Comment 23 for bug 1970957

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.
