Hullo,


Struggling a bit with my first FreeBSD install.

Mouse and keyboard are detected without any trouble, but the monitor, a 
Dahua LM24-S420, is not giving a lot of joy. This monitor usually works 
at 1920x1080 @ 60Hz, but is not delivering anything like that now. 
Current spec is 1024x768.

xrandr states:

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 1024 x 768, maximum 1024 x 768
default connected primary 1024x768+0+0 0mm x 0mm
    1024x768       0.00*
    800x600        0.00
    848x480        0.00
    640x480        0.00


Showing, from what I can see, that no connection is recognised.

So, there's nothing I can configure.

I've tried placing a file in /usr/local/etc/X11/xorg.conf.d/ 
(screen-resolution.conf) which achieves nothing

The latest move is to create /root/xorg.conf.new, which advises, when 
tested:


(EE)
Fatal server error:
(EE) no screens found(EE)
(EE)


If there was an equivalent to lshw that would give me information on the 
connection point, that might help, but that doesn't appear to be 
available as lshw.

Can anybody give me any advice on where to go from here?

Thanks for any trouble.


David
