 * A [http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=407035 crash] was detected when drag&drop'ing blocks of text and was workarounded in the GTK frontend. I could not reproduce this bug with gtk/dfb libs in gnome svn head, so i think this is related to our heavily patched gtk/dfb 2.8.20 set of libs.

It would be nice for g-i to have some games to help kill time during lengthy install sessions.

Candidates for inclusion need to have a limited set of dependencies, preferable only those that are already included in g-i, use directfb for graphics, eventually using SDL, sound should be optional, and not need more input device than already detected by g-i.

This excludes c++ implemented games linked against libstdc++, or other language whose runtime is not-available in g-i, as well as all those that link with the gnome libs or other such. A preliminary list follows, out of them, icebreaker sounds like a very good candidate. It is only depending on libsdl, easy to understand, using only the mouse and not the keyboard, and not controversial in any way.

Introduction

This is an overview of some of the bugs and issues that presumably will be left open or workarounded only in Etch and that i hope will be fixed later in a point release.

This is no way meant to be an exhaustive list of every bug somehow related to the graphical installer, for a complete buglist see packages [http://bugs.debian.org/cgi-bin/pkgreport.cgi?pkg=cdebconf-gtk-udeb cdebconf-gtk-udeb], [http://bugs.debian.org/cgi-bin/pkgreport.cgi?pkg=directfb directfb], [http://bugs.debian.org/cgi-bin/pkgreport.cgi?pkg=libdirectfb-0.9-25-udeb libdirectfb-0.9-25-udeb], [http://bugs.debian.org/cgi-bin/pkgreport.cgi?pkg=libgtk-directfb-2.0-0 libgtk-directfb-2.0-0], [http://bugs.debian.org/cgi-bin/pkgreport.cgi?pkg=libgtk-directfb-2.0-0 libgtk-directfb-2.0-0-udeb], [http://bugs.debian.org/cgi-bin/pkgreport.cgi?pkg=rootskel rootskel], [http://bugs.debian.org/cgi-bin/pkgreport.cgi?pkg=rootskel-gtk rootskel-gtk]

Architecture independent issues

Per-architecture issues

We're trying to inventory bugs affecting the g-i on a per-architecture base, architectures considered here are i386, PPC, AMD64 .

i386 specific

  • For historical reasons the vga16fb module is still loaded even if a framebuffer device is already provided by vesafb: this forced us to check that DirectFB actually accesses the framebuffer device provided by vesafb , better would be not starting at all two fb devices concurrently (this also wastes little memory). [http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=401685 #401685]

  • Some popular video chips, like intel i810, are not supported by the vesafb framebuffer module and hw-specific modules are not available in the installer, so we cannot currently support those chips. We need to either build into the kernel or provide as loadable modules hw specific framebuffer modules, and load them on the base of the found hardware [http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=405737 #405737].

AMD64 specific

Proper fix requires adding that library via an udeb, or removing pthread_cancel() calls from DirectFB source code.

PowerPC specific

  • On PPC the framebuffer device has a fixed size that cannot be set at boot like it's done on i386, so the GTK frontend should adapt itself to go "fullscreen". [http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=401693 #401693]

  • DirectFB's linux_input input module seems particularly willing to crash on this architecture, and as a result we had to selectively disable such module basing on experiments on on various PPC boxes.

Read also this long [http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=342053 thread] about the g-i on PPC machines.

Ideas for future development

Porting

The graphical version of the installer is currently available for Intel x86, AMD64 and PowerPC. The PowerPC port [http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=341597 needs work] to get different types of system correctly supported. Other architectures the graphical installer could be ported to include Sparc, Alpha and HPPA.

Fonts

For font information, please see ["DebianInstaller/GUIFonts"]

Usability

  • Interface should adapt itself so that text blocks are never too wide for optimal readability.
  • Improve accessability (for the visually handicapped). One way to do this is to [http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=339735 support different themes] (color schemes). (Note: should not lead to a major increase in initrd size.)

  • Alternative (graphical) ways to start a shell or browse log files.
  • Interface design.
  • Create custom plug-ins for cdebconf to improve handling of some dialogs and make optimal use of possibilities offered by the graphical environment.

Interface design

Most of the work on the graphical side has been done by Eduardo Silva. He has set up a [http://www.geocities.com/jobezone/d-i_gtk.html webpage] with images he designed and some comments about possible future changes.

Games

It would be nice for g-i to have some games to help kill time during lengthy install sessions.

Candidates for inclusion need to have a limited set of dependencies, preferable only those that are already included in g-i, use directfb for graphics, eventually using SDL, sound should be optional, and not need more input device than already detected by g-i.

This excludes c++ implemented games linked against libstdc++, or other language whose runtime is not-available in g-i, as well as all those that link with the gnome libs or other such.

It is only depending on libsdl, easy to understand, using only the mouse and not the keyboard, and not controversial in any way.
