'Twas brillig, and Halim Sahin at 23/12/09 14:26 did gyre and gimble: > Hi Col, > 1.

GDM runs under the gdm user and starts it's own PulseAudio process. This can be easily used to do the reading of the login screen. I'm not familiar with how screen readers work but that software should also be launched as the gdm user. When a real user logs in, gdm's PA and screenreader services will die or be suspended and the real user's PA and screenreader service takes over. > 2.

I don't see any reason why speech-dispatcher needs to run as it's own user. Why not just run it as the user who is actually using it? At the end of the day the fact that a uid "speech-dispatcher" can access a users' sound is disturbing. If that user is compromised they can evesdrop on your user which is not very nice. > But it introduced problems wich should be fixed. I agree it has introduced problems for certain applications but just because something has changed, it doesn't mean that PA needs to support an obsolete, weird or insecure way of working that was permitted in the past. > Your given examples are related to x-sessions. > Go one step back. > gdm starts and the screenreader->speech-server (before login). > If pulseaudio starts at this time, it would use gdm uid.

After login the gdm user is no longer permitted access to the audio devices and the logging in user take over control, starts their own PA etc. It all works nicely. Hope this helps.
