GNOME 3.0 Beta v0.0.6 Impressions

GNOME 3.0 is due for release April 16 and I’m pretty excited by it. So I finally decided to check out first-hand how it’s progressing. My perspective is that of a GNOME 2.X user, but like many people, I was a little skeptical of the changes in 3.0. I tried the 0.0.6 image from the GNOME3 website and ran it off the USB key.

The Good

  • It’s pretty. And minimal. Love the new font.
  • High quality and scalable graphics and interface – tried it on both a 10″ netbook and a 23″ monitor with success. Large title bars and close buttons – easy to hit.
  • All the updated core GNOME programs! I especially like the progress with Nautilus, the file manager. Instead of using a status bar, it uses a floating alt-type yellow info box to display info. Plus it seems much faster.
  • Single stroke exposé-like effect that reveals all windows, scaled and tiled. This is bound to the Windows (Super) key, which actually makes it more appropriately named for GNOME3 than any version of Windows. Note: It can also be reached by clicking Activities in the top-left corner. From here, you can use your mouse to switch to a window or quickly close windows, launch/switch-to a program from the left sidebar, or you can start typing a substring of a program to run, or a string to search using wikipedia or google (these options appear after you type something… OR you can browse applications by clicking Applications. Additionally, on the right, you can manage workspaces. With the smart launcher and window manager functionality tied to a single key, I found myself actually starting to heart the windows key and its prime keyboard real estate.

  • Don’t worry, you can still alt-tab! 🙂 And it’s improved, with mouse input, and grouping instances of the same program.

  • Integrated chat with notifications is great.
  • Modal windows are now attached to their parent window (by default, this can be changed).
  • Slick animations with meaning. Like the modal windows that slide out of the parent window’s title bar. I think OSX does something like this….
  • Yelp, the Help browser is about a billion times faster. Seriously. This is largely due to the shift from gecko to webkit, I believe.
  • No more minimize/maximize buttons. At first, I wasn’t sure about this and thought I wouldn’t like it, but the way the new desktop is designed, I don’t miss them. You can add them back, if it’s a concern. And all the old window shortcuts still work: [Alt+F9] = Minimize; both [Alt+F10] and [double-click title bar] = Toggle Maximize; [Alt+right-mouse-button] = window menu.

  • GNOME is just much leaner than it has ever been before. Instead of starting 3 different programs at login (nautilus, gnome-panel, metacity), it simply starts gnome-shell.

The Bad

  • Requires 3D support. Unfortunately, this is not always a simple request for us Linux users. Tried it on my netbook and failed. Couldn’t run it and probably never will thanks to the terribly supported poulsbo integrated graphics.
  • And not just any 3D support… Tried it on my desktop, also with integrated graphics, but a better supported ATI x1250 – performance wasn’t stellar, but it was usable.
  • Not very mature and not very customizable (yet). Panel Applets in prior versions of GNOME are extremely popular. Now we have this huge piece of space we can’t do anything with. But I’m sure something like panel applets will come eventually.
  • It’s really hard to train myself to look to the middle of the top panel for the time/date… I keep looking at the top-right. 😛
  • Some of the changes had me fishing for functionality. Like, where is the control-center? It’s not in the Applications list under the Activities window. It’s under the user menu, under System Settings.

    And once you’re in the System Settings, you often want to change many things. At first, I was opening System Settings, selecting a component (they’re called Panels) to adjust (Background, for example), making changes, closing, repeat. When you open a panel from the System Settings window, that panel replaces the contents of the System Settings window. I didn’t notice the All Settings button that replaced the search entry in the dark grey area! After realizing that, it wasn’t so bad. 🙂 And to be honest, I think the theme or something is not quite finished. Looking at other screenshots on the web, the button is much more noticable.

The Ugly

  • BIG change in the way it expects people to use it. This will likely cause lots of frustration.
  • Doesn’t quite seem ready for prime time. I guess that makes sense, it’s still beta.
  • Some odd input lag every now and then. Visual artifacts. For both of these, I point my finger at my integrated graphics. Just a general lack of polish. But that’s to be expected with alpha/beta software.
  • Bold, black window titles with same-colour shadow. Ugh… I expect that will change soon. 🙂

After trying Shell, I’m actually more excited for it. It still lacks polish in areas, which is expected at this point, but I love the direction GNOME3 is taking GNOME. I’m hoping I can get by on my integrated graphics, but I’m probably willing to purchase a low-end video card to get better performance. Anyway, I’m really interested to see how Canonical’s Unity and GNOME Shell will evolve side by side. Now I have to try Unity, I guess….

File List Applet – GNOME Panel Applet

This is kind of a proof of concept I’ve been playing with. The idea is that finding a file within a folder is often easier by type, and you are often only interested in the most recently modified file. The problem with a file manager is that although you can easily sort by either type or modification time, you cannot filter your view of all the other files you’re not interested in. I previously wanted to address this issue within Nautilus, (and I still believe this functionality would be wonderful in Nautilus), but I ended up doing this much less ambitious applet as a proof of concept.

