MeshAgent: Manjaro multple monitors not showing screen selector

[CircusMusic]

I posted in the subreddit and was told to report this as a bug. I have a workstation that has 4 monitors running Manjaro, when I connect to the desktop it shows all 4 screens at once with no option to select which screen I want to view and is obviously difficult to use because the screens are so tiny. When that machine was a windows box I was able to select what screen I wanted to see and I could actually read what was on the screen.

Meshcentral version: 0.8.92 Agent running on Manjaro: Linux 64bit 2021-03-25, 5:25:02 p.m.

Thanks for porting this and the details. This is probably from this Reddit Post.

I'm having the same issue on Ubuntu 20.04 LTS, I have 4 screens which shows all at the same time.

What server version are you currently running??

[krayon007]

I'm able to reproduce this on one of my ubuntu machines, so I'll look into it...

[krayon007]

Can you go to the terminal tab, right click on connect, and select "login shell", and login to the linux machine (or open a terminal on the actual linux machine)

and navigate to where the agent is installed, and run the following command: ./meshagent -exec "require('monitor-info').getInfo().then(function (m) { console.log(JSON.stringify(m, null, 1));process.exit(); }, console.log);"

On my machine, X is reporting that I only have one display, and is showing its resolution as being the combined resolution.

Hi -

I have the same issue on Windows. Is this issue fixed or is there a workaround so I can "remote" into only one of the multiple monitors connected to the remote PC?

[formanjackj]

I am having the same problem on a Windows environment, however, in my case, the problem was related to which browser I am using. (I think)

My Mesh server is 1.0.0 Chrome is Version 104.0.5112.102 (Official Build) (64-bit) Works fine Firefox is Version 103.0.2 (32-bit) NOT Working Microsoft Edge Version 104.0.1293.54 (Official build) (64-bit) NOT Working
