In VirtualBox 5.0.10, Fedora 23 cannot automatically adjust the Virtual Machine resolution after the Enhancement Tool is installed. virtualbox5.0.10

Fedora 23 is installed in VirtualBox 5.0.10. Even after the Enhancement Tool is installed, the virtual machine cannot automatically adjust the resolution according to the running window size of VirtualBox. The main reason is that the Xorg Display Server version of Fedora 23 is too high. Currently, VirtualBox 5.0.10 is not supported. There are two solutions:

1. Wait for the new version of VirtualBox to upgrade and support the latest version of Xorg.

2. downgrade the Xorg package version that comes with Fedora 23 to the version that comes with Fedora 22 to solve the problem. The specific method is as follows:
Dnf -- showduplicates -- allowerasing -- releasever = 22 downgrade xorg-x11-server-Xorg
Run this command.
