## Requirements
|
||||||
|
- [lightdm-webkit2-greeter (aur/lightdm-webkit2-greeter )](https://github.com/Antergos/lightdm-webkit2-greeter)
|
||||||
|
|
||||||
|
## Installation
|
||||||
|
|
||||||
|
**Recommended Automatic Installation**
|
||||||
|
|
||||||
|
[Available on the AUR](https://aur.archlinux.org/packages/lightdm-webkit-theme-aether/). ArchLinux users can substitute pacaur with yaourt, packer, etc. as necessary and install with the following:
|
||||||
|
|
||||||
|
```
|
||||||
|
pacaur -S lightdm-webkit-theme-aether
|
||||||
|
```
|
||||||
|
|
||||||
|
**Manual Installation**
|
||||||
|
|
||||||
|
This assumes that you already have lightdm and lightdm-webkit2-greeter installed (but not configured).
|
||||||
|
|
||||||
|
```
|
||||||
|
# If you prefer the last stable release, download from the releases page instead: https://github.com/NoiSek/Aether/releases/latest
|
||||||
|
git clone git@github.com:NoiSek/Aether.git
|
||||||
|
sudo cp --recursive Aether /usr/share/lightdm-webkit/themes/Aether
|
||||||
|
|
||||||
|
# Set default lightdm-webkit2-greeter theme to Aether
|
||||||
|
sudo sed -i 's/^webkit_theme\s*=\s*\(.*\)/webkit_theme = lightdm-webkit-theme-aether #\1/g' /etc/lightdm/lightdm-webkit2-greeter.conf
|
||||||
|
|
||||||
|
# Set default lightdm greeter to lightdm-webkit2-greeter
|
||||||
|
sudo sed -i 's/^\(#?greeter\)-session\s*=\s*\(.*\)/greeter-session = lightdm-webkit2-greeter #\1/ #\2g' /etc/lightdm/lightdm.conf
|
||||||
|
```
|
||||||
|
|
||||||
|
### **Setting an Avatar Image**
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
Once LightDM, LightDM Webkit Greeter, and Aether are installed you will need to set an avatar image for your users. Size is irrelevant, and avatars will be displayed as a 125x125 circle (Yes, square images too). Users that don't have an avatar set will default to the [astronaut](./src/img/default-user.png).
|
||||||
|
|
||||||
|
To accomplish this, you can do either of the following:
|
||||||
|
- Create an image in your home directory named `.face`.
|
||||||
|
- Append `Icon=/path/to/your/avatar.png` to the bottom of the file at `/var/lib/AccountsService/users/<youraccountname>`
|
||||||
|
|
||||||
|
### **Using Your Own Wallpapers**
|
||||||
|
|
||||||
|
#### Method One:
|
||||||
|
Add and delete wallpapers within the `src/img/wallpapers/` directory as you see fit. By default, you will find this folder at the absolute path: `/usr/share/lightdm-webkit/themes/lightdm-webkit-theme-aether/src/img/wallpapers/`.
|
||||||
|
|
||||||
|
#### Method Two:
|
||||||
|
Edit the `background_images` value under `branding` within your lightdm-webkit config file located at `/etc/lightdm/lightdm-webkit2-greeter.conf`.
|
||||||
|
*Note: This ignores the default value of /usr/share/backgrounds, as this is always set and would prevent the default wallpapers from working. To use wallpapers from within that directory, create a subdirectory at /usr/share/backgrounds/aether (or any other folder name) and change your config value accordingly.*
|
||||||
|
|
||||||
|
### **Modifying Date and Time Format**
|
||||||
|
|
||||||
|
The formatting symbols are not necessarily what you would expect them to be! See the following:
|
||||||
|
|
||||||
|
https://github.com/samsonjs/strftime#supported-specifiers
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### My login screen hasn't changed!
|
||||||
|
|
||||||
|
Make sure you have lightdm enabled via systemctl with `systemctl is-enabled lightdm.service`. If it isn't, follow up with:
|
||||||
|
```
|
||||||
|
sudo systemctl enable lightdm.service
|
||||||
|
```
|
||||||
|
|
||||||
|
### My screen is black!
|
||||||
|
|
||||||
|
Verify that your libgl / glx drivers are properly installed. Find any potential issues with your X config by switching to another TTY with <kbd>Ctrl</kbd>+<kbd>Alt</kbd>+<kbd>F2</kbd> and trying:
|
||||||
|
```
|
||||||
|
sudo cat /var/log/Xorg.0.log | grep -i "glx"
|
||||||
|
```
|
||||||
|
|
||||||
|
Are you able to run `glxinfo` without errors?
|
||||||
|
|
||||||
|
### My system hangs at the boot screen!
|
||||||
|
|
||||||
|
Switch to another TTY with <kbd>Ctrl</kbd>+<kbd>Alt</kbd>+<kbd>F2</kbd> and check your lightdm logs by running:
|
||||||
|
```
|
||||||
|
sudo tail /var/log/lightdm/seat0-greeter.log
|
||||||
|
```
|
||||||
|
|
||||||
|
If you see something similar to:
|
||||||
|
```
|
||||||
|
*** (lightdm:709): CRITICAL **: session_get_login1_session_id: assertion 'session != NULL' failed
|
||||||
|
```
|
||||||
|
|
||||||
|
Then you should try re-installing and / or reconfiguring your graphics drivers, especially if this occurred after a kernel update.
|
||||||
|
|
||||||
|
### The lock screen isn't using my lightdm theme!
|
||||||
|
|
||||||
|
If you are using cinnamon, gnome, or any gnome derivative; Good Luck. The solution involves [light-locker (community/light-locker)](https://github.com/the-cavalry/light-locker), but conflicts with the existing lock / screensaver applications. There is no known way to resolve this.
|
||||||
|
|
||||||
|
If you are not using a gnome derivative, see below.
|
||||||
|
|
||||||
|
Solution:
|
||||||
|
|
||||||
|
```
|
||||||
|
echo "light-locker &" >> ~/.xprofile
|
||||||
|
```
|
||||||
|
|
||||||
|

|
||||||
