From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.7) Gecko/20050414 Description of problem: For all digital sony monitors I have tested /var/log/Xorg.0.log returns the same and wrong serial number! Version-Release number of selected component (if applicable): xorg-x11-6.8.2-1.FC3.13 How reproducible: Always Steps to Reproduce: 1. start X 2. 3. Actual Results: every digital sony monitor returns the same serial number: (--) NV(0): DDC detected a DFP: (II) NV(0): Manufacturer: SNY Model: 1690 Serial#: 16843009 Expected Results: The serial numbers should be different and the same as indicated by the monitor Additional info: - a google search on "Manufacturer 16843009" gives quite a number of different monitors with the same serial number! - 16843009 = 0x01010101
The monitor serial number is not used for anything at all. It's just a cosmetic number. This is very highly likely to be a flaw in the monitor itself and not a software bug. There are a lot of Sony monitors out there that are known to provide flaky EDID data. Every monitor model is supposed to have it's own unique EDID, however there are a lot of Sony monitors that they did not change the ID on. There's a block of them that all claim to be SNY0000 or SNY0001 or something similar (I don't remember the exact code, but it's in MonitorsDb IIRC). So this is 99% unlikely to be a bug in the X server or video driver, and much more likely to be a flaw in the monitor itself. If someone cares enough to debug this far enough (which would require having the actual monitor it occurs on), and can determine that it is really an X bug, they should file a bug report in X.org bugzilla at: http://bugs.freedesktop.org in the "xorg" component It's not something worth wasting our time on however, as the serial number isn't actually used for anything as I've indicated above. Setting status to "NOTABUG".
I assume it ist 89% likely to be a bug: 1. It works with nearly all monitors when they where connected to the analog port. 2. it is very unlikely that different monitors give the same number as a search of google will show "Manufacturer 16843009" 3. They all return the correct Model: SNY0490,SNY1690,... And I like the reported serial number, as I they allows a correct inventory for all the monitors I am resposable for. But, ok, severity is shurely low, and maybe someday I have the time to trace the code - maybe next year ...
If you are convinced it is a bug, report it to X.org bugzilla as suggested in comment #1. It is a cosmetic very low priority issue at best. If it is determined by X.Org developers to be a real bug after you report it there, and if they fix it, we will review any patches someone points out and consider them for future updates. Changing status to "WONTFIX", because if this really is a bug, we're not going to dedicate resources to a minor cosmetic issue of this nature.
After reading the specs and the code I have to admit that the version 1.3 will no longer use this location for serial number. It is writen some bytes later and Xorg will show it some lines below. It is all correct and works fine with all monitors.
