Wanted to relate my experience in case this helps others. I have a Supermicro motherboard with an Aspeed built-in video card. I performed a fresh installation using UEFI settings in the system BIOS. The resolution was stuck at 800x600 for an older Acer monitor (capable of 1280x1024). The driver which was automatically selected was SCFB. I researched this in the freeBSD forums and came across a comment that deleting the xorg.conf file would force the system to recreate the xorg.conf file and to put in a separate file of resolution.conf settings in would solve the problem. So:
- use Package Cafe to install the correct driver from x11-drivers/driver-for-your-card. For Aspeed it was identified by searching Freshports and had ast in the title.
- create /usr/local/etc/X11/xorg.conf.d/screen-resolution.conf. I will add a copy of this file to this thread when I get home later today. Twas very basic and had the maximum resolution for the monitor listed: 1280x1024
- rename /usr/local/etc/X11/xorg.conf and xorg.fallback.conf to xorg.conf.etc and xorg.fallback.conf.etc
- log out then log back in. Restart was not necessary.
The lumina display preferences window then had options for all resolutions up to the maximum for the monitor. The appropriate setup was confirmed by examining /var/log/Xorg.0.log.
May be Aspeed video driver installation is not part of the trident installation scripts?
