Ubuntu does not have access to the Unity graphical interface solution

Ubuntu version: 12.04LTS graphical interface: unity2d

There are two weeks to solve this problem, and it is also a way to write a log record.

Bloggers are completely Linux novices, occasionally programmed with Ubuntu, and have little experience in tossing systems. When the boot is found into the Ubuntu graphics desktop, only a wallpaper, no icon or taskbar, reboot to normal. continued to boot all the time, bloggers can not bear, Baidu, "Ubuntu Desktop is not normal" and so on, got to let me toss a few days after the "Resolution" directive:

$sudo apt-get remove gdm$sudoinstall ubuntu-desktop$sudo Install Gnome-core

sudo reboot, directly connected to the desktop can not enter, an instant crash, because it is a dual system, the feeling of re-installed Ubuntu more trouble, and before the configuration of a lot of programming environment, can only try to save. With Ctrl+alt+f1/f2 and other discoveries can enter the command line, the command line operation is still normal, so I know just graphical interface problems.

Due to the various forums mentioned in Ubuntu using the Gnome graphical interface, so Bo Master 3 days to see the use of GNOME, tried a variety of re-install GNOME and GDM instructions, multiple restarts without fruit. Until the original graphical interface was found to be called Unity (Halo, Bo Master Toss System 0 experience AH) So uninstall the installation is not successful GNOME, re-turn unity on the line. Most of the posts are spit groove unity is not good, uninstall Unity Mount Gnome method: http://blog.csdn.net/chinawangyajun/article/details/7202550 So I am smart, Switch the objects of the relevant instructions to the object and assume that you can uninstall gnome to install unity. (Because the Linux plug-in dependency is more, so the simple interchange object does not work) results boot has been stuck in the Ubuntu logo, after switching command line, with the instruction StartX manual start graphical interface, get warning as follows:

So I decided to track down, search for solutions to these problems, and finally find the same situation and solutions in the Tianya forum, http://bbs.tianya.cn/post-itinfo-229777-1.shtml An Ubuntu English website (similar to stackoverflow) gives "how can I remove and re-install Unity?" The answer:

Refining it is:

Use this to Remove/uninstall Compiz Unity:

sudo apt-get remove compizconfig-settings-managersudo apt-get remove compiz-fusion-plugins-extrasudo apt-get remove compiz-plugins-extrasudo Apt-get Purge compiz*

Then-to-re-install Compiz Unity use:

sudoApt-getInstallunity-2dsudoApt-getInstallubuntu-DesktopsudoApt-getInstallubuntu-desktop-2dsudoApt-getInstallcompizconfig-settings-ManagersudoApt-getInstallxserver-XGLsudoApt-getInstallEmeraldsudoApt-getInstallcompiz-fusion-plugins-ExtrasudoApt-getInstallGit compiz-plugins-ExtrasudoApt-getInstallcompiz-plugins-ExtrasudoApt-getInstallUnity

This makes it easy to reinstall the UNITY2D desktop, and then install the Desktop Boot Manager dsktop manager such as GDM/LIGHTDM, in order to avoid the power-on manual start graphical interface cumbersome, in the future can also easily switch a variety of desktop gnome or KDE. But later found that installing GDM was not effective, so

sudo dpkg-reconfigure GDM

Move the cursor to select LIGHTDM as the default desktop manager. Finally, reboot see the familiar Ubuntu user login interface again.

All is done.
