Ubuntu :: Network-manager Disappeared And Won't Come Back
Feb 5, 2011
For some reason, I can't get network-manager to appear on the task bar so that I can edit the connections. Also, network manager doesn't appear in system/prefs menu. if I try typing at the terminal 'sudo nm-applet" it says "An instance of nm-applet is already running. ** (nm-applet:9074): WARNING **: <WARN> constructor(): Couldn't initialize the D-Bus manager." If I inspect the system | preferences | startup apps , network manager is selected with the command "nm-applet --sm-disable".
I can see "network-manager" shown in /etc/inid.d but "sudo network-manager" gives "command not found". Anyone know what I have to do to get it working ? Uninstalling and re-installing hasn't worked. I have tried installing Wicd and that shows Lan & wireless connections ok but it *doesn't show my usb data-dongle* which I've just got working using the very useful application UsbModem_Switch by Draisberghof .
So the workaround for me is to call that connection manually ( if I need to use the usb data-card dongle ) with the command "sudo usb_modeswitch -W -c /etc/usb_modeswitch.d/0471:1210". However, if I can get the network-manager applet thing to show up and use that it would be easier. Or is there a better alternative to Wicd which can handle usb data-card modem connections ?
The network manager applet has disappeared from my top panel so now I cannot see what local wireless networks are available. I just came from the library and was unable to connect to their wi-fi because the computer wasn't trying to detect it. All I have is a network connections applet that seems fairly useless as it just gives me info on networks I've used in the past and not on any currently available networks.How do I get this Network Manager back and functioning?
Yesterday while trying (unsuccessfully) to get a new Bluetooth dongle set up I lost the network manager applet. When I rebooted, after giving up on Bluetooth in Ubuntu, I had no way of connecting to my wireless network. In command line (iwconfig & iwlist scan) I was able to see the wireless router. So the wireless card is working correctly. How do I reinstall the network manager applet? Oh even when use a wired connection to the router there is no connection.
Its disappeared before and its gone again> Last time this happened there was a root input which solved the problem but did not take a note of it and cannot find it through google this time Basically left my Linux Acer Aspire One and when I returned to it, connection manager had disappeared and cannot get it back.
I had trouble connecting to a wireless network with openSUSE, so I tried the YAST network manager to see if that fixed it. Not only did it not fix it, but now I cannot connect to any network, wired or wireless. I tried to open the default network manager and it said "Network management disabled". How do I re-enable it?I also have set YAST settings back to their originals with no luck.
I was setting up my internet connection in Ubuntu 10.04, while I had to reboot.After the reboot Network icon in the top-right corner was disappeared! Really, I can't understand why.I tried to open synaptic, totally remove network-manager and network-manager-gnome and then I tried to reinstall them. After the reboot, still, there wasn't Network icon.I tried to press ALT+F2 and insert "nm-applet --sm-disable" but nothing happends.
I tried to right-click on upper-toolbar and then to go on "add panel" but I can't find out network manager (or similar).If I write on my terminal "sudo nm-applet" it says that there's already an nm-applet running but where? And how can I open it?On System/Administration/Network Tools (I don't know if this is the exactly translation...) all network parameters are 0 such us 0.0.0.0 on IPs. Of course internet connection does not work!How can I restore Network Manager?
Im using ubuntu 9.04. The network manager (at least thats what i think its called, the thing managing network connections that usually resides on the panel in the upper right corner where you can check available connections, log in to VPN etc) has completely disappeared, i dont know what i have upgraded, i usually just click and download all upgrades..Ive tried to re-add it to the panel but i cant even find it there.
I am using Ubuntu 10.04 Lucid Lynx 32 bit version alongside my Windows OS.I wanted to enable my DHCP configuration in my modem.So I did what was to be done from Windows and when I switched to Linux, I found DHCP enabled connection not working in Linux and also the network manager icon had vanished from the systray.I have now switched off DHCP and wanted to revert back to my original settings but still no network manager icon is there.
I updated my FC10 just a day back. The problem is that Netwrok Manager has disappeared. And in spite of re-installing it, it doesn't appear on the panel when i enter 'NetworkManager' as root in the terminal.I have a USB modem right now. Update was made through a broadband connection. Ethernet works perfectly well but this USB modem of mine doesn't work at all. And I have to use USB not Ethernet.
I have assigned ip address to laptop by editing /etc/network.interfaces. From next reboot the Network Manager Applet which was present on right hand upper corner, disappeared. I wonder why? This has happened with 9.04, 9.10 and now in 10.04. Another question is, are Network Manager settings (ip) and /etc/network/interfaces do correspond to same thing or not? As I have narrated above, since network manager applet is no more visible how to see the physical network cable connectivity status (as we do in windows xp)? (is there any other app of such kind or what?)
