I recently switched into Ubuntu 18.04 from Windows 10 on my laptop. My goal is to connect additional monitor to my laptop. I had been using my second monitor when I was using Windows 10, so I know this is not a hardware problem. I know there are plenty of questions posted in this forum, but none was helpful.
Here is my xrandr output
Screen 0: minimum 320 X 200, current 3200 X 1800, maximum 8192 X 8192
eDP-1 connected primary 3200X1800+0_0 (normal left inverted right x axis y axis) 293mm X 165mm
DP-1 disconnected (normal left inverted right x axis y axis)
Graphic Card: Intel HD Graphics 5500
On activities > settings > displays, there is no "detect display" feature or "configuration" feature. I can only see resolution, scale, refresh rate settings under "Built-in display".
I wonder what causes this problem.
- Is this graphic card driver problem? If this is the case, how do I update Intel graphic card driver on Linux? I think it is up-to-date honestly.
- HDMI port is not visible in my xrandr output unlike many others. How can I add one, or can I simply use DP-1?
- If my system does not automatically detect the second monitor, should I statically edit xorg.conf?
