It doesn't look like you have bq27x00_battery module loaded, OR you're looking into wrong sysfs node (rx51-battery vs bq27200-0 one).

Should I? :confused:

Both, my regular device and the testing device (runing latest CSSU thumb) use rx51_battery.

btw:
The new lxsession binary is available in Sid now and it actually shuts down and reboots.

What do you mean by broke the N900 power button functionality? When I press power button on my N900 with E19 + systemd, it's offer me to poweroff. E19 input settings recognize N900 power button as XF86PowerOff, and you can set action on this key at input settings as well as at ACPI settings too.

Sorry, I somehow missed your post before. When I tested the power button with systemd it was without X11 and it didn't work. Normally acpid will detect a power button press and run the action configured in /etc/acpi/events/powerbtn-acpi-support. I'm guessing that systemd was trying to be too clever by intercepting the button press. As soon as I installed sysvinit-core it started working again.

For comparison my netbook:

Code:

$ cat /sys/class/power_supply/BAT0/uevent 

POWER_SUPPLY_NAME=BAT0

POWER_SUPPLY_STATUS=Discharging

POWER_SUPPLY_PRESENT=1

POWER_SUPPLY_TECHNOLOGY=Li-ion

POWER_SUPPLY_CYCLE_COUNT=0

POWER_SUPPLY_VOLTAGE_MIN_DESIGN=8400000

POWER_SUPPLY_VOLTAGE_NOW=7500000

POWER_SUPPLY_CURRENT_NOW=1192000

POWER_SUPPLY_CHARGE_FULL_DESIGN=6580000

POWER_SUPPLY_CHARGE_FULL=4194000

POWER_SUPPLY_CHARGE_NOW=3337000

POWER_SUPPLY_CAPACITY=79

POWER_SUPPLY_CAPACITY_LEVEL=Normal

POWER_SUPPLY_MODEL_NAME=901

POWER_SUPPLY_MANUFACTURER=ASUS

POWER_SUPPLY_SERIAL_NUMBER=

Notice the key POWER_SUPPLY_CHARGE_NOW which is used to determine the current charge of the battery:

Code:

$ cat /sys/class/power_supply/BAT0/charge_now 

3237000

On the N900 (on battery) I get this:

Code:

$ cat /sys/class/power_supply/bq27200-0/uevent 

POWER_SUPPLY_NAME=bq27200-0

POWER_SUPPLY_STATUS=Discharging

POWER_SUPPLY_PRESENT=1

POWER_SUPPLY_VOLTAGE_NOW=4012000

POWER_SUPPLY_CURRENT_NOW=307912

POWER_SUPPLY_CAPACITY_LEVEL=Normal

POWER_SUPPLY_TEMP=311

POWER_SUPPLY_TECHNOLOGY=Li-ion

POWER_SUPPLY_CHARGE_FULL_DESIGN=2056320

POWER_SUPPLY_CYCLE_COUNT=22

POWER_SUPPLY_POWER_AVG=315818

POWER_SUPPLY_CHARGE_NOW is missing so the battery monitor has no way to determine the current charge of the battery:

Code:

$ cat /sys/class/power_supply/bq27200-0/charge_now

cat: /sys/class/power_supply/bq27200-0/charge_now: Keine Daten verfügbar

("No data available")

What kernel are you using under Debian? charge_now is available for me with 3.16-rc1 and 3.17 kernels and I've just noticed the the battery level widget is actually working in E17.

Code:

