Hi all

I installed Oracle Enterprise Linux 5 in Virtual Box.

And I wanted to change resolution of screen, but there are only options - 800x600, 600x480

I googled what configuration do i have to and internet says

1. add 1024x768 in Modes in /etc/X11/xorg.conf

2. add the parameter "resolution=1024x768" to the kernel line in grub.conf

3. Add the parameter "video=1024x768" to the kernel line in grub.conf.

So I tried all.

# ki-tae, for resolution

resolution=1024x768

video=1024x768

after rebooting the virtual machine, i checked "Screen Resolution Preferences" and "Display Settings"

But the options are not different before setting above.

what do I have to do to extend resolution ???

Thanks & Regard.

p.s

"init" command is not recognized in my OEL.

should i install another rpm??
