Ubuntu8.10 Video Card Driver Installation and 3D desktop Activation

(1) hardware configuration problems:
Although some friends can use machines with lower configurations to run 3D desktops in Linux,

However, if there is a higher configuration, it will obviously run smoothly.
If you are planning to purchase a new video card, we recommend that you select a lower level than the "latest highest configuration;
This method is applicable to mainstream nvidia and ATI graphics cards, but not for Intel graphics cards and some old graphics cards,
I am amd64 dual-core 3800 + and nforce 7600gt in 1 GB memory, most of the 3D effects are enabled, very smooth.
Install the latest and most complete Ubuntu version whenever possible,
In this tutorial, 3D desktop is successfully enabled in Ubuntu 8.04, 8.04.1, 8.10, and amd64.
After the Ubuntu system is installed, you can usually start the graphical interface to log on, but this does not mean that the graphics driver has been installed.

(2) the simplest method for installing the latest official driver for ATI or NVIDIA graphics cards:
Let envyng, the dummies software, help you!
The advantage of using envyng to install a driver is that it will automatically uninstall conflicting software packages,
Some support software packages that need to be installed on the 3D desktop will automatically help you install them. For example, NVIDIA Glx software packages.
The association between these software is complex. It is troublesome and error-prone to manual installation.

First, make sure that you can connect to the Internet. In the graphic interface, click "System"-"System Management"-"software source" in the taskbar"
In the drop-down menu of "Download from" in the pop-up window, change the default "China server" to "master server ".
Click "close" and some files will be automatically updated.

Then, click "System"-"System Management"-"New Software Package Manager" in the taskbar"
In the menu bar, click "edit"-"Search"-enter envyng-GTK and select it. The system prompts you to install envyng-core,
Select the check box and click "application" to automatically download and install (If your Ubuntu has KDE installed, you can also download envyng-QT for installation ).
On the command line installation method, click "application"-"attachment"-"terminal" in the taskbar ",
Run the following command: sudo apt-Get install envyng-GTK
If you cannot access the graphic interface, you can also log on to the terminal after startup. Use this command to install envyng.

If it is a 64-bit CPU system, the system may prompt "/usr/lib32/libgl. so.1" error when installing envyng,
Solution: click "application"-"attachment"-"terminal" in the taskbar and enter the following command:
Sudo ln-S/usr/lib64/usr/lib32
Then install envyng to complete the installation.

After envyng is installed, envyng can be started in "application"-"System Tools" on the taskbar,
After the video is started, select "ATI" or "nvdia" based on your video card type in the box on the left ",
On the right side, we recommend that you select the default (Automatic hardware detection) to automatically detect hardware installation,
Click "application" to automatically download and install the official driver.

Because envyng has different versions, the 1.1.1ubuntu3 version of envyng-GTK has no graphic interface,
In this case, you can use the command line method to envyng to install the video card driver,
Click "application"-"attachment"-"terminal" in the taskbar and enter the following command: sudo envyng-T
Then there will be a menu, please select according to your graphics card needs:
1-install the NVIDIA driver to install the NVIDIA graphics card driver
2-uninstall the NVIDIA driver to uninstall the NVIDIA graphics card driver
3-install the ATI driver to install the ATI graphics card driver
4-uninstall the ATI driver to uninstall the ATI graphics card driver
5-restart the xserver restart x Service (graphical interface)
6-restart your computer
7-exit

Take the NVIDIA graphics card as an example. After "1" is selected, the following driver versions will be listed for installation:
0. 177.80-0ubuntu2
1. 173.14.12-1-0ubuntu4
2. 96.43.05-0ubuntu10
3. 71.86.04-0ubuntu10
Select "0" by default and press enter to automatically download and install the latest official driver,
After the installation is complete, you will be prompted whether to restart the computer, select "0 yes" to restart or "1 no" to restart.
If the video card driver of this version does not work after the computer is restarted, you can also choose 1, 2, 3... Try drivers of other versions.
If an error occurs during the installation process, such as a sudden power failure, you can use the following command to restore the status before the envyng installation:
Sudo envyng -- uninstall-all

(3) What if the black screen of the computer is restarted after the video card is installed?
Don't worry, simple task, huh, huh.
Press CTRL + ALT + F1 to switch to the terminal. Let's first find the problem, log on to the terminal, and enter the command:
More/var/log/xorg.0.log | grep "(EE)" and more/var/log/xorg.0.log
| Grep "(WW )"
The two commands mean to view the error (or warning) information when the GUI is started.

If there are not many output error messages and there are only one or two lines, you can copy them on a piece of paper.
What if there is a large string of output error messages? I copied it very tired.
Okay. Run the following command: More/var/log/xorg.0.log | grep "(EE)">
123
In this way, the error information can be saved in the 123 file,
After a while, we can go back to the graphic interface and find a solution or ask for help online based on the error message.

