Linux on Sony Vaio Z-series, Dell Latitude E4200 E4300, ThinkPad X301, Toshiba Portege R500 R600, Samsung X360, Acer Timeline 3810T

There are now 7 different Launchpad groups for Linux Ultrathin laptops.
Each team is a group for people who own or develop for a given laptop model, so that we can have more useful Linux usage information, and send better bug reports upstream. This gives more visibility to the group when having to ask for patches or support.

The current groups are:
Bragging rights ranking: (1) 2254 points, (2) 250 points, (3) 81 points, (4) 44 points, (5) 32 points, (6) 23 points, (7) 23 points, (8) 18 points, (9) 15 points, (10) 13 points.
Highest Bragging rights: 5996 points

Sony Vaio Z series and Linux: How to switch intel/nvidia card

For laptops like the Sony Vaio Z series, there is currently Linux support for cold switch of the graphics card:

Load Eva's sony-laptop module with speed_stamina=3.
In the file called /etc/modprobe.d/sony-laptop.conf add the following line:

options sony-laptop speed_stamina=3


Then boot with this kernel parameter (use the quotes):

acpi_osi="!Windows 2006"


Just put it in the kernel command line of your boot manager.

Now you can switch between stamina and speed without booting to Windows, but your laptop have to be completely powered off, not rebooted.

Nvidia driver overwrites libglx.so and libGL.so.1 with symbolic links like mentioned above. So before installing nvidia driver, backup the current libglx.so und libGL.so.1 to libglx.so.INTEL/libGL.so.INTEL. If you have already installed nvidia, you can get the original files from "xserver-xorg-core" package, respectively "libgl1-mesa-glx".

For loading the correct xorg.conf, this little script needs to run before starting xserver:



#!/bin/sh

lspci | grep "00:02.1"

if [ $? -eq 0 ]; then
   cp /etc/X11/xorg.INTEL /etc/X11/xorg.conf
   ln -sf /usr/lib/libGL.so.INTEL /usr/lib/libGL.so.1
   ln -sf /usr/lib/xorg/modules/extensions/libglx.so.INTEL /usr/lib/xorg/modules/extensions/libglx.so
else
   cp /etc/X11/xorg.NVIDIA /etc/X11/xorg.conf
   ln -sf /usr/lib/libGL.so.185.18.08 /usr/lib/libGL.so.1
   ln -sf /usr/lib/xorg/modules/extensions/libglx.so.185.18.08 /usr/lib/xorg/modules/extensions/libglx.so
fi

More developments are expected in the future, once the nvidia bytecode interpreter is in full shape in the nouveau project.

Update on current status of Hybrid graphics support for Sony Vaio Z series and Linux

Having a fully-working nvidia hybrid graphics laptop with Linux has always proven difficult, but more features are being implemented as more information about the inner workings of nvidia hardware are investigated.

Matthew Garrett (mjg59) and Stuart Bennett (malc0) managed to run nouveau'S BIOS parser (http://mjg59.livejournal.com/91888.html) in the kernel together with nv but it is not integrated with nouveau yet, causes
lockups with nouveau and only works for certain older cards (like
nv44).

The nvidia BIOS contains bytecode scripts that are able to initialise the chip, but we don't have a bytecode interpreter that can parse them fully. There's a partial one in the nouveau project.

MSI X340 gets mixed review at wired.com

MSI X340 | Wired.com Product Reviews

Let's cut to the chase and hit you with the sell: The MSI X340 is a MacBook Air at half the price. Interested? R ead on.



Netbook shop MSI has deconstructed Apple's pioneering three-pound
wedge and built what is, put simply, an amazingly credible knockoff.
Like the Air, the X340 transcends many of the limitations of the
netbook world, though it still has a few of its own flaws to contend
with.



For starters, the X340 (aka the X Slim) is considerably better
muscled than your typical netbook, featuring a glossy 13.4-inch (1366 x
768 pixels) screen, 320-GB hard drive and 2 GB of RAM. Like Apple's
ultralight, it's incredibly thin — about 0.8 inches at its thickest
—and it actually weighs slightly less than the Air, just 2.9 pounds.
The only real departure from the Air's specs is the new 1.4-GHz
ultra-low-voltage SU3500 chip, which is based on Intel's Core 2 Solo
CPU. The Air offers a full Core 2 Duo, by contrast. Still, the SU3500
ekes a lot of performance out of its mere 5.5 watts of power: The
X340's performance wasn't much worse than the MacBook Air's in our
testing.



Foes of Apple's non-replaceable battery design decision will
appreciate that the super-slim cell in the X340 can indeed be removed.
You also get two USB ports instead of just one, an SD card slot, and
both VGA and HDMI output ports. As with the Air, there's no optical
drive, but more than anything else, that's the price that must be paid
to achieve such weight and thinness.



