I'm using HP Elitebook 1040 x360 G8 with Ubuntu 22.04 LTS and found out that system is not waking up after being suspended although power is definitely switched on and fans start spinning - screen stays turned off and laptop does not react on any keyboard combinations.

These are the last messages in journalctl output:

июн 21 20:39:04 ivan-HP-EliteBook-x360-1040-G8-Notebook-PC kernel: PM: suspend entry (s2idle)

Yeah, I've found out that issues with suspend mode are quite common for HP laptops for almost 2-3 years already. But still wondering if there will be some solution one day. Or maybe somebody already has a workaround for such cases?

I recently got a new HP Probook G11 with Ryzen 5 7535U with Radeon R680m integrated graphics. I had the same problem of the screen not turning back on after suspend or sleep. I found a solution by setting

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash processor.max_cstate=1 idle=nomwait amdgpu.aspm=0"

in the grub from \etc\default\grub. The screen freezing issue has disappeared for now :)
