These are my personal notes - nothing comes with warranty! Use at your own risk
[edit] My N900 setup
[edit] Reparitioning
THIS CAN MAKE IT A BRICK SO BE PREPARED TO RESTORE FROM FLASHER OR ANY OTHER WAY YOU CAN THINK OF
What I did to get a 50/50 sharing of memory and /dev/mmcblk0p2 still be ext3. Be extra careful because I've never made it to get it done with one shot (after I had it successfully set up, I have never done it again ;)). So it is more a guideline than a "how to".
Minor benefit of this setup is that memory is equally shared between ext3 and vfat and that vfat and ext3 are still on the same partition. Other reparitioning guides swap them, then you will need to edit some scripts for usb exporting the discs - which is easy but I didn't want that.
- do full backup on desktop computer with rsync. For an example see User:Jebba/Backups
- flash eMMC. See Updating tablet firmware and User:Jebba/Flash
- flash device. See Updating tablet firmware and User:Jebba/Flash
- install rootsh

[edit] Remove boot video
vi /etc/hildon-welcome.d/default.conf
Put and # at the beginning of the second line
[edit] Customize media tracker
vi /home/user/.config/tracker/tracker.cfg /home/user/.config/tracker/tracker.cfg #restarting tracker afterwards tracker-processes -r #or even tracker-processes --hard-reset
E.g. I disabled /media/mmc1 tracking.
[edit] Customized program list
Source: http://talk.maemo.org/showthread.php?t=37874&highlight=hildon.menu
You can add folders an rearrange the icons application launcher by editing the file /etc/xdg/menus/hildon.menu or /home/user/.config/menus/hildon.menu for newer versions of maemo. The <Filename>'s in the Include section set the icons to display, so you can rearrange them or remove the ones you don't want. Adding more Menu sections will add folders (the one there represents the More..). Replace the OnlyUnallocated/ and All/ with a list of filenames for the apps you want in the folder (see the files in /usr/share/applications/hildon ).
Icons can be found under /usr/share/icons/hicolor/48x48/hildon/.
[edit] Customized power button menu
vi /etc/systemui/systemui.xml
Search for e.g. reboot and enable the reboot entry, by setting the comments to a different place.
[edit] Not optified?
Some programs that I think, that could not be optified (df checking).
ogg support - maybe okay ^^ libqt - maybe okay ^^ fbreader qalculate gtk version
[edit] Scribble
cat /var/lib/dsme/boot_count You tried deleting everything in /var/cache/apt/archives/ yet ? apt-get autoremove
[edit] Keepassx database issue
You can give the database filename as the command line argument. For example, if you want it to open the file /home/user/MyDocs/Database.kdb automatically, you can do that by changing the Exec line in /usr/share/applications/hildon/keepassx.desktop to
Exec=keepassx /home/user/MyDocs/Database.kdb
[edit] Tracker
Tracker is the process that tracks all media librarys of maemo.
tracker-processes -r #will reset the tracker databases, useful when changing the tracked directories

[edit] Building a package for maemo
Currently I only collect links. Maybe when I'm more experienced in building a package I write a guide - currently I'm happy to get it somehow to work.
