I did an upgrade from Gnome 3.0 to 3.2 last Thursday, and while Gnome 3.0 worked very well for me, 3.2 has been a disaster.
- The most annoying problem was that I lost networking. Nm-applet wasn’t running, and I received the following error message when manually trying to start it:
** Message: applet now removed from the notification area
(nm-applet:9888): libnotify-WARNING **: Failed to connect to proxy
** (nm-applet:9888): WARNING **: get_all_cb: couldn’t retrieve system settings properties: (25) Launch helper exited with unknown return code 1.
** Message: applet now embedded in the notification area
** (nm-applet:9888): WARNING **: fetch_connections_done: error fetching connections: (25) Launch helper exited with unknown return code 1.
** (nm-applet:9888): WARNING : Failed to register as an agent: (25) Launch helper exited with unknown return code 1
^C Message: PID 0 (we are 9888) sent signal 2, shutting down…
A quick Google check showed me that this was due to Network Manager itself not starting. NM refused to start manually. Sorry, but I forgot to save the error message I received. Downgrading to the version of NM in the 3.0 repository made everything work again.
- I’ve also not been able to get sound in Banshee and Totem, and I can’t hear the test sound through the Gnome System Configuration tool either. Non-Gnome apps work fine though. I can hear sound in Firefox and Audacious. I did an upgrade of gstreamer packages to those in the Gnome 3.2 repository, as they didn’t upgrade intitally for some reason, but the problem still persists.
When I start Audacious, I get an ALSA error message:
snd_mixer_find_selem failed.
Audacious works, though, after dismissing the message box.
I also get the following error message when I use sox:
ALSA lib pcm_dmix.c:1018: (snd_pcm_dmix_open) unable to open slave
play FAIL formats: can’t open output file `default’: snd_pcm_open error: Device or resource busy
I wasn’t receiving either message in 3.0.
I also sometimes have to restart Firefox to hear sound. It mysteriously stops working at times.
-
The following extensions crash gnome-shell: Window Navigator, Alternative Status Menu and Workspace Indicator. The Dock extension doesn’t work at all. The dock doesn’t show up when it’s activated.
-
Gnome Tweak Tool doesn’t show in the applications menu. The desktop configuration file doesn’t exist.
-
Also, when opening Nautilus, the cursor stays busy for about five seconds. It works fine otherwise, but it’s an annoyance.
Does anyone have any suggestions? I haven’t seen any reports of these issues from anyone else. I’m using 11.4 64-bit.
