UI and multiple displays

@karl_jones Hi,
Do you know when Display.RelativeMouseAt will be supported on Linux?

 

I am using the unity version 2019.2.3f1 for Linux.
I have 4 monitors (display 1 to 4) displaying fine the UI in each one. But as it is described here, only the clicks in the main monitor are working well, all others are redirected to the main monitor.
Yes, I tested it and does not work. The next code always returns zero in x, y & z.
Display.RelativeMouseAt(Input.mousePosition);
What could be the problem?

 

In a player build.

 

Hi @karl_jones,
I am compiling and running the player build
Do you have any hint?
Do I need to configure something else in the settings to make it work in the player build?

 

@karl_jones, any news about this issue on Linux (click on multiple displays)?

 

Officially Display.RelativeMouseAt is still not working in Linux for the new versions of Unity. It only works for Windows until Unity 2019.2 (https://docs.unity3d.com/ScriptReference/Display.RelativeMouseAt.html) and it works only for Windows & MacOS with the new Unity 2019.3 & 2020.1 (https://docs.unity3d.com/2020.1/Documentation/ScriptReference/Display.RelativeMouseAt.html)
So, last week, I solved the issue in Linux executing, since a C# script, a Linux command (using xinput and several parameters) to get the mouse coordinates in the whole screen (that includes all the monitors). Maybe you can add this type of solution to the Linux version of Unity.

 

Has this issue been resolved in the latest version ?

 

@karl_jones Hi I am creating a car simulator where I required to display the scene over 3 monitors, now each monitor resolution is 1920 x 1080 so i fixed the resolution from script to 5760 x 1080, which is 3x of 1920 and set the full screen to false and window type is maximized window, now when I launch the exe, the game is presenting fine on all 3 screens but the Ui only working on left monitor only but i need Ui to work on all 3 screens. Please help me on this...

 

no its not touch screen

 

yes the mouse input is not working and the setup is extended, also my canvas of Ui render mode is screen overlay and reference resolution is 1920 x 1080

 

Hi, guys! I am working on an application that needs 2 displays. In Windows build everything is ok, but in Linux, when the 2 displays have different resolutions, the UI events only happen in one display and some actions reflect on the second display. I am using the version 2020.3.16f1. Is there any bug fix for that? If not, how could I fix? Thank you! @karl_jones

 

Hi, @karl_jones, can you help me, please?

 

Thanks for the reply, @karl_jones ! But like I said before, the Windows build is ok, but for Linux when the 2 displays have different resolutions, the mouse events don't work on the second display. Is there any fix for Linux platform?

 

Using New Input System, UI doesn't recognize any input (both mouse or touch) on a second display. Instead, mouse clicks on the second display will trigger a click on the main display at the same position. Any help would be appreciated.

 

Wow, it boggles my mind that 6.5 years later this is still an unfixed issue not only in the now legacy input system, but also in the new one. This is just awful.

 

I'm with you trying to figure this out too. Ugggg... how is this even a thing at this point?

 

Having a similar issue.

We work with prototypes interactives for museums. In our test lab we might have 3 or more monitors hooked up to a computer and need to remap displays. We move these monitors around a LOT, so we like to change the target display in app rather than in build and rebuild over and over.

The issue is, that when we change display the second display is not accepting input. We're instead seeing the issue that @akshays2 describes where all input is sent to the first monitor and its UI. This is a huge slowdown for our workflow, is there any progress on the issue of second display input for UI?

 

Any news on this one ? Still having this problem trying to setup multiple touch displays with multi touch. Multiple touch events work fine on the first display but on the second display touches are handled like mouse clicks. I Checked the input devices and it seems that only one touch device is registered as u said.
