11 | 12 | _The screen layout is heavily inspired by [Sugar Candy SDDM theme](https://framagit.org/MarianArlt/sddm-sugar-candy) 13 | by Marian Arlt._ 14 | 15 | ## Background 16 | 17 | I was in need of a good login manager for the nwg-iso project. I first used SDDM with the Sugar Candy theme, and it 18 | worked pretty well. However, it brings QT dependencies, and my stuff is all GTK-based. Also, I know nothing about the QT 19 | framework, so couldn't adjust the greeter to my taste. The next choice was LightDM with [my modification](https://github.com/nwg-piotr/lightdm-nwg-greeter) 20 | of the [LightDM Elephant Greeter](https://github.com/max-moser/lightdm-elephant-greeter) by Maximilian Moser. It looked well, but LightDM would happen to hang way too 21 | often. Then I gave a try to greetd, and that was it. I only needed a nice graphical greeter based on GTK3. Since there 22 | was no such thing, I had to develop one. 23 | 24 | ## Features 25 | 26 | - Multi-monitor support with gtk-layer-shell; 27 | - multi-language support; 28 | - background and style customization with CSS; 29 | - automatic selection of the last used session and user; 30 | - avatar (user picture) support; 31 | - support for setting environment variables. 32 | 33 | ## Dependencies 34 | 35 | - python >= 3.6; 36 | - greetd; 37 | - gtk3; 38 | - gtk-layer-shell; 39 | - Hyprland or sway Wayland compositor; 40 | - gnome-themes-extra. 41 | 42 | ## Make dependencies 43 | 44 | - python-build 45 | - python-installer 46 | - python-wheel 47 | - python-setuptools 48 | 49 | ## Optional dependencies 50 | 51 | - mugshot: to set the user picture 52 | 53 | ## Installation 54 | 55 | [![Packaging status](https://repology.org/badge/vertical-allrepos/nwg-hello.svg)](https://repology.org/project/nwg-hello/versions) 56 | 57 | First, you need to [install and start greetd](https://wiki.archlinux.org/title/Greetd#Installation). 58 | 59 | The greeter can be installed as a package for your Linux distribution, or by cloning this repository and executing the 60 | `install.sh` script (make sure you installed dependencies first). 61 | 62 | Then you need to edit the `/etc/greetd/config.toml` file (or `greetd.conf` - see the tip below). 63 | 64 | ```toml 65 | [terminal] 66 | # The VT to run the greeter on. Can be "next", "current" or a number 67 | # designating the VT. 68 | vt = 1 69 | 70 | # The default session, also known as the greeter. 71 | [default_session] 72 | 73 | # `agreety` is the bundled agetty/login-lookalike. You can replace `/bin/sh` 74 | # with whatever you want started, such as `sway`. 75 | command = "agreety --cmd /bin/sh" 76 | 77 | # The user to run the command as. The privileges this user must have depends 78 | # on the greeter. A graphical greeter may for example require the user to be 79 | # in the `video` group. 80 | user = "greeter" 81 | ``` 82 | 83 | Replace the line: 84 | 85 | ```toml 86 | command = "agreety --cmd /bin/sh" 87 | ``` 88 | 89 | with 90 | 91 | ```toml 92 | command = "Hyprland -c /etc/nwg-hello/hyprland.conf" 93 | ``` 94 | 95 | if you want to use Hyprland, or this line if you prefer sway: 96 | 97 | ```toml 98 | command = "sway -c /etc/nwg-hello/sway-config" 99 | ``` 100 | 101 | NOTE: you may need `sway --unsupported-gpu` for Nvidia. Also, if you'd like to make some additional configuration 102 | (e.g., monitor layout), edit `/etc/nwg-hello/hyprland.conf` or `/etc/nwg-hello/sway-config`, respectively. 103 | 104 | __Do not change the__ `user = "greeter"` __line__, or some file-related functions won't work. 105 | 106 | ### Tip 107 | 108 | During the greetd package upgrades, the `config.toml` file may be overwritten with the default one. E.g., on Arch Linux 109 | your modified file gets renamed to `config.toml.pacsave`. This will restore the `agreety` greeter on your system. 