When I started my computer this morning, all of a sudden the system wasn't detecting my second monitor, which was working just fine until last night... I'm running Ubuntu 16.0.4 LTS.

Under System Settings > Displays, nothing happens when I click on Detect Displays.

Can anyone give me some advice on where begin troubleshooting this please?

UPDATE

In response to someone's questions asking for details, this is the output of running the xrandr -q command.

  • does xrandr -q show the 2nd display as connected to system – ptetteh227 Apr 15 '18 at 17:15
  • hello. I have updated my question with the output of that command... It seems like it doesn't display it as connected. – jsdev17 Apr 16 '18 at 11:13
  • perhaps a hardware or cable connection issue. Also upgrading ubuntu kernels could cause the problem (https://askubuntu.com/questions/971788/secondary-monitor-not-being-detected-anymore-after-kernel-upgrade) – ptetteh227 Apr 16 '18 at 12:42