(4) When a new video card driver is installed, the screen is black. How can I return to the graphic interface? Can I use XP only?
Neither.
If you have installed the Ubuntu system and can use images by default, you can restore it to its original state.
Restart the system, and select (recovery mode) in the grub Startup menu, which is the second item.
My computer example is: Ubuntu 8.04.1, kernel 2.6.24-19-generic (recovery
Mode)
Then you can see a menu, select "Fix X" and press enter, and then select the first item to start normally.
Oh, is the graphic interface back?
After returning to the graphic interface, you can go online to find a solution or post for help based on the error message.

What? No menu available at startup?
This is because you did not check the "starter" Installation option when installing the Ubuntu system ".
What should I do? Installing grub is not covered in this article. Otherwise, it will be too long. You can find a method on the Internet.

(5) If everything goes well, the official driver of the video card has been correctly installed.
Take my computer NVIDIA as an example. The NVIDIA logo is displayed when the GUI is started,
You can use "nvidia x Server setting" in "System"-"System Management" in the taskbar.

In the taskbar "System"-"System Management"-"hardware driver" of ubuntu 8.04, NVIDIA is red and "not used.
In ubuntu 8.10, NVIDIA turns green, prompting that "the driver has been activated and used.

If other problems occur during video card installation, check the/var/log/xorg.0.log file,
Then, find a solution on the Internet. You may need to run some commands on the terminal,
Or you need to manually modify the/etc/X11/Xorg. conf file in the terminal. It is not difficult, don't be afraid,
The method for learning Linux is as follows: Find the error prompt-> find the answer or help on the Internet-> go back and follow the method.

(6) After the video card driver is installed, install compiz
Try a 3D desktop with fusion.
Click "System"-"System Management"-"New Software Package Manager" in the taskbar"

Click "Search" and select "compizconfig-settings-manager" and "Emerald" and "Fusion-icon" for installation;
After the installation is complete, how do I start the 3D desktop?
You can start "compiz fusion icon" in "application"-"System Tools" on the taskbar ",
Then, in the upper-right corner of the desktop, you can see a blue cube icon, right-click it,
Select "Settings manager" to bring up the special effect settings window.

Click "System"-"Preferences"-"session" in the taskbar. In the pop-up "add Startup Program,
Enter "name", "command", "Fusion-icon", and "comment;
Click "OK" to enable the 3D desktop effect automatically when the computer and Ubuntu are started.

(7) Has fusion-Icon been started, but no special effect is returned?
If you have added "Fusion-icon" to the "session,
First, check whether the/var/log/xorg.0.log file has an (EE) error or (WW) warning.
It is usually because of conflicts between the graphics card driver and some software packages that make 3D special effects unable to be started,
Find the log record, and then go online to find a solution, or post for help.

(8) How do I set the number of 3D desktops?
There is a post on the Internet saying that it should be changed in the general option (general) desktop size,
In fact, you don't have to worry about this. You just need to right-click "Current workspace" in the lower right corner and select "Preferences ",
In the pop-up window, adjust the number in the column to 4. I got 6 cubes with 6 edges.

To start the 3D desktop, you also need to check the 3D window in the effects (special effects), and the system will prompt "";
Check the desktop cube and rotate cube in the desktop to start the 3D desktop;
Press the scroll wheel to move up, down, left, and right to see the effect. Press CTRL + ALT + left to create the mouse.

(9) What should I do if a window has no border and no title bar?
In my experience, right-click the blue compiz fusion icon in the upper right corner of the desktop,
Select reload Window Manager (reload window manager) and refresh the desktop.
If the computer configuration is too low, the cup is not fast enough, and the memory is not enough, some problems may occur when running the 3D desktop.
If reload window manager still fails,
Right-click the blue compiz fusion icon in the upper-right corner of the desktop and select "exit ".
If the problem persists, log out or press CTRL + ALT + backspace to restart the graphic interface.

(10) How do I pause 3D effects?
Right-click compiz in the upper right corner of the desktop
Fusion icon,
Select metacity in select window manager. You can see that the number of desktops and wallpapers have changed.
To resume the 3D effect, select compiz in select Window Manager.

(11) How do I pause the emerald theme effect?
Right-click the blue compiz fusion icon in the upper-right corner of the desktop,
Select GTK window decorator in select Window decorator,
You can see that the border and title bar form of the window have changed back.
To resume emerald topic enabling, select emerald in select Window decorator.

(12) how to upgrade compiz
Fusion to 0.7.6 or 0.7.8?
View
Compiz fusion (CCSM) version:
Right-click the blue compiz fusion icon in the upper-right corner of the desktop,
Select "Settings manager" to bring up the special effect settings window. Click "Preferences" on the left ",
Click "about ccsm..." on the left of the following window to view the version number.

If your Ubuntu version is 8.04, you can upgrade compiz fusion to version 0.7.6:
Click "application"-"attachment"-"terminal" in the taskbar and enter the following command:
Add sudo gedit/etc/APT/sources. List in the last line:
Deb http://ppa.launchpad.net/compiz/ubuntu
Hard main
Then run the following commands: sudo apt-Get update and sudo apt-Get upgrade to automatically upgrade the instance.

