    登录Deepin后出现黑屏。 我花了半天时间解决问题，但没有运气。 如何解决这个严重的问题？ 这是Deepin 15.11的最新版本。我只是注意到可以看到屏幕，但几乎看不到。 它似乎在透明度非常低的黑色面板下。

    I get a black screen after sign in Deepin. I spent half of the day resolving the problem without luck. How to solve this serious problem? This is the latest version Deepin, 15.11.  I just notice that I can see the screen, but barely. It seems to be under a black panel with very low transparency. BTW, I was thinking of purchasing a Hauwei Deepin OS laptop. With my current experience of this Deeping problem, I need to rethink my plan. There is not any response after I post my question for three days. I don't want to buy a product without reasonable support.

    Thanks for the info.

    The output of those two commands are the followings (with the USB Live boot):
    1. deepin@Deepin:~/Desktop$ ls -l /sys/class/backlight
    2. total 0
    3. lrwxrwxrwx 1 root root 0 Nov 26 18:40 acpi_video0 -> ../../devices/pci0000:00/0000:00:01.0/0000:01:05.0/backlight/acpi_video0
    4. deepin@Deepin:~/Desktop$ cat /sys/class/backlight/*/*brightness*
    5. 7
    6. 7
    7. 7
    8. deepin@Deepin:~/Desktop$
    Copy the Code
    The problem, again, is that the screen turns dark after signing into Deepin.
