# Sleep
|
||||
# -----
|
||||
#
|
||||
# The system will not resume from sleep properly while on battery power in
|
||||
# either offload mode or sync mode. When it tries to resume, it gets to a
|
||||
# state with a cursor in the top left hand side of the panel, the power LED
|
||||
# goes from flashing to solid, and thereafter cannot be interacted with (even
|
||||
# over SSH) and must be power cycled forcefully. Sometimes it doesn't even
|
||||
# finish going to sleep before this behavior kicks in.
|
||||
#
|
||||
# When on AC, the machine either wakes up from sleep before being asked to
|
||||
# (or maybe never gets to sleep state), or it goes into a sleep state and it
|
||||
# appears consistently resume properly when it does.
|
||||
#
|
||||
# But the machine actually sleeps and resumes reliably when tlp is disabled
|
||||
# fully or partially. Disabling RUNTIME_PM and AHCI_RUNTIME_PM appears to be
|
||||
# enough to allow it to work when tlp is active. I couldn't figure out a
|
||||
# more granular way to get it working, despite trying to do a per-device
|
||||
# binary search via powertop.
|
||||

|
||||

|
||||

||||
# {config, lib, ...}:

#
|
||||
# {
|

|
||||
# # DISK_DEVICES must be specified for AHCI_RUNTIME_PM settings to work right.
|
||||
# DISK_DEVICES = "nvme0n1 nvme1n1 sda sdb";
|
||||
#
|
||||
# # with AHCI_RUNTIME_PM_ON_AC/BAT set to defaults in battery mode, P51
|
||||
# # can't resume from sleep and P50 can't go to sleep.
|

# AHCI_RUNTIME_PM_ON_AC = "on";

# RUNTIME_PM_ON_BAT = "on";
|

# };
|
||||
# };
|
||||
# }
|
||||

|
||||
# I'm thinking this is too aggressive to put into shared config, and folks may
|
||||
# be concerned with the hit on battery life.
|
||||
# See sleep.nix inside this directory for code that allows the system to
|
||||
# sleep properly (out of the box, it will not) at the cost of battery life.
