Jolicloud is not the first Linux distribution I have installed on my Samsung NC10… I’ve tested also Ubuntu Jaunty/Karmic, Fedora, Arch Linux and Moblin (latest snapshot).

Which is the technology behind Jolicloud?

Basically Jolicloud is a derivate of Ubuntu Netbook Remix with wide Prism usage across the desktop environment: the majority of “applications” you have seen in the screenshots are small packages which provide an independent Prism session on a specific website: for example, if you install the twitter application you will get a new icon inside your application list, that icon will start a new fullscreen Prism session for twitter.com.
Common desktop applications are also included, like Firefox or VLC, but it is highly focused on web services.

Installation

It is just like Ubuntu, nothing more/nothing less (you are in the Jolicloud desktop, but the installer is the same used by Ubuntu).

First Run

As said, the “core” is an Ubuntu Netbook Remix, so we firstly see an Usplash booting sequence (nice and simple theme)…

Followed by the GDM session (simple and nice theme too)…

After the login procedure the desktop environment starts. It’s a GNOME desktop with the Netbook Remix session: the custom panel on top shows the title of the current application in the middle, a list of the running application on its left and the status icons on its right. In the center of the screen Jolicloud asks to login on the website and then it opens the default screen you might have already seen (the dashboard shown in the screenshots is nothing more than a Prism session running http://my.jolicloud.com).

Jolicloud is now ready.

The home screen, dashboard, how do you call it

As said, the main screen is a Prism session (so a website, no Clutter, no Cairo, no Gtk+…) with useful links to your applications and your settings. It is great to see how it is simple to use, really: installing and removing applications is a matter of a click, browsing and viewing the catalog of applications is very easy. For everyone. I like it.

Running applications

The separated fullscreen Prism sessions work surprisingly well… In the reality you’re running a web browser, but they give you the feeling that they are just like normal applications: if you run gmail, twitter, facebook (etc etc) you have their icons in your taskbar and you switch between them like they were a real application.

It’s the web now the protagonist of your netbook because you are actually using each web 2.0 service as an individual application: something that has been imagined for years by almost every company (Microsoft too) realized in Jolicloud really well.

A desktop replacement?

This distribution is absolutely amazing to surf the web when you’re on a train, in the university, when you just want your social websites up and running, when you want to update all your services and work with your documents.
But just like Moblin, in my opinion it is not meant to replace your Ubuntu… it will be likely added to your grub in a small partition dedicated to your social virtual space. And that is a good thing… when you need you have a quick access to the web. Great!

Comparison with Moblin

They are two completely different projects, even if they share the same love for the web.
Moblin is like a smart interface for your netbook providing a mix of useful applications with incredible tecnologies behind (KMS, fastboot, Clutter…) optimized for your netbook, with Jolicloud the web becomes your operating system (it provides the applications) trough an efficent environment for your small laptop.
I’m sure they will live together on my hard disk soon

I own a Samsung NC10 with an Intel Atom N270 and an Intel GMA 950 (i945). I’m running both Arch Linux (i686) and Ubuntu jaunty (lpia).

Few notes:

• This how to should work with any netbook, since they share almost the same hardware.
• I haven’t used a benchmark, but applications (Firefox, Gnome Do’s Docky, KDE 4 and more), and the difference is so visible that it doesn’t require a benchmark.
• I don’t know if it depends on the lpia architecture (I’m running Ubuntu lpia) or some patches applied to the drivers, but Ubuntu’s 2D graphics are a little bit faster than my Arch Linux installation with kernel 2.6.30 and drivers 2.7.1 (same versions).
• I had the boost in both Arch Linux and Ubuntu, though Ubuntu is faster.
• I’ve compared the 2D graphics with Moblin too, but its newer drivers using UXA are noticeably slower (Firefox/Gecko is incredibly slow when scrolling heavy webpages like facebook or my custom gmail).
• Newer Intel drivers (2.7.99.x and similar) support only UXA acceleration, and they perform a little bit slower than 2.7.1 without greedy migration heuristic (unfortunately that means a big difference). Greedy migration heuristic does not work with UXA.
• With this new combination, 2D graphics are really close to my Windows XP installation (Firefox scrolling).

