How to Install the Gnome Classic Desktop in Ubuntu 14.04

In Ubuntu 14.04, you cannot change the window control buttons to the right side of the title bar anymore. If you prefer the window control buttons on the right, or you just don’t like Unity, you can easily go back to the classic Gnome desktop.
NOTE: When we say to type something in this article and there are quotes around the text, DO NOT type the quotes, unless we specify otherwise.

To install the Gnome desktop, press Ctrl + Alt + T to open a Terminal window. Type the following line at the prompt and press Enter. The line is actually two commands. The first command (before the semicolon) updates Ubuntu and the second installs the Gnome desktop.

sudo apt-get update; sudo apt-get install gnome-session-fallback

Type your password when prompted and press Enter.

The progress of the installation displays and then a message displays saying how much disk space will be used. When asked if you want to continue, type a “y” and press Enter.

When the installation is finished, close the Terminal window by typing “exit” at the prompt and pressing Enter.

Click on the system menu in the upper-right corner of the screen and select Log Out to log out of your session.

On the login screen, click the Ubuntu icon.

A list of available desktop environments display. Select the GNOME Flashback option for either Compiz or Metacity.

You are automatically returned to the login screen. Enter your password and press Enter to log in.

The classic Gnome desktop displays with the standard Gnome menus in the upper-left corner of the screen.

 To compile and install the proprietary Realtek 8192cu driver, run the following commands in an open terminal:

sudo apt-get update && sudo apt-get install git build-essential linux-headers-generic dkms
git clone https://github.com/dz0ny/rt8192cu.git --depth 1
cd rt8192cu
sudo make dkms

restart the computer


1. Development Environment
System version: Ubuntu 14.04.1
Kernel version: 3.16.0-30-generic
Gcc version:4.8.2

2. Compile the Driver
2.1. Compilation tool and kernel sources
Before you compile the driver, please make sure you have the correct compile tool and
kernel sources.
We can install compile tool gcc by command “apt-get install gcc”
Note : We recommend you use a suitable compile tool to compile our driver.
For example:

According to the command “sudo cat /proc/version”, we could see your linux system is compiled

by gcc4.8.2. So we recommend you use gcc4.8.2 to compile our driver if possible.
2.2. Compile and install the Driver

1. Access the directory of driver.

2. Before compile, make sure the parameters in “makefile.c” is suitable for your
compile environment of your Linux system.


ifeq ($(CONFIG_PLATFORM_I386_PC), y)
EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN
SUBARCH := $(shell uname -m | sed -e s/i.86/i386/)
ARCH ?= $(SUBARCH)
CROSS_COMPILE ?=
KVER := $(shell uname -r)
KSRC := /lib/modules/$(KVER)/build
MODDESTDIR := /lib/modules/$(KVER)/kernel/drivers/net/wireless/
INSTALL_PREFIX :=
endif



Explanation:
· KSRC is used to specify the kernel source path for driver compilation.
· CROSS_COMPILE is used to specify the toolchain.
· ARCH is used to specify the target platform's CPU architectures such as arm, mips,
i386 and so on.
1If your Linux kernel does not support 802.11, please annotate macro

“CONFIG_IOCTL_CFG80211” in “makefile.c”.
CONFIG_IOCTL_CFG80211=n
ifeq ($(strip &(CONFIG_IOCTL_CFG80211)),y)
EXTRA_CFLAGS + = -DCONFIG_IOCTL_CFG80211 = 1
EXTRA_CFLAGS + = -DRTW_USE_CFG80211_STA_EVENT = 1
endif

3. Type “sudo make” to compile the driver file.

4. Type “sudo make install” to install the driver file.
