    nm-applet problems (mem leak, behavior, icon etc.)

    Ubuntu 10.10 with latest updates
    manually added ppa:s such as awn-trunk etc

    Acer Notebook (i3 370m, ATI 5470mhd, 3Gb RAM etc)
    Internet con. through Nokia 5630 HSDPA - usb

    I ve noticed the network-manager starting having problems 4-5 days ago when
    I logged in for a usual session having my comp connected to 40#LCD @ 1080p.
    The icon theme (have Faenza Dark as standard) was reverted to gnome standard
    and a new volume icon/controller started in the notification area. So I searched for
    any info I could find and that brought me to nm-applet mem leak info and bugg-
    reports. I logged out from the session and once I logged in all was well. You would
    think so right

    So here is the problem I have.

    1: nm-applet --sm-disable starts at loggin BUT after 6-7h is non-responsive
    eating up massive 250+ Mb of RAM
    2: nm-applet lacks the indicators of signal-strength as it used to have
    3: nm-applet is a part of indicator-applet 0.4.6 (used to be separated in Notification Area 2.30.2)
    * see first 2 attached images

    killall nm-applet works as expected
    Code:
    ~$ ps -ef | grep nm-applet
    root      5229  5164  0 12:02 pts/0    00:00:03 nm-applet --sm-disable
    sudo nm-applet --sm-disable in terminal starts new nm-applet
    as it should in notification area with some messages
    Code:
    (nm-applet:5229): GLib-GObject-WARNING **: invalid (NULL) pointer instance
    
    (nm-applet:5229): GLib-GObject-CRITICAL **: g_signal_connect_data: assertion `G_TYPE_CHECK_INSTANCE (instance)' failed
    * see last 2 attached images

    Now, this way it stays connected and responsive as far as I see forever
    without the mem-leak issue but as soon as I logout the session its all
    back to the state 1.
    What can I do about this?
    I am currently looking at different wm:s and options but I do like my
    gnome the way it is and would like to see a solution to the problem instead of running away from it.

    btw the NetworkManager Applet is v. 0.8.3 and I have tried to disable it
    from the startup applications but it re-enabled it self.

    Re: nm-applet problems (mem leak, behavior, icon etc.)

    Bumping up my thread with additional info...
    My only solution so far to my issue is removing following
    *Indicator Applet
    *Indicator Applet Session
    and only keeping Notification area since nm-applet starts and keeps it self
    active for 7-8h+ (consuming around 50-60mb RAM) is somewhat a step
    forward. Any ideas or help greatly appreciated.

    I do not think that this is a network issue but a Desktop environment issue. Last year I had something weird happening to my desktop. Sometimes on boot up the icons would be different and I would need to re-select my chosen theme.

    When did you last re-install and format the disc? I think that overtime and with the changes (improvements) that come with each upgrade, you get a collection of configuration files that sometimes cause conflicts.

    Last October I re-installed and formatted the Ubuntu partition and the home partition. Now I have enhanced appearance effects. That was something else that I had a problem with.

    I have decided that a clean sweep from time to time is useful. Do not forget to backup everything you want to keep.

    Regards.

    Just thought I'd add that I have the exact same problem and I also happen to use the same theme. No direct solution yet though.

    This is fairly new set-up since december and fresh install of 10.10 so those issues I ve been
    reading about people having from up-grading couldn't be the case here. One another thing
    that comes back in my thoughts is that having this comp running for 2 users (1 with hdmi out-put and another purely native resolution) this problem doesnt seem to involve the later.
    I do have the option of re-install and even try another wm as I mentioned, but being the tech-oriented guy I am, I still prefer finding a solution. Thanks for sharing your experience tho.

    I would think this is an issue effecting a lot of us and there are plenty of bug-reports out there so lets just hope for a "quick-fix" even tho there s no such thing as quick-fix

    Quick fix: install indicator-network, and disable nm-applet. Works for me, but indicator-network is not as user friendly and feature rich as nm-applet.

    Thank you for your reply.
    That is the main bug-report I ve been reading and with your additional info
    from today I have one question. My network-manager-gnome is in deed the
    one from ppa:elementaryart... 0.8.2+git.20101123t161608.f143e76-0ubuntu1
    so what I am asking is how did you downgraded to the default one?
    Will I be able to do the same considering I only have access to one network
    connection and I presume some packages will be needed to download after the
    process of removing the 0.8.2+git version takes place?

    Never mind that - I ve found my way but for those who wonder...
    Open up Synaptic Package Manager and look for network-manager-gnome
    If you want to downgrade it to default 0.8.1+git.20100809t190028.290dc70-0ubuntu3
    the mark the 0.8.2 version then choose Package and Force Version... from the menu.
    Once there select the 0.8.1 version and hit apply...

    I ll be monitoring this and see what it does on my comp. Thanks again Beruic!

    Sounds good. Throw updates at the bug from now on if they are relevant
