I have since successfully installed the mate desktop, upon which I am composing this message. I have a small remaining difficulty respecting the display. I am using a HDMI interface with an ASUS VP239 1920x1080 monitor. However, FreeBSD / Mate does not recognise this monitor nor can I discover how to manually set the resolution from inside mate. System > Preferences > Hardware > Displays Shows: Monitor Unknown, Resolution 1280 x 1024 (which is the maximum value in the scroll bar), Refresh rate 0 (and cannot be altered), Rotation Normal. Detect monitors has no apparent effect. What is the procedure to update FreeBSD to handle the monitor that I have?
