Ubuntu 20.04；如何导入颜色配置文件

我希望能得到帮助，找到适用于 20.04 的描述，因为这三个页面具有相同的文本：

Add profile首先，在我长期稳定的 20.04 中没有。（参考上面的文字）

我有一个使用以下方式创建的个人资料

$ flatpak list
...
DisplayCAL        net.displaycal.DisplayCAL       3.8.9.3 ...

...我不知道如何使用它。

$ dispwin -d 1 profile-name #fails to install the profile

添加-D似乎并没有说明任何失败......只是它在最后“成功了”。

哦...

Dispwin: Warning - new_dispwin: Expected VideoLUT depth 11 doesn't match actual 10
new_dispwin: DirectColor fdepth 8, rdepth 11, ndepth 10, edepth 16, r/g/b shifts 16 8 0

... 在其中；但警告是否足以阻止它呢？

实际的 dispwin 运行：

$ dispwin -D2 -d 1 -I profile-name # Long complicated name replaced

找到描述和看似相关的信息：

根据在中可见的“desc”字段strings step4.icc，也在创建配置文件时在 DisplayCal（GUI）中的文本字段中，并且作为原始文件名：

现在，有一些进展...
将 icc 文件移动到 colord 的存储区，将其重命名为更短的名称，然后...

$ cd /usr/share/color/icc/colord 

$ sudo mv '2023-04-22 11-07 -- LP173WFG-SPB1 #1  2.2 VF-F XYZLUT+MTX' \  
step4brightness.icc

$ colormgr find-profile-by-filename step4brightness.icc

... 和我终于有一个无错误的“设备添加配置文件”。

配置文件及其全名（存储在文件中）显示在Settings > Color > display-name

我将检查这是否会对我在 Epson 3880 上的打印造成影响，例如从 GIMP
