Dell Latitude XT

Today I installed Windows 7 (build 7600) on my Dell Latitude XT.

Visual Studio

First I installed Visual Studio 2010 Professional from MSDN. When I went to activate it I was said

The key cannot be used to extend this product.

But it was still activated… What are the odds?

Multitouch

Multitouch manipulation actually works!

Get drivers here – N-trig DuoSense® Multi-Touch Package for Windows 7 for the Dell Latitude XT

Update: 2011/08/12: The device can no longer be found by the drivers?

External monitors

Additionally I was able to connect two external monitors to my Dell Latitude XT.

Does anyone know how I can keep the two external monitors DVi and VGA while still also using the touchscreen LCD display?

Issues

My issues currently:

1. Touch input issues random clicks sometimes
2. Touch input locks up sometimes
3. CPU Clock Speed may be locked to 800 mHz instead of maximum 1200 mHZ. Heat/Fan problem?
4. Biometric Coprocessor is not configurable

Here is a list of issues reported elsewhere:

AC power adapter wattage and type cannot be determined

Dude, this seems to be broken!

My laptop was hibernated and I was out for a few hours. After I returned I simply powered on my Dell Latitude XT. Now the BIOS tells me it wont charge my battery. This is not good at all. After some physical inspection of the AC power adapter and the cord I did not detect any defects. I decided to give it another shot – and no warning this time. I think I will need to replace my 6 months old AC power adapter.

The AC power adapter type cannot be determined.  Your system will operate slower and the battery will not charge. Please connect a Dell 45W AC adapter or higher for best system operation.

n-trig: Failure to open Device

Bummer, this new Dell Latitude XT is showing some attitude. It looks like n-trig hardware is plugged into the hardware via USB interface and once you boot inside dock while other USB devices are connected the touchscreen wont load.

Read more about it here and here.

Update: Read more on Wikipedia.

Update: What the hell? Its 2009.07.17 now and I still get the same error! This just isn’t funny anymore.

Working on a raycaster

First things first. I got a brand new dell latitude xt tablet. They talk about multitouch, but believe me, its not there yet. Atleast not in a sense of a real multi-touch. Maybe with the next update from dell…

In the meanwhile I have been working on a wolf look a like and learning about raycasting. Someday there will be a release where one can play multiplayer flash wolf on a touchscreen:)
