If the folder is compressed, extract the contents.
Open up terminal, change to the directory of the theme, and run:
plasmapkg -t theme -install ./

If you have a multi-touch enabled touchpad for your laptop and are using ubuntu, it may not automatically be recognized and enabled. Here are some directions on how to do that. These directions were compiled from two sources, credited below.
Setting up Synaptics driver
Type in terminal
gksudo gedit /etc/hal/fdi/policy/11-x11-synaptics.fdi
Create and save file with this content:
<?xml version="1.0" encoding="ISO-8859-1"?>
<deviceinfo version="0.2">
<device>
<match key="info.capabilities" contains="input.touchpad">
<merge key="input.x11_driver" type="string">synaptics</merge>
<merge key="input.x11_options.SHMConfig" type="string">On</merge>
<merge key="input.x11_options.EmulateTwoFingerMinZ" type="string">40</merge>
<merge key="input.x11_options.VertTwoFingerScroll" type="string">1</merge>
<merge key="input.x11_options.HorizTwoFingerScroll" type="string">1</merge>
<merge key="input.x11_options.TapButton1" type="string">1</merge>
<merge key="input.x11_options.TapButton2" type="string">3</merge> <!--two finger tap -> middle clieck(3) -->
<merge key="input.x11_options.TapButton3" type="string">2</merge> <!--three finger tap -> right click(2). almost impossible to click -->
</match>
</device>

This allows us to use synclient utility to watch touchpad real-time data in console window.
Now restart X
sudo /etc/init.d/gdm restart
Test with command:
synclient -m 100
And you should see data like this scrolling in the terminal:

f column tells the number of fingers. w is the touched area width. z is the pressure.
If you put two fingers on touchpad and you see value f=2 then your hardware has multi-touch aware touchpad.

If you get a “Can’t access shared memory” error when you try to run the synclient command above, continue:
Create the file /etc/hal/fdi/policy/shmconfig.fdi
With the contents:
<?xml version=”1.0″ encoding=”ISO-8859-1″?>
<deviceinfo version=”0.2″>
<device>
<match key=”input.x11_driver” string=”synaptics”>
<merge key=”input.x11_options.SHMConfig” type=”string”>True</merge>
</match>
</device>
</deviceinfo>
Enabled shared memory in /etc/fstab by adding the following:
tmpfs /dev/shm tmpfs defaults 0 0

Some power settings were changed in Ubuntu / Kubuntu 9.10 that makes the speaker amp turn off when not in use–it then turns on before playing a sound, creating a (rather annoying) ‘tick’ sound. To fix this:
Edit the file: /etc/modprobe.d/alsa-base.conf
Look for the following line of code towards the bottom:
options snd-hda-intel power_save=10 power_save_controller=N
Change that line to:
options snd-hda-intel power_save=0 power_save_controller=N
…and restart! Your problem should be solved.
I have experienced a load of problems with GRUB 2 (betas that are included in Ubuntu 9.10–why did they include a beta, anyway?) so I sought a method to downgrade, or revert to GRUB legacy (ver 0.97). Below are detailed instructions, all found from the following post. Credit to posters.
http://ubuntuforums.org/showthread.php?t=1330347
Reverting to GRUB Legacy
If a user chooses to return to GRUB legacy (0.97), these steps will remove GRUB 2 and install GRUB.
The command line produces a cleaner uninstall and reinstallation. While adding and removing the packages can be accomplished with Synaptic, certain steps must be accomplished in a terminal.
- Open a terminal: Applications, Accessories, Terminal.
- Make backup copies of the main GRUB 2 folders & files. (Optional)
sudo cp /etc/default/grub /etc/default/grub.oldsudo cp -R /etc/grub.d /etc/grub.d.oldsudo cp -R /boot/grub /boot/grub.old- Remove GRUB 2
sudo apt-get purge grub2 grub-pcThe system will be unbootable until another bootloader is installed.
- Once the packages are removed, many files will still remain in ‘/boot/grub’
- Install GRUB 0.97
sudo apt-get install grub- With grub installed, the user must still create the menu.lst and stage1/stage2 files by running the following two commands.
sudo update-grub
- Generates menu.lst
- Tab to “Yes” when prompted.
sudo grub-install /dev/sdX
- Choose the correct device (sda, sdb, etc), normally the one on which Ubuntu is installed.
- Creates the stage1 & stage2 files in /boot/grub and writes to the MBR.
Run this command to keep it from upgrading automatically:
echo "grub hold" | sudo dpkg --set-selectionsReboot
I recently purchased a Lenovo IdeaPad Y450 Laptop, but the screen brightness was not being adjusted when I used the proper key combination (FN+UP/DOWN). The key combination did show the brightness bar, but did not adjust the actual brightness on the (LED) LCD. To fix this, edit /etc/default/grub:
Change:
GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash”
to
GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash nomodeset acpi_backlight=vendor”
Then run
sudo update-grub
And restart!
