[Bug 1347272] Re: Several applications appear irresponsible after communicating with DBus

  Thread Previous • Date Previous • • Thread Next 
** Description changed:

- I seem to be hitting transient DBus communication problems after a fresh
- install of Xubuntu 14.04 amd64 on my Thinkpad W510 with the latest
- nvidia binaries from the Ubuntu repos. Here are the related bugs.
- Sometimes rebooting fixes things for a while. If I understand correctly,
- at least one of the bug reports (Bug #1314782) suggests a race condition
- is to blame:
+ ************
+  ROOT CAUSE 
+ ************
  
- Bug #976638 (pkexec does not find any authentication agent)
- Bug #1193236 (Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-*)
- Bug #1239014 (xfsettingsd unable to daemonize properly when overlay scrollbars are activated)
- Bug #1048805 (xfce4-appfinder launches very slowly)
- Bug #1314782 (multimedia keys don't work when xfce4-volumed is run in daemon mode)
+ Several programs in Xfce have a daemon mode call gtk_init() before
+ fork()ing.
+ 
+ This is unsafe, and when it goes wrong this will typically manifest as
+ the daemon hanging shortly after forking, and appearing to simply do
+ nothing at all.
