Q: Why the system does not auto-mount Win partitions?
A: The reason is auto-mount frequently results in failing to boot. Win 8/Win 10 enables "Fast Startup" by default, which will cause boot failure for Linux operating system. Thus it is not recommended to mount them by default.

Q: Why not enable keypad by default?
A: Due to some driver issues, some computers will be unable to use keypad after booting.

Q: Why the system time is wrong in Windows (8 hours differ from the correct time)?
A: That is due to the difference in hardware standard time settings between Windows and Linux. Switching to UTC time in Windows can solve this issue.

Download in Windows  , double click and import to Register, then reboot and it is done.

Q: How to uninstall an application?
A: Enter Launcher, right-click the application, and select uninstall.

Q: How to set wallpaper?
A: Currently, "Control Center——Personalization" is not featured with wallpaper adding (there will be). Please open the wallpaper with image view, then right click to set as wallpaper.

Q: Why there is no search in Launcher?
A: There is search in Launcher (without interface), directly input characters in Launcher interface to search.

Q: There is no suitable resolution.
A: Currently, we haven't optimized resolution for HiDPI screens, so there is no suitable resolution for them.
If your monitor is not HiDPI but still no suitable resolution, maybe it is due to graphics driver, it can not be solved for now.

Q: How to set environment variables?
A: We use lightdm as login manager, so set environment variables in "/etc/X11/Xsession.d".

Q: How to enable Wi-Fi hotspot?
A: Currently the system does not provide this feature, but not all network cards support this feature.

Q: Where is system update?
A: System update is in "Control Center——System Information".

Q: How to set mirror for the system?
A: Please run "Control Center——System Information——Update——Settings (small gear)——Switch".

Q: Why errors occurred when adding PPA?
A: deepin 15 and later editions are based on Debian, so it does not support Ubuntu-only PPA.

Q: Why I can not log in with the correct password and always goes back to login interface?
A: This issue can be caused by many reasons, please judge on your own: Type A: Configuration file went wrong. Please switch to TTY1 with "Ctrl + Alt + F1" in login interface. How to login with your account (touch input your password and enter, the password will not echo). How to execute:
rm ~/.Xauthority

How to log in after switched back to login interface by "Alt + F7".

Type B: /tmp permission error. Please switch to TTY1 with "Ctrl + Alt + F1" in login interface. How to log in with your account (touch input your password and enter, the password will not echo). How to execute:
  1. sudo chmod -R 777 /tmp && sudo chown root /tmp
Copy the Code
How to log in after switched back to login interface by "Alt + F7".

Type C: not enough space in /home partition, please enter Live CD mode to transfer files or use command line to delete unnecessary files.

Q: Why the system suddenly can not normally booted?
A: It could be due to insufficient space in /boot partition, the only way is to enter Live CD mode and clean /boot partition.

Advice: Do not separately assign /boot partition while installing, let the system manage.

Q: Why there is no refresh function when right clicking mouse button on desktop?
A: This function will not be added, because it is meaningless in Linux.

Q: How to enter Live CD mode while installing the system?
A: Enabling Live CD mode will cause some computer that have driver issues unable to install the system, so by default Live CD mode is off.

To enable Live CD, enter the system installation interface, press "Ctrl + Alt + F1" to switch to TTY1, then log in with account "deepin" without password, then execute:
  1. sudo service lightdm restart
Copy the Code
Use "Alt + F7" to switch to GUI (TTY7) to enter Live CD mode.

Q: How to transfer files with Bluetooth?
A: Currently, this function is not provided in the system, and possibly will not be added in the future. It is slow to transfer files through Bluetooth, and of large power consumption. We plan to add LAN file transfer in our new file manager to solve this issue.

Q: How to connect to devices that need Bluetooth pairing code?
A: We are working on that.

Q: I have finger prints login on my computer, how do I enable it?
A:  Due to driver issues, it is not supported yet.
Q: How to enable direct login as root? A: First of all, it is really dangerous to directly log in as root, even Linux experts would not do that. And there is not much difference between logging in as root and normal user, so in case of safety, we would not provide this feature.
If you need to run a software as root or change system settings, all you need is to add sudo in front of the command line.

Q: I have installed Windows and Linux, how to change the default booting system?
A: Please set in "Control Center——Boot Menu".

Deepin Applications

Q: After installing close source graphics card driver, Deepin applications (such as Deepin Movie) can not run, why?
A: The front-end interface of some Deepin Applications are coded in QML, which is not compatible with close source graphics card driver, thus results in failure, and there is no solution yet.

