Network Manager failure after reboot

[dallingham]

I have a new system76 pangolin that came with 10.04 installed. NetworkManager has been working fine for several days. After a reboot today, the nm-applet no longer displays, and I can no longer connect to a wireless network. I have been able to restore internet access on the wired connection by editing the /etc/network/interfaces file.

NetworkManager is running, and doesn't seem to be giving any error messages. Syslog shows:

syslog.1:May 16 10:09:26 gromit NetworkManager: <info> WiFi enabled by radio killswitch; enabled by state file
syslog.1:May 16 10:09:26 gromit NetworkManager: <info> WWAN enabled by radio killswitch; enabled by state file
syslog.1:May 16 10:09:26 gromit NetworkManager: <info> (wlan0): driver supports SSID scans (scan_capa 0x01).
syslog.1:May 16 10:09:26 gromit NetworkManager: <info> (wlan0): new 802.11 WiFi device (driver: 'iwlagn')
syslog.1:May 16 10:09:26 gromit NetworkManager: <info> (wlan0): exported as /org/freedesktop/NetworkManager/Devices/0

nm-applet refuses to display, so I cannot connect to any wireless APs.
Killing nm-applet and restarting it displays:
dona@gromit:/var/log$ pkill nm-applet
dona@gromit:/var/log$ nm-applet
** (nm-applet:2965): DEBUG: old state indicates that this was not a disconnect 0
** (nm-applet:2965): DEBUG: old state indicates that this was not a disconnect 0

** (nm-applet:2965): DEBUG: going for offline with icon: notification-network-disconnected
** (nm-applet:2965): DEBUG: going for offline with icon: notification-network-disconnected


But still, nothing displays. The card is alive. iwconfig reports:

wlan0 IEEE 802.11abgn ESSIDff/any
Mode:Managed Access Point: Not-Associated Tx-Power=15 dBm
Retry long limit:7 RTS thrff Fragment thrff

Any help would be greatly appreciated.
Thanks.

I know there is a command that will rebuild your panel and applets, but I don't know what it is offhand.

One temporary solution might be to create another account and see if the applet comes up when you log into that.

[dallingham]

Logging as another user works. The other user has the nm-applet in the panel, and I can connect to the access point.

I tried deleting the .gconf and .gconfd directories to try to restore the panel to an initial state. Apparently this wasn't the right thing to do. I get a clean panel, but nm-applet does not display. Checking ps, nm-applet is running. If I kill it, and start a new copy, it still does not display.

Deleting the panel and creating a new panel seems to have solved the problem. I did the following:

gconftool-2 --shutdown
gconftool --recursive-unset /apps/panel
rm -rf ~/.gconf/apps/panel
pkill gnome-panel

Let me know if you figure out how to fix this. I had my power icon disappear, so that the only way I could log out was to hit control alt delete and then reboot. So I fixed that problem and now my sound applet is gone and I can't adjust my volume.

The Gnome panel in 10.4 is clearly screwed up, and I hope the devs can fix it soon.

EDIT: Thanks, I'll try this.

Hey that worked, thanks!

I will have to keep those commands handy for the next time this happens.

Thank you
