Netwrok Manager in XFCE4


Hello Everyone,

Since updating to KDE 4.8, my laptop has gotten very slow. Applications open slowly and just seem to drag. I suppose it may be a little much for this 5 year old laptop. I decided I would use XFCE for a while, but I can't figure out how to get Network Manager to work with it. Network Manager only seems to work when I run KDE. I used to like running updates in level three, and inet1 used to connect to my wireless in level three, but Network Manager won't. Also, there is no task bar in XFCE to add widgets to (like Network Manager.) Anyone know how to fix this?

Thanks

Bob

Create new app launcher in XFCE panel and use following command
Code:
kcmshell4 [kdeinit] --icon networkmanager kcm_networkmanagement kcm_networkmanagement_tray
. It will launch KDE system settings module which can control NM.

Thank you, that does indeed bring up a dialog box called "Configure the Network Management Tool", but doesn't actually bring up any thing to connect. /etc/rc.d/rc.networkmanager does tell me network manager is already running, but it is not connecting to my network. I need the controls that I have in KDE. Can I get an icon in the tray like that?

Bob

EDIT: I mis entered your command. It does work. Thank you for your help.

There is applet called smth like network-manager-applet (prebuild packages for SW also available) which when started minimize itself in system tray and you can control network connections, also scan on the fly for wireless networks. But I guess it's going to be added when xfce-4.8 or 4.10 enters slackware-current. But it has dependencies for gnome-keyring, and maybe gnome-keyring has more additional dependencies. And I'm not sure it can work along with slackware-current, smd else should confirm it.
But I'm also using this kind of setup (quick launch icon for KDE network settings module) and I add manually my wireless network and it connects without no problem. If you want to connect to wireless network you should choose Wireless -> Add - wireless network and a new window will appear when you can enter wireless ssid and other settings, and next to the input box for ssid there is button 'Scan' which will give you option select from wireless networks available.

Let's try to fix the KDE-4.8 performances first...

There are two well known workarounds, about the sluggish KWIN's 3D effects:

- Disable the blur effect.
- Scale method set to Accurate.

And if still you are not satisfied and you want The Final Solution, disable that Desktop Effects entirelly.

I prefer to use WiCD for managing connections...I use it with XFCE in VectorLinux (Slackware-based) and with KDE in Slackware 13.37. It is now the first thing I install after loading a fresh distro. NetworkManager < WiCD for me ;-)

What version of Xfce are you running? There should be a panel and the icon for the NM applet will show up, once installed, on the right side of the panel.
XFCE 4.8 defaults to two panels, one at the top and a smaller one bottom center. I always delete the smaller one and move the top panel to the bottom of the screen.

Everything you need to run NetworkManager in Xfce can be found here, http://connie.slackware.com/~rworkman/xfce-4.8/
in the extra directory. but you will need a few of the dependencies which are found under "packages," then "i486" or "x86_64," and, finally, "deps." You will need GConf, ORBit2, gnome-keyring and libgnome-keyring.

Once installed, go to Settings, Sessions & Startup, Application Autostart, and check the appropriate box and then log out and restart Xfce.

Xfce runs most KDE applications very well, but every time you open a KDE app several instances of "kdeinit4" will be loaded into memory and they will not unload when you are done with the application(s). This can chew up a couple of hundreds megs of memory. I just started Dolphin so I could have an example and 3 instances of kdeinit4 where started. So there is 42 megs for Dolphin and another 37 megs for the kdeinit4-s. When you close Dolphin you get back the 42 megs, but the kdeinit4-s remain in memory. I just fired up Gwenview and two more kdeinit4-s appeared using another 29 megs. Again, these things won't go away until you manually terminate them. Just FYI.

Enjoy Xfce. The new version, 4.10, is looking good.

+1 for wicd. DE agnostic, lightweight and robust.

I love wicd, I love networkmanager. There's a choice between two good GUI configurators now. And if you use wicd in KDE, don't forget that there is now a wicd configuration tool which blends in nicely with KDE (wicd-kde package in -current) with a Qt4 GUI interface instead of the GTK interface of the default wicd-client.
The particularly nice thing about wicd is that it has a console version of the client (wicd-curses) which can do anything the GUI can do.

I will have strongly disagree about wicd.

On at least three different occasions I've ran wcid and it only does the job for a short period of time before flaking out. We have had three different versions, two most recently, one upgrading the other, and not one is any better than the other.

The most recent experience was two weeks ago when I did a completely fresh install of Slackware64 13.37. Wicd will work for a few hours or even maybe a day, but eventually it will pop up and report there are no available networks. Maybe it has something to do with the way the wind is blowing at any given moment, but I'm sitting in line of sight of the router which isn't more than 12 feet away. Plus, at any given time there are anywhere from 15 to 20, sometimes more, networks running in this immediate area.

NetworkManager 0.9.2 has been rock solid, but unfortunately, NetworkManager 0.9.4, is not much better than wcid. Not knowing that I delete the 0.9.2 applet. Once I discovered 0.9.4 is as undependable as wicd, I hunted around and finally built a 0.9.2 applet so NetworkManager 0.9.2 can be used with Xfce.

BTW, is there a way to "refresh" wicd or networkmanager without having to reboot the computer? I've tried ifconfig, but it doesn't seem to help (I don't mean the "refresh" button in the wicd panel).

I have never seen issues like you describe.
Since you experience similar difficulties with wicd as well as networkmanager there could be an underlying issue with the wireless driver - or even with the hardware.

That could be, but there has never been a problem with NetworkManager 0.9.2 or the version before (0.9.0 ? ), only version 0.9.4, and wicd.

Edit in: BTW, this experience has been over the last 18 months with two different boxes in two different locations.

I have never used desktop effects. Don't like them. I have just a standard desktop. Apps still open sluggishly, and drag when running. XFCE4 is very snappy, like the old KDE used to be.

I am considering just going back to using inet1 for my wireless. It worked in runlevel 3 (where I like to do updates) and network manager does not.
