Hi Jim,
Hi, I’m having some trouble with tuxpaint, tuxmath and tuxtype on qimo 2.0(all updates installed) but problems started at initial >>install. In tuxpaint i can use the app but when i go to quit the app freezes and will not let me save or quit. If i run tuxpaint --nosound >>it runs without problem.(sound is working on the machine through alsa mixer) When i run tuxmath and tuxtype the screen starts >>flashing to a black screen then back to the app. Not sure where to start with this. Hope someone can help.
Hey Jim. This is probably a compatibility problem with a
combination of SDL, ALSA and PulseAudio.
Basically, you can either (1) remove PulseAudio (what I’ve done
on my Ubuntu 9.04 system, and it behaves a LOT better), or
(2) install the PulseAudio backend for SDL (versus ALSA, which
then talks to PulseAudio). On Debian, for example, this package
does it: libsdl1.2debian-pulseaudio
For more, see:

If this doesn’t turn out to be the issue at hand, or the
suggestions don’t fix it, please let us know! Good luck!
thanks david…here are some logs i saved(attached). one is strace for tuxmath and tuxtype and one is the error left when i run the >app from a terminal window…thank you again!!! anything that might help out let me know
So far I haven’t been able to reproduce the problem. Actually, I
don’t have an Ubuntu install at the moment - I had forgotten that I
had wiped my laptop that had 10.04 and reinstalled with Debian Sid.
I downloaded the Qimo 2.0 live CD and tried it on the Dell laptop, and
all three of the tux4kids apps ran fine.
Looking at your log files, I suspect it really is a sound
system-related problem, based on the following line:
ALSA lib pcm.c:7245:(snd_pcm_recover) underrun occured
Googling for this gives a bunch of forum posts about similar problems
others have seen, but I haven’t (yet) found the solution. I’m hoping
that this scenario will ring a bell with someone on the SDL dev list,
whom I have cc’d.
Best,
