# Ubuntu – Clicking on the system monitor button does not work anymore from one day to the next (Ubuntu 18.04)

guisoftware installationsoftware-uninstallsystem-monitor

My taskbar on the left side displays the system monitor symbol. By just clicking on it, I was able to open it. But suddenly, it stopped working. I clicked on it and Ubuntu seemed to load and open the process but quitted doing so after a while – and acted as if I have never clicked on that button. Yesterday, everything was still fine. Today, Ubuntu is acting that weird.

• It does this sometimes if you keep your system running for days without restart.

to solve this whenever it happens:

Run in the terminal

killall gnome-system-mo


then

gnome-system-monitor


it should work fine after this.
