The X-Server is started by using the two systemd units ~xlogin@.service~ and ~x@.service~ provided by the package *xlogin*. The former is enabled (and started) for the vdr user - which results (using the default settings for the user *vdr* with the uid *666*) in the activation of ~xlogin@vdr.service~ when reaching the graphical.target. To simplify starting and stopping the X-server and the desktop session a ~yavdr-xorg.service~ is provided by the package ~yavdr-xorg~, which depends on the two units mentioned before.
|
||||
|
||||
~x@vt7.service~ is started automatically as a dependency of ~xlogin@vdr.service~ and starts the X-server. ~xlogin@vdr.service~ also starts a systemd user session using ~user@666.service~.
|
||||
In order to use the keyboard layout configured during installation for the X-Server the script ~write-x11-keyboard-config~ reads the keyboard configuration from ~/etc/default/keyboard~ when starting ~x@.service~ and writes the file ~/etc/X11/xorg.conf.d/00-keyboard.conf~ (because systemd for Ubuntu (and Debian) has been patched not to create ~/etc/X11/xorg.conf.d/00-keyboard.conf~ according to the ~localectl~ settings).
|
||||
In order to use the keyboard layout configured during installation for the X-Server we are using a script ~write-x11-keyboard-config,~ which reads the keyboard configuration from ~/etc/default/keyboard~ when starting ~x@.service~ and writes the file ~/etc/X11/xorg.conf.d/00-keyboard.conf~ (because systemd for Ubuntu (and Debian) has been patched not to automatically create the configuration file ~/etc/X11/xorg.conf.d/00-keyboard.conf~ according to the ~localectl~ settings).
|
||||
|
||||
To prevent stopping the X-server when vdr is running, additional dependencies are set up - see the drop-in rules created in ~/etc/systemd/system/vdr.service.d/~.
