I've played around over the past two days ( well, what else is Christmas Day and Boxing Day for ) and have taken a slightly different path to the same destination.
Instead of using Synaptic, Envy or apt get install, I chose to download the proprietary ATI driver from here.
This downloads a 80 MB file ati-driver-installer-8-12-x86.x86_64.run. It's necessary to make this file executable ( chmod +x ati-driver-installer-8-12-x86.x86_64.run ) and then execute it with root privileges ( sudo ./ati-driver-installer-8-12-x86.x86_64.run ).
The installer walks you through a series of simple screens, and, following a reboot, you're good to go.
Will continue to play ...

When I used the ATI Catalyst Control Centre ( amdcccle ) to set my display resolution, I noticed that the changes were not being saved through a reboot. As an example, I could set the resolution to 1600x1200 to get the best out of my Thinkpad's HUUUUUGE screen, when I rebooted, the resolution would be back at 1024x768, which is a bit annoying.
As usual, Google had the answer, Google is my friend. I searched for "amdcccle saving" and found this article - the answer is to run gnome-display-properties and click Apply to save the current configuration ( this applet can be as a command ( ALT + F2 ) or via System -> Preferences -> Screen Resolution.
Strange but true

However, I think I've cracked it - I went back in time in my blog and found this post from September, where I'd fickered with /etc/default/acpi-support and changed: -
If it helps, I'm using the fglrx 8.54.3 driver which I got via apt-get install fglrx* - as far as I know, this is not a proprietary driver BUT I MAY BE WRONG.
If it helps, this is how I can see what driver I'm using: -
lsmod | grep -i fglrx

Having got fglrx installed and having hacked acpi-support, I can now suspend and resume.
I can also switch to a single or dual display ( using my Sharp Aquos 26" LCD display ) using the ATI Catalyst Control Centre ( command is amdccle ) to switch between screens.
I'll test a real projector later today ....

Only one little niggle - USB support didn't work; I was getting
Failed to access the USB subsystem.
Could not load the Host USB Proxy Service (VERR_FILE_NOT_FOUND). The service might be not installed on the host computer.
when I attempted to edit the virtual machine's configuration.
However, as usual, Google had the answer ( and is my friend ).
As per this post, there are some post-installation incantations that you need to run.
Once done, we're good to go.
Next, I'm going to install WebSphere Portal or, perhaps, Lotus Connections onto the VM and see how it performs ....
I'd previously set this up in an earlier release ( I even found a developerWorks forum post from myself back in 2006 ), but had forgotten precisely how to do it.
I confused myself by reading the formal documentation so ended up hacking around and stop/starting the portal several times.
In the end, the trick was to: -
a) Amend C:\IBM\WebSphere\wp_profile\PortalServer\config\SiteAnalyzerLogService.properties and add/change: -
( there are a number of other isLogging parameters to choose from )
b) Push the updated properties into the portal configuration, using the command: -
from the directory C:\IBM\WebSphere\wp_profile\ConfigEngine.
c) Restart the portal
Once this has been done, you can see/change the properties by logging into the WebSphere Application Server administration console ( https://localhost:10041/ibm/console ) and then navigating to Resource > Resource environment providers > WP SiteAnalyzerLogService > Custom properties as per the screenshot.
Having restarted the portal, and logged in, I now see data such as: -

being logged to C:\IBM\WebSphere\wp_profile\logs\WebSphere_Portal\sa.log.
I can now use my log analyser tool to see what's going on within my portal.
I'm actually using AWStats on my Ubuntu host whilst the portal is running within a VMware image.
I'll use the AWStats documentation as well as this excellent article from Stefan Liesche on developerWorks.

Have just downloaded the most excellent Lotusphere 2009 sessions
database from Genii Software's website here: -
I used this last year ( well, this year 'cos we're still in 2008 ) and
found it be of great use in planning my way around.
This year, I notice that they also have iPhone and Blackberry versions;
will try the iPhone version as well.
Instead, I saw: -
[12/12/08 17:05:40:640 GMT] 00000041 SystemOut O Inside-Out, Default.jsp: Exception raised: java.lang.NullPointerException
When I looked at the fix list for WebSphere Portal 6.10.1 at: -
I can see: -
PK74444 WebAppIntegrator throws a NullPointerException when urlFindInTheme tag is used in a Portal 6.1 theme
so I immediately went looking for the fix - sadly, it's not available as a standalone fix, but only as part of the fixpack.
Given that I wanted to get 6.10.1 installed, I started the download - thanks to the power of broadband, this 400 MB file didn't take too long.
However, whilst I was waiting, I was fickering around with my portal, trying to reproduce another issue with SSL/HTTPS. As part of my fickering, I toggled the theme for the top-level Content Root -> Home page from Portal Default Theme to PortalWeb2 and back again.
This seemed to "kick" WAI into life, and it's now working perfectly.
I can only assume that the theme toggle forced one of the theme JSPs to be recompiled or, perhaps, magic occurred.
In either case, WAI is now working WITHOUT needing to apply any fixes or fixpacks.

IBM and Business Partners Introduce a Linux-Based, Virtual Desktop
This solution runs open standards-based email, word processing, spreadsheets, unified communication, social networking and other software to any laptop, browser, or mobile device from a virtual desktop login on a Linux-based server configuration.
A virtual desktop looks like a traditional desktop but is not limited to a single physical computer. Instead, many virtual Linux desktops are hosted on a server. The combined solution includes:

It was a most excellent question to which I didn't have an immediate answer. However, thanks to my social network ( actually knowing the man who knew and finding him on Sametime ), I was able to help solve it.
It turned out to be a location preference/setting, which can be set as follows: -
a) Choose File -> Preferences -> Locations
b) Edit the location that you usually use
c) Navigate to the Mail tab
d) Set "Transfer Outgoing Mail If X messages pending" to 1
e) Click OK to save the location change
f) Click OK to save the preference change
Hope this helps someone as it helped Mike and I
( with thanks to Chris for his most timely and excellent help )
