Laptop won't resume after going into suspension/lid close

Distribution

EndeavourOS

Package version

6.4.10

Graphics hardware in use

Intel Iris Xe TGL-GT2

Frequency

Always

Bug description

When suspend mode is activated via lid close or after a set time, the laptop becomes frozen with either a blank screen or whatever was on the screen at the time of last use, typically when the lid is closed.

No keys or mouse will work. Only powering down using the power button to then power back on.

I am using the latest release of the Linux hardened kernel, however this happens when using the latest zen or standard kernel as well.

Happy to give any more information needed.

Thanks.

Steps to reproduce

You can reproduce this by closing the lid of the laptop if you have suspend mode set to activate upon lid close, or allowing the set time of no use to allow the laptop to enter suspend mode by itself.

Expected behavior

I expect the laptop to suspend, and upon key press or mouse movement get prompted to log back into my session.

Additional information

No response

The report identifies suspend and lid-close behavior on a Dell Inspiron 15 5510 running Cinnamon, but names no repository file, test, or entry point. Start by locating Cinnamon's suspend and lid-close handling, then reproduce the failure and determine which component owns the resume behavior before defining a testable fix.
