I am trying to match my display setup to my physical setup. I am on Ubuntu 20.04LTS. My left monitor is in portrait mode, and my right one is in landscape mode.

Here is my current setup. This does not accurately reflect my physical setup, but it is the best i can do for now.

My physical setup looks like this. But when I apply these changes to my settings, my portrait monitor turns off, and then my main landscape monitor stretches out so that I can scroll around the desktop.

I have tried other arrangements within the display settings, and some of them create similar problems. In some cases, my monitors will stack upon themselves and both screens are visible.

  • Having the same issue here. Could you edit your question and add the output of lspci | grep VGA and the output of xrandr. PS! Remember to surround the output by a blank line, and indent the output by four spaces so it shows as "code".

Can confirm.

Lenovo P50 laptop with two external monitors (USB-C & HDMI), one in portrait mode.

Recently upgraded from Ubuntu 18.04 LTS, which did not have this issue, to 20.04 LTS.

The "real estate" of the two landscape monitors bleeds into the right hand monitor and I'm able to "scroll" vertically (which I don't want). Maximizing windows will make the window display on two monitors partly.

Workaround: Change the monitor in portrait mode back to landscape mode. Not what I want but at least it gives me a working setup.

Setup left to right (with portrait mode):

  1. Laptop monitor 1920x1080 (16:9) - landscape
  2. Samsung 34" 3440x1440 (21:9) - landscape - USB-C
  3. Acer 24" 1920x1080 (16:9) - portrait - HDMI

monitor configuration

lspci | grep VGA
01:00.0 VGA compatible controller: NVIDIA Corporation GM107GLM [Quadro M2000M] (rev a2)

Driver recently installed with sudo ubuntu-drivers autoinstall

driver   : nvidia-driver-440 - distro non-free recommended

Recently changed from nvidia-driver-435 which had the same problem.
