Problem with suspend in 22.04 jammy on new build - Gigabyte B550 Vision DP

[xoorox2]

I had a problem with not being able to suspend - the machine would suspend (you'd hear the click as the power supply turned off) and then immediately wake. I've got a fix now but I thought I'd share in case it's helpful to someone else.

I first did a little digging... tried the tweaks lid setting (even though it's a desktop).
In the end this post in the linuxmint forum pushed me in the right direction.

In my case though, it wasn't a bluetooth mouse causing the problem. I methodically ruled out external devices (usb audio interface, a midi interface, wireless dongle for mouse/keyboard) just by unplugging them.

Using cat /proc/bus/input/devices to look at my list of input devices gave me

This I compare with the output of cat /proc/acpi/wakeup

cat /proc/acpi/wakeup

PT29      S4    *enabled   pci:0000:03:09.0

To toggle on and off a line, I would use (for example) echo PTXH | sudo tee /proc/acpi/wakeup to stop the mouse/keyboard from being able to wake the machine up. But in my case it wasn't this. (I re-enabled as I'd like to be able to wake the machine using the mouse/keyboard).

I didn't find a culprit in the list of input devices. I tried GPP8 as this appeared to cover off everything related to my monitor. In the end I looked at the output of lspci as before I tried disabling the other items in the list, I wanted to know what they were.
In the end it was disabling GPP0 that fixed things for me. In

lspci

So I don't know quite what's going on here, but it does seem to have solved my problem for the time being.

So I've marked this unsolved again - when you restart the setting is lost. I can have the command run at startup... but surely there's a better fix out there, anyone?

[xoorox2]

For the record, I successfully followed these instructions here - https://askubuntu.com/questions/1146...gs-permanently to set up a script to create a service to run a script to disable chosen devices (if they are enabled).

You are my hero! Thank you! Disabling GPP0 fix this for me. I have the same Gigabyte B550 Vision DP and it was failing to suspend. It would crash after I tried to suspend with the same power click after it appeared to suspend just like you said. The motherboard post code / Debug LED code showed 21, and on the manual the description for those are under "Reserved.". Doing sudo sh -c "echo GPP0 > /proc/acpi/wakeup", to switch GPP0 from *enabled to *disabled state did the trick!
