I upgraded a Ubuntu system from 11.04 to 11.10 via
Now some things does not work as before.
For example now, my user needs to be part of the
scanner group to be able to use
xsane etc. - with
< 11.10 this apparently was not necessary.
To be able to use
nm-applet again (for wired networking) I needed to add the user to the group
netdev after the upgrade.
But WLAN management still does not work via NetworkManager -
nm-applet just does not display any wireless devices.
In the logs there is:
NetworkManager wlan0 deactivating device reason managed
But why it is suddenly managed?
/etc/network/interfaces and it does not contain any
/etc/NetworkManager/NetworkManager.conf just contains:
[main] plugins=ifupdown,keyfile [ifupdown] managed=true
Is there some other group the user needs to be part of? Or what else could be messed up after an upgrade?
Manually connecting to a WLAN-AP via wpasupplicant and dhclient (after stopping NetworkManager) works perfectly fine.
Edit: Btw, this Ubuntu system is a little bit non-standard:
wdmis configured as display manger instead of
- as window manager I use
