您如何找到使用Linux的笔记本电脑屏幕面板制造商/型号？（三星，LG，奇美等）+型号？

我曾尝试在Ubuntu中使用此命令“ lshw”，但似乎没有列出该面板。

谢谢。

使用任何显示EDID信息的实用程序。查找此信息的一个地方是/var/log/Xorg.0.log

谢谢fpmurphy，该日志文件确实在其中引用了面板。有趣的是，一个名为HWINFO64的Windows程序似乎提供了有关监视器“ AU Optronics [型号]等”的详细说明，但Linux Xorg.0.log文件中包含“ AUO”。我希望我能找到与Linux的HWINFO64类似的程序。.仍将您的回答标记为已接受，因为我至少可以将其用作线索，并且它确实表明了品牌。谢谢！

我的信息未显示在XOrg.log中。但是我发现可以从sysfs中公开的Linux内核的DRM（直接渲染管理器）子组件中获取信息。所以我做了以下事情：

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

您可以通过在此处进行一些探测来找出哪些屏幕处于活动状态：

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

然后，我从感兴趣的屏幕中解析了EDID信息，如下所示：

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

我对使用3.18.12内核进行尝试感到失望，并且无法在/ sys / class / drm /内找到任何edid节点。我认为自2013

@MutantBob：我只在3.11上，所以我无法确认您的问题。但是我仍然有drm子目录，并且一些谷歌搜索建议它仍然应该存在。您的内核是否装有DRM模块，并且您有支持它的图形卡驱动程序？unix.stackexchange.com/questions/7622/edid-information还建议尝试使用“ xrandr --verbose”，也许它可以哄骗信息？

用于read-edid在Ubuntu 14.04上获取此信息。 

$ 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.

Looks like i2c was successful. Have a good day.

我在Linux Mint 18.1上发现了两个提供不同结果的工具。首先，我尝试了read-edid：

rich@laptop ~ $ sudo apt install read-edid

有了这个，我得到了以下信息，但是没有找到型号：

rich@laptop ~ $ sudo get-edid | parse-edid
    This is read-edid version 3.0.2. Prepare for some fun.
    Attempting to use i2c interface
    No EDID on bus 0
    No EDID on bus 1
    No EDID on bus 3
    No EDID on bus 4
    No EDID on bus 5
    1 potential busses found: 2
    128-byte EDID successfully retrieved from i2c bus 2
    Looks like i2c was successful. Have a good day.
    Checksum Correct

    EndSection

因此，我尝试了另一种工具来解析EDID：

rich@laptop ~ $ sudo apt install edid-decode

这似乎提供了有关面板模型的更多信息：

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

在Fedora Core上，您可以安装monitor-edid（read-edid软件包似乎仅适用于Ubuntu-建议在此添加Fedora信息，因为该论坛不是askubuntu，而是superuser）。

它输出EISA ID，您可以在Internet上找到供应商和设备信息。
