Rebooting on Standby

[Rellik]

Has anyone seen this before? The first time my machine goes to sleep, everything works correctly. If it wakes up then goes to sleep again, it actually does a reboot. I didn't see anything in the logs but I can post if needed. I'm dual boot with windows 10 and that goes to sleep without any problems as many times as I want. Thanks for any help.

Version of Kubuntu you are running? PC specs?

If you could post the results of

inxi -Fxz

into a CODE box (the # button in the reply window) that would be useful.

Thanks for the response. Here's the output of the inxi -Fxz

I'm not an LVM expert, but I believe that's what you are using with your drive.

Enter this and post the results back in a CODE box:

lsblk --output NAME,KNAME,TYPE,SIZE,MOUNTPOINT

[Rellik]

Yes, I chose LVM when I installed. I don't mind reinstalling without it if that will help.
