OpenSUSE Install :: Cannot Open ConsoleKit Session: Unable To Open Session

Apr 11, 2010

The following message comes up when I boot up: Logging in user Warning: Cannot open ConsoleKit session: Unable to open session: Launch helper exited with unknown return code 0. When I press OK, the system completes the start up and everything looks normal. But when I try to connect to internet, I get the following message:

KNetworkManager cannot start because the installation is misconfigured. System DBUS policy does not allow it to provide user settings; contact your system administrator or distribution. KNetworkManager will not start automatically in future. If I reboot the system, I logg in successfully. So far the problem has appeared approximately upon every second time I boot up. Rebooting the system seems to take care of it.

Don't know what info is of interest. I'm using

Opensuse 11.2
KDE 4.4.2 (Factory)
After upgrade from 4.4.1 to 4.4.2 it worked fine for a week or so.

Ubuntu :: Edubuntu Have Any Material For Toddlers?

Jul 26, 2010

I've never messed with it at all. My brother and his wife have a 2 year old and they wanted to get a computer both for their use and for some educational programs for their kid. They don't really have a budget at all but I happen to have an old computer sitting around that I'm going to give to them.

I've heard about the Edubuntu project, but all the stuff I can find says it's intended for ages 6 and up, which is a bit too advanced for a toddler. Does it have anything really basic that might be worthwhile for a 2 year old?

Ubuntu :: Can Different Desktops - Edubuntu - Run On One Kernel

Jun 6, 2011

On an old Acer Aspire 3610 notebook to be used by parent and children

I have installed a dual boot configuration with:-

What is the best way of adding Edubuntu desktop for children's use?

In one kernel can one user (parent) have Ubuntu 10.10 desktop and other users (children) have Edubuntu 10.10 desktop with parental controls?

i.e. can different desktops be configured to run for different users on one kernel?

Or is a triple boot installation necessary:

Vista, Ubuntu, Edubuntu?

I guess that I could reformat and use the partition /dev/sda4 for Edubuntu if necessary.

Ubuntu Installation :: Mouse At Login Edubuntu 10.04?

Oct 27, 2010

I have an IBM Thinkpad T30 that I have been triple booting, kubuntu, ubuntu and xubuntu, on sda1, sda2 and sda3, respectively. (The swap partition is sda6, sda5 is /home for kubuntu.) Everything was working fine until I decided I really wanted edubuntu on sda2 instead of ubuntu. I installed a clean edubuntu 10.04 onto sda2. At the log in screen, the mouse is completely dead. The mouse still works in kubuntu and xubuntu when I boot to one of those. The mouse worked when sda2 was ubuntu not edubuntu. Exactly the same hardware -- one laptop. So the problem is definitely edubuntu.[URL]..

Ubuntu :: Need Edubuntu Disc Every Time Update?

Nov 23, 2010

Every time I update anything, I'm asked to insert my Edubuntu disc. I booted from the CD once and ran it in LiveCD mode. I'm pretty sure I've never installed anything from it. So why do I need to put it in all the time? I'm not even running Edubuntu. I looked at the software sources, and the only CD listed is the Ubuntu one, and it's unchecked anyway, so how do I make it stop wanting the Edubuntu CD?

Ubuntu Networking :: Setup A Network Of 21 Computers Running Edubuntu 10.10?

Feb 7, 2011

I have recently set up a network of 21 computers running Edubuntu 10.10 I use iTalc to communicate with the pcs and also to shutdown all of them at once. The only problem I have, is it doesn't start up again with iTalc. So I switched to ClusterSSH. Only problem I have now is that everytime I run cssh, I need to manually add IP addresses of all the pc's, before I can start issuing commands. Is there a config file or something I can populate with all the IP addresses so that it starts up with all of them already added? And while we are at it, the command to start up a computer on the network?

