Synergy-core: Switching to login screen causes reconnect

[jasonfisherjlf]

Operating Systems

Server: Windows 10 Version 1709
Client: Windows 10 Version 1709
Client: Ubuntu 18.04

Synergy Version

1.10.0-stable-275cdc1c
synergys 1.10.0, protocol version 1.6

Command Line

N/A - Running from UI

Steps to reproduce bug

On my corporate Windows computer (Jason_email_lappy), it has a CTRL-ALT-DEL command to get to the login. I found the post about using "Pause" instead, and that works. My problem is this:

1. Press "Ctrl-Alt-Pause"
2. Client disconnects and puts my cursor back to my server computer
3. Wait for reconnect
4. Move cursor back to login text box, click, fill out the password and log in
5. Client disconnects again and puts my cursor back to my server computer
6. Wait for reconnect
7. Move cursor back to Jason_email_lappy and FINALLY do whatever it was that I wanted to do in the first place.

Other info

• When did the problem start to occur? I'm a new user, so it has always been doing this...
• Is there a way to work around it? Yes, wait patiently
• Does this bug prevent you from using Synergy entirely? No

Looking at the link below, it says that version 1 isn't supported. If that is the case, why is version 1 listed as "stable", "mature", and "recommended" while version 2 is listed as "beta", "may contain bugs", and requires extra money for Beta access?

Put anything else you can think of here.
This isn't completely blocking me from using Synergy with that computer, but it is very annoying...

As an update to this, I have found that it will also temporarily disconnect whenever Windows asks the user for permissions to perform a task.

@jasonfisherjlf - yes this is a common issue, when UAC shows the modal dialog, and it has been discussed as long as I remember.

IMHO the UAC is designed like this to prevent keylogger to interfere with elevated or sensitive processes.

[jasonfisherjlf]

@xmstspider OK, I figured as much but I was told to log it anyway. It would be really convenient if it didn't disconnect you every time, but it also doesn't surprise me that there isn't anything Synergy can do about Windows' decisions...

Noting that I have the same issue in Win10 20.04 running Synergy 1.10.3 as a client, UAC will kick Synergy but its able to reconnect after a few seconds. Major annoyance for sure but at least it does work albeit with the delay, plus I highly doubt there's nothing Synergy can do about UAC's anti-keylogger design.
