* Fix ioctl issues on DragonFly BSD and FreeBSD
* Include the correct headers on DragonFly BSD and FreeBSD.
* Use UTF-8 characters to draw border on Linux.
* Use ioctl 'KDGETLED' to get the keyboard LED states, which is supported
on both Linux and BSD.
* Use macros 'LED_NUM' and 'LED_CAP' instead of hard-coded magic numbers.
NOTE:
This patch only allows 'ly' to build fine on DragonFly BSD and FreeBSD
(other *BSD not tested), and more works are needed to make 'ly' working
fine on BSD.
* Use ioctl 'KDGKBLED' on Linux
The legacy ioctl 'KDGETLED' (which also exists on BSD) is used to get the
state of keyboard LEDs, which, however, can be used to display arbitrary
information! So the new ioctl 'KDGKBLED' should be used to get the keyboard
flags (CapsLock, NumLock, ScrollLock), and this ioctl has a separate set of
macros ('K_NUMLOCK', 'K_CAPSLOCK') to check the flags.
See the ioctl_console(2) man page for more details.

Ly - a TUI display manager
Ly is a lightweight, TUI (ncurses-like) display manager for Linux.
Dependencies
Make sure all the following packages are properly installed and configured before going further:
- a C99 compiler (tested with gcc and tcc)
- a C standard library
- make
- linux-pam
- xorg
- xorg-xinit
- xorg-xauth
- mcookie
- tput
- shutdown
Cloning and Compiling
This repository uses submodules, to clone it properly please use
git clone --recurse-submodules https://github.com/cylgom/ly.git
To compile you just need to launch make in the created folder
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 make run
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 pop over the login prompt,
edit open the configuration and make sure force_update is enabled
[box_main]
force_update=1
Configuration
All the configuration takes place in /etc/ly/config.ini.
The file is commented, and includes useful defaults.
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 login field).
Tips
The numlock and capslock state is printed in the top-right corner. Use the F1 and F2 keys to respectively shutdown and reboot. Take a look at your .xsession if X doesn't start, as it can interfere (this file is launched with X to configure the display properly).
Additional Information
The name "Ly" is a tribute to the fairy from the game Rayman. Ly was tested by oxodao, who is some seriously awesome dude. I wish to thank linux-pam, X11 and systemd developers for not providing anything close to a reference or documentation.
