Components
Display server (=X Server?)
Responsible for the graphical environment.
Implementations: Xorg (which is the popular in the
Linux community), XFree86 and X11.
An X Server implements X11 (a network protocol)
The X Server is responsible for
- managing resources
- processing drawing requests
- dispatching events (keyboard, mouse etc)
Display manager
If the system starts up, this is the first program (after running the display server?)
The
display manager allows a user to login in (hence, the display manager is also known as »login manager«).
When the user is logged in, the display manager starts an X-Session.
Desktop environment
A
desktop environment tries to create a consistent experience for the user. Thus, it ships with a set of applications that are all written using a common widget toolkit and set of libraries.
VcXsrv
I don't like installers, therefore, I want to extract the content of the VcXsrv installer. First, the installer is downloaded to ~/Downloads. Then:
$ mkdir /mnt/c/Users/Rene/vcxsrv
$ 7z x -o/mnt/c/Users/Rene/vcxsrv vcxsrv-64.1.20.14.0.installer.exe
Adding the address of the connecting client to C:\Users\Rene\vcxsrv\X0.hosts (in order to prevent the Authorization required, but no authorization protocol specified error message when starting an X client.
Then: start the server
C:\users\rene\vcxsrv\vcxsrv.exe" :0 -multiwindow -clipboard -wgl
Unblock the firewall to allow x-clients to connect to VcXsrv:
PS C:\> get-netFirewallRule -displayName vcxsrv.exe
PS C:\> set-netFirewallRule -displayName vcxsrv.exe -action allow
Now, on the Linux side (192.168.0.89 is the Address of the Windows Machine whre VcXsrv is running):
$ export DISPLAY=192.168.0.89:0
$ xterm
