Menu of the indicator, shown on click. The locks can be toggled by clicking
the respective item in the menu.

-Alternative (short) appearance of the indicator.

## Installation from Ubuntu PPA
sudo add-apt-repository ppa:adrianiainlam/indicator-keyboard-led
After installation the postinst script will prompt you for preferences
configuration. These config are explained here:
-### Short label
-
-The default appearance of the indicator has long labels:
-![⚫Num ⚫Caps ⚫Scroll][sc1]
-
-On small displays it may be preferable to use short labels:
-![⚫N ⚫C ⚫S][sc3]
-
### Order
This option allows you to reorder the locks and also to hide
characters 'N', 'C' and 'S' to set this option.
For exampe, the default order is "Num Caps Scroll".
-![⚫Num ⚫Caps ⚫Scroll][sc1]
+![Num Caps Scroll][sc1]
**CNS** changes this to "Caps Num Scroll".
-![⚫Caps ⚫Num ⚫Scroll][sc4]
+![Caps Num Scroll][sc4]
**NC** hides Scroll lock from the default appearance.
-![⚫Num ⚫Caps][sc5]
-
-**C**, combined with the previous *short* option,
-would give a very compact Caps lock indicator.
-![⚫C][sc6]
+![Num Caps][sc5]

## Known bugs / Troubleshooting
+### Indicator label does not show on Xfce / XUbuntu
+
+See [#6](https://github.com/adrianiainlam/indicator-keyboard-led/issues/6).
+
### Pressing Scroll Lock does nothing
It seems to be a common problem that Scroll Lock is not usable in Ubuntu.
To solve this, do the following (assuming US keyboard):
> # backup your symbols file
- > sudo cp /usr/share/X11/xkb/symbols/us{,.distribution}
+ > sudo cp /usr/share/X11/xkb/symbols/us{,.distribution}
>
> Add the following line in the `xkb_symbols "basic" {` section. Do not worry
> if that second line is not there, it is only there for some languages and
>
> ...
> modifier_map Mod3 { Scroll_Lock }; <==<< Add this line
- >
+ >
> include "level3(ralt_switch)" <==<< before this line
> };
>
## Localization
-As motivated by Issue #1, this script has been localized to French (with
-the assistance of Wikipedia and Google Translate). Corrections to the
-translation, as well as translations to other languages, are welcome.
-Feel free to create a pull request or open an issue.
+Unfortunately, in order to work-around labels not being shown on newer
+non-Unity-based Ubuntus, I have re-designed the indicators to be based
+purely on icons instead. This means there will no longer be labels to
+localize, and I instead have hardcoded icons.
+
+The icons are SVGs so you can still manually edit them if you want.
+Look for the `<text>` tag at the end of the SVGs.
+
+The menu items shown on click are still localized.
+
+I have included a screenshot below to show the old design (version 1.1)
+which you can still install manually if you wish.
