You need to output to the dmix ALSA device instead of the default device; that allows multiple streams to be mixed and output to the sound card. It is set up automatically on sound devices which don’t support hardware mixing; as you can see, it’s set up on your system. You’ll find more information on the ALSA wiki. You can configure dmix to be the default ...

It's apt-key add - apt-key the command and add the subcommand/option (you might be confusing it with add-apt-repository). This is for adding a key from a file. If you want to fetch a key and add it, you need apt-key adv --recv-key: adv Pass advanced options to gpg. With adv --recv-key you can e.g. download key from keyservers directly into the the ...

While deepin OS is based on debian (unstable), it would seem that installing the deepin desktop environment (DDE) is not supported. As far as I can see, there are no pre-compiled repositories for debian for easy installation. There is however support for other distros such as Ubuntu and Manjaro with repositories as detailed on Desktop Translation deepin page....

The filesystem going readonly by itself is very likely the result of the filesystem driver encountering errors. You might see the errors=remount-ro option in the output of mount. It does that to protect the filesystem from further issues. (The alternatives are to continue and ignore the error, or to panic the system, see ext4(5)). You should probably see ...

The repository only accepts key verification when cloned over ssh. Either modify the repository's setting if you have access to, or clone over HTTPS. To be more specific. I have successfully cloned the repository by running git clone https://github.com/user23a/dde-dock.git

Many Noto fonts report to the system that they support the Arabic script, which they do—in part. One of these fonts is the Urdu font, and for whatever reason it has the priority over other fonts that support the Arabic Script. You can prefer a specific font over the others as follows: <?xml version="1.0"?> <!DOCTYPE fontconfig SYSTEM "fonts.dtd"&...

The header files in /usr/include/x86_64-linux-gnu/bits/ are included by a corresponding header in /usr/include/. If I open up /usr/include/utmp.h on my machine and go to lines 28 and 29, I'll find: /* Get system dependent values and data structures. */ #include <bits/utmp.h> This means that the bits headers are used to define data structures and ...

As seen in the file /usr/share/applications/dde-control-center.desktop, the Exec line is Exec=dbus-send --print-reply --dest=com.deepin.dde.ControlCenter /com/deepin/dde/ControlCenter com.deepin.dde.ControlCenter.Show Using Toggle instead of Show would better serve our purpose. So, create a new shortcut with the command dbus-send --print-reply --dest=com....

Since Deepin 15.10, the base kernel is Debian stable, but in the Deepin distribution template is set as unstable; let's change that. sudo nano /usr/share/python-apt/templates/Deepin.info change Suite: unstable to Suite: stable and voilá, you now can add PPA ...

You should be able to add the repository manually. Something like this: curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add - printf 'deb [arch=amd64] https://download.docker.com/linux/debian stretch stable\n' \ | sudo tee /etc/apt/sources.list.d/docker-ce.list

There might be an issue with the lightdm-deepin-greeter. Install an alternative greeter, e.g lightdm-gtk-greeter sudo pacman -S lightdm-gtk-greeter Then edit /etc/lightdm/lightdm.conf sudo nano /etc/lightdm/lightdm.conf Look for the line that is like greeter-session=lightdm-deepin-greeter or the value could be something else change it to greeter-...

The -e option for deepin-terminal, as for most terminal emulators, takes a simple command. A pipeline is not a simple command. The error comes from the terminal trying to execute a command with the literal name cmatrix | lolcat (including spaces and pipe symbol). Instead, use deepin-terminal -m fullscreen -e sh -c "cmatrix | lolcat" This would execute ...

Install / Open Deepin Graphics Driver Manager and Select NVidia in that. Reboot and again boot back to ...

There is an easier (and probably also better) way to this using gsettings. I suggest using the dconf-editor to modify gsettings. It is also possible to do the following from the command line directly via the gsettings command, but the visual editor is much simpler. The following is the set up for Fedora, tested on Fedora 30: 1) Get the dconf-editor: ...

I haven't found a keyboard shortcut yet. However, if you have a touchpad you swipe sideways with three fingers. This way the focused window docks to a side of the screen. If somebody finds a hotkey i would still be happy to know about it!

These are different choices in Deepin and Ubuntu regarding security vs usability vs stability. Installing software requires administrative privileges. Ubuntu prompts for your password for anything that requires administrative privileges, Deepin doesn't.

You have an outdated apt-get index. One of the dependent packages can no longer be found. You're on unstable so this ought to happen from time to time. Checking the files on that server reveals that the latest version of the file that apt-get install tries to fetch is liblua5.2-0_5.2.4-1.1_amd64.deb (updated on the 3rd of June 2016), not liblua5.2-0_5.2.4-...

Have you looked at what is running? Most desktops ship a process monitor but failing that, htop even top in the command line will show you what is currently using CPU. If you have a case where it stops using CPU every time you look at it, you can log output over time with pidstat. Run pidstat -u 600 and leave your laptop to idle for 10 minutes . When you ...
