Problem installing guest additions on virtualbox Centos 5.5 64bit guest
 

I am using a windows (is that a bad word here?) 32bit host to run a CentOs 5.5 64bit guest. The problem is I cannot get seamless mode or full screen mode to work. When I initially tried to install guest additions for Linux it wouldn't complete installation due to missing xorg files so I ran "yum groupinstall "X Window System" and ran the installation again. The installation then seemed to complete properly however after rebooting I still have no seamless mode or full screen. To install I used the instructions on this website http://www.if-not-true-then-false.co...s-red-hat-rhel

I also have a 32bit windows guest running with guest additions installed and running as you would expect.

Any help would be greatly appreciated

Just to add, I have already done everything suggested in this thread:

Anyone ? Have I come to the wrong place with this issues ?