Before you start salivating over the prospects of a half-price Air,
note that Apple's laptop does trump the X340 in a few significant ways.
The Air includes Nvidia graphics, while the X340 is stuck with Intel's
integrated chipset. The screens are night and day: The Air is renowned
for having one of the brightest LCDs available, while the X340 is
merely average in this department. And then there's battery life. The
Air will run for more than three hours before dying, while the X340
sputters out before it hits two. For a machine with no optical drive,
that's a little disappointing. Of course, the X340 doesn't run MacOS,
either.



Still, it's hard not to be enchanted with the X340, and that $900
price tag looks like a typo when it's put side by side with a $1,800
Air. Put simply: This laptop is a true head-turner, and if squeezing
every last ounce out of your bankroll is your game, this is — by a wide
margin — the best value going in the world of ultralights.



WIRED Gorgeous design; slap an Apple sticker over
the MSI logo and no one will ever know. Performance bests most
netbooks, though it's hardly top-notch. Surprisingly good graphics and
responsiveness. Includes the usual goodies: 1.3-MP webcam, Bluetooth,
802.11n.



TIRED Flaky touchpad. Disappointing battery life.

Acer Aspire Timeline 3810T

For Linux information on the Acer Timeline 3810T, click here: http://launchpad.net/~acertimeline

First Look: Acer Aspire Timeline 3810t - Information World Review

Acer's Aspire Timeline 3810t is part of a new range of laptops from the vendor aimed at offering a longer battery life without pushing up the weight too much. The system has also been designed with style in mind, with a brushed aluminium casing and a minimalist appearance.

Available from 15th May, the Aspire 3810t is the smallest of the Timeline models, equipped with a 13.3in wide-screen display and weighing in at about 1.6kg.

This makes it comparable with Lenovo's thin-and-light ThinkPad X300 and X301 models but, while Lenovo manages to squeezes in a DVD-R/W, no optical drive is fitted to Acer's model.

However, it should be noted that, while a ThinkPad X301 costs well over £1,000, this model costs £700 or less, depending on the processor fitted.

Our first impressions of the Aspire 3810t is that it feels like a well built system that will stand up to life on the road. We were impressed by the display, a high-brightness Acer CineCrystal with a resolution of 1366 x 768 pixels, and also with the keyboard, which has large well-spaced keys that make for comfortable typing.

One slight niggle is that the laptop lid cannot be pushed right back, which means that the screen points towards your chest if you are using the system on your lap. The touchpad also has a single bar instead of separate buttons, and is flush with the case and has very little movement when pressed.

Our review sample of the Aspire 3810t was based on a 1.4GHz ultra-low voltage Core 2 Duo SU9400 processor with 2GB DDR3 memory (upgradable to 4GB) and 320GB hard drive. The operating system supplied is Windows Vista Home Premium.

For connectivity, the laptop is equipped with 802.11a/b/g/n Wi-Fi and Bluetooth, plus a gigabit Ethernet port. It also has a HDMI digital video output in addition to a standard VGA connector, plus three USB ports, audio jack sockets and a slot for SD Card, Memory Stick and XD Flash storage cards.

Acer quotes a battery life of up to eight hours for the Aspire 3810t, which we intend to test in a later full review. This is a bold claim for such a relatively light system, especially when the battery that came with our unit was no larger than standard and rated at 5600mAh.

However, Acer claims that features such as Intel's Display Power Savings Technology and its own Smart Power software cut power consumption to make this possible.

The latter optimises the system for longer battery life. When you unplug the mains adapter, it turns off the Aero Glass visual effects and closes the Windows Sidebar, for example.

Overall, the Aspire Timeline 3810t looks good for its £609 + VAT price on first impressions, but check back here for a more in-depth review later.


Acer Aspire Timeline 3810T, 4810T and 5810T laptops | What Laptop

Acer Aspire 4810TWhile lots of its rivals are introducing more and more budget models, Acer has bucked the trend and released a range of upmarket laptops, called the Aspire Timeline series.

The range is currently made up of three machines, the Aspire Timeline 3810T, 4810T and the 5810T. Offering screen sizes of 13.3, 14 and 15.6-inches, respectively, these laptops look ideal for the commuter, with the smallest machine weighing in at a claimed 1.6kg.

Weights are kept down by a thin design and the use of quality materials, such as brushed aluminium, also helping to create a premium feel. In addition to the light weights, Acer has concentrated on battery life, with the company claiming all-day usability from a single charge.

With a choice Ultra Low Voltage (ULV) Intel Core 2 Duo processors in place, in order to offer better mobility, don’t expect scintillating performance, although multi-tasking should be possible due to the inclusion of speedy DDR3 memory and an optional solid state drive (SSD).

Prices are yet to be revealed, but the Timeline series goes on sale in the UK within the next two months. Visit www.acer.co.uk for more information.
