Why won't virtualbox start on unutu 17.04 (google didn't help)?

Question

virtual box

I open the virtual box, the icon appears in the sidebar and disappears. nothing else happens.
I run through the terminal, and here it is:

[email protected]:~$ virtualbox 
Qt WARNING: Qt: Session management error: Could not open network socket
OpenGL Warning: Failed to connect to host. Make sure 3D acceleration is enabled for this VM.

I set it like this:

sudo apt-get install virtualbox virtualbox-dkms virtualbox-ext-pack virtualbox-guest-utils virtualbox-guest-x11

Then I tried like this, but it didn't work:
sudo apt-get install virtualbox*
