I believe I have sleep configured according to Support for the S0ix sleep state · Issue #6411 · QubesOS/qubes-issues · GitHub.
I can suspend, and wake from suspend
However /sys/kernel/debug/pmc_core/substate_residencies always says 0.
Substate Residency
S0i2.0 0
qvm-features dom0 suspend-dom0-s0ix is enabled
/sys/power/mem_sleep
[s2idle]
/sys/kernel/debug/pmc_core/substate_residencies shows several items without a Yes under Live Status. Is that the reason substate_residencies always says 0?
I only have one USB controller in sys-usb. (No Thunderbolt devices).
I regularly use a Dell WD19 dock for connecting an extra display, mouse, and keyboard.
S3 is not supported in BIOS.
I’m running Qubes 4.2.3 with testing updates.
How can I best troubleshoot this so that sleep will fully work?
Thanks,
