This problem was fixed by updating the BIOS firmware on the host. 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?
Thanks
