I enabled telepathy-salut logs by adding these to /etc/environment (note that changing debug file does not work anymore):
G_MESSAGES_DEBUG="all" SALUT_DEBUG="all" SALUT_LOGFILE=/home/olpc/salut.log I see a lot of activity when I connect to an access point (or to modified ad-hoc network), but I when connect to a normal Sugar ad-hoc network, I see this in the log: ... (telepathy-salut:728): salut-DEBUG: gabble_capabilities_finalize: 0xab108 (telepathy-salut:728): salut-DEBUG: salut_connection_finalize: Finalizing connection (telepathy-salut:728): tp-glib-DEBUG: no connections, and timed out tp-glib-Message: Exiting There is when the salut exits. I tried forcing it to not exit by adding this to /etc/environment: SALUT_PERSIST=1 In that case, when I connect to the normal Sugar ad-hoc network, I see the "time out" message and the process keeps running, but no activity is logged until I re-connect to an access point or modified ad-hoc. So basically, even if the process keeps running the issue persist...
