Q1: How to view the operations of system and applications (Deepin Manual)?

A1: Press the F1 shortcut key ( or click Help in main menu) on the desktop, control center, launcher, and deepin applications to call up Deepin Manual.

Q2: What should I do when I have problems?

A2: First, search in Wiki (https://wiki.deepin.org/ ) and the community (https://bbs.deepin.org/module). If there was no answer, execute

sudo deepin-feedback-cli

Copy the Code

to generate a log file (tar.gz) in home directory (please do it right after the problem occurs), and attach it to deepin feedback (http://feedback.deepin.org/).

Q3: How to solve the eight hours time difference between deepin and Windows?

A3: The reason is that Windows and Linux have different standard time for hardware. Windows defaults to local time, while Linux defaults to UTC time, so it will be 8 hours difference. The solution is to change Windows to UTC time.

Run in Deepin Terminal:

Sudo hwclock --systohc --localtime

Copy the Code

Enter the password and press Enter. The time will be changed. Reboot Windows to check it.

Q7: How to fix it if the Wifi signal is poor or disconnected frequently or the wireless network cannot be found in network module?

A7: Try to turn off Bluetooth and wireless screencast at first. Then execute "sudo deepin-feedback-cli" command to generate a log file (tar.gz) and attach it to deepin feedback (please do it right after the problem occurs).

2. Visit https://github.com/lwfinger/rtlwifi_new on a computer that network connected, find if there is your network card number. If there is, click the green button at the top to download ZIP file.

3. Copy the zip file to network-disconnected PC.

4. Unzip the file and right click in the folder to open terminal, then run the following commands:

make
sudo make install
sudo modprobe rtl8723be #your network card number

Copy the Code

5. Reboot and you will find the WiFi is connected.

For network card in other brands, please find their Linux driver and do as above ways or read the driver instructions.

Q8: How to solve the download failure in Deepin Store?

A8: First, please run the command

sudo gedit /etc/apt/sources.list

## Generated by deepin-installer
deb [by-hash=force] http://packages.deepin.com/deepin panda main contrib non-free
deb-src http://packages.deepin.com/deepin panda main contrib non-free

If not, delete the differences and save. Run "sudo apt-get update && sudo apt-get dist-upgrade", and then install apps again in Deepin Store.

Hello. I'm trying Deepin, and I really loved its desktop environment. It is very good. But while trying, I put the computer into sleep. after wake up, it asks for live user password. And we don't know it.What is the live user password? I tried "live" "deepin" "user" etc. none of them worked.
