It's usually better and faster, if issues like this one (configuration, question) get first addressed in the ​VirtualBox forums. More than 95% of the issues are resolved over there, which keeps the developers focusing on the bug fixes and enhancements, and there is no need for another ticket to keep track of. For example, yours is most probably not a bug and someone from the developers has to deal with it and close it as "Invalid".

If the 2D box is greyed then VirtualBox cannot make use of 2D acceleration. If you are using the .deb package from download.virtualbox.org/virtualbox then there should be an application /usr/lib/virtualbox/VBoxTestOGL which is used to test if the host supports 2D video acceleration (which is only supported for Windows guests btw). You might want to execute

/usr/lib/virtualbox/VBoxTestOGL --test 2D --log log.txt

and have a look at log.txt.

I have NVIDIA Corporation GeForce GT 620 [10de:0f01] (rev a1) and installed the latest driver version 375.66

Then Problem is always not resolved

Conclusion : button 2d acceleration always grayed.

I downgrade from 5.1.22 into 5.0.40 then the problem is fix it.

[Frank Mehnert]

Thanks for the information. I think we found and fixed the problem. Could you install this test build and confirm that it fixes your problem?

I try the version 5.1.23 ,then the button "2d acceleration" is now black (not grayed), (operational).
J'ai tester la version 5.1.23 , le bouton "accélérateur 2d" est maintenant activable.

Fix is part of 5.1.24.
