Hy

I have installed Xmonad on our little beast and it works suprisingly well, it is fast, stable, low on mem ...
only downside is pretty large ghc as dependency (cca 600 mb) and lack of n900 Alt_l aka Mod1 key,
so I assign it to volume key and it works well.

Is there a way to assign '$ xset dpms force off' to kb_lock?
I found workaround but doesn't involve kb_lock.

Does anyone got audio working?
I've tried alsamixer, but moc doesn't give any response. :(
Then I tried with jack, in moc you can see that song is at least playing but there is no sound.:confused:

I've managed something with keyboard leds.

Here is a simple script:

Code:

#!/bin/sh



# there are different modes: run disabled load. I use run for ON and disabled for OFF

mode="run"



# 0-255

brightness="50"



echo $mode > /sys/class/i2c-adapter/i2c-2/2-0032/engine3_mode



echo $brightness > /sys/class/i2c-adapter/i2c-2/2-0032/leds/lp5523:kb1/brightness

echo $brightness > /sys/class/i2c-adapter/i2c-2/2-0032/leds/lp5523:kb2/brightness

echo $brightness > /sys/class/i2c-adapter/i2c-2/2-0032/leds/lp5523:kb3/brightness

echo $brightness > /sys/class/i2c-adapter/i2c-2/2-0032/leds/lp5523:kb4/brightness

echo $brightness > /sys/class/i2c-adapter/i2c-2/2-0032/leds/lp5523:kb5/brightness

echo $brightness > /sys/class/i2c-adapter/i2c-2/2-0032/leds/lp5523:kb6/brightness

Create two of those (with changed values), chmod it, put in path, add a line in visudo so you don't have to write password every time and enjoy typing in dark:cool:

Probably there is some more elegant way to achieve keyboard led on/off but...

Script for voltage, capacity and temperature

Code:

#!/bin/sh





# status

stat=$(cat /sys/class/power_supply/bq27200-0/status) 



# time

if grep Charging /sys/class/power_supply/bq27200-0/status > /dev/null

        then

time=$(cat /sys/class/power_supply/bq27200-0/time_to_full_now)

        else

time=$(cat /sys/class/power_supply/bq27200-0/time_to_empty_avg) 

fi





# capacity

cfd=$(cat /sys/class/power_supply/bq27200-0/charge_full)

cn=$(cat /sys/class/power_supply/bq27200-0/charge_now)



# voltage

vmd=$(cat /sys/class/power_supply/rx51-battery/voltage_max_design)

vn=$(cat /sys/class/power_supply/bq27200-0/voltage_now)



# temp

temp=$(cat /sys/class/power_supply/bq27200-0/temp)



# out

echo status: $stat

if grep Charging /sys/class/power_supply/bq27200-0/status > /dev/null

        then 

echo $time | awk  '{ printf  ("time to full: %.2d:%.2d\n" , ($1/3600%24) , ($1/60%60)) }' 

        else

echo $time | awk  '{ printf  ("time to empty: %.2d:%.2d\n" , ($1/3600%24) , ($1/60%60)) }'         

fi

echo $cn $cfd | awk '{ printf ("capacity: %.1f%%\n" ,  ($1/$2*100) ) }'

echo $vn $vmd | awk '{ printf ("voltage: %.1f%%\n"  ,  ($1/$2*100) ) }'

echo $temp | awk '{ print "temp: " $1/10 "°C" }'

This works. But row:

Code:

echo 3 > /sys/class/i2c-adapter/i2c-2/2-0032/select_engine

gives error

Code:

lp5523x 2-0032: firmware request failed

Re: debian jessie image for N900

Thanks for pointing it out, I overlooked it.
It seems that when you set mode run in engine_mode it automatically set which engine is active in select_engine, so

Code:

echo 3 > /sys/class/i2c-adapter/i2c-2/2-0032/select_engine

is unnecessary.

I've edited batt_info and kbd_led script.
bat_info is now more verbose and kbd_led doesn't produce error.

Re: debian jessie image for N900

Here follows how to mount maemo fs from inside debian (from http://talk.maemo.org/showpost.php?p...2&postcount=61).

Code:

apt-get install mtd-utils

modprobe ubifs

ubiattach /dev/ubi_ctrl -m 5

mount -t ubifs ubi0:rootfs /mnt

mount /dev/mmcblk0p2 /mnt/home/

mount /dev/mmcblk0p1 /mnt/home/user/MyDocs/

For a chroot shell:

Code:

for i in sys dev proc; do mount -o bind /$i /mnt/$i; done

chroot /mnt /bin/sh

When done, undo:

Code:

fuser -k -M -m /mnt/

for i in sys dev proc; do umount /mnt/$i; done

umount /mnt/home/user/MyDocs/

umount /mnt/home/

umount /mnt

Re: debian jessie image for N900

For a proper keyboard on X, run the following:

Code:

setxkbmap -rules evdev -model nokiarx51 -option grp:ctrl_shift_toggle -layout us

Please post if you know how to properly configure this in e17.

mount /dev/mmcblk0p2 /mnt/home/

mount /dev/mmcblk0p1 /mnt/home/user/MyDocs/

I have some difference when booted to jessie from sd-card:

Code:

/dev/mmcblk0p2 on / type ext4 (rw,noatime,data=ordered)

And maemo's home is: /dev/mmcblk1p2
And maemo's vfat MyDocs is: /dev/mmcblk1p1

[CODE]
setxkbmap -rules evdev -model nokiarx51 -option grp:ctrl_shift_toggle -layout us

Please post if you know how to properly configure this in e17.

First create the following file

Code:

nano /usr/share/applications/keybset.desktop

with the following

Code:

[Desktop Entry]

Name=Keybset

Comment=Sets the RX-51 keyboard layout

Exec=setxkbmap -rules evdev -model nokiarx51 -option grp:ctrl_shift_toggle -layout us

Icon=false

NoDisplay=false

Terminal=true

Type=Application

Categories=

StartupNotify=true

After that make it executable

Code:

chmod a+x /usr/share/applications/keybset.desktop

Then goto Settings panel>Extensions Tab > Modules > Settings Tab And activate Applications module.
After its activated in Settings panel,Apps tab find Startup applications and activate Keybset.Your done
The only problem is that left and right arrows dont work for me.
