Great. I'm glad it's working. There's a GhostBSD channel on the Telegram app for other tips and tricks

kldload ig4
kldload iicbus
kldload iichid

Try these commands as root and see it works

Thanks!

Do you have the appropriate module loaded?

Try in a terminal as root

kldload acpi_ibm

If that doesn't work try

kldload acpi_video

And see if that helps

Have you tried okular?

You can try this

Welcome to GhostBSD. Updates are slow due to lack of download mirrors. When GhostBSD gets more financial support this problem will be fixed.

The FreeBSD handbook is a good place. You can also ask questions on the GhostBSD telegram channel
