2 HEPiX X11 Desktop Project: Pros and Cons Author: Víctor Robles Forcada, IT/DIS/OSE With the collaboration of: Germán Cancio Meliá Lionel Cons Philippe Defert Presented by: Philippe Defert

3 Presentation Plan • Part 1: Modern desktops: GNOME and KDE • Part 2: Deployment issues • Part 3: Questions, general discussion

4 PART 1 MODERN DESKTOPS GNOME and KDE

5 Why not only a basic X11 environment? • Most X11 applications have important shortcomings: • Application Interoperability is too hard • User Interface is inconsistent and of unequal quality • Modern desktop environment brings the "glue" • Drag & Drop, Session Management, etc... • Consistent "look and feel" • Unified Help System • Easy dialog based desktop configuration • Common application development framework (-> MFC) • Compound document framework (-> OLE) • New exciting possibilities: • Hundreds of new applications (including Office) • Powerful application development environment

6 KDE and GNOME (reminder) • K Desktop Environment • KDE is a "complete desktop environment that try to make linux accessible to everybody" • At present KDE and for the first half of the next year KDE 2.0 • GNU Network Object Model Environment • AIM: "GNOME Intends to build a complete, user-friendly desktop, similar to CDE or KDE, but based entirely on free software" • At present GNOME

7 What is new since April? • New Qt 2.0 for KDE 2.0 with QPL License • GNOME Documentation (still not enough) • Lots of new applications • Component model: now in the basis. • Agree (KDE 2.0 & GNOME ): • Session Management protocol (XSMP) • Drag & Drop protocol (XDND) • Window Manager Specifications • Storing part of Desktop Information • Sound System (near future -aRTs-) • Still disagree: • CORBA (common IDL, server activation, etc.) • Printing • Help System • Directory layout, rc files, mime types, ShortCut keys

12 Use of CORBA (reminder) • Used for implementing a component based programming framework (OLE) • As a general IPC mechanism • Exporting an application's API (IDL files) • Scripting (macros and Visual Basic) • Define system services • KOM/OpenParts and Bonobo (OLE2 and ActiveX)

13 Applications (reminder) • Both desktops have hundreds of applications. • Some useful, some buggy. • All kinds of applications: Mail clients, network, sound, development tools, games, etc. • Perhaps in a near future we will forget our 'standard' X applications • See the applications table

14 Office Suites

15 PART 2 DEPLOYMENT ISSUES

16 Choosing a Desktop • Only one desktop or both ? • Main criteria for the selection: • Stability • Efficiency • Usability (ease of use, customization,...) • Applications • Office Suite • Technology • Users will have the last word.

17 Desktop Customization • Central management avoids support nightmare • Things to customize: • Icons on the desktop (home directory, trash bin, applications...) • Start up applications (mxconns) • Icons on the panel (netscape, xterm, phone book...) • Applets on the panel (clock, CPU load...) • Start Menu (like NICE?) • Specific programs (E.g. Tokens Applet) • Similar to HEPiX X11, NICE

18 Needed local Programs • Interface to local print services • Managing Start menus • Applets (token watch, phone book,...)

19 Estimations

20 More Information • Web pages: • • • • • •

21 PART 3 HEPiX IN THE GAME ? SOME DISCUSSION !

22 Usage • Who is using KDE/GNOME now ? • Which site is planning to support modern desktops ? • Which site plans to deploy GNOME/KDE ?

23 Deployment • Which site plans to have centralized deployment of a desktop ? • Which site would like to have a centrally managed desktop environment for his users ? • Would it be useful to organize an HEPiX collaboration about desktops to answer the questions: one or both, which customization, when, which OS, etc... ?

24 Development • Who is planning development in these desktop environment ? • Encourage or discourage experiments to do so ?
