Ubuntu 13.04 Installation – Fix acpid: exiting Error

Starting 13.04, applications will have to integrate into the indicators and can no longer have their own status icons in systray in Unity. (This may change in future.)

The Unity systray whitelist has been removed, so you can no longer whitelist applications to allow them to use the notification area in Ubuntu 13.04 Raring Ringtail. However, Java and Wine applications have been hard-coded as the only software still able to use the notification area so this change only affects some old applications that don't come with AppIndicator support. And since Qt applications systray icons are automatically converted to appindicators thanks to sni-qt, this change shouldn't affect too many applications.

First off, in Linux every hard drive has its own letter going from 'sda' to 'sdb' to 'sdc' and so on. But for every partition, you will get a 'sda1', 'sda2', 'sda3', and so on for each partition on a hard drive.

There are two ways to fix this, the automatic way and the manual way. In the end, they do exactly the same thing. If you know what you are doing and want to spare some time, go with the manual way

The Automatic way.

1. Move all files from D:/ to C:/ as a backup
2. remove the D:/ partition and expand C:/ over where D:/ was before.
3. Boot the live USB again and select "Install Ubuntu alongside windows" and set how big you want

The Manual way.

1. Move all files from D:/ to C:/ as a backup

2. Boot the live USB

   Now, in Linux, these partitions have different names!

3. select 'Something else'
4. Delete the partition after windows (which was called D:/ by windows) and expand it to the end of the hard drive except for 2-8gb of free space that we are going to make swap later on.
5. Format that partition as Ext4 and set the mount point as /
6. Make the last partition out of the remaining 2-8gb of space, and format it as SWAP.

7. In the dropdown menu on the bottom that's called something like 'bootloader location', set it to the correct hard drive (This will be the same as the windows or ubuntu or swap partition name but without a number, for example,/dev/sda, /dev/sdb or /dev/sdc)

8. Simply continue installing ubuntu!

I hope this helps, and just place a comment if you encounter problems!
