see if OpenChrome will recognize the monitor or not. If not, I think there is a high probability that there is a problem with the unit. Another possibility can be hardware level incompatibility, but I will not want to go there for now. I do know people do think that OpenChrome is suspect, and that is not a bad assumption considering that bugs have multiplied over the years without much repairs being done until now. However, even the better quality VIA device driver (They do have in house help in writing the device driver from the hardware design side. That's a huge advantage they have over the previous OpenChrome developers and me.) is not detecting your VGA monitor, and I find that concerning.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