Instructions (Ubuntu lpia combination, adjust the steps to your distro):

1. Install kernel 2.6.30 from this ppa (even if it has the “nc10″ tag, it doesn’t have custom patches and should work with any netbook).
2. Upgrade your Xorg Intel drivers with the 2.7.1 version on the same ppa.
3. Enable greedy migration heuristic creating an empty /etx/X11/xorg.conf with those lines:
   

   Section "Device"
Identifier "Intel"
Driver "intel"
Option "AccelMethod" "exa"
Option "MigrationHeuristic" "greedy"
EndSection


4. Optional: install client-side-windows Gtk+ branch (helps Gtk+ scrolling and resize).

I really hope you will get the same boost I had, and I’m looking forward to newer Intel drivers: it is just question of time… the team rewrote both xorg driver and the DRM code to ensure a great future to these video cards, and the performance drop is physiological to the transition… I suspect UXA will achieve those performance in less than a year…

The thing is: I don’t have time for it in these months.

So, if someone wants to write a small patch for it… it will be merged!

Have a good weekend…

Here’s the link, if you want to share it and join it: GNOME Italia on Facebook

Ho appena creato il gruppo ufficiale (o meglio, il primo e quindi ufficiale ) “GNOME Italia” su Facebook…

Ecco il link, se volete condividerlo e aggiungervi: GNOME Italia on Facebook

Ubuntu Jaunty is out (it has some issues) and for a better linux experience with this netbook there’s a PPA and a Forum (I signed up today, it has both an English and an Italian section)!
So, if you are a NC10 owner, bookmark these links and spread the voice to your friends!

OT: I forgot to say I have released murrine 0.90.3 few weeks ago with a bounce of fixes to the focus drawing function…

Talking about Murrine, I’ve released 0.90.1 and 0.90.2 which contains mainly bugfixes.
0.90.1 was relased with a typo (sorry!!!) which caused a crash, thanks bitzer for pointing that out.

Changelog for 0.90.1

Changes in this release:
- High roundness values are now correctly limited.
- Use focus_color in draw_entry if the theme uses it.
- Removed shadows from GtkCombo and GtkComboBoxEntry.
- Code polishing and bugfixing.

Changelog for 0.90.2

Requires Gtk+ 2.12.0
Changes in this release:
- Fixed a crash when using focus_color.
- Now focus_color and scrollbar_color accept symbolic colors.

Download

Wow, new rockin’ release!
Enjoy.
Download the source code!

Changelog

Too many changes to be listed, let’s take a summary.
This new version is extremely customizable with a huge number of new
options. Those new options allow the user to achieve an incredible
variety of styles.
In order to add those features the engine was rewritten in many parts,
sometimes even 2 or 3 times! This results in a simpler code, more
readable and more maintainable, with a lot of custom code moved from
each widget drawing function (before) to a general murrine drawing
support file (now). For example adding a new glaze style will now cost
about 20 lines and it will be applied immediately to every single
widget.
Murrine can finally use the alpha channel to draw a real transparent
theme, all it needs is an application using the RGBA colormap and a
theme with the rgba option enabled.
During the whole development, murrine was kept in sync with
every bugfix that hit gtk-engines, so this new version can also be
considered much more stable than the previous one.

UPDATE: should be out soon http://download.gnome.org/sources/murrine/0.90/

I’m still not sure but maybe I will publish a Murrine development release in this weekend (with development I mean it won’t be called 1.0, maybe 0.90 or similar).

I’d like to have it included in Jaunty, because ubuntu is actually shipping an old bugged svn snapshot and I’m a bit tired of closing bugreports about that obsolete version.

If you have some last requests, please take a look at that post.

I need ideas

This post remembers you that I’ve opened a section where you can easily submit your mockups for Murrine. Use gnome bugzilla for Clearlooks.

I’m going to share with you my glitch-free experience:
just recordered, sorry for the white noise but the netbook’s speakers have a low power noise removed thanks to audacity.
pulseaudio-frozenbubble-no-noise (FLAC, 1.8 MB, I can hear more glitches here)
pulseaudio-frozenbubble-no-noise (WAV, 3.2 MB)
pulseaudio-frozenbubble (FLAC, 2.0 MB, I can hear more glitches here)
pulseaudio-frozenbubble (WAV, 3.5 MB)

Pulseaudio 0.9.14, snd-hda-intel (Realtek ALC 272), Fedora Core 10.

Also, CPU usage for pulseaudio is between 10% and 35% (and ~25% without the g-f feature). Not really fun for the laptop’s battery.
