Probably this question has been answered somewhere, but I have been looking and most of the problems were a little different than mine.

As the title explains I have the following problem:
I have a dell Inspiron 15 with a gtx 1050ti. I installed a fresh install of ubuntu 18.04. I then wanted to run a 2. monitor via HDMI, but when I tried plugging it in, I only got a black screen, so the monitor has a signal, but the screen is black. My xrandr:

My driver settings


My graphic settings

Then also there were some times, where I got still pictures on the second screen which look similar to this, I couldn't find a pattern, sometimes if I changed the settings, it would look like that, sometimes not:
Weird screen



What I have already tries:

  • Configuring the display via xrandr, changed nothing
  • I have tried reinstalling the nvidia driver


Also I wanted to add, that this monitor is 21:9, I don't know if there are some known issues for 21:9 monitors or something. Also the monitor works perfectly fine in Windows.
Hoping to get this fixed soon, thanks for your help in advance!!

I had same problem, I figured out, sudo prime-select nvidia,then check by prime-select query,and if it return nvidia, reboot. After that check settings->details for which graphics card you are using . That solved my problem.
