cm-rgb-monitor stops running after sleep mode

As said in the headline, after waking up my computer from suspend cm-rgb-monitor does not show anything anymore.

Steps to reproduce:

• Start cm-rgb-monitor
• suspend computer to ram
• wake computer up again –> cm-rgb-monitor stops showing CPU load/temperature

Simple mitigation like a try/except in the eternal while loop don not work, neither does a while/True around the monitor() function.

if __name__ == '__main__':
    while True:
        try:
            monitor()
        except Exception as e:
            print(e)

Additional information:

• cm-rgb 0.1.0
• OS Kubuntu 20.04
• Python 3.8

Yes, that worked - but I had to remove the BindsTo and After lines and it is in /usr/local/bin for me.

I’d prefer if it was possible with the autostart folder and now cm-rgb-monitor runs as a system service (maybe I’ll try as a user systemd service later), but as long as my CPU lights up everything’s good^^

I still get the same error message in journalctl I posted above, but it automatically restarts.

Yes, the service starts now and from limited testing continues working after resume from suspend.
