In the news -- Dell XPS M1730 and Linux hybrid graphics

Dell XPS M1730 with 8800M GTX SLI reviewed -- that sucker is fast
As is usually the case when you slap the latest and greatest silicon in a laptop, it's going to best whatever came before. What's surprising here is how thoroughly the Dell XPS M1730 with a Core 2 Extreme X9000 processor and dual GeForce 8800M GTX cards in SLI trounces the last generation of tech. The folks at ExtremeTech pitted the laptop against a hapless m9750 from Alienware, sporting the last generation of tech, and it handily bested it in every competition. CPU tests were heavily in the M1730's favor, and GPU tests even more so. The only holdup is that new X9000 processor, and according to Dell a release is "imminent" -- and if you're shelling out $4480 for a laptop, it might as well be what ExtremeTech calls "the fastest notebook yet."

DSDT is an acronym for Differentiated System Description Table. This table contains the Differentiated Definition Block, which supplies the information and configuration information about the base system. It is always inserted into the ACPI Namespace by the OS at boot time.

If you've got a laptop with a IGP and a hybrid Nvidia or ATi card, and you have tried to use Linux on it, you may have noticed that there are issues with the hybrid graphics setup. To help improve the Linux hybrid graphics support for this laptop, please attach your DSDT information to this Launchpad bug report specifying your laptop model:

To compile your DSDT information, install if you haven't already the acpidump and iasl tools:
sudo apt-get install acpidump iasl           # on Debian-based systems

Then run the following commands:

sudo acpidump > acpidump.txt
sudo acpixtract acpidump.txt
iasl -d

This will create a DSDT.dsl file that you can attach to the bug report. This information will allow the developers to fully implement the hybrid graphics features for Linux.
