Unable to get pfSense to use an external VGA monitor
I'm very new to pfSense, and my current install is only a few days old. It is also running off a laptop (please excuse me for this). Everything was working as I wanted, however today I set up a KVM switch and discovered that when I connect a VGA cable to the laptop, nothing seems to happen. The display reports no signal. I have tried with and without the KVM switch, as well as starting pfSense when the display was connected (rather than connecting it while running), and just to be sure, I booted a Linux distro from a USB stick and the second display worked fine.
I can't really think what relative information I can provide except the output from dmesg | grep VGA:
vgapci0: <vga-compatible display=""> port 0x30c0-0x30c7 mem 0x54180000-0x541fffff,0x40000000-0x4fffffff,0x54000000-0x540fffff irq 16 at device 2.0 on pci0 agp0: <intel pineview="" (m)="" svga="" controller=""> on vgapci0 vgapci1: <vga-compatible display=""> mem 0x54100000-0x5417ffff at device 2.1 on pci0 vga0: <generic isa="" vga=""> at port 0x3c0-0x3df iomem 0xa0000-0xbffff on isa0</generic></vga-compatible></intel></vga-compatible>
Any help would be appreciated!
I'm assuming the built-in laptop display is working fine? If so, VGA is enabled and working. From there, whether or not the laptop actually shows anything on its VGA port is dependent on the laptop itself. Some have function keys you can cycle through to change it from internal display only, internal display and external VGA mirrored, and external VGA only. Most have BIOS settings of some sort that let you control the same settings.
