HDMI port not detected on Ubuntu 18.04
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}
the HDMI port of my lenovo ideapad 500s with Ubuntu 18.04 LTS is not working.
I also executed the xrandr command, but only the primary monitor is detected.
How can I solve my problem?
How can I check that HDMI is not broken?
Thanks in advance.

Concerning your second question about your HDMI cable, please try out, if you have the same problem when starting from a live-cd/usb of ubuntu.

What worked for me (Lenovo thinkpad x1 Carbon, Ubuntu 18.04 LTS), is either switching the display manager back and forth between gdm3 and lightdm
sudo dpkg-reconfigure gdm3
and/or reinstalling lightdm and reconfiguring it again instead of using gdm3
sudo apt-get install --reinstall lightdm ubuntu-desktop

In case you using Nvidia graphics card the nvidia-driver could be a problem.
In my case, I've been using my Lenovo Y530(GTX 1050 ti) with Ubuntu 18.04 with nvidia-driver 415.xx which hasn't been supporting the secondary monitor through HDMI. I've tried in many ways with no luck. I finally upgraded the driver to 418.39 and the secondary monitor began to work! :)
But be careful in case you decided to go and install the driver but are not used to. There are some scenarios which can harm your system which would eventually lead you to format the system.
