Ubuntu Server 18.04 cannot switch to external display [closed]












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

  • 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?

  • That's a good thought - it should be VGA->HDMI, but I'll double check. I've tried it on another device and it didn't work there either, so it's either faulty or HDMI->VGA.
