GNOME Bugzilla – Bug 589207
Icon disappears
Last modified: 2010-04-04 18:56:41 UTC
Sometimes, after I restart my computer (Dell Mini 12) the NetworkManager icon does not appear, and since I am new to the Unix/Linux/Ubuntu family, I really have NO clue how to connect to the internet without this NetworkManager icon. When this happened for the first time, I looked onto the "Add a Panel" on the task bar, but I could not find the application. So now, I just restarted the computer again (usally three times) until the icon appears. Then it is all good.
This bug is confirmed by several users of ubuntu 9.10. The workaround is to remove and add again the "Notification area" from the top panel https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/446093
You should be getting some crash logs from apport when the applet goes away; we'll need those to determine where the icon is dying. Alternatively, you can do the following in a terminal: killall -TERM nm-applet gdb nm-applet run and wait until the applet crashes (gdb will say something like "received signal SIGSEGV") and the type "backtrace" and paste the output into this bug.
This bug is now fixed
Closning as OBSOLETE as per last comment.
