Status of Suspend for Librem 5

prog-amateur · October 28, 2022, 9:58pm

So another test after updating u-boot and PureOS, I confirm that the phone can’t be awaken by SMS or phone call while on Suspend to RAM.

What is strange: if the L5 is in STR mode, and I send a text message or make a call, the L5 screen wakes up but there is no notification of received text messages or missed calls, and the 4G signal bars are totally absent from the notification bar.

So the L5 can detect an activity but cannot display any notification and cannot ring, only the screen turns on. What could cause this issue ?

Thank you.

I have that same behavior with the following notification:
Automatic suspend

Computer will suspend very soon because of inactivity.

It even starts to blink blue/pink just before going to sleep.
I get caught by that many times which prevented the phone to actually go to sleep

A number of messages in this thread had me confused or actively negated each other, but at the time of this writing, on a librem 5 running PureOS byzantium, this is what you should do (and this should be somehow clearly communicated to all librem 5 owners, I think):

In a terminal, run cat /proc/cmdline to find the current version of the uboot bootloader on your device. If the version number starts with 2019, continue to the next step; if it starts with 2022, you don’t have to update.
Run sudo apt update && sudo apt install u-boot-librem5 to install a package that can update the bootloader.
Run sudo u-boot-install-librem5 /dev/mmcblk0 to update the bootloader.
Reboot the phone via the GUI or run sudo reboot to start the phone using the newly updated bootloader.

No need for manual deb package downloads anymore!

Well your solutions was only possible recently, no before, but also ur solutions can not for testing new things of Das-.
Thank for updating this post.

Is there a special repo I need to add for that? On my phone, I get Unable to locate package u-boot-librem5.

samuelnorbury · November 14, 2022, 9:49am

Indeed, I was mistaken. Here’s a one-liner to install the latest version (replaces step 2):

wget https://source.puri.sm/Librem5/uboot-imx/-/jobs/399069/artifacts/raw/debian/output/u-boot-librem5_2022.10-librem5.1_arm64.deb && sudo apt install ./u-boot-librem5_2022.10-librem5.1_arm64.deb

Is there a reason this is not included in the regular update? Is this safe to run?

ppisa · November 20, 2022, 12:00am

I have tried the U-boot update. My actual versions
u_boot_version 2022.10-gc4960dade2
Linux pureos 6.0.0-1-librem5 #1 SMP PREEMPT Mon Nov 7 21:26:38 UTC 2022 aarch64 GNU/Linux
Suspend and wake-ups by button looks working well, congratulation this is big enhancement. But when I use Mobile Settings Librem 5 suspend now or I manage suspend by setting and wait from the Setting Power setup then when I call, device does not wake up. Is is possible that it is again problem of older HW revision as in the GPS case?

Captain_Morgan · November 20, 2022, 2:03am

same here btw auto suspend and wake is fine but manual suspend through mobile setting fails to wake, maybe file a mobile settings bug?

zks1 · November 20, 2022, 10:01pm

I also updated the uboot file. And similarly to others, I’m seeing improvements on the wake from suspend. Not a complete fix.

But, now, i’m noticing that if I’m in convergence mode, the phone charge rate is incredibly slow?! I’m using the same usb-pd that came with the phone to power the dock (the one purism sells for the phone). Before I updated the uboot, I didn’t notice this change. If I don’t use the dock, the same usb-pd cable charges the phone at the normal rate.

Anyone else experience this?

ppisa · November 21, 2022, 11:55pm

I’m using the same usb-pd that came with the phone to power the dock

I have similar experience but even before U-boot update. I have looked at negotiated parameters before, but I am not sure what has been there already.

Anyway, actual output of
cat /sys/bus/i2c/drivers/tps6598x/0-003f/typec/port0/power_operation_mode
is 3.0A
cat /sys/bus/i2c/drivers/tps6598x/0-003f/typec/port0/power_role
is source [sink]
so it looks good and cannot be probably better even with original adapter. Higher voltages are not enabled as said in another discussion etc… On the other hand even dock draw some power so s charging can be slower due to that.

What you want to look at is /sys/bus/i2c/drivers/tps6598x/0-003f/power_supply/tps6598x-source-psy-0-003f/current_max

or even /sys/class/power_supply/tps6598x-source-psy-0-003f/uevent - easier to remember with some help of tab-completion

ppisa · November 22, 2022, 9:09am

Thanks for clarification

This is only 1500000 on Vention Type-C (USB-C) to HDMI / 3x USB3.0 / RJ45 / SD / TF / 3.5mm / PD 0.15M Gray.

When power adapter connected directly, then it is 3000000. The question is, if the limit is given by Librem 5 or the dock has its power pass-through limit or dock knows that it has some own consumption and lowers rating to not exceed power adapter capability. I am not sure if it can be checked if the dock internally negotiated higher voltage with adapter. Purism adapter provides 18 W only at 12 and 9 VDC. On the other hand dock does not include stepdown converter to 5 VDC (only acceptable for Librem 5 for now) so probably choice of 5 VDC, 3A (15W) is only option. Question is, if it can declare for example 2.0 A to pass-trough a and use 5 W for itself. Gigabit ETHERNET is power hungry. HDMI should not be so big problem.

dos · November 22, 2022, 9:36am

It’s what the dock offers to the phone at 5V.

ppisa · November 22, 2022, 9:48am

Yes, I understand, but question is why the dock it lowers rating from 3A @ 5V to 1.5 A @ 5V. 7.5 W is a lot but on the other hand if it should have reserve to drive up to three own USB ports and ETHERNET, than it is in the fact right decision… But I have ports empty by now…

ppisa · November 22, 2022, 10:00am

I have tried experiment to power dock from 112 W power supply and Librem negotiates 1.5 A @ 5 V only as well. When I try to use I-TEC USB-C Metal Low Profile 4K Triple Display, Power Delivery 85W docking station with its its 112 W power supply, I gen only 0.5 A on Librem 5 side. When I use the same dock with Librem 5 adapter, I get again only 0.5 A. But this big dock is generally designed for big laptops, where it is able to power my DELL Latitude, so may it be on 5 V it uses only some basic minimal pass-through.

Quarnero · November 22, 2022, 4:50pm

You might want to do few tests with providing power to Venton or other docking station from some power bank (preferably from USB-A port, especially if used power bank is not of 5V only type) and get negotiated 2000000 there (10W).

EDIT: As well, the same amount of 10W from some docking station we have reported here:

carlosgonz · November 30, 2022, 1:17am

I tested today the suspend so the autosuspend or manualsuspend or appsuspend always wake up my Librem 5 all time. As i still not using L5 as a daily driver so the test was without modem ON.

prog-amateur · December 10, 2022, 1:08am

Would you have a clear visibility (roadmap) on this subject please?

This is not a troll, but honestly, knowing that the Librem 5 is sold to companies, how can we convince them to buy a phone that can’t come out of standby?

Thanks for your feedback.

Loak · December 10, 2022, 8:08am

Hi,
What do you mean by “appsuspend” ?
How do you enable this ?