Ubuntu Installation :: Installing Edubuntu: Broken DVD-Drive - No USB-Boot

Apr 25, 2011

I would like to install Edubuntu 10.10 on this ancient Toshiba with Windows XP on it. The situation is a little complicated since I have no stable internet connection (I can not download Edubuntu once more). Now I realised that the DVD-Drive is broken and I can not boot from DVD to install Edubuntu. I have, however, an external USB-Drive, but there is no Boot-Option from USB (Phoenix Bios V. 1.3). So now I figured different options:

I could update my PhoenixBios to have a USB-Boot-Support. But I don't know if that's possible, so I am asking for opinions.I sucessfully installed Ubuntu 10.10 with Wubi on the Laptop, but I wasn't able to install the packages for Edubuntu. Any time I put the DVD in my external USB-Drive and tried to mount with Synaptic I got the error message: "E: Could not mount CD-Rom". So I could install Ubuntu 10.10 with the CD, the Edubuntu-packages in addition with the DVD afterwards. Is there no way to install Edubuntu directly with Wubi?

Ubuntu Installation :: Edubuntu 10.10 LiveCD - Checking Battery State - Can Not Mount

Apr 14, 2011

I am having a hard time installing Edubuntu 10.10 on a Toshiba L30

System specifications:
Toshiba L30-140
Intel Celeron M CPU 410 1,46 GHz
ATI Radeon XPress 200M Series
Bootable with CD/DVD only

While installing Edubuntu, I encounter two problems:

Can not mount...

I will reach to the screen to select to install Edubuntu and it will even show the green leds. I push F1 to get more detailed messages. After 2 minutes or so I will have this error message:


This error appears randomly. Out of ten attempts to boot, 6 times I will get this error message. 4 times I will get to...

Checking battery state ... [OK]

This will advance up to "Checking battery state... [OK]" which will freeze there with no DVD or HDD-Activity visible.

I encountered very many threads on the "checking battery state" issue, but they seemed obsolete to me, since most of them referred to Ibex. Also this is the Edubuntu LiveCD, it has not yet been installed on the HDD.

Nonetheless, for the Checking Battery State problem I have tried solutions for Ibex such as "acpi=force pci=noacpi" and "acpi=off". But it wouldn't work. Some people also suggested changing the graphic configurations, this is ATI however, not Nvidia and the BIOS does not offer the option to change it.

Strangely, the installation has worked brilliantly (with the same dvd) on another computer (some Laptop Toshiba L30), so I don't believe it might be a damaged disk.

Programming :: Hashing The Components Of An Tcp Session To Assign/locate The Session In A Hash Table Bucket?

Nov 10, 2010

I have a very bad attempt at hashing the components of an tcp session to assign/locate the session in a hash table bucket. I am pretty sure that it has a very high collision rate and when there are a very large number of tcp sessions my application is having to search a long linked list to find the session within the bucket.

All the hashing functions I have found take a single string input where I need to input several integers and hash them into a single result. My guess is that any real hashing function is going to produce better results than what I am currently doing.

Ubuntu :: Can't Install Gnome3-session?

May 14, 2011

I installed gnome-shell from the respective PPA on my 11.04 ubuntu installation and I have problems running this combination smoothly! Sometimes when I log in I get Metacity windows and no Gnome session, sometimes I get the correct Gnome3 session...I guess that somehow the packages I have installed on my system got mixed up.Anyway: when I try to "sudo apt-get install gnome3-session" I get the following error:Quote:

The following packages have unmet dependencies:
gnome3-session : Depends: gnome-session-bin (< 2.33) but 3.0.1-0ubuntu1~build2 is to be installed

CentOS 5 :: Writing 2nd Session Of Multi-session DVD?

Jan 22, 2010

I am putting together some new systems for my customer and I'm having some trouble with a script that we use to back up files to a DVD R. The problem is that I can't write a 2nd session to the DVD unless I eject the disk and reload it. The drives are slimline type drives, Sony BD-5730S and Teac DV-W28S-V93, so they won't reload without human intervention. Opsys is CentOS 5.4 or RHEL 5.4. I've tried both AMD and Intel based mother boards. If i try this on Fedora 11 or 12 it works fine. This works on IDE attached drives but not a SATA attached drives. Fedora appears to use something called genisoimage instead of mkisofs. I can't get genisoimage to run on CentOS or RHEL.