If your Ubuntu version is 8.10 and the new compiz Fusion version is 0.7.8,
If you have just upgraded Ubuntu to version 8.10, You can manually upgrade compiz fusion to version 0.7.8,
Click "application"-"attachment"-"terminal" in the taskbar and enter the following command:
Add sudo gedit/etc/APT/sources. List in the last line:
Deb http://ppa.launchpad.net/compiz/ubuntu
Intrepid main
Then run the following commands: sudo apt-Get update and sudo apt-Get upgrade to automatically upgrade the instance.
If the above statement cannot be updated to the new version after execution, use the following statement: sudo apt-Get dist-Upgrade

Note that after the upgrade, some special effect settings will be different from the old version 0.7.4.

(13) how to set different wallpapers for each desktop?
First, click "application"-"attachment"-"terminal" in the taskbar and enter the following command:
Gconf-Editor (note that sudo is not required for this command)
Then, on the left of the pop-up window, open it at the first level (just like changing the Registry in Windows)
Apps -- Nautilus -- preferences find the show_desktop item in the right window and deselect it.
Although this will make GNOME desktop icons invisible, right-clicking on the desktop does not respond,
However, this has little impact on the actual application. It's just a habit of everyone. Then ......

Version 0.7.4:
Under appearace In the desktop cube in desktop,
Add multiple images in background images.
0.7.6 and 0.7.8:
In the wallity (Tool)'s wallpaper (wallpaper), click "new" to add n images.

(14) How do I set the wallpaper on the top, bottom, and rotating the background?
This new version is different from the old version. Version 0.7.4 is set in cube caps,
In version 0.7.6 or 0.7.8, why does cube caps disappear?
Haha, it is broken down. There is a part of apperarance In the desktop cube,
Expand skydome to set the wallpaper of the skydome image rotation background.
In the effects (special effect) Cube reflection and deformation, there is another part,
Expand the "appearance" of cube caps to add top image files and bottom image files,
By default, the image is zoomed in and filled in. You can modify the zoom function in the following "action.

(15) how to change a 3D desktop cube into a cylindrical or sphere?
First, upgrade to version 0.7.6 or 0.7.8.

In deformation in cube reflection and deformation of effects (special effect)
There is a drop-down menu, "NONE" is the cube, cylinder is the cylinder, sphere is the sphere.

(16) I don't have a camera. How can I record my 3D desktop animation to my friends?
There was an article on the Internet titled "Five Linux screen recording methods". I tried three of them.
It seems difficult and complicated to record 3D desktop animations?
Haha,! After finding the solution, I found that it was so simple!
-- This is also the charm of Linux.
-- But this is indeed the result of dozens of failed attempts.

Click "System"-"System Management"-"New Software Package Manager" in the taskbar"
Select "Search" and install "recordmydesktop" and "GTK-recordmydesktop", respectively ",
After installation, you can start and run it in "application"-"audio and video" on the taskbar.
Ubuntu version 0.3.6 is installed by default.

Note the following when you start the recordmydesktop window:

A. To reduce system resource consumption, you can cancel the sound quqlity check,
In addition, the video quality can be reduced to 40.
Now click the red "Recording" button. How can this problem be solved? In the upper-right corner of the desktop, there is also a red "Recording" button,
Click on the white-colored four-party button at the upper right corner of the table to stop and then get an out.ogg file at the table,
(For version 0.3.7.3-1, the file name is out. OGV)
Double-click the file to call the audio/video player.

What's the problem? I only saw the special plane effect. Can I record the 3D effect? Don't worry. Continue:

B. in advanced performance,
Change frames per second to 25 or 30, that is, the conversion rate is the same as the speed required by normal films.
Set full shots at every frame to enabled (if it is version 0.3.7.3-1, check ).
Try recording again?

Another problem? I was able to record 3D effects, but it was intermittent, so it was not good to stop? Haha!

C. The most important thing! That is, the solution I found after dozens of failed attempts!
Right-click the blue compiz fusion icon in the upper-right corner of the desktop,
In compiz options, deselect the check box before indirect rendering!
Record the video and see if it is smooth?

D. The recorded Ogg (or OGV) file cannot be played in windows. What should I do?
By default, Media Player in Windows cannot recognize the Ogg (or OGV) format, and cannot play,
Kmplayer also does not recognize the file name, but can play, drag the file into kmplayer.
But if you want to use Adobe Premiere Pro 2.0 for editing, or upload a video website in China,
The format must be converted,
I used mencoder and FFMPEG to convert Ogg (OGV) to Avi or MPEG,
However, in windows, media player cannot be used for playback, and premiere cannot be used for editing.
Later, I finally discovered a software total Video Converter 3.12 Chinese version,
It can be converted to the WMV format for Windows playback. The screen is reduced a little bit, and the effect is good.
That is, the file size is increased by about 50%,
