Question: I was bored recently so I decided to download and install drivers from ASUS site. My motherboard is Asus P5K. After downloading the drivers, I messed up the installation somehow (don't remember the details) and now I don't have sound at all!

I'm new to Ubuntu and I don't have a clue how driver setup works. 
Can you tell me how to bring back the old drivers or how to install this driver? And the first driver worked perfectly, but I was curious about the new driver so I messed up :(

P.S, Ubuntu 14.4

Answer: 
I think you should install the *ibus-m17n* package.

```
sudo apt-get install ibus-m17n

```

Then, next time you log in, you should see a bunch of new Sinhala options when running *ibus-setup*. Pick the one of your choice, and hopefully it makes a difference.
I recently had a really hard time making this work and finally solved my problem using `xfce4-xkb-plugin` on Lubuntu 18.04.

First install the plugin

```
sudo apt-get install xfce4-xkb-plugin

```

then right-click on the task-bar and click **add/remove panel items** , it will open a **Panel Preferences** window

Click the `+Add` button; it will open **Add plugin to panel** window
select **Keyboard Layout Handler** and click `+Add` button

Now back in the **Panel preferences** window select **Keyboard Layout Handler** and click the `Preferences` button

This will open the **Keyboard Layout Handler** preferences window, whereyou need to do the following:

Under **Advanced setxkbmap Options** uncheck *keep system layouts*

Under **Keyboard Layouts > +Add** select the language you want to add

Under **Change Layout Option** choose the keys you want to toggle between the languages
