[Hackers/Devs Only] Collection of Low-Level Config-Files / Tools - maemo.org

BlueGene | # 1 | 2010-01-10, 15:28 | Report

In this thread I'd like to collect a list of system configuration files, lowlevel-tools and oneliners. When there's enough content, I will make a wiki-page. Feel free to contribute :-) !

Remember: Modify these files only if you know what you're doing! Understanding how to work with textbased applications is a must!

Type

Code:

<command> --help

for additional info.

Interesting System/Hardware config files in Maemo 5:

Powerbutton-Interface:

Code:

/etc/systemui/systemui.xml

Hardware button/LED/vibration behaviour:

Code:

/etc/mce/mce.ini

Keyboard Stuff:

Code:

/usr/share/X11/xkb/
/usr/share/X11/xkb/symbols/nokia_vndr/rx-51 (Keymaps of onboard kb)

Repositories:

Code:

/etc/apt/sources.list

Editing /etc/apt/sources.list.d/hildon-application-manager.list directly is pointless since HAM overwrites it.
Instead, you should edit:

Code:

/etc/hildon-application-manager/catalogues

or invoke the config script with the proper arguments:

Code:

hildon-application-manager-config add <FILE>

Welcome Video:

Code:

/etc/hildon-welcome.d/default.conf
/usr/share/hildon-welcome/media/

Animation behaviour (transitions, zooms):

Code:

/usr/share/hildon-desktop/transitions.ini

App Menu:

Code:

/etc/xdg/menus/hildon.menu
/usr/share/applications/hildon/ -> .directory files / .desktop files
Icons: /usr/share/icons/hicolor/48x48/hildon

Configtools:

Hardware Status

Code:

lshal
e.g.    lshal | grep battery

Software Settings/Options

Code:

gconftool-2 -R /
(returns all possible options/settings of gconf)

Keyboard Shortcuts
Description how to setup keyboard shortcuts

Status Menu Configuration Tool:
powatool

Better Menu Structure:
mymenu (repository: deb http://qole.org/repository maemo fremantle)

Basic access/modifikation tools:
I prefer modify, install and update via ssh, these are my most used tools:

Code:

openssh
putty (when i login from windows)
vim
grep
apt-get
apt-cache
dpkg

Search/Install/Update Packages:
Works almost like in every debian-based distro:

Code:

apt-get install <program name>
apt-cache search <string>
apt-cache showpkg <program name>
apt-get update (updates the cache from repositories)
apt-get upgrade (installs newest version of installed packages)
dpkg -i <.deb file> (installs .deb file)

Firmware Upgrade (Since 1.0.1):
Careful with thisone, link /var/cache/apt/archives to somewhere with enough space!

Code:

apt-get dist-upgrade

Reboot to see all the changes.

List of Devtools:
http://wiki.maemo.org/Documentation/devtools/maemo5

X-Forwarding to Unix-Computer
On Maemo 5, install xauth:

Code:

apt-get install libxmuu1

Now X-Forwarding works (quite buggy though):

Code:

ssh -X root@<deviceip>

In any opened window press F4 to access the menu.

Shortcuts:

http://wiki.maemo.org/N900_shortcuts_and_gestures

Hacks:

Fullscreen-Mode for XTerm:

Code:

gconftool-2 -s /apps/osso/xterm/toolbar -t bool "false"  (to return to menu press ctrl+backspace)

SAMBA / CIFS (Windows) FS access:
http://talk.maemo.org/showthread.php...highlight=cifs
Automount in /etc/fstab:

Code:

//server.name.or.ip/share /home/user/some_directory  cifs   noauto,uid=29999,ro,nosuid,nodev,user=<user>,pass=<pass>,ip=<ip>

Installing gcoreutils (Thanks to Ruski for the repo):

Code:

echo "deb https://repo.codemages.net opt/" >> /etc/apt/sources.list
apt-get update && apt-get install gcoreutils

Repartitioning the device (don't try this if don't understand every single command!):

Nice.. some quick comments

For the shortcuts you can link to the wiki page:
http://wiki.maemo.org/N900_shortcuts_and_gestures

About the "apt-get dist-upgrade"; it should be removed completely. It doesn't work like in Debian.

man will work nicely on most Unices, but hasn't it been stripped out of Maemo?

Great topic idea for devel/customization, I'll keep an eye there

It seems so, or at least on my device man dirs are empty and no man binary available on the env (as root "find / -iname man | grep -i bin" returns nothing, so seems like no man binary on maemo5).
Would be a great idea to have some man on maemo (even as extra package) for cli programs...

jebba | # 6 | 2010-01-12, 01:12 | Report

The problem is that even if you had man, you wouldn't get the man pages because HAM is set up to not install docs and manpages to save space. I have 48G on my device, yet need to save a few k of manpages, gah.

Thanks, I didn't realize that, because I never use HAM ;-)

Added some information how to setup X-Forwarding.

Does somebody know how to get this output to xephyr in a oneliner or a little script? Probably this would provide a better view.

Just upgraded to PR1.1 with this command:

Code:

apt-get dist-upgrade

I really begin to feel at home with this device ;-)

EDIT: I was a little quick to post this ;-) If you don't want to experiment, don't do this :P I'm still working on some issues... mostly because of not enough space on rootfs.

EDIT2: Bricked it while updating. It just restarted and wouldn't come up anymore. Seems this is NOT a proper way to do such a big update ;-) ...

I haven't tried it with PR1.1, but I have dist-upgraded in the past (including kernels). You probably ran out of space because by default apt uses /var/cache/apt and that filled up root. You should do something along the lines of:

Code:

apt-get update -o dir::cache=/home/user/MyDocs/.apt-archive-cache

apt-get dist-upgrade -o dir::cache=/home/user/MyDocs/.apt-archive-cache