Q: Why I can't input password in Deepin Terminal?
A: For safety reasons, input password in terminal would not show, so just touch input and press enter.

Q: How to switch dock mode?
A: Right click on the panel of dock, and set in the pop-up menu.

Others

Q: Why some applications (Windows applications) can not run by CrossOver?
A: Currently, CrossOver (Wine) can not perfectly run all Windows applications.

Q: Why there is no progress indication while copying files in file manager?
A: The progress indicating right button has been changed to the progress circle in the upper-right corner of the file manager. The current file manager is not developed by us, so we can not change it, please wait for ours.

Q: How to solve font missing in WPS?
A: Due to the copyrights of some fonts, WPS can not preinstall them. You can choose not to install them unless necessary.
Click here to solve the issue. But make sure you have copyright to these fonts (You only need to have an authorized Windows).

Q: How to install anti-virus program and firewall?
A: Due to the permission mechanism of Linux, very few virus can cause actual damage, common users can choose to not install anti-virus program or other safety software. If you want to install, you can check in Deepin Store.

Q: How to defrag disk?
A: Linux generates much less disk frags than in Windows, so it is unnecessary.

Foreword
When you post in deepin forum for help, you will get help to solve your problems effectively if you pay attention to the following points!        
Of course, if you have enough time, we recommend that you read: How To Ask Questions the Smart Way.



Preparations for Asking Questions  
[1] Make Good Use of Wiki
For common problems, such as those on system installation, system management and software, the complete documents are provided in deepin Wiki. Maybe you should read them first of all.  

[2] Make Good Use of Search
When you encounter a new problem, you should search for the relevant content in deepin forum or Google first of all since it’s very likely that it has been answered by someone.

Correct Manners of Asking Questions   
[1] Correct Sections
Send posts for help in correct sections, which is the basis of getting answers quickly!
Sections where you can send posts for help:   


[2] Use Appropriate Titles
Do not use titles which have nothing to do with your question, such as "Urgent, Waiting Online!!! ".  
In contrast, you should use titles that are related to your question, such as the title "Chrome Cannot Start, Error Info xxx" which is clear and concise and will receive more attention and discussion.

[3] Detailed Description
The more detailed the description is, the more helpful it is for others to help you solve your problems. Of course, the description need to be valid.  
First of all, you need to provide the following information:
  • A description of the problem:
  • Steps of reproducing the problem:
  • Frequency of occurrence of the problem:
  • Other basic information:

If, after discussing with forum members, you found a general Bug. Then please submit it with Deepin User Feedback in Launcher, it will go into Bug Tracking System, we will fix it as soon as possible!


When the terminal prompts you to enter a password, please touch type the current account and password and press “Enter”. You can finish collecting the information after waiting a moment.
You only need to upload the zipped package files generated in the home directory to the post.

[4] Use Images to Explain
An image is worth a thousand words. When you encounter a problem that is hard to explain, please upload the screenshot or video directly.  

[5] Neat Layout
Please make reasonable use of font sizes, font colors and set the content well.  
Clean and neat layout is convenient for others to understand your problems. The messy posts are very likely to be left unattended.   

Incorrect Manners of Asking Questions   
[1] Do Not Ask Questions by Following Others' Posts  
We suggest that you do not do this because it would disrupt other people's posts and your question would be likely to be buried if you did this.  

[2] Do Not Ask Questions by Sending PM
deepin community members, especially those active ones are very friendly!
It’s certain that your post for help will be seen by others, so it’s certain that we will reply those questions we can answer.  
In addition, there is nothing that we need communicate with others secretly, so please use posts to communicate. You might even help others who have similar questions.

[3] Do Not Use a Questioning Tone  
First of all, you will annoy others by doing so, and thus your problems will not be solved naturally.   
At the same time, we do not owe each other anything, so there is no reason to question others.  

[4] Do Not Make Your Question Sticky Yourself
Do not resend the same post or reply your own post to make your question sticky. You will annoy others by doing so, and your problems will not be solved.   
As for why no one gives you an answer, please see [2] Do Not Ask Questions by Sending PM.

What You Are Hoped to Do
[1] Thank Others
Do thank those who helped you please!  
Learn to be thankful, which is very necessary.   

[2] Help Others
You are welcome to help others actively. This is the tradition of the open-source communities. Of course, this is also the secret reason why the open-source communities have been prosperous since the beginning!
