FreeBSD 12 Xorg vs X11SSH-F / AST

[O'Connor, Daniel]

Hi,
We have a Supermicro X11SSH-F motherboard which has a ASPEED AST2400 video chipset with FreeBSD 12.0-RELEASE r341666 GENERIC amd64 on it.
Unfortunately I am unable to get X working with it properly, I have the xf86-video-ast package (version 1.1.5_2) installed, however X seems to hang when started.

If I switch to the VESA driver (ie run X -configure, then change ast to vesa) it works but is *quite* slow.

I have exactly this motherboard running a FreeBSD 11 kernel (but with FreeBSD 9 user land for reasons) and X works quite well there.

I've tried using syscons instead of vt but it still doesn't work properly.

Does anyone have any suggestions?

Thanks.
