Brothers/sisters, how do you do?
I hope I may ask you a question about attaining full screen resolution on Virtual Box 7.0 run with Windows 11 as the host and having used GhostBSD-23.06.01.iso as the guest.
After installing GhostBSD, going to VBox's device menu I insert the Guest Addition. If I understand correctly, I should run VBoxLinuxAdditions.run.

I do the following in the terminal:

I login as root:

logan@Immortality /m/cd0>su
Password:
root@Immortality:/media/cd0#


Elevate permissions:

root@Immortality:/media/cd0 # chmod +x VBoxLinuxAdditions.run


Execute VBoxLinuxAdditions.run
root@Immortality:/media/cd0 # sh ./VBoxLinuxAdditions.run
Verifying archive integrity... 100% MD5 checksums are OK. All good.
Uncompressing VirtualBox 7.0.10 Guest Additions for Linux 100%
VirtualBox Guest Additions installer
Unable to determine correct library path.


As you can see, I get returned the error "unable to determine correct library path."


Following ChatGPT's advice, I try to set the LD_LIBRARY_PATH environment variable using the "fish" set command:

root@Immortality:/media/cd0 # set -x LD_LIBRARY_PATH /usr/local/lib
set: Variable name must begin with a letter.


Hence, I got returned the error: "set: Variable name must begin with a letter."

I am not too familiar with Unix; I hope you may be able to assist me.
I have searched the forum for posts similar to my issue but alas did not find relevant results.

Thank you kindly for your patience and expertise,

For what it's worth, I did try GhostBSD in the free version of VMware player. I was able to install with and also installed xf86-video-vmware. After that, I got full screen with no problem. This was VMware rather than VirtualBox, but it's also free.
