Up to here everything worked ok for me.

I have not had the sound problems, but the 'hang' problem I can
reproduce in some programs with EXACTLY the same symptoms:

cd /usr/local/allegro-3.9.38
setup/setup

(nice small setup X-window appears.)
-> select autodetect -> open sound system for both midi and sound. Ok -> hangs in the first screen.

-> select test right away (no autodetect): sound plays nicely, both midi and wav. Ok (back to main screen): hangs.

cd demo
demo
(select graphics screen: select autodect, 640x480, dirty rect)
   -> demo game works in 640x480 X-window.

try again for different graphic modes: 
autodetect fullscreen, 640x480: Can not set video mode.  
other resolutions (ones I've defined in X config): 
same problem, but an extra message: Can not grab mouse.

autodetect windowed: works.

dga 2.0: (nice! detects my defined resolutions..): can not open framebuffer.
try again as root:
this gives VERY fascinating results: I get 2 'semi-windows' projected next to eachother, each using half of the screen, just like one half of the pixels is projected on the left half and the other half on the right half of the screen. Both halves look 'fuzzy', with funny colors.
dga 2.0 soft: same results.

dga 1.0 (as root): DGA 1.0 is required. Apparently I'm missing something here, either in X or in allegro.
dga 1.0 windowed: same result.

X11 fullscreen: (normal user): 
Error setting 8bpp graphics mode
Can not grab mouse
as root: same problem

X11 windowed: everything works.

cd ../tests
test

everything seems to work (except those same graphics modes), but when
I try the scrolling test, the program hangs just like the setup program.

For me trouble has only started at .38: .37 worked like a dream, *also
the fullscreen modes*! 

I've tested all this using X 4 (.003?), xdpyinfo reports
version number:    11.0
vendor string:    The XFree86 Project, Inc
vendor release number:    4003

windowmanager is WindowMaker

Linux hoefnix.alma.icce.rug.nl 2.4.4 #6 Sat Jun 30 15:34:40 CEST 2001
i686 unknown

videocard is a RIVA TNT1

No other applications running that are doing strange things. Both
sound and graphics work fine for applications (and also for *some*
settings for allegro .38 programs...)

Allegro was built with no special configure options, just enabled
debug and profile library, and pentium optimizations.

I'm really interested if anyone has an idea about these problems,
because like this version .38 is broken for me. If I can be of help
with further tests, let me know by email, I'll happily try things out.
