In case you lack of GPU acceleration on GhostBSD 25 and FreeBSD 15 using Linuxulator, it is caused by a bug in that component where it does not expose correctly the video cards to the system.
There is this workaround, but has some lines that have to be fixed, depending where you want install the script, before it can work.
Below I put a guide how fix and install the script.
Contact me if you spot errors or if the passages are not clear.

You can install the script replacing the system one, caller "linux", or use it as a parallel service and disable the default one.
All commands have to be done with superuser privileges, with sudo from normal user or switch to root with "su"
For replace the original system script
1 - Create a backup of the original file.
cp /etc/rc.d/linux /etc/rc.d/linux.backup

2 - Replace the old script with the new one.
You can delete first the old file with
rm /etc/rc.d linux
then open a text editor, copypaste the script and save the new file as linux.
ee /etc/rc.d linux
Or you can open the old file with a text editor, copypaste the new script over the old, and overwrite the original file.
3 - Edit these lines in the script:
Line 11:
name="linux"
Line 13:
rcvar="linux_enable"
Then save (or overwrite) the file.

4 - Set the permission of the linux script if they are different, as precaution.
chmod 555 /etc/rc.d/linux
5 - Enable two services in rc.conf.
Open rc.conf with a text editor
ee /etc/rc.conf
then add if these are missing or set different:
linux_mounts_enable="YES"
linux_vulkan_enable="YES"
each entry on a single line, follow the formatting and do not change it.
Save the changes.
6 - Reboot

If you want set up a parallel service, without modify the file, this option is safe because updates could change the linux script.
The procedure has little differences.
1 - You can put the script with a new name, without delete or overwrite the original one, both in the main system folder
/etc/rc.d
otherwise, much better and highly advisable on a BSD system, under the software folder
/urs/local/etc/rc.d

2 - Open the text editor, copypaste the workaround, and save it with a new name in one of the folders above. You can give the script a new name, but you have to keep the name consistent everywhere inside the script.
ee /usr/share/etc/rc.d linux_vlk
3 - Edit these lines:
Line 5:
# PROVIDE: linux_vlk
Line 13:
rcvar="linux_vlk_enable"
Line 110
linux_vlk_start()
Save (or overwrite) the file.

5 - Enable two services in rc.conf.
Open rc.conf with a text editor
ee /etc/rc.conf
then set
linux_enable="NO"
and add
linux_vlk_enable="YES"
also check if these are missing or set different:
linux_mounts_enable="YES"
linux_vulkan_enable="YES"
each entry on a single line, follow the formatting and do not change it.
Save the changes.
6 - Reboot
