Installation was pretty easy - I booted of an Ubuntu 10.10 USB memory stick, and selected manual disk partitioning.
I kept the Windows 7 partition (/dev/sda1) unchanged, and did not touch the other two windows partitions (/dev/sda2 and /dev/sda3). I deleted the blank 'Data' partition (/dev/sda4) and created a new swap partition (/dev/sda5) and ext4 root partition (/dev/sda6).
Installation went without problem and the machine now dual boots Ubuntu and Windows 7.
Note that I did have a funny happening yesterday when the machine completely refused to boot after I had been using windows. I fixed this by booting off the USB memory stick and re-installing grub as described in a previous post - This has not happened again.
Worked out of the box.
Ubuntu did not detect the correct screen size initially - it used a normal aspect ratio rather than wide screen, so only the centre of the screen was used, and the touch screen calibration was way out - this is because it thinks it has two displays (I don't know where the second is - there is no VGA or s-video connector on the back).
This was fixed by going to the System->Preferences->Monitor menu and un-checking the "Same image in all monitors" option.
You can then drag the main screen (labelled "Laptop") away from the second (labelled "Unknown") and set the laptop resolution to 1600x900 resolution.
This makes the screen the correct size, but every now and then it flickers twice within less than a second - it seems that the screen backlight dims momentarily before coming back to full brightness. This seems to be associated with disk activity - I don't know what causes this - it does not do it in Windows - Any suggestions for fixing it would be appreciated!.
I was impressed that the touch screen worked 'out of the box' once I had fixed the monitor resolution issue.
Update 01/01/2011 - I decided to do a clean install of Ubuntu 10.10, just in case I had mangled it installing different testing packages going through bugs on launchpad. Having done the install and updating all packages using update manager, the touch screen is working perfectly - pressing the screen is the same as moving the mouse to the location and left click - Success!!!! (I hope!) - Ok, I'll give it a couple of days to make sure it doesn't beak before I say success.
