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."

In the forums -- Dell Studio XPS 13 and Linux

[ubuntu] Installation of the nvidia drivers - Page 2 - Ubuntu Forums
Finally I managed to make it work, thanks to all the help i got.
So to resume everything that one must to make the nvidia drivers work for Linux 8.10 on a Studio XPS 13:

1.Exit the GUI, type: "Ctrl+Alt+F1"
( to return press Ctrl+Alt+F7)

2. $ sudo killall gdm
(to stop the GUI)

3. $ sudo apt-get install nvidia-180 modaliases
(this will download the driver from internet, and since I'm not sure how to connect with wifi, use ethernet)

4. $ sudo apt-get install nvidia-glx-180
(this will install the driver, just enter y when it is asked)

5. When the install is finished:
$ sudo nvidia-xconfig
(there will be an error, doesn't matter)
Type in the same command again
(this time it will work)

6. $ sudo reboot
(restarts the computer)

7.At this point it will give the error, 'no screens'
enter your username and password then:

$ sudo nano /etc/X11/xorg.conf
(this will edit the xserver configuration page)

8.Go down to "Section Device"
And add a the very end the line:
BusID "PCI:03:00:0"
(remember this is for the studio xps 13)

9.Quit the editor with:
Ctrl+X
then:
Y
then:


10. reboot the computer once more and tadaaa, it works

I spent such a time to make this work, I was very happy when it finally worked, thanks alot for the help from everybody.

P.S If this doesn't work just reboot the computer choose the restricted partition, and just do do "Repair X"

In the News -- The Inquirer

Nvidia pumps hybrid graphics to laptop makers - The Inquirer
SONY, FUJITSU Siemens and Benq have announced notebooks using hybrid graphics that allow users to “dynamically switch” between Intel’s Centrino 2 integrated graphics and a discrete Nvidia Geforce GPU.

The switch can be made without the need to reboot, giving the user the choice of whether to burn up the battery in 3D mode, or idly noodle about in 2D on the Interweb.

According to Nvidia, all its Geforce 9M Series GPUs support the hybrid graphics feature, but notebooks have to be specifically designed.

Four firms have joined the bandwagon, after guinea pig Acer tested the water. Sony’s new Vaio Z series, Fujitsu Siemens’ Amilo XI 3650 and Benq Joybook’s S42’s all have the feature.

“Performance when you need it, battery life when you don’t. And no rebooting!” said Nvidia’s chief spinner, Derek Perez, when we asked him about it.

Yes, but does it actually work?

“It’s clear that it is indeed working and in customers hands today,” Perez said

What is Hybrid SLI?

Scalable Link Interface - Wikipedia, the free encyclopedia
In response to the PowerXpress technology from AMD, a configuration of similar concept named "Hybrid SLI" was announced on January 7, 2008. The setup consists of an IGP as well as a GPU on MXM module. The IGP would assist the GPU to boost performance when the laptop is plugged to a power socket while the MXM module would be shut down when the laptop was unplugged from power socket to lower overall graphics power consumption.[9][10]

Hybrid SLI is also available on desktop Motherboards and PC's with PCI-E discrete video cards. nVidia claims that twice the performance can be achieved with a Hybrid SLI capable IGP motherboard and a GeForce 8400 GS video card.

On November 5, 2008 in Microsoft’s Guidelines for Graphics in Windows 7 document, Microsoft stated that Windows 7 will not offer native support for hybrid graphics systems. Microsoft added the reason for the decision saying that hybrid graphics systems ‘can be unstable and provide a poor user experience,’ and that it would ‘strongly discourage system manufacturers from shipping such systems.’ Microsoft also added that ‘such systems require a reboot to switch between GPUs.’

On desktop systems, the motherboard chipsets nForce 720a, 730a, 750a SLI and 780a SLI and the motherboard GPUs GeForce 8100, 8200, 8300 and 9300 support Hybrid SLI (GeForce Boost and HybridPower). The GPUs GeForce 8400 GS and 8500 GT support GeForce Boost, the GPUs 9800 GT, 9800 GTX, 9800 GTX+ 9800 GX2, GTX 260 and GTX 280 support HybridPower.


What is ATI Hybrid Graphics?

ATI Hybrid Graphics - Wikipedia, the free encyclopedia
PowerXpress

Available on mainstream mobile IGP chipsets (the AMD M780G chipset), the PowerXpress technology allows seamless switch from integrated graphics (IGP) to discrete graphics on notebooks when the notebook is connected to the AC power supply for better 3D rendering capabilities, and vice versa when disconnected from power supply to increase battery life. The process does not require a system reboot as in past and some current notebook implementations.

PowerXpress (Mobile)
Mode Plugged to AC power? On-board IGP discrete AXIOM/MXM
GPU module(s)
Default PowerPlay power settings
AC Mode Yes Off On "Maximum performance"
DC Mode No On Off "Maximum battery life"

Hybrids with the Ability to turn off the 3d chip:

AMD/ATI calls it PowerXpress and Nvidia HybridPower. It uses 2 graphics cards, one energy efficient with little 3d power and the other for gaming (fast and uses more/a lot of power), the user can choose which chip to use.
This is not a new concept. Sony has build in 2 graphics chips into some of their laptops for years. In the past a reboot was required to switch between the chips. With the new generation it is possible to change between chips on the fly, the screen will flicker but no need to reboot. At least in Windows Vista (XP, Linux not supported) the user can switch freely between the chips or set up a profile to do so automatically (eg when on battery use low power chip and when plugged in use the more powerful chip).

The graphic card hybrid not only works with two Nvidia or AMD cards but the low power Intel graphics solutions (mostly shard memory) can also be combined with 3d chips from AMD or Nvidia. This solution is ideal for users who want maximum battery life and be able to play current games. The most likely combination is Intel shard memory graphics card for battery life and some low to mid level 3d chip. This will not give great 3d performance but enable you to play some games.

Limitations are the drivers. Special drivers are needed depending on which graphic chips are combined in the hybrid. This will most likely make you depended on the Notebook manufactures driver support. It is uncertain if 3rd party drivers (such as laptopvideo2go) will be usable.

The following notebooks have Nvidia hybrid graphics (as seen on the link below):

- Sony VAIO Z (Nvidia GeForce 9300M GS & Intel GMA 4500MHD)
- Fujitsu Siemens Amilo XI 3650 (Nvidia GeForce 9600M GT & Intel GMA 4500MHD)
- BenQ Joybook S42 (Nvidia GeForce 9600M GT & Intel GMA 4500MHD)

- MSI EX630

On the NVidia side, we reported this issue in the nvnews forum:

On the AMD/ATI side, we got words from Alex Deucher that he will liaise with AMD for docs in time:

On the Sony Vaio Z series, right now both cards are visible under Linux, but there is no way to hot-switching-off (if that is a word...) the Nvidia card. There are currently ~100 users of Sony Vaio Z series using Linux that would like this feature to be implemented. See:
