I've installed OpenBSD 4.6 on

hw.vendor=Apple Computer, Inc.
hw.product=PowerMac3,5
hw.physmem=1073741824
hw.usermem=1073729536

The OS runs fine, however, certain X desktop environments seem to not
want to cooperate.

Of the 3, KDE seems to run the best, however, the audio is broken.
When I first login, the login wav starts playing but then after 1
second starts playing noise.  It would be nice to have audio (maybe
KDE can somehow play through aucat?).

Gnome looks really great, but after a few seconds becomes unresponsive
to key clicks or keyboard typing.  Only way out is ctrl-alt-backspace.

XFCE also starts up fine, but after a few second also becomes
unresponsive much like gnome and needs ctrl-alt-backspace.

Is there something wrong with these X environments on powerpc?

WindowMaker works as always, but I wanted to try out other options. :-)

Here is a dmesg:

I noticed that running on a PowerBook with xdm bad things happen. I  
can run mine reliably when using startx. Don't know about audio though.


[ message continues ]

That sounds like the thing mentioned in the second parapgraph of
/usr/X11R6/README


[ message continues ]

Yes, this looks very relevant, thank you.

[ message continues ]

Yes, this is precisely what I have discovered.  xdm/gdm/kdm do not
work well at all, however,
startx does work for most WMs except for Gnome and XFCE.  KDE works
but lacks functional audio.

Thanks.

p.s. here's another shared whiteboard (or 2):

if you have a tumbler(4) device, there's patches on tech@ to test ...

someone with the devices with the problems needs to do more to figure
out what exactly the problem is.  "lacks functional audio" is extremely
vague.  does audio work otherwise?  for example, can you play files with
aucat on the console?  if so, do other players work, on the console?
if so, does artsd itself work?  did you check that your audio

Yes, this shows up in the dmesg I pasted:

Yes, it was a bit too vague.  Audio in the general sense works fine.
I can play things with xmms,
aucat and other applications.  I tried to run aucat -l and while artsd
does use the
audio server, it still does strange things.  When KDE first comes up,
it tries to play the
startup music and about .5s of music comes out, then it switches to
noise (like someone
sent raw binary data to the audio device).

I haven't been able to do much else in the way of  testing
KDE because nothing else in KDE seems to be working.  If I click on
the K menu, there are
literally no applications (even though I have plenty of KDE
installed).  If I try to bring up
the KDE Control Center, the application never appears.  Running it
from an xterm actually
does run it, and I get the following output:

kcontrol: WARNING: No K menu group with X-KDE-BaseGroup=settings found
! Defaulting to Settings/

Which is not surprising given that there are no menus at all with any
applications to speak of.
There are also no options at all in kcontrol.

If I try to run kmenuedit I also get strange errors:

kmenuedit: WARNING: Could not read
/home/luddy/.config/menus/applications-kmenuedit.menu

And there is nothing in the dialog once it starts.  I searched for an
appliations-kmenuedit.menu
in /usr/local and couldn't find one either.

Is it possible I'm missing a package:

kdeaddons-3.5.10p1  K Desktop Environment, addons
kdeadmin-3.5.10     K Desktop Environment, admin tools
kdeartwork-3.5.10p2 K Desktop Environment, additional artwork
kdebase-3.5.10p2    K Desktop Environment, basic applications
kdeedu-3.5.10p0     K Desktop Environment, edutainment
kdegames-3.5.10p0   K Desktop Environment, games
kdegraphics-3.5.10  K Desktop Environment, graphic applications
kdelibs-3.5.10p0    K Desktop Environment, ...
[ message continues ]

It would appear that I missed the following instruction from the
kdelibs package:

Install notice:
To use the KDE3 layout as default for the applications menu, as root:
 ln -sf /etc/xdg/menus/kde3-applications.menu \
        /etc/xdg/menus/applications.menu

So at least now KDE is working.  Now I can continue trying to find out why
KDE
is producing noise for its actions (login, logout, error dialog, etc.).

Now that KDE is working, I can answer some of these additional
questions.  artsd is working.
All other audio configuration appears sane.  Apparently the default
sounds for KDE are configured
to play a .ogg file.  For example, login plays KDE_Startup_3.ogg,
logout plays KDE_Logout_3.ogg
and an error dialog plays KDE_Glass_Break.ogg.  So for some reason,
KDE is unable to play
these .ogg files (they come out as noise).

libogg-1.1.3        Ogg bitstream library

Is installed.  So who knows...  At any rate, I reconfigured KDE to use
.wav versions of the files
and now they play just fine.

Thanks.

[ message continues ]

well thank you for greatly narrowing down the problem.  can you play
other OGG files with artsplay?  hmm.  arts seems to think my 44.1
kHz OGG files are 48 kHz - on i386.  start artsd like so: 'artsd -l 0',
then watch what it prints when you play a file with artsdplay in a
different terminal.

wasn't there a similar issue with OGG files with mplayer?  is libogg/
libvorbis broken?

I've been unable to follow misc@ and ports@ for the past few weeks.
So, I apologize for the proverbial dead horse (provided s/he's dead),
but I will point to these threads that started a while back concerning
ogg and mplayer (via devede) . . . I suspect this is what is being
referred to.

Apparently not.  I started artsd with debug options and when I try to
play with artsplay I just get static noise.  Here is artsd output (not
sure if it will help):

[artsd: 23458] SoundServerStartup <-- released lock
UnixManager: got notifyIO
socketconnection created, fd = 11
search playobject, extension = ogg

socketconnection created, fd = 11
search playobject, extension = ogg
creating xineAudioPlayObject to play file
/usr/local/share/sounds/freedesktop/stereo/battery-low.ogg

Each of these just produced noise.  However, when I play a .wav file,
I get a different output from artsd:

UnixManager: got notifyIO
socketconnection created, fd = 11
search playobject, extension = wav
creating Arts::audiofilePlayObject to play file

arts is a plugin architecture.  when you have kdemultimedia installed,
it'll use the xine plugin to play OGG files.  the OGG plugin that
comes with the arts package prints the sample rate.

most KDE apps use artsd, which can run on top of aucat.  if you're
running aucat server it should just work (artsd starting automagically
and playing through aucat, that is).

that being said, I have no idea how well the macppc i2s audio devices
actually work or how well artsd (and really, KDE as a whole) works on
macppc.

I have a PowerMac4,1 and am noticing the same.

If you startxfce from within fvwm2 session, it becomes immediately obvious that this is a focus issue. In gnome and xfce focus goes somewhere offscreen at the first keypress. No idea why and how to fix.
