Window autoscaling fail vBox 5.0.10

[radek]

VirtualBox 5.0.10
Host: Windows 7 x64
guest: Ubuntu 14.04.3 x64
GuestAdditions: installed

Autoscaling guest window was working after installation Vbox addons but i did sudo apt-get update, sudo apt-get upgrade and after reboot it didn't work. I installed addons once again (i run addons disc) but it doesn't help.

In guest setting Displays i have short list with window resolutions to choose.

Please help, how to reinstall guest addons on Ubuntu, maybe it helps.
