== Current Issues ==
## List any issues you have with the current development release here

Battery life is lower than under Windoze.

Memorystick slot does not work. Apparently fixed in 2.6.25 kernel but not backported to Hardy yet. Also see http://swehrmann.blogspot.com/2008/04/memorystick-support-unter-ubuntu-hardy.html for a fix. There is also a bug in launchpad but I cannot find it!

Issues with warm docking. As a workaround suspend the machine before docking it. Resume it when docked. Bug has been fixed in upstream kernel but not backported to Hardy yet. See https://bugs.launchpad.net/ubuntu/+source/linux/+bug/194617 

External monitor hot-plugging does not work. I want to be able to place my laptop on the dock and the display to switch automatically to the external monitor. Currently I have to invoke the nvidia-settings gui press detect monitors and then configure. Would love to have this done automatically. 

Fingerprint reader does not work. This is crippled in hardware by Sony.

=== Notes ===
## Add any notes here
 * This laptop has a switch to select between speed (nvidia) and stamina (intel) mode. To enable 3-d acceleration and direct rendering under both modes do as follows (I adapted this from http://ubuntuforums.org/showthread.php?t=421350&highlight=vaio+glx): 

Step 1:

Install with graphics selector switch set to speed (nvidia) and install
nvidia-glx-new package for the NVidia restricted driver.
{{{
sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.speed
}}}

Step 2:

Set graphics switch to stamina (intel) and restart. When X server fails to start press CTRL-ALT-F1. Login and 
{{{
sudo dpkg-reconfigure xserver-xorg
}}}

After the configuration 
{{{
sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.stamina
}}}

Step 3:

{{{
sudo vim /etc/init.d/xorg_conf
}}}

Add the following contents

{{{
#!/bin/sh
#
# Set the appropriate xorg.conf and GL links for the speed/stamina video card switch
#

VIDEO=`/usr/bin/lspci |grep -c nVidia`

if [ "$VIDEO" = 1 ]; then
  cp -f /etc/X11/xorg.conf.speed /etc/X11/xorg.conf
  ln -sf /usr/lib/libGL.so.1.nvidia /usr/lib/libGL.so.1
  ln -sf /usr/lib/xorg/modules/extensions/libglx.so.nvidia /usr/lib/xorg/modules/extensions/libglx.so
else
  cp -f /etc/X11/xorg.conf.stamina /etc/X11/xorg.conf
  ln -sf /usr/lib/libGL.so.1.mesa /usr/lib/libGL.so.1
  ln -sf /usr/lib/xorg/modules/extensions/libglx.so.mesa /usr/lib/xorg/modules/extensions/libglx.so
fi
}}}
Then
{{{
sudo chmod +x /etc/init.d/xorg_conf
}}}

Step 4:
{{{
sudo ln -sf /etc/init.d/xorg_conf /etc/rc2.d/S12xorg_conf
sudo ln -sf /usr/lib/libGL.so.1 /usr/lib/libGL.so
sudo ln -sf /usr/lib/nvidia/libGL.so.1.2.xlibmesa /usr/lib/libGL.so.1.mesa
sudo ln -sf /usr/lib/libGL.so.169.12 /usr/lib/libGL.so.1.nvidia
sudo ln -sf /usr/lib/nvidia/libglx.so.xserver-xorg-core /usr/lib/xorg/modules/extensions/libglx.so.mesa
sudo ln -sf /usr/lib/xorg/modules/extensions/libglx.so.169.12 /usr/lib/xorg/modules/extensions/libglx.so.nvidia
}}}

Step 5:

Run to verify that direct rendering is enabled under both cards:
{{{
glxinfo | grep render 
glxgears
}}}

 * To enable hibernate and suspend install the restricted nvidia drivers. Then 

{{{
sudo vim /etc/X11/xorg.conf 
}}}
and add 
{{{
Option NvAGP "1" 
}}}
under "Device" (seems not always necessary). Then

{{{
sudo vim /etc/pm/config.d/unload_modules
}}}
and write into it
{{{
SUSPEND_MODULES="uvcvideo"
}}}
If you use the docking station then write instead
{{{
SUSPEND_MODULES="uvcvideo ehci_hcd uhci_hcd"
}}}
Make the file executable
{{{
sudo chmod +x /etc/pm/config.d/unload_modules
}}}

 * When using the docking station you also need to 
{{{
sudo vim /etc/modules
}}}
and add 
{{{
acpiphp
}}}
into the file. 

 * Webcam packages can be found from http://www.arakhne.org/spip.php?article50
