Or underclocking...to get longer lasting battery or device. Most of time Pinephone uses only 1/20 of it's CPU.
Coolest way should be desktop widget that has 3 sliders like this:

CPU speed 125 Mhz --O-----O-------------- 1.5 Ghz
Battery life 1 min --O-----------------O-- 96 hours
Device life brake -------------O-------O- 100 years

And buttons (Use new settings) (Revert old setting)
And when you move one of sliders it moves two another automatically, by estimation calculation.
And it gives warning "Are you sure" if you try brake device.
And it automatically set between underclocking and overclocking by cpu load and how much battery is left of those lowest and highest setting.

This looks like its has come a long way, I really want to try it! Its there some idiots guide how to install it onto a spare N900 I have. ideally a file with hyperlinks to everything needed with explicit step by step instructions?

Maybe not total idiot proof but I'm an idiot and have managed to follow this:

https://leste.maemo.org/Nokia_N900

Scroll down for installation guide. Download the latest image from here:

I used Balena Etcher to get image to sdcard which is easiest way:


https://etcher.balena.io/


I followed the guide for working Fremantle. I will not go through flashing that.If you need guide for that, because maemo.wiki is down you find guide from here:


https://web.archive.org/web/20230125...g_the_firmware



After getting image on sdcard and you have Fremantle side ready, shutdown N900, boot (keep the lid/keyboard open and press the power button), with arrow key move on the menu that will appear to boot Maemo Leste.

Let it boot and even after you get to desktop give it some time.


Expand the space on your sdcard as in guide.Open xterm and:


cd /etc
sudo ./ expandcard.sh

I think after it has finished you could restart the phone and only after new boot start to do more.

Connect to your wifi.

Enable devel repository:
Open xterm.


Sudo apt update
Sudo apt-get install leafpad

Then:
sudo leafpad /etc/apt/sources.list

Add the devel repo on list:

deb https://maedevu.maemo.org/leste chimaera-devel main contrib non-free n900

Click menu/top bar and click save and close.

Sudo apt update
Sudo apt upgrade

Then to overclock install cpufrequtils:

Sudo apt update

Sudo apt-get install cpufrequtils

Then follow the guide on Leste wiki for overclocking. The path given on wiki may not be the same so you may need to find it by cd to /sys/devices/system/cpu/cpufreq/. I could not at first find the boost. But it was before installing cpufrequtils. Maybe now I could.

Enable swap as is described on instructions.

If someone sees I have given stupid instructions, please correct and give better. These are just to get started and to get the device overclocked and swap enabled so it will perform better while doing other configs.

I should go through the installation guide as for total noob eith linux and with all steps given for script kiddies like me.

By the way, swap is already activated (no additional steps needed).
Overclock is not absolutely necessary anymore, it works fine with 250-600 MHz (thanks to freemangordon work). So you can try without first.

Boot time is still a bit long, so be patient if the device is a bit unresponsive for let's say 2min, then it is ok and quite fast with a good SDcard and devel upgrade.
The two really useful remaining tweaks from the wiki are the '.nomedia' file in /home and the lower radius values in transitions.ini file

(The N900 wiki is not totally up to date, it needs to be modified a bit, i'll have a look).

Thanks for update and corrections. Just seems odd that 250 600 would be enough cause it wasn't even on Fremantle. But I will try. I couldn't change the keyboard lauout on settings on tye image before last one. It crashed and didn't open on settings at all.

Maemish: i recommend you to try 500-600: that's what i'm using for a while,
that's very smooth with a custom transitions.ini file, no tracker in home and devel upgrade, that's it
I only use 805MHz for specific multitasking or for pcsx_rearmed sometimes.

And indeed, Hildon-Desktop with Leste is now faster than Fremantle with stock freqs at least, with a good SDcard.

Maybe we should start a new thread for N900 customization and optimization ?

Yes! Share your custom transitions.ini cause now when wiki is down it is even harder to leran tweaking it. I tried some tweaks but then just out of curiosity did my usual thing: enable many repos and do upgrade with force aptitude and see what happens. It normaly never ends up well.

Boost file it in there after enable and update devel repos.

I changed the boost file from 0 to 1 but after reboot my nokia n900 it freeze forever, i not sure how revert it without reburning leste


EDIT: well after wait till 3 minutes after booting my nokia n900 got unfreeze. = )

Huge thanks for Arno_11 for all the manpower for nokia n900.
