This is a community maintained list of things to do in order to get an appealing DebianDesktop. Your goal is to integrate things into debian and shorten this list.

Selecting the Debian Version

Refer to DebianReleases for information about the Debian versions.

Choose DebianStable, if you want the Computer to just work for a prolonged period of time, without the risk of new packages breaking your habbits or workflow. You may still install selected packages from http://backports.debian.org and http://mozilla.debian.net to get newer versions of specific programms and always use a current web browser.

However, if it is really important to you to always have recent versions of all the software you installed, and you are fine with constantly downloading and installing updates that may stir up a bug every once in a while, you may choose DebianTesting (see that page for more info).

Selecting a Desktop Environment

To select the desktop environment that the debian-installer installs, enter "Advanced options" on the boot screen and scroll down to "Alternative desktop environments". Otherwise, debian-installer will choose Gnome.

KDE is of course a renown heavy alternative.

Xfce is a fast and light alternative, and especially suited if you where using Gnome 2 and find Gnome 3 disappointing.

For older computers consider using LXDE or Xfce, because they are less resource hungry then Gnome or KDE.

Installing

System

Leave the root password empty, to use sudo with your regular password for system administration.

Consider setting RAMRUN and RAMLOCK to "yes" in /etc/default/rcS.

The audio group must not have any members, otherwise consolekit won't adjust audio permissions (acls) if switching between users.

Until bug 646692 is fixed, you need to configure /etc/pam.d/common-session:

echo "session optional pam_umask.so usergroups" >> /etc/pam.d/common-session

to get the correct umask that leverages the private user groups (see group dirs below).

With "green" harddisk models or on laptops, install laptop-mode-tools and set CONTROL_HD_POWERMGMT=1 in /etc/laptop-mode.conf, to stop them from parking/unparking the heads every 8 seconds (clicking noise). (On NON-mobile devices you may even consider using a tool like idle3ctl to prevent load cycling alltogether.) See 'smartctl -a /dev/sdX' for your current Load_Cycle_Count.

If you need a specific program that is not in the repositories, or installed stable and need a more recent version of a program, refer to DebianSoftware.

Consider enableing single-click file opening in the file browser preferences.

If you want to adjust system wide defaults for all users, refer to DesktopDefaultSettings.

Web Browser

Follow the instructions on http://mozilla.debian.net to keep a recent web browser installed on your system.

For secure and sane browsing install the following extensions with the debian package manager: xul-ext-noscript (clean companies from default whitelist), xul-ext-adblock-plus (disable its default whitelist), xul-ext-cookie-monster, xul-ext-https-everywhere, xul-ext-useragentswitcher(set genericly), and xul-ext-refcontrol(set to block). (The squeeze packages are too old for recent browsers, so you need to get them through the Add-ons download.)

Disable third-party cookies, enable deletion of cookies when closing (or disable all cookies), and delete the all cookies you where alread fed with against your independence.

The add-ons HTTPS-Finder and requestpolicy (don't accept companies into your whitelist) may only be available through the Add-ons download.

Consider the betterprivacy extension (Add-ons download) if you need to use the flashplugin-nonfree (non-free repository).

Stop the browser from sending a hash of every Site you visit to google (ready to be added to your hashed browsing track) by disabling the block reported forgery and attack sites options in the security properties.

Disable the search engine "support" and of course the custom google startpage, to prevent the browser from connecting there everytime you start the browser or search something and identifying you reliably in the process. See https://panopticlick.eff.org to find out how generic your fingerprint on the web really is, and monitor your firewall logs to even get to know the strange places your computer connects to.

Enable users to create (windows/cifs) network shares

Install samba (if not present already), then "sudo adduser <username> sambashare" to allow <username> to create file shares.

In squeeze, you also need to edit /etc/samba/smb.conf to be able to allow guest access to shares. Add

usershare allow guests = yes

to the global section, and

map to guest = bad user

below the line "; security = user".

If your router does not resolve local hostnames correctly, and your ISPs DNS servers respond with false IPs instead of returning "unknown", also enable the "name roslve order" line (remove the ";") and move "host" to the end of the list.

Additional packages you may want to install

Use apt-get install <packagename>, or the synaptic package manager to find, select and install the following packages:

(Locally Shared) Group Directories

This explains how to easily share and collaborate on files, pictures, documents, etc. on a multi-user system (e.g. family PCs, servers etc.).

Because Debian uses a user private group (UPG) scheme by default, the default permissions for new files can be set to allow write access to the group (the umask bug we needed to work around above). UPG explanation at RedHat website.

For example, on your home PC you could create a group "family" with "sudo addgroup family", and add the appropriate users to it with "sudo adduser <user> family".

Then create a family group directory: Do "mkdir /home/family", give it to the group with "chown :family /home/family" and change its permissions for example with  chmod u+rwx,g+rws,o-rwx /home/family  to a privately shared set-group-id directory (in octal notation: 2770).

Now all family group members can work with each other's files in the group directory without permission hassle.

If you already have an existing directory full of files (pictures/music/whatever), this script might save you some time.

Some small adaptions could easily support user collaboration by default and out of the box: https://wiki.ubuntu.com/MultiUserManagement


There is another (more complicated) way to do this as well using Access Control Lists (ACLs). Check here and here for more information.

In a nutshell:
apt-get install acl
sarge kernels: filesystems supported -> ext2,ext3,jfs,xfs
etch kernels support: ext2,ext3,reiserfs,jfs,xfs,nfs (with module nfs_acl)
change /etc/fstab options for drive you want to use acls on
ie
/dev/hda5       /pub       ext3    defaults,acl    0       0
cd /pub
mkdir family
setfacl -m d:u::rwx,d:g:family:rw,d:m:rw,d:o:--- family
        this will set the umask of the family directory such that all files created will be -rw-rw----+ and all directories created will be drwxrwS---+. This might not be entirely correct. At the very least, NFS has to be configured for ACLs, or an NFS server on Sarge and NFS Client in Etch can't handle ACLs.
"getfacl family" will show you the permissions.


Desktop Specific Adaptions

Gnome

To create network shares with Gnome's nautilus, install package "nautilus-share".

To enable the greyed "Password: not asked at login" option for users in System > Administration > Users and Groups (Needed for (guest) account switching in addition to auto login.): Create the nopasswdlogin group,

sudo addgroup --system nopasswdlogin

and add the following to gdm's pam config in /etc/pam.d/gdm:

auth sufficient pam_succeed_if.so user ingroup nopasswdlogin

Make sure this line goes right before the "@include common-auth" line. You can use 'sudo adduser <user> nopasswdlogin' to add a user to the group.

Xfce

For network browsing, install gvfs-backends and gvfs-fuse and add your users to the 'fuse' group (sudo adduser <user> fuse). In squeeze, you also need to install and use gigolo, because the thunar file browser version in sqeeze is not yet able to browse network shares (windows/cifs) directly.

To create network shares with Xfce's thunar, follow these steps.

Install catfish to be able to search for files.

In wheezy, you can get rid of the space consuming "dock" thing by adding the desired starters to Pannel 1 and deleting Panel 2 in the Pannel settings. You can move the panel to another location on the desktop while it is unlocked it in the settings.

For passwordless user swiching, you may create and enable a nopasswdlogin group as described for gnome, if you are using gdm (the default).

If you want gui configuration tools, you may install gnome-disk-utility (palimpsest) and 'apt-get --no-install-recommends install gnome-system-tools'.

Finally

...have fun! And if you encounter bugs search the net, if the bug is not already filed, find the appropriate package and file a bug against it. If it concerns Debian you can use the "reportbug" utility for that.