110 | To avoid such a situation, you may use the alternative `greetd.conf` file. This has not been mentioned in docs, 111 | but greetd looks for this file first. Just copy `config.toml` to `greetd.conf` and make changes to the copy. 112 | 113 | ## Configuration 114 | 115 | Copy `/etc/nwg-hello/nwg-hello-default.json` to `/etc/nwg-hello/nwg-hello.json` and make your changes there. 116 | 117 | ```json 118 | { 119 | "session_dirs": [ 120 | "/usr/share/wayland-sessions", 121 | "/usr/share/xsessions" 122 | ], 123 | "custom_sessions": [ 124 | { 125 | "name": "Shell", 126 | "exec": "/usr/bin/bash" 127 | } 128 | ], 129 | "monitor_nums": [], 130 | "form_on_monitors": [], 131 | "delay_secs": 1, 132 | "cmd-sleep": "systemctl suspend", 133 | "cmd-reboot": "systemctl reboot", 134 | "cmd-poweroff": "systemctl poweroff", 135 | "gtk-theme": "Adwaita", 136 | "gtk-icon-theme": "", 137 | "gtk-cursor-theme": "", 138 | "prefer-dark-theme": true, 139 | "template-name": "", 140 | "time-format": "%H:%M:%S", 141 | "date-format": "%A, %d. %B", 142 | "layer": "overlay", 143 | "keyboard-mode": "exclusive", 144 | "lang": "", 145 | "avatar-show": false, 146 | "avatar-size": 100, 147 | "avatar-border-width": 1, 148 | "avatar-border-color": "#eee", 149 | "avatar-corner-radius": 15, 150 | "avatar-circle": false, 151 | "env-vars": [] 152 | } 153 | ``` 154 | 155 | - `"session_dirs"`: comma-separated paths to session directories. Modify only if you know well what you're doing. 156 | - `"custom_sessions"`: greetd can run whatever starts from the command line. This way we can add `bash`, `zsh` or something else here. The `"name"` field is the display name. The `"exec"` field is a command. 157 | - `"monitor_nums"`: leave as is to see the greeter on all monitors. Set e.g. `[0, 2]` for it to appear on the 1st and 3rd one. 158 | - `"form_on_monitors"`: which of above monitors to display the login form on (just the wallpaper on the rest). 159 | - `"delay_secs"`: some monitors take longer to turn on. In the meantime the greeter may behave oddly on other monitors. If it happens to restart/blink, increase this value. If you only have one monitor and no discrete GPU, you may probably set `0` here. 160 | - `"cmd-sleep"`, `"cmd-reboot"`, and `"cmd-poweroff"` are pre-defined for systemd-based systems. Use whatever works for you. 161 | - `"gtk-theme"`, `"gtk-icon-theme"` and `"gtk-cursor-theme"` are of little importance as long, as you use classes and IDs from the default css style sheet. 162 | - `"prefer-dark-theme"` should remain `true`, unless you need to turn it off for use with your own background and/or styling. 163 | - `"template-name"` allows use of own templates: find the built-in `/usr/lib/python3.xx/site-packages/nwg_hello-x.y.z-py3.xx.egg/nwg_hello/template.glade` file, copy to a folder somewhere in `~/`, edit and place as `/etc/nwg-hello/file-name.glade`. Do not change widget IDs. Set your `file-name.glade` as the `"template-name"` value. Leave blank to use the built-in template. 164 | - `"time-format"`: string to format clock with the strftime() function (see: https://www.man7.org/linux/man-pages/man3/strftime.3.html). 165 | - `"date-format"`: string to format date with the strftime() function (see: https://www.man7.org/linux/man-pages/man3/strftime.3.html). 166 | - `"layer"`: allows choosing gtk-layer-shell layer: 'background', 'bottom', 'top', 'overlay'; 'overlay' will be used if no value given. 167 | - `"keyboard-mode"`: allows choosing gtk-layer-shell keyboard mode: 'none', 'exclusive', 'on_demand'; 'exclusive' will be used if no value given. 