### Ly - ncurses display manager
|
||||
|
||||
|
||||
|
||||
This is a lightweight login/display manager for linux made with ncurses.
|
||||
It is based on linux-pam and systemd and was developped in good old C99.
|
||||
This program was designed to be simple, modular and highly configurable.
|
||||
Ly was made for crazy people. If you're not insane, run away.
|
||||
|
||||
### Configuration and installation
|
||||
Ly tries not to reinvent the wheel and uses linux-utils and xorg-xinit
|
||||
instead of providing heavy, incomplete and outdated implementations.
|
||||
Make sure all the following tools and libraries are available on your
|
||||
distribution before going further:
|
||||
- make
|
||||
- a c99 compiler
|
||||
- systemd
|
||||
- linux-pam
|
||||
- ncurses
|
||||
- tput
|
||||
- libX11 (required if you wish to use X)
|
||||
- xorg-xinit (required if you wish to use X)
|
||||
- xorg-xauth (required if you wish to use X)
|
||||
- mcookie (required if you wish to use X)
|
||||
|
||||
You can now configure Ly by editing "src/config.h". Modify "ly.service"
|
||||
as well if you changed the default tty, then build the executable:
|
||||
```
|
||||
make
|
||||
```
|
||||
Check if it works on the tty you configured (default is tty2). You can
|
||||
also run it in terminal emulators, but desktop environments won't start.
|
||||
```
|
||||
sudo build/ly
|
||||
```
|
||||
Then, install Ly and the systemd service file:
|
||||
```
|
||||
sudo make install
|
||||
```
|
||||
Now enable the systemd service to make it spawn on startup:
|
||||
```
|
||||
sudo systemctl enable ly.service
|
||||
```
|
||||
If you need to switch between ttys after Ly's start you also have to
|
||||
disable getty on Ly's tty to prevent "login" from spawning on top of it:
|
||||
```
|
||||
sudo systemctl disable getty@tty2.service
|
||||
```
|
||||
If messages from other services pops-up over the login prompt, you have to edit the service in order to run it last. In order to do this, simply edit the following file:
|
||||
```
|
||||
/usr/lib/systemd/system/ly.service
|
||||
```
|
||||
Just under the "After getty", add another one with your last-launching service. Example on my computer:
|
||||
```
|
||||
After=tlp.service
|
||||
```
|
||||
|
||||
### Controls
|
||||
Use the up and down arrow keys to change the current field, and the
|
||||
left and right arrow keys to change the target desktop environment
|
||||
while on the desktop field (above the username field).
|
||||
|
||||
### Additionnal informations
|
||||
The name "Ly" is a tribute to the fairy from the game Rayman.
|
||||
Ly was tested by oxodao, who is some seriously awesome dude. (you rock!)
|
||||
I wish to thank ncurses, linux-pam, X11 and systemd developers for not
|
||||
providing anything close to a reference or documentation.
