Status of Suspend for Librem 5

Purism already started a Burner to upgrade the firmware of modem, i not sure when be ready, but i guess be soon. I hope you fix the modem wake up from suspend mode.

Thanks, the 18sec trick helps a lot. Unfortunately, I might add, as this is saying the phone is getting into that state frequently.
It seems that after each boot, the first suspend allows waking up with a short press, but the second suspend goes into some netherworld, requiring the super long press.
In syslog I can always see the last words PM: suspend entry (deep) followed usually by a block of null bytes indicating some corruption / emergency save(?) before the next boot starts with nothing suspicious looking. Is there a better way of collecting information about the failed wake-up?

Yes, suspend (or actually resume) isn’t stable yet on all devices. I recommend disabling it for now if you experience issues like that, debugging it isn’t exactly straightforward and it’s not some rare issue that needs to be caught in the wild :wink:

Has anyone tried to get an alarm from Clocks to wake up the phone from suspend? rtcwake looks promising, but I have no idea how the interaction between Clocks, auto-suspend and rtcwake could possibly work. Anyone know which backend Clocks uses? Any files that could be inspected during suspend?

I not tested yet the Alarm under suspend mode, but i know that Purism has the Alarm on todo list.
Phosh 17 it featured to work with rtcwake from suspend mode, so i thing Alarm may work already with hwclock.

Tried it. No joy. I ended up waking the phone… :slight_smile:

Thing is, gnome clock has no backend at all. If the clock app quits, no alarm. If the phone is suspended, no alarm. There is an issue filed but no solution yet.

Where are the times of the Commodore 64 with two (2!) hardware alarm-clocks build in? :cry:

Yes indeed, a very interesting device. Thinking of buying one, but:

But some components required to build more Precursor units may not be available for nearly a year, so Huang says the team won’t be able to produce a second batch until late 2022 at the earliest, and possibly early 2023.

Sounds familiar …

Sadly, yes.

I realize it is a security first device and thats fine, but a black and white screen? Its like a 1990’s Blackberry. I don’t mind the keyboard at all, luv Blackberry devices but just a screen with no color and can’t render the web the right way irks me. Is that going to be the real design? I mean all I really want is phone, SMS, MMS, web browsing, and maybe throw in a navigation app and weather app for good measure and I am satisfied as long as it is not a spy device.

It has a completely different level of security, compared to Librem 5:

100% inspectable with standard optical microscope

which is why it’s black and white.

Why is it important to inspect an LCD screen with an optical microscope? What could one find?

Don’t forget, it is intended for different use cases, for other things than standard phone, SMS, MMS etc. And on top of that, as it states on their website: " Precursor is an open hardware development platform".

How is any of this relevant to: Status of Suspend for Librem 5 ?

There is an existing topic on the Precursor: https://forums.puri.sm/t/precursor-secure-fpga-mobile-device-by-bunnie/10788 and it would be best to continue the digression there.

Yeah no make sense :joy:
Well the Precursor(WIPHONE) as far i know the battery life on demand it is 5 hours.

How far is the development of suspend from becoming a reality (enabled by default) ? I ask because the summer approaches fast here and again L5 will be a burning phone.

I try it after OS updates, though no cigar yet, screen for me doesnt wake on push of power button.

@dos excellent insider information about the 18 sec power button press. where can we find this in the firmware source code or component documentation?

long live open hardware!
