Install Emerald Theme Manager on Ubuntu 11.10 Oneiric Ocelot

Emerald is beautiful window decorator which has a lot of fans back then. Unfortunately, Emerald is not included in Ubuntu Oneiric repositories so you can not easily. So, today I'd like to show you how to install Emerald on Ubuntu 11.10 Oneiric Ocelot both compiling via sources and installing via PPA. Before we jump, please take a look at a sample of Emerald Window Decorator theme (image via: WebUpd8)

Installing from source
Let's jump into our first method "Installing from sources". I found this method yesterday on Ubuntuforums.org, so please refers to the appropriate thread for further information.
Open the Terminal and type the following command to install applications and tools for compiling Emerald from sources:

• sudo apt-get install git autoconf libtool libwnck1.0-cil-dev libwnck-dev intltool libdecoration0-dev

Once installed, you must download the Emerald source and patche to work on Unity (Ubuntu 11.04 and Ubuntu 11.10), compile and then install it. Those steps can be done by typing the following commands:

• wget http://cgit.compiz.org/fusion/decorators/emerald/snapshot/emerald-0.9.4.tar.gz
• tar -xf emerald-0.9.4.tar.gz
• cd emerald-0.9.4
• cd src
• rm main.c
• wget http://www.learn-digital.com/ubuntu/emerald-0.9.4/src/main.c
• cd ..
• ./autogen.sh && make clean && make distclean && ./configure --prefix=/usr && make && gksu make install

Installing via PPA
Thanks to Andrew @WebUpd8 who provides PPA for Emerald so we can install it easily on Ubuntu 11.10 Oneiric Ocelot. Type the following command to install Emerald via PPA:

• sudo add-apt-repository ppa:nilarimogard/webupd8
• sudo apt-get update
• sudo apt-get install emerald

Once Emerald installed on your system, please select a theme from Emerald Theme Manager and activate by typing:

• emerald --replace

To have Emerald run at startup you must configure it via CompizConfig Settings Manager a.k.a CCSM. Have not installed CCSM yet? Type this command:

• sudo apt-get install compizconfig-settings-manager

Then open CompizConfig Settings Manager (CCSM), on the left pane select "Window Decoration" plugin and under "Command", enter: "emerald --replace".

Regards.

Fix VirtualBox Error "Failed to access the USB subsystem" on Ubuntu 11.10 Oneiric Ocelot

When you run VirtualBox at the first time on Ubuntu 11.10 Oneiric Ocelot, you may get this following error message: "Failed to access the USB subsystem. VirtualBox is not currently allowed to access USB devices. You can change this by adding your user to the 'vboxusers' group. Please see the user manual for more detailed explanation."

As describe in the error message, we must add the user to 'vboxusers' group to fix this problem. Unfortunately, there is no GUI tool to manage users and groups on Ubuntu 11.10 Oneiric Ocelot (yet). So, we must do it manually by using command line.

Assume that we have user "hok00age" and we'll add him to member of "vboxusers" group. Simply type the following command:

• sudo usermod -a -G vboxusers hok00age

Make sure you have done it correctly by checking "/etc/group" file:

• cat /etc/group

Restart your computer and once computer restarted, run VirtualBox and check if the problem is fixed.

Enjoy :)

Ubuntu 11.10 Wallpapers and Theme

Actually, Ubuntu 11.10 just leave 4 themes (GTK) to choose, that is Ambiance, Radiance, High Contras, and High Contras Inverse. We can't  change anymore the appearances of window by manual (window color, window border, etc) and we also lost toolbar menu in the Nautilus.


Notable Missing Application 
After finish installing Ubuntu 11.10 to our system, we hope that we will find a new experience without losing some great feature that available in previous version. Well, some application has much improvement, but some application has lost. here some lost application/features that we missed the presence.

• We miss the toolbar menu in Nautilus. although this looks better but this  progress has limit our capabilities.
• Synaptics, Ubuntu Software Center 5 can replace all functionality of synaptics, but for some reason 'on the same' computer Ubuntu Software Center runs so slowly compared with synapics.
• I can't take fast Screenshot using compiz, compiz have utility to make fast screenshot by pressing the <super> + <button 1> , now i can't do it and back to the classic way :(
• We have lost theme 'appearence' utility which let's us setting such window color, icon, default font, and window border. we're only left 4 theme to choose.
• Gnome Classic, we also lost theUbuntu Classic as alternative desktop environment in login page, as we can see on login screen we have only a choice to Unity and Unity 2D. 

Downloads The Ubuntu 11.10
You do not need a long time to get some fresh installation of Ubuntu 11.10, just approximately 10 minute. Interesting to try it dude ? you can download and burn the ISO to CDs or Flash Drive then install it to the computer, download the ISO through following links :

Ubuntu 11.10 Oneiric Ocelot does not have appearance properties so, we can't change GTK  theme's option and icon theme easily. Fortunately, there is such an application called dconf-tools that can be used to change some gnome appearance properties including gnome icon theme.

Install dconf-tools by typing the following command:

• sudo apt-get install dconf-tools

Once installed, run dconf-tools and then go to org-->gnome-->desktop-->interface-->enter the name of your desired icon theme at "icon-theme.

If you don't know the exact name of your icon theme, just go to /usr/share/icons