Here's the code to setup the test files:

rm -f /tmp/BDtest/*
mkdir /tmp/BDtest
dd if=/dev/zero of=/tmp/BDtest/blank.iso bs=10M count=1
for NUM in {1..160}

Ubuntu :: Install Firefox Add-on To Guest Session At Login?

Jun 7, 2010

Adding Firefox add-ons to Guest Session?I wanted to include Add-on to Ubuntu Guest Session Firefox.Is there a proper or better way to do this? Procedure I used was as follows

1. Login to Ubuntu to a user account with sudo privileges (later sudoer account).

1. Switch to Guest Session

2. Install relevant Add-ons

3. Check what the home folder of the Guest Session is. It should be something like /tmp/guest-home.xxxxxx where xxxxxx = six random characters.

4. Switch to sudoer account

5. Open terminal and type


gksudo nautilus


I tested this with Flashblock and it seemed to work. I also admit that since I did the thing for the first time it was not that straight forward for me, but above procedure should work. With quick Googling I was unable to find straight forward method. There is a way to install Add-ons to all users from command line using -install-global-extension but this was not what I wanted to do. I wanted the Add-on just for the temporary guest account.

Ubuntu Servers :: Restrict User Session Numbers And Allow Resuming Previous User Session?

Jun 30, 2010

I am currently in a project to set up an LTSP server with 10 thin clients. I am using Ubuntu 9.10 (Karmic).

Installing server and booting clients are working fine. Now, according to the need, I have to restrict user session numbers and allow resuming previous user session.

I have achieved to do the first one, but still could not able to setup the second one. As per requirement, if some thin can have power failure, the same session should be restored back. I am confused here, if I need to focus on saving xsessions or saving gnome sessions. I am looking for a concrete solution as I am running out of time.

OpenSUSE Install :: Can't See 'Xfce Session' After Update / Fix It?

Dec 28, 2010

I'm a new openSUSE user. Thought of giving some other distros a try, so I started with openSUSE.

I installed the Xfce packages and when I went to go install a panel plugin, it said that it needed to install some other stuff, including an update of xfce4-session to xfdesktop. After I did this, I could no longer see 'Xfce session' in the "Sessions" part of the log-in menu when I tried to log-in again.

What do I need to do to fix this issue?

OpenSUSE Network :: Install And Configure My Vnc Session ?

Mar 4, 2011

I need some help install and configure my vnc session at my Opensuse.

Right now I have installed nx client which works fine and is listening on port 5901.

I also want vnc to use when I want to check exactly what is going on my work's computer (when I go home)

I am reading the tutorial here:

And I would like to ask you the following



For VNC client connection remember to open ports 5901-> in the firewall. (1 port/Xsession.) nxserver is listening to 5901. How to configure vnc to listen to 5902.

2. The guide also refers that


Here we "Prestart" vnc sessions for specific users, therefore no login screen is presented. This uses more resources as the VNC Session is running even when no client is connected to the session watching it. But there in lies it's advantage, "watching a session" and "using a session" are not the same thing! This method is very usefull for starting long running programs before going home. Once home you can re-connect to the session and see how things are going.

OpenSUSE Install :: Preventing Autologin That Happens When KDE Can Resume Session

I usually shut down openSUSE in KDE by clicking the shutdown icon and selecting "Turn Off Computer". When I boot back into openSUSE, my session resumes automatically without it asking for my password.While I don't mind KDE resuming my session because it saves time, me not having to reenter my password is a security risk. How do I turn off the autologin?

OpenSUSE Install :: Kill The Entire Session (as Root) For A User?

May 5, 2010

I've got a somewhat anemic box, resource-wise, set up in the office where any authorized user plus a guest account can log on. Guest is tightly restricted, but we get a lot of people passing through who need one-time or occasional access - this isn't the big problem. What's causing me problems is that a user will log in, walk away or go to the john and the screen locks. Next user (or this one comes back) and winds up doing another login. At the end of a week or so, I may have a couple of dozen sessions listed when I ask for "users". Since some of these session contain open applications they eat up an awful lot of a marginal amount of available memory. How do I kill the entire session (as root) for a user? Gotta be simple but it's not obvious to me.
