Linux ile bir dizüstü bilgisayar ekran paneli üreticisi / modeli nasıl bulunur? (Samsung, LG, Chi Mei, vb.)

Linux ile bir dizüstü bilgisayar ekran paneli üreticisi / modeli nasıl bulunur? (Samsung, LG, Chi Mei, vb.) + Model numarası?

Ubuntu bu komut "lshw" kullanarak denedim, ama orada panel listelenmiş gibi görünmüyor.

Teşekkür ederim.

EDID bilgilerini gösteren herhangi bir yardımcı programı kullanın. Bu bilgiyi aramak için bir yer /var/log/Xorg.0.log

Bilgilerim XOrg.log dosyasında görünmedi. Ancak, bilgiyi linux çekirdeğinin DRM (Direct Rendering Manager) alt bileşeninden alabileceğimi anladım. Bu yüzden aşağıdakileri yaptım:

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

Burada biraz problama yaparak hangi ekranların etkin olduğunu anlayabilirsiniz:

root@dark:/sys/class/drm# cat card0-HDMI-A-2/enabled 
enabled
root@dark:/sys/class/drm# cat card0-HDMI-A-3/enabled 
disabled

Daha sonra ilgilendiğim ekranlardan EDID bilgilerini aşağıdaki şekilde ayrıştırdım:

root@dark:/sys/class/drm# cat card0-HDMI-A-1/edid | edid-decode

Büyük başarı!

Eğer yükleyebilirsiniz salt EDID , o zaman birlikte deneyebilirsiniz get-edid | parse-edid.

read-edidBu bilgiyi Ubuntu 14.04'te almak için kullanılır .

$ sudo apt-get install read-edid
$ sudo get-edid | parse-edid
This is read-edid version 3.0.1. Prepare for some fun.

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 18.1'de farklı sonuçlar veren iki araç buldum. Önce okuma-düzenleme denedim:

rich@laptop ~ $ sudo apt install read-edid

Bununla aşağıdakileri aldım, ancak model numarasını bulamadı:

rich@laptop ~ $ sudo get-edid | parse-edid
    This is read-edid version 3.0.2. Prepare for some fun.

Sonra EDID ayrıştırmak için başka bir araç denedim:

rich@laptop ~ $ sudo apt install edid-decode

Bu, panel modeli hakkında daha fazla bilgi veriyor gibiydi:

rich@laptop ~ $ sudo get-edid | edid-decode
