Trying to debug this; not something I use often but would be nice to
figure it out. Under Linux Mint 19.1 (no noises please, it was
convenient for troubleshooting), suspend "just works"- I close the lid,
power light starts blinking off & on, opening lid resumes normally.
Under Qubes 4.0.1, closing the lid acts like above, but resume hangs on
a black screen and the CPU fan slowly spinning up to full speed. Holding
down power button isn't enough to recover- although it will power off,
when I power back on it's still stuck the same way. I have to pull the
battery and power cable to get it to boot. I've tried:
- shutting down sys-net and sys-usb prior to suspend
- shutting down just sys-usb (since only those devices have no-strict-reset)
- adding mem_sleep_default=deep to kernel boot options
- adding mem_sleep_default=shallow to kernel boot options [resulted in
only screen going to sleep but not coming back]
- adding acpi.ec_no_wakeup=1 to kernel boot options
Dmesg says "ACPI: (supports S0 S1 S3 S5)" and /sys/power/mem_sleep says
"s2idle shallow [deep]". The last log lines before it enters suspend are:
dom0 systemd[1]: Starting Suspend...
dom0 systemd-sleep[3586]: Suspending system...
dom0 kernel: PM: suspend entry (deep)
Then nothing until I force a reset.
Any suggestions for a more intelligent way to troubleshoot? Logs or
settings I can look at somewhere in Mint that would give me a hint how
it's managing to successfully resume?
