Hi,
(same new laptop, Lenovo L14 Gen3, new Leap 15.4 install)
I do "systemctl hibernate" as root, and machine recovers instantly. It just flickers the screen to black for an instant, then prompts for user password (XFCE). Tried also Gnome.
...
In BIOS config there is an option that says:
Sleep State: Windows and Linux vs Linux S3 hibernation
I left at default, the first option. Maybe I can try the second option.
Trying [...]
Power led flashes fast for some seconds, then stays on constantly. The red led on the back stays red. The screen stays black. I wait. I think nothing happens.
Machine doesn't react to ping, nor keyboard. I have to press and hold the power button for 4 seconds, then press for power up and fresh full boot.
Ideas?
Bug 1210029 Can't hibernate laptop Lenovo L14 Gen 3 AMD Summary. Machine can hibernate if in UEFI config is set "Sleep State: Linux S3 hibernation", and uses the kernel from Leap 15.5. Initially it appeared that kernel 6.2.8 from "Kernel:stable:Backports" was needed. The issue was confusing because YaST thought that the swap space (25 Gigs) was too small having 32 gigs of ram, and did not insert the "resume=..." entry on the kernel load line. So the machine did hibernate fine, but could never recover but did a fresh boot instead all the time, when using the dedicated Beta (Leap 15.5) test install. Once the entry was written manually the machine booted fine. 15.4 also hibernates fine using the (patched) kernel from 15.5. -- Cheers / Saludos, Carlos E. R. (from 15.4 x86_64 at Telcontar)
