Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I was wondering if it is possible to change the default size of the launcher during guest sessions? It is rather large, and a little bulky (opinion), and I was wondering if I could change it so every guest session would have a smaller (example 32px or whatever) launcher size? (Ubuntu 12.04 and newer)

Thank you for your time and ansers.

You can try with the guest-session-prefs-lightdm kit.

README File:

guest-session-prefs-lightdm is a convenience kit that makes it easier for a system admin to configure the guest session feature provided by the lightdm package. The preferences are set via shell commands in these two files:

/etc/guest-session/prefs.sh
/etc/guest-session/auto.sh

The kit is shipped with the settings I made on my own computer. Some may share my preferences, but most admins who install guest-session-prefs-lightdm will probably make changes and/or additions to those settings.

My aim is to give the admins options, and the framework the kit offers for configuring guest sessions may be of greater interest than the particular settings that I happen to like. Still, my code snippets can serve as models.

I would suggest that you install guest-session-prefs-lightdm as is, and take it from there when you have reviewed the resulting changes in behavior.

Ubuntu 12.04

1) Go to this page to download the guest-session-prefs-lightdm-0.12.tar.gz package to your ~/Downloads folder.

2) Open a Terminal window and type:

  • cd ~/Downloads/
  • tar -xf guest-session-prefs-lightdm-0.12.tar.gz
  • cd guest-session-prefs-lightdm-0.12/
  • sudo ./install.sh

Note: The script install.sh will tell you if you need to install any package to complete the installation. eg (gettext)

3) Edit the /etc/guest-session/auto.sh file to add the command to resize the Launcher icons.

  • sudo nano /etc/guest-session/auto.sh

Add the following lines to the file:

# Change Launcher icon size to 32
gconftool-2 --type int --set /apps/compiz-1/plugins/unityshell/screen0/options/icon_size 32

enter image description here

Save the changes with Ctrol+O then Enter and Ctrl+X.

*4)*Finally you can lOgout and login in the guest account to see the changes.

Result:

enter image description here

Ubuntu 12.10 & 13.04

Thes steps are the same as 12.04, the only change would be the command to resize the icons.

Use:

# Change Launcher icon size to 32
gsettings set org.compiz.unityshell:/org/compiz/profiles/unity/plugins/unityshell/  icon-size 32

instead the gconftool-2 command.

NOTE: This kit by default has examples like display an info dialog, or create a link to a folder. You can change it according to your needs.

Hope this helps.
