जवाबों:
किसी भी उपयोगिता का उपयोग करें जो EDID जानकारी दिखाता है। इस जानकारी को देखने के लिए एक जगह /var/log/Xorg.0.log है
मेरी जानकारी XOrg.log में दिखाई नहीं दी। लेकिन मुझे पता चला कि मैं डीआरएम (डायरेक्ट रेंडरिंग मैनेजर) से जानकारी प्राप्त कर सकता हूं, जो कि लाइनक्स कर्नेल का उपसमुच्चय है, जो sysfs में उजागर होता है। तो मैंने निम्नलिखित कार्य किया:
root@dark:~# ls /sys/class/drm/
card0 card0-DP-2 card0-eDP-1 card0-HDMI-A-2 card0-VGA-1 version
card0-DP-1 card0-DP-3 card0-HDMI-A-1 card0-HDMI-A-3 controlD64
आप यह पता लगा सकते हैं कि कौन सी स्क्रीन यहां कुछ जांच कर सक्रिय हैं:
root@dark:/sys/class/drm# cat card0-HDMI-A-2/enabled
enabled
root@dark:/sys/class/drm# cat card0-HDMI-A-3/enabled
disabled
मैंने तब स्क्रीन से EDID की जानकारी प्राप्त की जिसे मैं इस प्रकार से रूचि ले रहा था:
root@dark:/sys/class/drm# cat card0-HDMI-A-1/edid | edid-decode

महान सफलता!
read-edidइस जानकारी को Ubuntu 14.04 पर प्राप्त करने के लिए उपयोग किया जाता है।
$ sudo apt-get install read-edid
$ sudo get-edid | parse-edid
This is read-edid version 3.0.1. Prepare for some fun.
Attempting to use i2c interface
No EDID on bus 0
No EDID on bus 1
No EDID on bus 2
No EDID on bus 3
No EDID on bus 4
No EDID on bus 5
3 potential busses found: 6 7 8
Will scan through until the first EDID is found.
Pass a bus number as an option to this program to go only for that one.
256-byte EDID successfully retrieved from i2c bus 6
Looks like i2c was successful. Have a good day.

लगभग sys / sys / class / drm / card0 एक आसान विकल्प लगता है।
cd /sys/class/drm/card0

मुझे लिनक्स मिंट 18.1 पर दो उपकरण मिले जो अलग-अलग परिणाम देते हैं। पहले मैंने रीड-एडिड की कोशिश की:
rich@laptop ~ $ sudo apt install read-edid
इसके साथ मुझे निम्नलिखित मिला, लेकिन यह मॉडल नंबर नहीं मिला:
rich@laptop ~ $ sudo get-edid | parse-edid
This is read-edid version 3.0.2. Prepare for some fun.

तो फिर मैंने EDID को पार्स करने के लिए एक और उपकरण की कोशिश की:
rich@laptop ~ $ sudo apt install edid-decode
यह पैनल के मॉडल के बारे में अधिक जानकारी देता प्रतीत होता है:

फेडोरा कोर पर आप स्थापित कर सकते हैं monitor-edid( read-edidपैकेज केवल उबंटू के लिए उपलब्ध लगता है - मेरा सुझाव है कि फेडोरा की जानकारी यहां जोड़ दें क्योंकि यह मंच नहीं है askubuntu, लेकिन superuser)।
यह आउटपुट करता है EISA ID, जिसके साथ आप इंटरनेट पर विक्रेता और डिवाइस की जानकारी पा सकते हैं।
