Recommended to-do after install

To-do list after successful install (Xubuntu).
Some things here are Xubuntu-specific, others generic, and some are specific to my installation.
Also, about half of following content is already mentioned in posts-before. But, as I myself found out - it's hard to remember everything about installation after 1.5 month of happy Xubuntu-ing.
For things before and during install - look into numbered posts in February.

1.|Xfce| Create your own menu items and menu-tree for future customization: Copy contents of /usr/share/applications to ~/local/share/applications (menu-items of Xfce main menu);
Copy /etc/xdg/menus/xfce-applications-menu file to ~/.config/menus/xfce-applications-menu (see Xfce wiki page, and page here).
2.|General| Install proprietary drivers.
Go to 'Software sources / Additional drivers'. My video card is Nvidia, so I pick Nividia and wait it to install (If you have some other types of drivers present there, install them). Now, type in terminal: sudo nvidia-xconfig (not sure - maybe it will be created automatically when rebooting...). Do not reboot yet.
Now is good time to do some other things which also require reboot. Reboot comes after (4) Update software is done.
3.|My bug, but maybe a known bug| Mounting wallpaper folder - for avoiding that Manager forgets added wallpapers every time when its closed.
Mounting description is in this post.
3a.|Grub2| Remove Memtest entries from Grub2' boot menu (if you do not love them for some reason). How to description is here.
3b.|LightDM| Remove un-needed sessions from greeters' menu: About that go here.
4.|Quite General| Your Xubuntu is already whining persistently about updates. Magnamiously say Ok and let it dowload & install ... like - a lot. Probably it also had kernel updates...
4a.|Xfce| During updates: Windows tweaks - check compositor 'on'. Look what you really need to start in 'Startup and Sessions', adjust mouse-double-click speed=400, ... Move panels around, do some preparations - make separators visible, drag some launchers to panel and delete some from panel...
Updates done, REBOOT NOW.

Arriving back to desktop.
5.|Xubuntu| Install Synaptic from 'Ubuntu Software Center'. Open it and get 'xubuntu- restricted-extras' (Mind - you have to say 'yes' once in this process, or installation stalls and waits...)
Stay in Synaptic. Change search mode to 'Status', pick uninstalled, use queries in type like: xfce, xfwm4, samba, font-manager, ...
Or whatever you fancy if you have enough time to spend: artwork, theme, engines (murrine, unico, pixbuf, nodoka, aurora, equinox...).

And continue now as you wish:
- Copy back Your Things from backup you wisely created before crapping out your previous Linux install...if there was one.
- Make .gtkrc-2.0 file into ~/yourusername-folder. It would be the last instance of gtk-preferences file which overrides gtk from themes - so you don't have to hack themes themselves. Look for clock-bit here, or maybe the following below is useful:

# Desktop-icon-text to white #
    style "xfdesktop-icon-view" {
    XfdesktopIconView::label-alpha = 0
    fg[NORMAL] = "#FFFFFF"
    fg[SELECTED] = "#FFFFFF"
    fg[ACTIVE] = "#FFFFFF"
    }
widget_class "*XfdesktopIconView*" style "xfdesktop-icon-view"

# xfce-panel background and text color, minimalistic #
style "panel"
    {
bg[NORMAL] = "#3685d5"
    fg[NORMAL] = "#ffffff"
    }
widget_class "*Panel*" style "panel"
widget "*Panel*" style "panel"
class "*Panel*" style "panel"

- Add 'lock screen' item to Menu: Command (exec) is xflock4.
If available, use menu editor, if not, make new .desktop file manually and add entry to 'xfce-applications-menu' file (the same which should be now in your  ~/.config/menus/ folder.
- remove unwanted stuff from Menu.
- Bling: Search xfce-themes, xfce-icon, artwork, xfwm, goodies in Synaptic.
Take into account when installing packages automatically, everything goes to root. When dowloading separately from web art-sites (example) - choice of place is yours. Things in ~/home are, of course, yours and editable without 'sudo'. NB! Themes installed only to ~/home probably are not accessible to some apps...
Install Compiz - if you really are in for eyecandy.
Docks: Plank dock is real simple. Docky is more fullsome - but brings along all kind of Gnome crap (inc zeitgeist), Once-favourite AWN is dead. Cairo is ultimate available bling - sparky and jumpy.
- Install apps you like - short description what I like is here.
Some apps I (maybe) didn't mention:
Blender - 3D tool like 3DMax. Geeqie - another thumbnail viewer. Easytag for organizing tags of mp3-s. Geany - more advanced text and programming editor. And Cdemu - cd emulator like Daemon Tools.
- When first fever of installation is over, install Bleachbit - and clean up useless languages, temp files, archive backups and so on and on. Bleachbit is quite helpful, gives warnings when appropriate and lets you preview changes before commit.
Do whatever.
