External display not detected by MATE Display config panel

Hi friends,

I am trying to connect a BenQ PD2700Q monitor via HDMI or Displayport to a GhostBSD installation on a Lenovo Thinkpad X230.

For some reason, the external display is not detected by MATE's Display configuration panel.

There was another forum member having some issues with connecting an external monitor last year, and as one of the suggestions was to install the full Xorg server, I did a

Code: Select all

sudo pkg install xorg-server 

but was told by the system that "The most recent versions of packages are already installed".

Is there anything else I might try? Thanks.

Hi friends
I recommend checking the system logs “/var/log/Xorg.0.log” and using “dmesg” to look for any error messages
Let us know if it helped

I've tried looking at /var/log/Xorg.0.log with dmesg | less but am not sure what sort of error messages I should look for. I did a search for "HDMI" in the system log and there was

pcm1: <Intel Panther Point (HDMI/DP 8ch)> at nid 5 on hdaa1
pcm2: <Intel Panther Point (HDMI/DP 8ch)> at nid 6 on hdaa1
pcm3: <Intel Panther Point (HDMI/DP 8ch)> at nid 7 on hdaa1

But I guess this is not it. I will try to connect the Benq display to the laptop again, and then look at the log files immediately afterwards to see whether I can see something like an error message then...
