Design and Implementation of the compiz-based switcher plug-in for the csdn open-source summer camp

The special effect plug-ins provided by compiz are not enough or powerful enough. To better experience the special effects of compiz, we can install the special effect plug-in and enter the following command on the terminal: sudo apt-Get install compiz-plugins to download and install the special effect plug-in.

1. Install the compiz special effect plug-in

In this process, some problems may occur, such as the dependency problem. We need to update the source. For the update source, pay attention to the following points:

1. Set software updates

Note: select the primary server.

2. Update Source

Enter the command sudo apt-Get update on the terminal to update the source. Generally, this is acceptable. However, if the hash check does not match, the update will fail, at this time, we can try to enter the command sudo apt-Get upgrade on the terminal, so that the update can be successful. If there is still a problem, we can only try to replace the source, or change the network.
