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 exaustive 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=rootskel-gtk rootskel-gtk], [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 indipendent issues

  • Input is not handled in UTF-8 mode, some letteres cannot be correctly typed. [http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=401296 #401296]

  • Support dor dead keys was added in DFB post 0.9.25, but GTKDFB does not handle deadkeys anyway, so backporting the DrectFB patch is useless ATM [http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=394871 #394871]

  • Touchpad support in linux_input was added to DFB in CVS and then backported to 0.9.25-5 via a patch i wrote; Ville Sryala produced an updated, better, patch which unluckily crashes on some systems and hence we weren't able to include in our sources.

As we want to give best support possible to laptop users Ville's patch should be fixed and bacported in our sources. [http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=400579 #400579]

  • Diagnostic tool dfbinfo is now provided by libdirectfb-udeb, later we should move it to a specific udeb, possibly with the df_input tool [http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=390437 #390437]

  • A cdebconf-gtk-entropy plugin is needed if we want to be able to install on encrypted volumes with the the GTK frontend too.

Per-architecture issues

We're trying to schematize 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]

AMD64 specific

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

PPC 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 particulary 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.
