This was true until drm-next-kmod and drm-stable-kmod ports appeared. Now you have very similar Linux and FreeBSD graphics experience.
> This also means relatively limited support for Wayland, so you have to use X11, which is insecure.
Wayland is enabled by default since recently.
As we talk about security...
* Linux - Vulnerabilities (2103) - https://www.cvedetails.com/vendor/33/Linux.html * FreeBSD - Vulnerabilities (368) - https://www.cvedetails.com/vendor/6/Freebsd.html
About 7 times more on the Linux side, do not mix X11 into that :)
FreeBSD as every system has its limitations, that is for sure, but as I track its developments of the span of 15 years its just getting better and better, in all aspects - including desktop.
Of course there are 'environments' where its all or nothing like 'mobile', Linux has most of the market here with Android while FreeBSD has nothing.