This applet will let you add any number of folders to it, and will try to categorize the files automatically and intelligently. Currently, it’s more automatic than intelligent as it just looks at the mime-type. Even so, I’ve found it especially useful for keeping track of all my downloads:

Steven is catching up on the latest on planet.gnome.org and has downloaded a couple screencasts demoing the latest and greatest. These files are typically 2-10 megabytes, so they didn’t download instantly. Steven continues reading and forgot about the screencasts until a couple hours later. At that time, he can simply click on the File List Applet, select Downloads, select Video, and look at the top of the list for the newest files. Steven is happy. When finished, he can follow the same process to delete them – without once opening his file manager and being assaulted with ALL the files in his Downloads folder.

Ultimately, I would like to extend the idea to provide the same type/subtype menu system for all files under all folders – a type of summary – but I have not implemented that yet. There are other features in the cooking pot, as well, but I have to get started on some “RL” tasks… like my resume. 🙂

Screencast

I had a problem recording audio, so I ended up typing as narration. Unfortunately, this makes the YouTube one pretty unwatchable, but you can give the “HQ” version a try.

Download

No tarball yet as it’s still extremely rough.
Browse the source here.
Branch the source: bzr branch http://stevenbrown.ca/src/FileListApplet

Install

Update 2009/04/05: Updated install instructions here. (Some people don’t look at the comments….)

Installing will require some manual modifications.

  1. First, make sure you have the following packages (Ubuntu): python-xdg, python-gnome2-desktop, python-gtk2, python-pyinotify
  2. Then branch the source.
  3. Adjust the FileListApplet.server file’s location to wherever you keep it.
  4. Then copy FileListApplet.server to /usr/lib/bonobo/servers/.
  5. Restart the bonobo-activation-server. killall bonobo-activation-server
  6. Add it to the panel like other applets.

Update 2008/12/05: Added a couple screenshots.

GNOME 3.0 Ideas (Intelligent Desktop)

This is based off of a Summer of Code application I made in 2007, titled “Intelligent Desktop.” Recent discussions have reminded me to at least blog about it. And given my current employment status, I have the time. 🙂

Note: You may also be interested in File List Applet filelistapplet.

Messy Desk

The desktop – this gigantic area of screen real-estate – is a mess. Some people use their desktop to dump random files that they’re working on, or have recently downloaded. Others work tirelessly to keep the pretty background picture visible with minimal icon clutter. Still others find the Desktop useless because it fills up with icons too easily. In the Nautilus Desktop (GNOME’s default), icons can get placed on top of one another either by a bug in placement or simply because there is no space left, which really deters from the usability. Personally, I clump different themed files/folders into the corners of my desktop. When a file is added to the desktop procedurally, there is no obvious place to put it and thus no obvious place to look for it. This is compounded if there is a “hole” in one of my “icon clumps,” in which case the hole may be filled with the new icon making it extremely difficult to locate by both file name and screen location. I recently gave up on having mounted drives displayed on the desktop. Anything dynamic fails miserably as their location changes each time, and sometimes they even end up overlapping other icons. In any case, it seems the desktop requires maintenance to work, when it really shouldn’t.

An Intelligent Desktop would overcome icon clutter automatically and intelligently. It would also be a starting point to looking at potential benefits of a more dynamic desktop view. I’ll explain what I mean by this in a second. This is NOT that silly little notification that your desktop has old/unused icons on it.

Automatically Sorted, Categorized, Updated and Easily Searched

The desktop is a useful place to dump files, but retrieving them is a pain. In fact, browsing the desktop for that particular file (or folder) is a pain without a lot of maintenance. My idea requires an always-visible, on-the-desktop set of UI elements that I will call the Desktop Action Window (DAW). The easiest way to think of the DAW is as a sidebar for the desktop. (Don’t stand up quite yet, sidebar haters.) But rather than the DAW being a collection of meta-information or unrelated widgets, think of it as a controller to the desktop view (formerly just a desktop). Performing actions on the desktop via the DAW simply creates a new view of the desktop. The original/default view that is customized by the user will always be available. If you think in terms of Model-View-Controller, the current desktop is essentially everything. With the DAW, the DAW becomes the controller, the desktop viewing area becomes the view, and the model is partially hidden. The DAW should allow easy management of multiple views of the desktop, some automatic (Images, Movies, Recently Modified), some static (Default, Custom).

And you shouldn’t be concerned about a sizable widget infringing on your carefully chosen background, there are ways around that: the DAW could be hidden when no mouse movement on the desktop occurs (like the controls of a photo slide show), it could be semi transparent until the mouse is over it, it’s location could be customized, etc.

Some quick ideas for different actions in the DAW include:

  • An automatically generated list of types of files on the Desktop. Selecting one of them displays all icons of that type.
  • A text entry for string pattern matching.
  • Ability to easily hide all icons, except ‘always visible icons.’
  • Ability to have custom views displaying only icons that user specifies.
  • Ability to easily open file manager and display all files
  • Some form of icon pager or scrollable desktop view to allow for arbitrary numbers of icons to be displayed per view.
  • Ability to view and manipulate an arbitrary folder, such as Home, in the same way.

Mockups

This is where I stop the prose and leave you with a couple mockups. The “Overflow” view could probably be replaced with “New” or “Recent” for recently modified files. Anytime new files/folders/launchers have been added, the button could be flashing to grab the user’s attention. Better not to alter the default view at all, I think.

Update 2008/12/04: I’ve started implementing what I was thinking about with the automatic view filter as a GNOME panel applet. Check out File List Applet.
