What's the problem BTW?

The execution of the operating system is so slow to make it unusable.
No problem with 15.4 RC2 but 15.4 Distribution Release has a regression with VirtualBox with Guest Additions installed on computers that use Intel CPU and Intel GPU.
Please fix this bug.

Could you tell us how did you manage to install the "Guest Additions installed"...

Because I'm stuck with :

Can't find xorg-video-abi-19

Hi @kayoo,
Click on the menu voice "Insert the CD of the Guest Additions" in the menu of VirtualBox while the guest operating system is running.
Run the Resource Explorer of deepin.
Go to the folder of the inserted CD-ROM by using the Resource Explorer of deepin.
Copy the path from the text field of the Resource Explorer of deepin.
Run the terminal of deepin.
login as root with
su -

Paste the path in the following command to change directory.
cd

Execute the following command to run the installer that installs the Guest Additions
run .sh

Follow the Wizard instructions.
It should work, but deepin 15.4 has some bugs with Intel GPU when deepin is virtualized in VirtualBox with Guest Additions installed into deepin.

deepin 15.4 works fine with VMWare with Linux Tools installed.
I think I will switch to VMWare.
Anyway deepin 15.4 does NOT recognize the screen resolution when it is virtualized.
deepin 15.4 does NOT recognize the proxy.
