EDID 정보를 표시하는 유틸리티를 사용하십시오. 이 정보를 찾을 수있는 곳은 /var/log/Xorg.0.log입니다.
내 정보가 XOrg.log에 나타나지 않았습니다. 그러나 나는 리눅스 커널의 DRM (Direct Rendering Manager) 하위 구성 요소에서 정보를 얻을 수 있다는 것을 알았습니다.이 구성 요소는 sysfs에 노출되어 있습니다. 그래서 나는 다음을 수행했다.
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
여기에서 몇 가지 조사를 수행하여 활성화 된 화면을 파악할 수 있습니다.
root@dark:/sys/class/drm# cat card0-HDMI-A-2/enabled
enabled
root@dark:/sys/class/drm# cat card0-HDMI-A-3/enabled
disabled
그런 다음 관심있는 화면에서 EDID 정보를 다음과 같이 파싱했습니다.
root@dark:/sys/class/drm# cat card0-HDMI-A-1/edid | edid-decode

read-edid
Ubuntu 14.04에서이 정보를 얻는 데 사용 됩니다.
$ sudo apt-get install read-edid
$ sudo get-edid | parse-edid

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.

Linux Mint 18.1에서 다른 결과를 제공하는 두 가지 도구를 찾았습니다. 먼저 read-edid를 시도했습니다.
rich@laptop ~ $ sudo apt install read-edid
그것으로 나는 다음을 얻었지만 모델 번호를 찾지 못했습니다.

그런 다음 EDID를 구문 분석하기 위해 다른 도구를 시도했습니다.
