Disabling display auto detection on Ubuntu 20.04

mk flag

I am working on a system supporting multiple displays connected to an Nvidia display card (using DP).

Whenever I connect/disconnect a display all the remaining connected displays turn black for a couple of seconds until the displays are rearranged and then the image comes back.

Is it possible to avoid this auto detection by the window/desktop manager? I want to avoid this short period of not showing an image on the monitors that were not changed. The ideal solution for me would be to get notified when such a change in connected displays has happened but to do the configuration and placement myself.

I have tried to disable xrandr without any effect. Also tried to set the "UseHotplugEvents" to false in the xorg.conf without any effect.

This is similar to How to disable auto display detection on Ubuntu 19.10 but there is no answer there.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
