VirtualBox installing Ubuntu 14.04 Unable to adjust resolution issues

Basic Environment

Hosting System: Windows 10

Virtual machine system: Ubuntu 14.04-32bit, Ubuntu 14.04-64bit

virtualbox:5.2.0 r118431 (Qt5.6.2)

Problem description
When Ubuntu 14.04 is installed by default, click "Device" on the menu bar and select "Enhanced features". After the installation in Ubuntu to see the prompt to restart the system, but after the restart is complete still only 640x480 a resolution, unable to adjust adaptively. 14.04 of the 32-bit, 64-bit are the same problem. In the same environment, the installation of 12.04, 16.04 normal.

Problem solving
Notice that the installation of the enhancements is prompted by the terminal to see/var/log/vboxadd-setup.log check for problems with the installation. There is no such hint for normal installation. Then open the log file, skip to the last view, sure enough compile error. Is a mistake like this: implicit declaration of function ' ASSERTRC '.

Then search for this error. My idea is to fix this compilation error by installing the appropriate environment. But in the installation package can not find the relevant source code, do not know where the source code compiled here. Then find this post on the official website: https://www.virtualbox.org/ticket/17163, that's the problem. But the discovery was discussed and no solution was given. Later only to know, in fact, there is a reply to the solution, but did not realize that also applies to 14.04.

Then go to the official website to download the page to see if there are updates. Then saw this passage: Update:the Guest additions image with the 5.2.0 release fails to work with recent Linux Guest kernels. So I immediately tried out the new enhancement package it offered.

After you start the system, click on the disc icon in the sidebar to install the enhancement again, and then do not see the prompt to check the/var/log. Reboot the system, log in and see the adaptive large resolution. Problem Solving!
