Ubuntu Server 18.04 cannot switch to external display
I have an old Toshiba laptop from 2008 on which I have installed ubuntu server 18.04. The built in laptop screen is cracked, so I had it connected to a VGA monitor for a while and it worked fine. I wanted to connect it to my TV, so I bought a VGA to HDMI display converter, but when I use that converter, the TV doesn't receive any input. VGA to HDMI shouldn't require any additional drivers, so does anyone know what could be going on?

Sounds like the adapter is faulty. Did you try it on a different device? Are you sure it is a VGA->HDMI converter and not HDMI->VGA?