168 | - `"lang"` allows you to force the use of a specific language, regardless of the `$LANG` system variable. Check if we have the translation in the [langs directory](https://github.com/nwg-piotr/nwg-hello/tree/main/nwg_hello/langs). 169 | - `"avatar-show"`: determines whether to display the user's profile picture. 170 | - `"avatar-size"`: avatar image size in pixels. 171 | - `"avatar-border-width"`: avatar border width in pixels. 172 | - `"avatar-border-color"`: a hexadecimal value of avatar border color ("#rgb" or "#rrggbb"). 173 | - `"avatar-corner-radius"`: corner radius for rectangular avatar image, 174 | - `"avatar-circle"`: draw avatar as a circle (corner radius ignored), 175 | - `"env-vars"` allows to pass an array of environment variables. Use like this: `["MY_VAR=value", "OTHER_VAR=value1"]`. 176 | 177 | ## Styling 178 | 179 | Copy `/etc/nwg-hello/nwg-hello-default.css` to `/etc/nwg-hello/nwg-hello.css` and make your changes there. 180 | 181 | ## Custom icons 182 | 183 | If you'd like to use your own icons, do not replace `/usr/share/nwg-hello/*-default.svg` files. Place your 184 | `poweroff.svg`, `reboot.svg`, `sleep.svg` and `avatar.svg` files in the same directory. Attention: the `avatar.svg` file 185 | is not your profile picture, but a generic user image! 186 | 187 | ## Own language files 188 | 189 | You can't translate labels in the .glade file, as the program replaces the values with what's defined in 190 | [language files](https://github.com/nwg-piotr/nwg-hello/tree/main/nwg_hello/langs). Since the 0.2.4 version, however, 191 | you can copy your lang file to `/etc/nwg-hello/` and make desired changes there, 192 | see https://github.com/nwg-piotr/nwg-hello/issues/19. Be careful with syntax, the JSON format is unforgiving. 193 | Test your lang file by running `nwg-hello -t -d` from terminal. 194 | 195 | ## User avatar 196 | 197 | New in version 0.4.0. Disabled in default config. Set `"avatar-show": true` to enable. 198 | 199 | The feature displays user's profile picture from `/var/lib/AccountsService/icons/$USERNAME`, stored by 200 | gnome-control-center or some other tool ([Mugshot](https://github.com/bluesabre/mugshot) does the job perfectly well). See [Configuration](#configuration) 201 | for related values. 202 | 203 | Styling: no CSS is applicable here. You can set shape- and border-related values in config. 204 | 205 | NOTE: if you use your customized `/etc/nwg-hello/nwg-hello.json` file, remember to copy all `avatar-*` key-value pairs 206 | from `/etc/nwg-hello/nwg-hello-default.json`. 207 | 208 | ## Running on Debian and labwc 209 | 210 | Submitted by [@01micko](https://github.com/01micko). 211 | 212 | ### configs 213 | 214 | #### /etc/greetd/greetd.conf 215 | 216 | ```toml 217 | [terminal] 218 | # The VT to run the greeter on. Can be "next", "current" or a number 219 | # designating the VT. 220 | vt = 7 221 | 222 | # The default session, also known as the greeter. 223 | [default_session] 224 | 225 | command = "labwc --config-dir /etc/nwg-hello/labwc-config" 226 | 227 | # The user to run the command as. The privileges this user must have depends 228 | # on the greeter. A graphical greeter may for example require the user to be 229 | # in the `video` group. 230 | user = "_greetd" 231 | ``` 232 | 233 | NOTE: The user `_greetd` is a debian thing, even though it isn't set up correctly. You have to manually add to 'video' 234 | group and `chown` all the files in `/etc/greetd`. 235 | 236 | #### /etc/nwg-hello/labwc-config/autostart 237 | 238 | ```sh 239 | # start nwg-hello - full

screenshot (using `PrtScr` key) of `nwg-hello` saved to /etc/greetd/ 245 | 246 | ```xml 247 | 248 | 249 | 250 | 251 | 252 | 253 | 254 | 255 | 256 | ``` 257 | 258 | ## Acknowledgments 259 | 260 | -
