Ubuntu – Change lock screen style on gnome classic desktop

NB: You SHOULD NOT do this on a production system unless you are willing to face potential breakage.

I would suggest simply removing the Ubuntu classic session's session file (I believe this is somewhere within /etc/X11).

You could then remove the gnome-panel package, but I wouldn't suggest removing anything else for now. Better safe than sorry.

11.10 Overview

The older GNOME 2.x experience has been retired in GNOME, however you can use the GNOME 3.x classic mode (as shown below) to make an approximation of the older experience.

install prerequisites

In the software center you have the option to install Gnome Shell :

Similarly - search for CompizConfig Settings Manager and install this package - we'll need that later.

Whilst you are there you can also install gnome-tweak-tool to further customise your desktop.

To quickly install all three of these at once, copy and paste the following into a terminal:

sudo apt-get install gnome-shell compizconfig-settings-manager gnome-tweak-tool

enabling compiz

Now perhaps the tricky part - getting gnome classic to function with compiz:

In a terminal copy and paste the following:

gksudo gedit /usr/share/gnome-session/sessions/gnome-classic.session

Now edit the file shown to contain this line entry:

How to login to Gnome-Classic

Save, logout and in your session options choose Gnome Classic

Changing the theme

You'll notice that the default Ubuntu Ambiance theme doesn't look great in Gnome Classic. We can correct this by changing to a Gnome 3 friendly theme.

... and choosing Appearance

Change the theme to Adwaita...

Note - see the linked questions below for other theming options.

Changing Icons

Launch gnome-tweak-tool via the menu option:

• Applications --> Other --> Advanced Settings

Change the icon theme as shown:

Restructure the desktop layout

Now lets get back the panels to something that we are familiar with...

Press Alt+Win and right-click the top menu bar - N.B. Win is the Windows Symbol key

(If you are using Gnome Classic (No Effects) i.e. gnome fallback mode then to add to the panel use Alt and right-click)

Choose Add to Panel

Click the option shown and click the button Forward

Repeat the Alt+Win + Right Click the date and choose Delete to delete the clock.

Repeat this delete procedure for the other applets on the top-panel.

Note - if an error appears indicating that the Panel has reloaded you can safely ignore this.

Repeat the Alt+Win + Right Click the top panel - add the applet Accessibility.

Repeat the Alt+Win + Right Click on bottom panel - add the applet Show Desktop and move to the bottom left.

Repeat the Alt+Win + Right Click on bottom panel - add the applet Wastebasket and move to the bottom right.

Now we need to change the number of workspaces back to two.

Navigate to Applications - Other - CompizConfig Settings Manager - General Options - Desktop Size and change the Vertical Virtual Size value to 1

Install the indicator-applet

Now lets install the indicator-applet:

• see the linked question below to add a PPA containing the indicator-applet

To add to the panel:

Alt+Win+Right click the panel and choose Add To Panel and add the following indicator

Finish off by Alt+Win+Right click the indicator-applet and move it to the right side of the top panel.

Optional:

• You can install fonts-cantarell if you want to use the default upstream GNOME font
