* Having Caps Lock work as a second Control key works, but the Caps Lock status light toggles on and off as Control is pressed, giving the impression that Caps Lock is actually on. This is set in System: Preferences: Keyboard: Layouts: Layout Options: Ctrl Key Position. Track Ubuntu [https://bugs.launchpad.net/ubuntu/+bug/173350/ Bug #173350] for the latest updates.
 
* On Screen Display of special key actions quits working. The keys include the brightness and volume adjustment keys, as well as mute. [https://bugs.launchpad.net/ubuntu/+source/hotkey-setup/+bug/198197 bug report] has been filed about this, and you can subscribe to it to follow the progress. A workaround is to boot the 2.6.22 kernel supplied with Gutsy. This is already on your system by default after an upgrade from Gutsy to Hardy. See [https://help.ubuntu.com/community/GrubHowto/ChangeDefaultOS ChangeDefaultOS] for details on how to change the "default" line in /boot/grub/menu.lst and then run ''sudo update-grub''' for the change to take effect.
 
 
 
=== Sound After Suspend ===
 
 
 
After a Suspend/Resume cycle, sound may need to be unmuted. This can automated as follows.
 
 
 
First, always be sure to enter suspend by pressing "Fn-F4". Using the Suspend option on the logout menu may not produce the same result.
 
 
 
Open "Applications: Accessories: Text Editor" and copy/paste in the following:
 
 
 
# fix sound-after-resume on the ThinkPad T23.
 
  # Make sure that "amixer" is present, which is provided by the "alsa-utils" package.
 
case "$1" in hibernate|suspend)
 
    # nothing to do
 
;;
 
thaw|resume)
 
    mixers="Master PCM CD"
 
    for mixer in $mixers ; do
 
      /usr/bin/amixer -q sset $mixer mute
 
      /usr/bin/amixer -q sset $mixer unmute
 
    done
 
;;
 
*)
 
;;
 
esac
 
exit $?
 
 
 
Save the file on your desktop, naming it as "sound". Then after opening "Applications: Accessories: Terminal",
 
copy/paste in the following commands. You will be prompted for your password.
 
 
 
sudo cp ~/Desktop/sound /etc/pm/sleep.d/sound
 
sudo chmod+x !$
 
 
 
The first command copies the file in the proper location. The second one makes sure the script marked is as "executable". Now whenever Ubuntu resumes it should automatically run this script and unmute the volume. If for some reason it doesn't work, you can still run the script manually to unmute the volume, also using the terminal:
 
 
 
sh /etc/pm/sleep.d/sound
 
 
 
=== Skype Video with Logitech QuickCam Pro 9000 ===
 
 
 
Skype video can be sent or received. Doing both at the same time results in regular crashes. When sending video, the small thumbnail video of what's being sent doesn't show up. These issues could be related to the hardware being at or below the minimum recommended system requirements for Skype and this webcam.
 
 
 
=== Using a Projector ===
 
 
 
Using Fn-F7 does not cause the video to appear to on a projector. To make video appear on a projector, install S3switch. ( In a terminal: sudo apt-get install s3switch ). Once installed, you can mirror the video to a projector using the terminal:
 
 
 
sudo s3switch both
 
 
 
To switch back to only the laptop screen
 
 
 
sudo s3switch lcd
 
 
 
== Ubuntu 7.10 Gutsy Gibbon ==
 
 
 
Things generally work fine, with the following notes
 
 
 
=== Power Management ===
 
 
 
==== Sound After Suspend ====
 
 
 
See notes for Hardy, above.
 
 
 
=== Dual Monitors ===
 
 
 
Gutsy Gibbon has a new "Screens and Graphics" preferences area. It shows a second monitor possibility. Trying a test does make both the LCD and external screen active as one big gray monitor...but only for the test. Choosing the option to accept the settings does not actually cause monitor-spanning to work, but monitor mirroring does.  
 
 
 
=== CPU Frequency Scaling ===
 
 
 
CPU Frequency Scaling seems to be working automatically. To see your current speed level, activate the CPU Frequency Scaling Monitor Applet. Right click on the toolbar and select "add to panel". You can search for "Frequency" to find it.
 
 
 
== Ubuntu 7.04 Feisty Fawn ==
 
 
 
=== Power Management ===
 
 
 
The chips in T23s have the ability to run at speeds slower than their maximum, in order to save power. To see your current speed level, activate the CPU Frequency Scaling Monitor Applet. Right click on the toolbar and select "add to panel". You can search for "Frequency" to find it.
 
 
 
You can also enable this applet to allow you manually change the speed and scaling policy. To do that, run this in a terminal: "sudo dpkg-reconfigure gnome-applets".
 
 
 
These instructions are also available [http://www.ubuntugeek.com/howto-change-cpu-frequency-scaling-in-ubuntu.html illustrated with screenshots].
 
 
 
You may also need to add a couple of lines to "/etc/modules" to allow you to be able to change the processor speed and governor. The lines are:
 
 
 
acpi-cpufreq
 
cpufreq_ondemand
 
 
 
These will now be loaded on at boot time. To activate them immediately:
 
 
 
  sudo modprobe acpi-cpufreq
 
  sudo modprobe cpufreq_ondemand
 
 
 
Some technical details are explained on the [[SpeedStep]] page.

[[[Pairing wine with cheese!]]] Drinking wine with cheese is a classic combination that most people love. That being said, it is exceedingly important for anyone having cheese and wine to be able to pair the two correctly, otherwise the flavours of the cheese can completely mask the delicate taste of the wine. These days, with such wide varieties of wine and cheese, it can be difficult for the casual wine drinker to decide which two to pair together. However, as long as you stick to a few common rules you should be able to manage. Always remember that white wines tend to favour soft cheese, with a strong flavour, and red wines generally pair better with more mild, hard cheese. Keeping these two points in mind it is important that the wine you are having does not overwhelm the flavour of the cheese . The general rule of thumb is that the stronger tasting and more pungent the cheese, the sweeter the wine accompanying it should be. Putting in an example here, many people enjoy an aged Zinfandel with Mozzarella cheese. They swear by this combination. Mozzarella is a rich and chewy cheese that perfectly complements the taste of the aged Zinfandel. There are other combinations like the Lockwood Sangiovese or the Italian Chianti that are excellent matches for Gruyere, a sweet but slightly salty hard cheese. Even Cheddar cheese can be paired with wine. One of the wines that is most often paired with cheddar is a Shiraz or Shiraz Cabernet from Australia, this combination gels especially well if the cheddar is nicely aged. A famous wine expert, Josh Wesson often said "Don't have the wine step all over the food or the food step all over the wine. Two different flavours can be synergistic, producing a third flavour experience". The same holds very true when pairing wine and cheese. If the two are not paired correctly the wine can easily overshadow the taste of the cheese and vice versa. It is important to remember, the taste of the food and wine being served should always complement each rather than compete and contrast.
