I am running xubuntu 14.04.03 (ubuntu + xfce4) and use the gnome-system-monitor to check the processor and memory load, as well as get an overview of the running processes.

I struggle to open multiple instances of that tool. Simple calling gnome-system-monitor from different terminal windows does not help. It also does not have any sort of "new instance" options. And according to this question -- Run true multiple process instances of gnome-terminal -- it is a general problem with gnome applications. That answer provides a solution that should assign an --app-id to the gnome-terminal. That does not seem to work with the gnome-system-monitor.

I am wondering if there is an option to run any application in a new instance regardless of its options. I would want the system monitor to be assigned to a hotkey and pop-up on the current workspace in a new instance. Is there a command for that? Like exec gnome-system-monitor --new-instance.

Thank you!

  • There's no app-id in this case... You'll have to wait for gnome-system-monitor to be fully ported to gapplication and hope that one of the actions will be new-window. – don_crissti Jan 15 '16 at 14:05

I know this answer is slow but I had the same problem and solved it this way:

  1. Open system monitor using whatever method (gnome-system-monitor).

  2. Open the next instance with sudo (sudo gnome-system-monitor).

This only gives you two instances but for me that is enough. I automated it with a script like this:


gnome-system-monitor &
printf '<PASSWORD>\n' | sudo -S gnome-system-monitor

It isn't ideal that the password is in the file but at least you can make sure that no other users on the system can read the file.

  • Ha! That's a good one – Ufos Jan 6 '17 at 10:06
