Ubuntu Server 18.04 cannot switch to external display












1














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?



xrandr output:



Can't open display


lshw -c video output:

I'm pretty new to CLI on Ubuntu, so just let me know if there is other relevant information I should post

  • 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?
