Multitouch scroll on Ubuntu 10.04

The 10.04 upgrade broke the old solution for multitouch scroll. I found a working solution on the Ubuntu forums: http://ubuntuforums.org/showpost.php?p=9115953&postcount=18 Just save the script as a .sh file, chmod +x it, and add it to startup programs.

Microphone or Audio Line In

Anyone managed to get these working?
Following the instructions linked to by dan above, I did:
cd Downloads

 wget ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.22.1.tar.bz2
 bunzip2 alsa-driver-1.0.22.1.tar.bz2 
 tar xf alsa-driver-1.0.22.1.tar 
 cd alsa-driver-1.0.22.1
 ./configure --with-cards=hda-intel --prefix=/usr
 make
 sudo apt-get install patch
 make
 sudo make install

Mike now sort of works in Sound Recorder, but the noise level is very high: whine like fan noise plus some crackling. John Ringland February 03, 2010, at 11:20 AM

also you can supposedly:

Suspend/Resume

Anyone managed to get this working?

Conserve Battery by Forcing Lower CPU Voltage

sudo -s
cat /etc/init.d/ondemand | sed 's/\([ \"]\)ondemand\(.\)/\1powersave\2/' > /etc/init.d/ondemand
/etc/init.d/ondemand restart
exit

Does this result in a noticeable performance hit? Does this result in the laptop running (noticeably) cooler? or longer battery life?

Automatically Log In On Boot

1. System->Administration->Login Screen->Unlock->Log In as <pick your name> Automatically
2. Make sure the checkbox underneath is unchecked
3. Click close
4. Go to Applications->Accessories->Passwords and Encryption Keys
5. Right-click on Login and select Change Password
6. Type in your password for old password and leave the new passwords blank
7. Hit Use Unsafe Storage

• This turns off the prompt to unlock the keyring on startup
• Since these are single-user machines, the risk of someone finding your password is low

Get Multitouch Scroll to work on your touchpad

1. Enable two-finger scroll by going to System->Preferences->Mouse->Touchpad->Two-finger Scrolling
2. Open up a terminal (Applications->Accessories->Terminal) and type in the command "gksudo gedit /etc/hal/fdi/policy/11-x11-synaptics.fdi"
3. Paste in the following:
   
   

   <?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">10</merge>
           <merge key="input.x11_options.EmulateTwoFingerMinW" type="string">8</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">2</merge>
           <merge key="input.x11_options.TapButton3" type="string">3</merge>
       </match>
     </device>
   </deviceinfo>

   
   
4. Save the file and close gedit
5. Reboot the computer

Note, by default two-finger tap should be middle click, but Ubuntu 9.10 has a bug where it is now right click. This should be fixed in future versions (see https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/432814 and https://bugzilla.gnome.org/show_bug.cgi?id=598820 : a patch exists, so if you're feeling adventurous you could recompile gnome-settings-daemon yourself to get the functionality). A temporary workaround which seems to stop working after a while of computer use is to execute the command "synclient TapButton2=2 TapButton3=3".

Alternatively, install gpointing-device-settings, (a GUI to configure touchpad and such), and run it. I like circular scrolling myself (iPod style).

Wireless button problem?

Has anyone had a problem switching their wireless back on?

3. Click "Edit Connections"
4. Go to the wireless tab
5. Click "Add"
6. Name your connection whatever you please
7. Make sure the tick mark box "connect automatically" is checked
8. Fill in SSID box "UB_Secure"
9. Go to the wireless security tab
10. Choose the "WPA2 Enterprise" option
11. Type in your UBIT username and password
12. Press "Apply".

Welcome to the internets!

Right click on it, then click "Properties", then adjust the orientation panel

To get a bunch of extra fonts

Download fonts.tar to your home directory, unpack it using
tar xf fonts.tar
in a terminal. (Creates a folder called fonts.) Then to make these available in OpenOffice, find and run
/usr/lib/openoffice/program/spadmin .
