Life’s an ocean with too much commotion

Here a short description on how to manage dualhead display with the NV43 GeForce Go 6600 on Ubuntu systems.

The binary drivers (listed below) available in the ubuntu repositories will not work by default for multihead displays:

• nvidia-glx-envy
• nvidia-glx-legacy
• nvidia-glx-new

Instead, the source for the nvidia-new driver needs to be downloaded and compiled. This is how you do that:
$ sudo apt-get install module-assistant nvidia-new-kernel-source
$ sudo m-a prepare nvidia-new-kernel-source
$ sudo m-a build nvidia-new-kernel-source
$ sudo m-a install nvidia-new-kernel-source

Shut down your currently running Xorg daemon:
$ sudo /etc/init.d/gdm stop # or xdm, kdm if you're running another display manager

Force the newly compiled driver to be loaded when gdm starts, by inserting the following line in your /etc/init.d/gdm init script:
( modprobe i2c-dev ; modprobe i2c-core ; insmod /lib/modules/`uname -r`/nvidia/nvidia.ko )

Make sure you’re X configuration file is configured for multihead display. You will need support for Twinview with Xinerama support.
$ sudo apt-get install libxinerama-dev libxinerama1 x11proto-xinerama-dev

Here’s my X11 configuration file (I left out the keyboard and mouse settings):

he Groupwise Client version 6.x that is available for linux is consuming too much memory. The Groupwise Client version 7.0.1 is also available but that user-friendly for installing on a distribution other than SuSE (Novell).

Follow this guide to install the groupwise client version 7.0.1 on a Ubuntu Hardy distribution. Note that this procedure may also be valid for other (debian-package supported) distributions, but it has only been tested on Ubuntu Hardy.

• Download the groupwise client 7.0.1
  wget -P /tmp http://nsn.uvsc.edu/GWClient/gw701clnxm.tgz

• Untar the contents. The tarball contains two RPM packages.
  tar -zxpf gw701clnxm.tgz -C /tmp

• Convert the Groupwise Client RPM package to a debian package with alien.
  sudo alien -d /tmp/image/2006.06.13/client/linux/novell-groupwise-gwclient-7.0.1-20060613.i386.rpm

• Install the newly created debian package
  sudo dpkg -i /tmp/image/2006.06.13/client/linux/novell-groupwise-gwclient-7.0.1-20060613.i386.deb

• This will install some files into /opt/novell/groupwise/client

• Now we have to update the java runtime environment for this Groupwise Client. On my system this only worked with the Java 6 JRE from Sun.
  rm -rf /opt/novell/groupwise/client/jre
sudo ln -s /usr/lib/jvm/java-6-sun/jre /opt/novell/groupwise/client/jre

• Place the desktop icon on your desktop
  cp /opt/novell/groupwise/client/gwclient.desktop ~/Desktop/
