Telegram starting up on its own, unwanted.
 

I've installed Telgram Desktop 1.3.14 on my MX Linux (debian/stretch)
and the program will start itself at odd times. It is not in XFCE autostart after login. The computer will be running for hours and Telegram will simply startup.
I've have not found why it is doing this, there is no browser plugin triggering it, nor is Telegram authorized to use Notifications (XFCE)

Anyone else getting this behaviour from Telegram?

My rkhunter is not working properly so I can't check for rootkits with it.

I don't run telegram any more but have you checked for any telegram files? I wouldn't delete them but you can move them to another archive folder or set the internal switch to not run at start up. Can't remember what that is at the moment.

Telegram was phoning home to it's mother country on my android phone so I go rid of it...

iirc the canonical way would be to copy the .desktop file to ~/.config/autostart, then edit the internal switch (Hidden=True?). that would mask the one in /etc.

yes I have checked
etc/xdg/autostart

Telegram will start on its own after the computer is running, minutes hours, or days without user input

Have you checked your processes to see if Telegram is running a background process?

yes of course

no keyboard shortcuts or bindings as well

OP - I was going to suggest a systemd check but I don't think MX linux uses systemd. I could be wrong though. Personally I don't like telegram once I found out it is constantly phoning home to the country in which it was originally written. To me that's a little scary. It probably isn't spyware per se, but the phone home traffic was not relevant to the app so this was alarming to me.

Something has to be starting it - Linux apps can't just start on their own. Apps start either as a daemon system wide (systemd these days), or via a .desktop startup file in /etc/xdg/autostart, or ~/.config/autostart.
