Q&A / Setting default launcher theme and orientation - system-wide for all users.

« on: April 24, 2013, 04:54:42 PM »

Having some issues with the launcher - I'm sure this is a rookie mistake and I think I've dealt with it before but for the life of me cannot remember what the solution was.

Menu bar shows on the side, not the top, and when I scroll past the last visible item, the whole thing disappears and all I have left is top menu.  No more launcher items.

Q&A / SBAC Secure Browser - system-wide?

« on: April 24, 2013, 04:45:10 PM »

For single user this is easy, but for our shared-use ubermix systems, any ideas as to how we'd set up SBAC system-wide?

General Support / Installing on a system with no wireless

We attempted to install on a system with only a 10/100 card in it, and the system just hangs.  Any thoughts?

Q&A / provisioning per-user autostart scripts?

« on: January 10, 2013, 11:56:59 AM »

This should be simple, but for some reason it doesn't appear to run.

The goal here in our shared netbook environment is to
a) disable the password requirement on the screen saver
b) cleanup any leftover files (lock and .parentlock) in the user's browser profile

The script works when run from a terminal, but does not run at login despite a .config/autostart entry to launch it...

The autostart file (.cleanup.desktop) contains:


[Desktop Entry]
Type=Application
Exec=bash ~/.cleanup.sh
Hidden=false
NoDisplay=true
X-GNOME-Autostart-enabled=true
Name[en_US]=cleanup
Name=cleanup
Comment[en_US]=cleanup
Comment=cleanup
~                 

And the .cleanup.sh script contains:

#!/bin/bash
sleep 10
echo -en "\07"
killall -KILL firefox-bin
killall -KILL firefox

find ~./.mozilla/ -iname ".parentlock" -exec rm -f {} \;
find ~./.mozilla/ -iname "lock" -exec rm -f {} \;
find ~./.mozilla/ -iname "places.sqlite" -exec rm -f {} \;
find ~./.mozilla/ -iname "places.sqlite-journal" -exec rm -f {} \;
touch ~/I_RAN

General Discussion / Cloning USB Keys - DD no work-ey, Clonezilla does?

« on: January 03, 2013, 03:58:27 PM »

Ok, So I must be doing something wrong.

I put in my modified key.  dd if=/dev/sdb of=my_key.img.  done

I now put a fresh key in, reverse the process (flip dd if and of arguments).  Takes forever.  ANd then will not boot.

On a hunch I boot the netbook into clonezilla and make a backup of the key that way.  Much faster (odd, that).  Put in a fresh key, and reverse the process.  WAAAY faster than dd.  And it works.

I suspect I have tripped over one of the many gaps in my knowledge - can anyone enlighten me as to where I went wrong? 

BTW, once I got the key backed up with clonezilla, I stuck as many keys as I could into the netbook, and did the one to multiple restore.  quick.  Nice trick for making a bunch of keys, though I somehow suspoect this too is common knowledge. :/

General Discussion / Disable nm-applet by group?

« on: November 27, 2012, 03:22:38 PM »

I was messing with polkit to disable nm-applet so kids don't kill networking for the next student to use the device or themselves...  We're using a shared device model so this is kind of important.  Any ideas what I might be missing to achieve this?  The info I found had me do the following...

File: /etc/polkit-1/localauthority/50-local.d/org.freedesktop.NetworkManager.pkla

[nm-applet]
Identity=unix-group:adm
Action=org.freedesktop.NetworkManager.*
ResultAny=yes
ResultInactive=no
ResultActive=yes

but users not in the adm group still get the applet, and are still able to disable networking...

Ideas?  Am I barking up the wrong tree?

Q&A / Making changes permanent/restorable...

« on: November 26, 2012, 02:48:17 PM »

I'm probably being dense, but once I get customization done, what is the best way to make it "restore-able"?
ie copy /etc from -aufs to -generic?  Or am I going about this all wrong?

Q&A / Shared netbooks, login successful, blank screen, launcher does lot load

« on: November 01, 2012, 01:53:01 PM »

Any ideas?  I almost wonder if this is a permissions/group membership issue.  I can still login with the default "user" account.
