You can use the Linux binary. Follow this two guides. https://www.micski.dk/2021/12/21/install-ubuntu-base-system-into-freebsds-linux-binary-compatibility/ and then https://www.micski.dk/2021/12/22/install-and-run-signal-desktop-application-on-freebsd/ Works great for Signal Desktop (I using it) and...

Another alternative to solving the "hit the bus" or even a "rapture" scenario is to add GhostBSD specific applications to FreeBSD ports as early as possible. These applications could be maintained and used by a wider audience.

I'm running GhostBSD on a Lenovo X240 Thinkpad just now (writing this message).

Works great.
Even suspend works (little slow, I see console first, then it switches back to Mate Desktop).
