How to configure KDE4

The basic configuration method of KDE4-Linux general technology-Linux technology and application information. For details, refer to the following section. The first installation of kde4 has many problems. After several reinstallation and adjustment, I finally got a stable environment. I hope the following methods can help my friends who have encountered problems.

The simplest kde4 installation method:

Use (k) ubuntu to change the source gusty to hard. After update

Sudo apt-get install kde4 kde4-desktop

Restart the instance. If you want to use a Chinese environment, we recommend that you use a CD to install the Language Pack. We do not recommend that you install the language pack from the source. The current language pack is not complete yet, and many bugs have emerged. Some Chinese characters are displayed as the origin, which affects usage.

Desktop effect cannot be started after installation: Install the linux graphics card driver provided by the video card manufacturer. For details, see the instructions on the vendor page.

If the desktop effect is selected, the result is a black screen:

Restart. Press ctrl + alt + F3 to enter the console on the 3rd to install the gmtr and gnome-desktop. After restart, enter Gnome, install xgl, and enable a kde desktop in xgl:

Xgl: 13-ac-screen 1024x768 & DISPLAY =: 13/usr/lib/kde4/bin/startkde

After entering the desktop, check the desktop effect again. Special effects can be used in xgl. By the way, you can also see

After entering kde4, you can consider deleting or retaining the gnome Desktop.

If the syntax on command is configured in vimrc, the following error occurs:

Install vim-full to replace vim.

No sound:
This is a possible problem.

1. There is no sound at the first startup, and no sound card is listed in Phonon.

Create/etc/asound. conf and write the following content:
Pcm. softvolPhonon {
Type softvol
Slave. pcm "default: CARD = 0"
Control {
Name "Phonon"
Card 0
}
Min_dB-51.0
# Max_dB 0.0
Resolution 100
Hint {
Show on
Description "My Soundcard with extra Volume Control"
}
}

Restart and try again.

2. There was sound at the beginning of installation, but after dist-upgrade several times, or after the software was installed, there was no sound.

Install the kmix-kde4 and then use the following command:
Sudo kmix -- keepvisibility

The kmix mixer is enabled. Remove all mute check boxes and try again.

3. The Playing Sound causes a crash.
It may be caused by a conflict with the xine plug-in. Delete the xine conflict Plugin:
Sudo rm/usr/lib/xine/plugins/VERSION/xineplug_ao_out_pulseaudio.so

Replace the VERSION with your VERSION. Generally, click a tab.

4. I have done the above, but I still have no sound.
Try to add your users to the audio group:
Sudo usermod-G audio your_username

Note: sudo may be unavailable in the future.

5. The Phonon player device is incorrect, or prompts you to find a usb or something.

Currently, there is no solution. We recommend that you follow the latest bugs.kde.org method.

When playing a video, there is sound but no image:
Cancel the desktop effect and try again. It has been confirmed that opening the desktop will cause no images for players such as kaffeine.

No input method:
Run the following command to install scim-bridge, scim-pinyin, and im-switch:

Im-switch-c

Select the number before scim-pinyin. Then change/etc/X11/xinit. d/xinput. d/scim-pinyin

Change all = xim to = scim-bridge.

Restart.

After installing any software, there is no shortcut in the menu. Restart. This is surprising.

The manual configuration in Network Manager is invalid: I did not find a solution to this problem. I chose to directly write the/etc/network/interfaces file.

For more information, see man interfaces.

After adjusting and solving these problems, my kde4 desktop can now undertake daily work tasks. If the font is uncomfortable, use the font installer to install the font and recache the font cache before calling it. Write so much first, hoping to be helpful to friends who love kde.
