General Discussion / Re: LibreOffice in a Microsoft Office world
« on: December 08, 2013, 07:37:20 PM »
At my school, I install LibreOffice for Windows on the teacher computers.
That's the best approach to avoid MS Office's problems: don't use it.

But that said, most of our teachers and students are going crazy about Google Docs, so not many .odt files are sent around.

What kind of "problems" are the teachers having? How about students submitting PDFs instead?

General Discussion / Re: Spare units and printer assignment by host name
« on: November 19, 2013, 07:31:13 PM »

You could prepare a remote update script for printer configuration that looks at the MAC address of the network card, and configures printers based on that.


When you give out a loaner, you can go to the server and change this script, no need to change anything on the loaner itself. And the printers will get configured as soon as the laptop connects to the network.


What do you think?

Q&A / Re: How to install using a live CD
« on: October 14, 2013, 08:02:26 PM »
That's a solution for installing it, but if the goal is to test Ubermix on the hardware before installing it, I'm afraid there is no option for that.
As JPucheu said, to get an idea if you like Ubermix, use the virtual image.
To test hardware compatibility, I suggest using Ubuntu 12.04.3, which uses the same kernel as Ubermix 1.31 (or pretty close).

Oh, digging into your comment of aufs not in the mainline kernel, I found out about its status, and suggestions to go with overlayfs, which is part of mainline kernel.

What are your thoughts on this?

Eventually, Ubermix may work through btrfs snapshots anyway, I guess?

Mmm... so that would possibly open the door to taking the kernel from Saucy, for example, which is up to 3.11 as well.

I was just curious, because I've seen that the Broadcom brcmsmac driver is much improved in those.

General Support / Ubermix 1.31 and Ubuntu Mainline Kernel PPA
« on: October 08, 2013, 12:38:13 AM »
Hi,

I am starting to explore Ubermix 1.31. I am curious about making it possible to use standard Ubuntu kernels. How is this sorcery achieved? :D

In particular, I am going to try installing 3.11 from the Ubuntu Mainline Kernel PPA:
http://kernel.ubuntu.com/~kernel-ppa/mainline/

Let's see if it blows up!

I swear to you that this was "successfully" reproduced on two different computers with two different Broadcom cards, with the Ubermix 1.082 kernel, and with the bcmwl-kernel-source from your PPA :)

I will try with Ubermix 1.3, anyway. Fortunately for me, the devices with Broadcom here are within my reach, and I could re-image them relatively easily if this gets fixed.

Have you followed these steps to find out which network card you are using?

It's possible that it needs some additional driver, such as Broadcom:

I agree, it's a great app.
In our customized Ubermix, we add:
- Musescore
- LMMS
- TuxGuitar
- Ardour

Hardware Specific / Broadcom BCM4313 and FusionInventory
« on: September 03, 2013, 01:03:16 AM »
Hi,

At my school we deploy FusionInventory agents (with GLPI) for all our Windows machines. We have also been using it with our Ubermix machines, but I am running into a problem with Broadcomm BCM4313 wireless.

Due to 802.11n compatibility, I have installed bcmwl-kernel-source version 6.20, from jklein's PPA, and the driver wl works wonders compared to the open source version included in kernel 3.8.x.

But it makes it impossible to continue using FusionInventory. When the agent inspects the wireless card with this driver, the kernel crashes, with an error message about "tainted code" in the wireless module.

Has anyone had anything like this? I am worried that a couple of months down the line, I will start to have laptops crashing left and right, and loads of stress finding a fix :)

How-to / How to use the standard Unity (3D) environment
« on: September 03, 2013, 12:49:48 AM »
Hello everyone,

At our school, we have customized Ubermix 1.082 to use the standard Unity environment instead of the Ubermix Netbook Launcher. This was decided after running Ubermix last year and getting student feedback. With our current machines (Core i3, 4Gb of RAM), the general perception was that the Ubermix environment became cumbersome for running multiple applications at the same time. In hindsight, maybe we should have looked at the Xubuntu interface too, but too late now.

We are running into some strange issues related to the start of the Xsession:

- Using LightDM, sometimes the Unity panel doesn't get loaded. You can see the desktop, and shortcut keys like Ctrl-Alt-T or Super-S work, but you don't see the launcher. This happen on first boot after installing Ubermix. On second boot, it works, but the login takes a very long time. On third boot, it logins quickly, and stays like that on further boots.
However, if the user changes the password or turns off autologin, then the Unity panel NEVER loads. This has caused us a lot of pain, because a large group of students want to change the password "password" to prevent pranks by classmates.

- I found out that changing to GDM, the login process is slightly slower, but the Unity panel always loads. However, and just for fun, we now run into bug 934618, and if autologin is turned on, GDM crashes: https://bugs.launchpad.net/ubuntu/+source/gdm/+bug/934618

Right now, I have used remote updates to install GDM for everyone and force autologin off, so we are at a stable point, and I can breathe and write this post :)
It's obvious that LightDM is starting the Ubuntu session in a different way than GDM does. I would love to trace that and find out at which point the Unity panel service gets started compared to the rest of it, but I know very little about X sessions.
Also I expect this issue of autologin and disappearing panel doesn't happen in standard Ubuntu, so I wonder how the aufs mounting may be affecting this.
Any pointers to dig deeper would be most welcome.

I realize I am pushing far from the Ubermix supported stuff, but no harm in asking!
Cheers!

How-to / Re: Edit Favorites Menu
« on: September 03, 2013, 12:48:45 AM »
Have you tried something like this?

Code: [Select]
gsettings set com.canonical.Unity.Launcher favorites "['nautilus-home.desktop', 'google-chrome.desktop', 'firefox.desktop', 'libreoffice-writer.desktop', 'gimp.desktop', 'banshee.desktop', 'openshot.desktop']"
It works for me, but I'm using the standard Unity launcher.

Hi,

I am experiencing some minor issues with our Ubermix deployment. I think some of our students have created their own users on their laptops, and removed the user "user". And oops, there goes the .network-autostart file.

Can we move that file somewhere else? An easy place would be /home/.network-autostart
Maybe create a whole hidden folder inside /home/ in case there is other stuff to add later.
Or even /usr/local/lib/remote-updates/network-autostart?

I don't know the reasoning behind the current location for that file, though. Is there something I'm not seeing?

Development and Scripting / Re: Uptime Script in development
« on: May 09, 2013, 11:34:55 PM »
No, I found it quite easy.

I did it through remote updates:
- Add the package repository
- Add the signing key for the repository
- apt-get update, apt-get install fusioninventory-agent (see the instructions on their website)
- Then I overwrite the /etc/fusioninventory/agent.cfg file with my own.
- I also deleted the /etc/cron.daily/fusioninventory-agent file, and added a modified one to /etc/cron.d/ so it runs every 4h instead of once per day, but that's optional.

Not necessarily related to your uptime script, but as a good inventory option, I just deployed the Fusion Inventory agent from here:
http://www.fusioninventory.org/overview/
It reports to our existing GLPI server through a plugin on the server.

Here is GLPI:
http://www.glpi-project.org/

Through this I get a really nice database of all the laptops, including hardware and software inventory details.
Very recommended.
