I'm having the same experience on my X1 Yoga 1st Gen (i7-6600u).

there are a lot of similar reports here
https://askubuntu.com/questions/1404856/not-waking-up-from-suspend-
ubuntu-22-04

I haven't tested with xorg, but with wayland (both gnome and kde) it
goes to sleep an can't resume.

As an aside: to try and work around the problem (as I was losing data
due to having to power off machine), I enabled hibernation and this
enables me to not lose work, but the hibernation never "completes"
correctly (machine turning off).  the power led starts blinking very
quickly and I can't resume the machine normally.  if I hard power it off
at this point (i.e. hold power button till it turns off) and then power
it back on, the hibernation resume kicks in and I'm back to where I left
off.  I'm left wondering if these behaviors are related at all.

Title:
  suspend problem

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I've installed Ubuntu 22.04 on the ThinkPad E480. Suspend functions ok
  intermittently. Some times it works fine, other times the computer
  does not enter the suspend mode (the screen gets blank, but the
  machine is still running and the ThinPad led is on, and there is no
  way out... no response from keyboard or mouse... the only solution is
  to switch off manually hitting and holding the power button), other
  times the machine does not wakes up from suspension mode.
