Check Oracle E-Business Suite Installation and Upgrade Notes Release 12 (12.1.1) for Linux x86-64 (Doc ID 761566.1)

Make sure you installed all the required rpms for your OS and applied the patches for your OS (if there are documented for your OS in that document)
Especially, the rpm "xorg.........."

Follow the documents line by line, dont skip anything everytime you need to do an operation in any Oracle system.
