Computer Refuses to Sleep

OS: Ubuntu 22.10 Graphics: Nvidia GeForce GTX1060

uname -a

After reading through all possible solutions:

• Ubuntu 18.04.2 immediately wakes up from suspend
• Ubuntu wakes up after few seconds of sleep
• laptop fails to suspend or hibernate (wakes up after 2-5 seconds without user interaction)
• How do I prevent immediate wake up from suspend and/or hibernation?

My computer still wakes up immediately after being suspended.

I tried disabling EHC1, EHC2, XHC but it didn't do much so I left it as enabled. Below is just to show what else is waking up my PC.

cat /proc/acpi/wakeup                                                                     INT ✘

I checked for any USB devices that wake up my computer but they're all disabled.

cat /sys/bus/usb/devices/usb*/power/wakeup

I also enabled nvidia-suspend.service, nvidia-resume.service, and nvidia-hibernate.service using systemctl but it still came on after suspension.

I checked every line in /var/log/syslog but I couldn't find what triggered it. I can see the computer went into sleep mode. All CPU Cores went offline and all of the sudden, ACPI PM started Low-Level Resume. Any idea where I should look to fix this issue? I didn't check syslog in Fedora but the same behavior also happened on the same machine before I switched to Ubuntu. This leads me to suspect there's a single common problem, Nvidia Graphic Card driver. Any help is much appreciated.

I had a very similar problem for a lot of time. Apparently in my case I had conflicting configuration files.

When doing:

dpkg -l | grep -i nvidia

I could see a list of packages that I was not using marked with rc in the first column.

After removing them with the following command the computer started to suspend correctly:

sudo apt-get purge $(dpkg -l | awk '/^rc/ { print $2 }')

I hope it helps.
