How to Enable GUI in LINUX 7 Inside Oracle VM
How to Enable GUI in LINUX 7 Inside Oracle VM
In this article, we are going to demonstrate how to enable/install GUI mode in LINUX 7.9 in side Oracle VM. This situation occurs when we don’t select the correct available option while installation for GUI/missing require packages.

Follow below step by step to achieve enable GUI.
1. Update requires packages, execute the below command which will update all required packages to the latest along with the latest Linux from ULN.
