Since the latest update in Ubuntu 10.10, the nm-applet has started doing some strange things. I boot up the PC, all is fine, internet works, etc... but after a period of time, approx and hour, the nm-applet menu in the Gnome panel fails to respond. when I click on the icon, the menu appears, all looks well, but when I select any option, eg DISCONNECT, nothing happens. Even the VPN sub menu disappears (no triangle to select the menu.) However I do not lose the network connection...
If I Run this script:
killall nm-applet
/etc/init.d/NetworkManager restart
nm-applet
all returns as normal, for a while... weird?
i tried uninstall/reinstall... I even reinstalled Ubuntu, but once the latest updates are applied this issues arises...
Any help?
Certain sources (notably Elementary Desktop's PPA) have a version of network-manager-gnome which is newer than the one in the canonical maverick repository. A fix has been issued for Natty, but is not in the Maverick repos yet. So Ubuntu sees the newer version in elementary-desktop, uses that instead of the canonical one and, hence, the bug.
The solution is to roll back the version of network-manager-gnome to the 0.8.1+git.20100809t190028.290dc70-0ubuntu3 from 0.8.2+git.20101123t161608.f143e76-0ubuntu1
This can be done from synaptic by searching for network-manager-gnome and then clicking 'force version' in the package menu and selecting the 0.8.1 version.
No need to force it anymore, that have taken 0.82 out. So just downgrade, no need to lock.
