Bug Description

if you log in directly on an ltsp server after having used a thin client on the same server with the same account, the login hangs, apparently gnome-session cant handle a virtual alsa device that has no backend connected, a workaround is to use the ltsp-sound script to unset the pulse config if no thin client is used and pulse isnt installed on the server

The fix is to replace /etc/X11/Xsession.d/80_ltsp-sound with the following script, this should go into feisty-updates:

if [ -n "$LTSP_CLIENT" ]; then
        /usr/bin/asoundconf set-pulseaudio
else
    if [ !$(which pulseaudio) ]; then
            /usr/bin/asoundconf unset-pulseaudio
    fi
fi

Comments about SRU:

* Please get this fixed and tested in gutsy first.
* The patch (r520) should be polished a bit: [ !$(which pulseaudio) ] => ! type pulseaudio >/dev/null 2>&1
  This avoids unsafe quoting, the lack of a test operator, and avoids a subshell.
* The changelog (r521) should not talk about 'added fixed script', but explain the change and the impact.

No visible progress on this, so I unsubscribed ubuntu-sru for now. Please re-subscribe when this is fixed in gutsy and my other points in comment 3 are solved. Thank you!

This also seems to be quite serious and simple to fix, so let's get it into Tribe 4.

Ubuntu Feisty Fawn is no longer supported, so a SRU will not be issued for this release. Marking Feisty as Won't Fix.
