Hi, Jonne.
I try  to  install realXtend-Naali-N900-0.2.0.  I  taked it  here realXtend-Naali-N900-0.2.0.
  I have  read your  file READ:
realXtend Naali N900 edition
============================
WHAT YOU NEED BEFORE INSTALL
1. The 1.2 firmware
    Make sure you have the 1.2 firmawe installed on your device. Naali uses Qt 4.6.2 so this is not optional.
   
2. Maemo extras devel repo
    Add maemo-extras repo in you app manager http://wiki.maemo.org/Extras-devel#How_
 … ras-devel. Please read the warning notes from top. If you are not 
comfortable with what you are about to do. You can stop this right here.
 Naali is in early dev phase also so the same warnings applies to Naali.
 I would not go as far as that you would need to flash your device due 
to Naali but this is not complete software.
3. rootsh
    You can get this from the Application Manager.
    You need this for later steps to install packages and when copying naali shortcuts into the system folders.
4. unzip
    sudo gainroot
    apt-get install unzip
   
5. QtScript 4.6.2
    For me the 1.2 firmware update did not include QtScript but you can install it manually:
    sudo gainroot (if not as root already)
    apt-get install libqt4-script
   
6. GLES1
    Some games may have already installed this to you. Check that you have it:
    sudo gainroot (if not as root already)
    apt-get install libgles1
   
INSTALLING AND RUNNING NAALI
1. Open a terminal and you should be now in ~/ that is /home/user/. You 
can verify this with 'pwd' command. You should open a new terminal so 
you are not in root mode. Or type 'exit' if you are.
    mkdir naali
    cd naali
    cp /home/user/MyDocs/naali/setup-naali.sh .
    cp /home/user/MyDocs/naali/setup-naali-shortcuts.sh .
    chmod +x setup-naali.sh setup-naali-shortcuts.sh
   
2. Run the scripts
    NOTE: DO NOT RUN NAALI SETUP SCRIPT AS ROOT. Make sure of this.
    ./setup-naali.sh
    sudo gainroot
    ./setup-naali-shortcuts.sh
    exit
   
3. Make shortcut and/or run
 
   NOTE: DO NOT RUN NAALI THE FIRST TIME AS ROOT. This will create 
configs and files with root access only and later runs you wont be able 
to access them in write mode.
    You can now add a desktop shortcut to naali from the usual N900 path. Or start naali from terminal with.
    cd /home/user/naali/naali/
    ./start And 
etcetera
...
 But  i  have  some  truble  here:
2. Run the scripts
    NOTE: DO NOT RUN NAALI SETUP SCRIPT AS ROOT. Make sure of this.
    ./setup-naali.sh
    sudo gainroot
    ./setup-naali-shortcuts.sh
    exit   I think is it  becouse root.I have the line:
Permission  denied.
I  did not  find  how  to  be
Make sure of root.
I  only  can  type 'pwd'
  And  it  will  line  without  root.  Can  you  help me?
 Else,  i  want say to  you  big thank you  for your
program work and patience. I  want  use  it.
 My respect to you, Sofya  Kassaye
