Ubuntu14.04 has some common sense and some minor problems, while ubuntu14.04 has some minor problems.

1. Always get stuck after the screen lock

This is a bug because ubuntu14.04 is not stable.

Solution: Disable the brightness & lock settings in system setting.

You can only turn off the screen without locking the user, that is, no password is required for wake-up.

2. After ubuntu14 is installed, google Pinyin is available by default. You can use ctrl + space to switch.

Ubuntu14.04 install sogou input method and configuration (solution to invalid shortcut keys)

Its linux version supports the deb package of 14.04 by default, which can be downloaded at http://pinyin.sogou.com/linux/

The deb package integrates the fcitx Input Method Framework. After downloading deb, run the input method program (im-config) on the dash panel, click "OK"-"Yes", select fcitx, and click "OK.

After logging out of the system, you can find that the keyboard shortcut for ctrl + space is invalid because the ibus and fcitx shortcuts conflict.
On the dash panel, find "system settings", enter "text input", and modify "shortcut to the next source". Do not set it to ctrl + space or ctrl + shift, click ctrl + space again to switch the sogou input method.

3. the built-in software is still very useful. Terminal input gnome-screenshot-

Help options:
-H, -- help display help options
-- Help-all: display all help options
-- Help-gtk: Display GTK + options

Application options:
-W, -- window captures the window, not the whole screen
-A, -- area captures an area of the screen, rather than the whole screen
-B, -- include-border: The screenshot contains the window border.
-B, -- remove-border remove the window border of the screen
-D, -- delay = Second: capture the image after the specified delay [in seconds]
-E, -- border-effect = special effect (shadow, border, or no special effect)
-I, -- interactive setting options
-- Display = display the X to be used

For example, press Ctrl + Alt + A to implement the region.
Go to system> preferences> keyboard shortcut to add

In the command (Command), Enter gnome-screenshot-.
(Name) name Customization
Then, set the shortcut key to OK.

Note: The shortcut keys here are somewhat high-end. See the reminder in the last row and select the corresponding row. ClickDisabledIn this case, it will change to another word. Then you can enter a new key combination.

14.04 has CTL + shift + printFull Screen.

4. eclipseThe menu bar of is invalid.

Solution: Create a shortcut

Create an eclipse. desktop and enter the following code on the terminal:

Sudogedit/usr/share/applications/eclipse. desktop

Add the following content to the file, save and exit.

5. eclipseStartup Error, JrePath Problems

The reason for this problem is that I am ~ /. The Java environment variable in bashrc. This file will be read when you start the terminal, but it is not global. Therefore, the jre cannot be found by double-clicking.

6. Install flash with chromium

sudo apt-get install pepperflashplugin-nonfree

sudoupdate-pepperflashplugin-nonfree --install

After installation, you can watch videos and listen to music. However, Baidu music does not work. Once all the web pages are opened, the system crashes.

6. Install flash in firefox. I am using Ubuntu software to install flash slowly.

7. Incorrect dual system time

Some time ago, during Windows system time, the machine was not connected to the Internet. During the boot every day, the system would be slow for 8 hours. I don't know what's going on, because I was busy with other things, so I had to find the reason after a few days, later I found that the windowstime service was not automatic, so I think this is the reason.
No exception was found after several times of use, because no network cable was inserted when the system was started up today and it went directly into ubuntu. It took nearly 8 hours to plug in the network cable, so I thought it was not normal, so I restarted Windows 7 and found that it was 8 hours slow, so I realized that the two systems may have different settings, resulting in this time problem. So google:
Two concepts:
UTC is UniversalTime Coordinated, Coordinated Universal Time
GMT is GreenwichMean Time, Greenwich Mean Time

By default, Windows and Mac/Linux are different in terms of system hardware time:
Windows treats the system hardware time as localtime, that is, the time displayed in the operating system is the same as the time displayed in the BIOS.
Linux/Unix/Mac uses the hardware time as UTC, and the time displayed in the operating system is converted by the hardware time. For example, Beijing time is GMT + 8, the time displayed in the system is hardware time + 8.
In this way, a problem occurs when multiple systems coexist in the PC.
Assume that all the time zones configured for ubuntu are UTC + 8 (Beijing Time). The current system time is AM. In this case, the hardware actually stores the UTC time AM. After you restart and enter Windows, you will find that the time displayed in windows is AM, eight hours slower than in ubuntu. Similarly, after you change the system time in Windows or use the network to synchronize the system time, and then go to Ubuntu to see it, the system will be 8 hours faster. The situation may be more complex in the region where renewal is implemented.

Solution:
1. Ensure that Ubuntu does not use UTC time consistent with Windows.
By default, UTC is enabled for ubuntu, that is, Coordinated Universal Time, while win7 uses this timing method. This results in a difference in time computing between Windows and Ubuntu.
You can use the following method to get the same time:
Sudogedit/etc/default/rcS
Find this line: UTC = yes
Change yes to no

2. Modify the way Windows treats hardware time, so that you do not need to set it on Ubuntu only after modification on Windows.
Let Windows treat hardware time as UTC
Start-> Run-> CMD, open the command line program (Vista needs to open the command line program as an administrator to have permission to access the Registry), enter the following command in the command line, and press ENTER

Code:

Regadd HKLM \ SYSTEM \ CurrentControlSet \ Control \ TimeZoneInformation/vRealTimeIsUniversal/t REG_DWORD/d 1

Method 1: The test is effective.

8. Install chrome.

Ubuntu14.04 comes pre-installed with two browsers: chromium and firefox

However, the two software must install the flash plug-in again, and sometimes the video in the nba Chinese network cannot be played. I don't know why.

It's amazing to install chrome.

The following describes how to install chrome.

Method 1: Download The. deb installation package directly from the official website.

Https://www.google.com/intl/en/chrome/browser/This website does not seem to be accessible.

You can use command lines instead.

32-bit version

wgethttps://dl.google.com/linux/direct/google-chrome-stable_current_i386.deb

64-bit version

wgethttps://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb

After the download, you can start the installation.

Use the following command for 32-bit and 64-bit installation:

sudo dpkg -igoogle-chrome-stable_current_i386.deb

sudo dpkg-i google-chrome-stable_current_amd64.deb

In this step, I read Baidu's experience and said, "The dependency problem requires $ sudoapt-get install-f to be fixed." I don't know what the problem is, I have never encountered any problems.

Method 2: Use google's official chromePPA for Installation

Run the following command on the terminal to download and install the signature key from googlelinux repository.

wget -q -O -https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-keyadd -

After installation, add googlechrome repository

sudo sh -c 'echo "debhttp://dl.google.com/linux/chrome/deb/ stable main" >>/etc/apt/sources.list.d/google-chrome.list'

Finally, update your resource library and install chrome

sudo apt-get update

sudo apt-getinstall google-chrome

If you want to use the test version, use sudoapt-get install google-chrome-beta.

There is also an unstable version: sudoapt-get install google-chrome-unstable
