Vendor monitor strings with double quotes break XF86Config
Last modified: 2007-04-18 12:41:14 EDT
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.8) Gecko/20020204 Description of problem: I just worked at configuring an IBM LCD monitor whose name included a double quote (They were being cute to say it was a '17"' monitor. The code in XConfigurator that fetches the vendor strings has to get a bit more clever to filter out that double quote, because the resulting XF86Config files would say "IBM 6251 LCD 17"" And that chokes XFree86. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.Run Xconfigurator on an IBM NetVista X series system. 2.View the error messages from the X server when it chokes on the syntax error. Additional info:
I can't find that string located anywhere in any of the hardware databases. Where exactly is this string coming from?

Since the data provided doesn't seem to exist in any current databases, I am assuming that the problem no longer exists in Rawhide using the latest versions of Xconfigurator and hwdata (new package).
I have not studied this very deeply, so I'll ask: When one does a VESA query of a video monitor to have it describe itself, isn't there a string returned as the name of the hardware? It was my guess that the string returned by the monitor contained a double quote, and that that string was being passed to soemthing that was crafting the Monitor section of XF86Config. Am I being silly here? -wdc
The X server does a DDC probe of the monitor if the video card supports doing such. If the monitor supports DDC, then the monitor's EDID info is returned and the EDID value is looked up in the MonitorsDB database. The EDID value is typically a string of 7-8 characters generally in the form xxxnnnn. The field you are refering to is only a textual string for humans to read, and is not involved in the autodetection process.
This is very perplexing. Well the system I was playing with was a loaner. We sent it back. If the problem happens with something I care more about, I'll do additional sleuthing. Thanks very much for the help and the clarification.
