I installed VirtualBoxAddition and i still cant have resolution higher than 800x600 in full-screen mode. I did it in various ways
- Input , Insert Guest Addition CD, or by downloading iso and opening it from inside VM
- Then i tried typing in terminal either sudo ./VBoxAddition.run or sh ./VBoxAddition.run
There goes few lines, which last is "Starting Virtual Box Addition" and no errors. After rebooting CentOS, whole VM or even host computer i still cant enable 16:9 resolution by Auto-Resize. I also checked for logs in cd /var/log There are few of them - vboxadd-install.log - vboxadd-setup.log - vboxadd-setup.log.1 - vboxadd-setup.log.2 - vboxadd-setup.log.3 - vboxadd-setup.log.4 - vboxadd-unintall.log
Inside them: (checked by nano )
groupadd: group 'vboxadd' already exists
Removing existing VirtualBox kernel modules.
vboxadd-setup.log.3 Removing existing VirtualBox kernel modules.
vboxadd-uninstall.log is empty.
Could anyone please help me, i dont know what to do to get full screen 16:9 resolution on my computer in Centos & Virtual Box?