I was attempting to move the buttons on my panel and ended removing my network manager (did it by right clicking it and selecting "remove from the panel"). Now all i want is to put it back but i don't know its command nor where it is to use the "add to panel" feature. Anyone knows how to put it back?
The Volume control and network manager icons are not visible in the notification area.. I sure its has nothing to do with Add to panel-->Notification area....beacuse the notification area is already there.. but the icons are not visible the only way that I can make the visible is by typing code...
for volume control.. Only then they become visible in the notification area
Both, the network manager and volume control are mentioned in the "Start-up programs"
I'm running Kubuntu 10.4. My problem is that Network Manager keeps defaulting back to Auto eth0. I have created a new wired connection and set my manual addresses. I have ticked the 'connect automatically' button. Every time I reboot or wake up it reverts back to Auto eth0.I did have wicd installed but this was not reconnecting after wake up (said it was connected but I couldn't ping etc), this is a pain also.
When logging in, I suddenly got a message saying "It appears you do not have the hardware to run Unity", and it initialized the old GNOME 2 desktop.
Ofcourse I have the hardware to run Unity (an NVIDIA GTX 580), and it has worked normally until now...
Now Unity won't come back, even after logging out / in or rebooting. The video driver works normally and NVIDIA X Server Settings does not show that there's anything wrong with my video card or drivers.
Is this a bug? Did this happen to anyone else? How do I get the Unity desktop back?
I was recently having problems with Me TV, and I had to kill it in a terminal window. When I killed it, it didn't release the DVB-T stick and when I launched Kaffeine, it told me that there was no device available. I re-booted rather than trying to figure out where the lock file was or whatever the problem might have been. Now, when I boot into my desktop, I am missing the menu bar and the task bar. Also, under Applications -> Settings -> XFCE Settings Manager, the Panel icon doesn't launch any settings dialog when clicked. How can I get my menu bar and task bar back?
All my panels and desktop and wallpaper disappeared. I don't know how to get them back without restarting KDE4. I have too many things open. I can't right click the desktop > appearance settings and I don't know what to input into alt+F2 to get that system settings menu. Any ideas?
Running Slackware64 13.1 here. I started up Firefox this morning and all the text is completely blank - all the menus have disappeared and everything. I can't really think of a great way to explain it clearly so I've attached screen grabs of Firefox and Thunderbird (which has the same problem). Other GTK apps seem to be fine, it's just the Mozillas as far as I can tell.
I have tried removing both with code...
And then I reinstalled both Firefox and Thunderbird from .txz files I downloaded from a repository, but they're still the same. Firefox version is 3.6.3 and Thunderbird is 3.0.4.
Seems like i have an issue, and the applet vanished even though after some attemps typing to reintate it with: ALT F2. nm-applet I was advised to insert the gui panel but seems i do not have on version 10.04
I came into work this morning to find XFCE's window manager completely broken: no title bars, unable to move windows around, and unable to focus on a window to type in it (terminal, browser address bar, etc.). I tried going into the preferences then window manager settings, but just got a blank panel. Deleting .config/xfce4 didn't solve the problem.
I'm thinking of just doing a clean install of Xubuntu, or more likely another Xfce-based distro, since my current setup (regular Ubuntu with Xubuntu also installed) is quite messed up (same startup applications being used for Gnome and Xfce, and various other issues). I can't remember whether I did any updates last Friday that might have broken it.
Interestingly I used to have similar issues with Xmonad when I used it - some features didn't work properly and I had to restart the WM to fix them. Never did find a proper solution.
I've decided to give ubuntu another test drive now that I got a bigger and better desktop. I downloaded the latest version of ubuntu, loaded it into my usb stick and booted from it. I then clicked on the install icon on the desktop to start the installation. Everything was going ok, until I came to the partitioning part. I had already (on windows 7) created a separate partition for ubuntu which is 56GB. So I chose "manual partitioning" and selected the ubuntu partition as /home and began the installation.
Everything seemed to have went well, the window suddenly closed and then nothing happened. I waited for 15mins and still nothing happened. I decided to restart and see what happened, but I discovered that I couldn't boot into windows anymore. It said something about intel boot manager cannot find filesystem. So I decided to boot back from the usb and see if I can reinstall ubuntu, I came to the partitioning part and all the drives were gone, I couldn't see anything, it was blank.
My Sound and Network Applets have disappeared. Probably with help from a seven year old. When I right click the panel to "Add to Panel" neither Sound/Volume nor the Network Applet are available in the list. So how do I fix it?