root@debian900:~# cat /sys/class/power_supply/bq27200-0/charge_now

406444

root@debian900:~# cat /sys/class/power_supply/bq27200-0/uevent

POWER_SUPPLY_NAME=bq27200-0

POWER_SUPPLY_STATUS=Discharging

POWER_SUPPLY_PRESENT=1

POWER_SUPPLY_VOLTAGE_NOW=3615000

POWER_SUPPLY_CURRENT_NOW=270249

POWER_SUPPLY_CAPACITY=44

POWER_SUPPLY_CAPACITY_LEVEL=Normal

POWER_SUPPLY_TEMP=276

POWER_SUPPLY_TIME_TO_EMPTY_NOW=5400

POWER_SUPPLY_TIME_TO_EMPTY_AVG=5040

POWER_SUPPLY_TECHNOLOGY=Li-ion

POWER_SUPPLY_CHARGE_FULL=915526

POWER_SUPPLY_CHARGE_NOW=406087

POWER_SUPPLY_CHARGE_FULL_DESIGN=2056320

POWER_SUPPLY_CYCLE_COUNT=114

POWER_SUPPLY_ENERGY_NOW=1322760

POWER_SUPPLY_POWER_AVG=243311

POWER_SUPPLY_HEALTH=Good

It would also be nice if the kernel could provide /dev/rfkill

This should just be a matter of enabling CONFIG_RFKILL in the kernel config file. If you try it and it works, report here and I'll enable it in build_kernel.sh.

It does work if you use the right kernel. It works for me with every kernel that I've tried other than the default 3.16-rc1.

You need both. bq27x00_battery is for the battery monitor chip. In Debian, both are loaded by default.

Is there a way to give regular users write permissions to /sys/class/backlight/acx565akm/brightness

I got the brightness working in E17 as a regular user:

Code:

# chmod +s /usr/lib/enlightenment/utils/enlightenment_backlight

I wouldn't normally recommend a setuid fix (for security reasons) but it appears that this is how it's intended to work. You'll probably want to read through source and verify that there are no obvious exploits before setting this permanently or maybe report a bug so that the package maintainer can do the dirty work ;).

Shutdown options can also be enabled by editting /etc/enlightenment/sysactions.conf.

3.16-rc1
But I just noticed that syslog is full with messages about missing battery calibration.
Maybe that's the reason why I have no full support here.

Sorry for the next part being vague, but I'm tired at the moment and I'm not really used to compiling kernels so I'm not sure about the right procedure.
I first tried setting this in freemangordons-linux-n900/.config:

Code:

CONFIG_RFKILL=1

CONFIG_RFKILL_REGULATOR=m

But it got overwritten during the run of build-kernel.sh.
Then I set it in freemangordons-linux-n900/arch/arm/configs/rx51_defconfig but that file got overwritten too.

So finally I set it in both and disabled this line in build-kernel.sh:

Code:

nice $NICENESS make -j $JOBS rx51_defconfig

Before the kernel was build I got some prompts about building some additional modules (e.g. IPv6) which I all confirmed because I thought some useless extra modules wouldn't hurt and after compiling the kernel I could actually find an rfkill.ko module in freemangordons-linux-n900/modules/lib/modules/3.16.0-rc1+/kernel/net/rfkill

So I copied the whole modules directory (the 2nd one under modules/lib/) and the kernel (by overwriting the old kernel) to the µSD and started the device N900 with it.
I got some error messages about the additional modules but the boot process suceeded. I could login via slim but once on the desktop the mouse didn't work and I had no way to check if the keyboard worked.
So I gave up and restord my backup of the µSD.

I'm on LXDE and I don't think the desktop provides an own CLI interface for brightness. I stumbled upon something on Google code that might help, but I haven't tried it yet:

...so i will only add that, under Maemo, you should have bq27x00_battery module loaded IF you want to use open source BME replacement (for having real battery capacity/current level data, instead of vanilla's BME guesswork) - apart from few other components. See:
http://talk.maemo.org/showthread.php?t=93183

(sorry for a semi-off-topic).

Re: DebiaN900 - A set of scripts to facilitate the installation of native Debian (WIP)

I wonder if this:
http://talk.maemo.org/showpost.php?p...&postcount=134

...might help to have fully working call functionality under Debian? Or at least sound without problems?

Sure, it's not yet fully functional ALSA without pulseaudio crapware altogether, but at least the Nokia pulseaudio bits solved would be still a huge step forward.

xprot is the next thing I will try to finish.

EDIT:
BTW that shouldn't stop you from building what is already being done against debian PA and testing it. with external speakers connected to 3.5 mm jack n900 is perfectly safe.

Re: DebiaN900 - A set of scripts to facilitate the installation of native Debian (WIP)

Is there any way to get SGX working? As I tested about 6 months ago Jessie can run HIldon-desktop, but it really neads GLES.

Another option is major modding for hildon.
