Millenium Technology Prize, Linux is in every place, Android, amazing social media coverage…
Those and other are just feel normal to me.. But for someone not being into Linux – this is A-M-A-Z-I-N-G!
Watch and learn…
The Fujitsu LIFEBOOK UH572 Ultrabook is provided with a Synaptics ClickPad device…
The whole touchpad is a button. So you can press down and have a click. I have strong fingers (playing the classical guitar) but it requires some effort to get the touchpad click and take action. Dragging is worse. While pressing down that surface it requires exercise and skill to drag the pointer to the desired position. Instead, doing a double tap and dragging is always easier.
On Linux I tested recent Ubuntu and Fedora releases and with the first installation the touchpad was not operational. Please see my other post about how to workaround that.
The workaround provided only enables 2-finger vertical and horizontal scrolls where it can be setup through “Mouse and Touchpad” program.
Meanwhile, the website for the Synaptics ClickPad claims that there is support for more:
SGS-L is provided free of charge to Synaptics OEM/ODM partners when ordered with Synaptics TouchPad and ClickPad products. To find out more about Synaptics Gesture Suite for Linux, please contact your Synaptics sales representative.
This document is prepared using Ubuntu 12.10 on UH572.
To get more out of the ClickPad we should use the “synaptiks” utility:
$ sudo apt-get install kde-config-touchpad"
Then start “synaptiks” via a terminal window or from the application menu.
synaptiks is a general tool which provides also the awesome feature of disabling the touchpad when mouse is available and typing on the keyboard.
Going into the Touchpad configuration, the latest synaptiks can only detect 3 fingers.
So the fancy 4 finger gestures are not available yet with synaptiks. Also it does not detect the “right” button, but there is a way better solution to that shortcoming.
This solves a major problem with touchpads as although it is wide, there are limits. Using a mouse, you can always pick it up and continue movement, but touchpads does not have a way to handle that. This feature provides a workaround for that problem.
We have option to use two finger scrolling or edge scrolling. Circular scrolling is possible too.
When we come to configuring the options for tapping behaviour, a lot of fancy stuff awaits us:
Since the MultiTouch device is capable of identifying locations in addition to relative movement, we can do right clicks by tapping. And with LIFEBOOK UH572, it is quite useful as it may be slightly difficult to identify the right button, especially in dark.
With Linux one of the mouse gestures I cannot live with is the middle button paste. In Linux after you select a text region, you can directly paste it using the middle button without a Copy/Paste key combination or menu selection. That makes the operation much faster. For this touchpad I use three finger tap for that middle mouse button press.
It looks like with synaptiks we can get a fairly good support for the Synaptics ClickPad device. I am looking forward to four-finger support.
Imagine you need to access your laptop and one of your hands can be full. You may be holding a mobile phone (well better use an earphone), a drink, carrying something, or worse, you may be disabled…
One important aspect of portable computers are the way their lid could be open.
It is also important that you do not want the lid got open in your bag or while carrying.
There are various lid latch implementations available in the market:
Slider on Lid
Dell Latitude D630
Dell Latitude E6420
Slider on Base:
Lenovo ThinkPad T430
This method always requires two hands to be free
Button on Lid
Button on lid was attempted in the past but not being implemented anymore. Since the lids are getting thinner, there is not much space for pushbutton mechanism. It is not really reliable too.
Button on Base
Dell Latitude E6400
Dell Latitude E6410
This technique requires the use of both of the hands most of the time.
This was attempted in the past but not being implemented anymore. Although it was the safest way to keep the lid closed, it required two hands and some extra skill
An example is Medion, another one is Fujitsu LIFEBOOK:
This method is the most comfortable for the users but still has potential issues.
Another factor for easy lid opening is the weight difference between the lid and the base. This is not significant alone as the tightness of the lid joint should be adjusted accordingly.
The easiness of the lid opening is also important for physically challenged users having problems with hands, arms. I had a fairly good idea about that when I broke my right hand more than a year ago. Having a lightweight and ergonomic device is much more crucial in those cases. There, Ultrabooks present the best option there as they are lighter.
I have done tests to open the lid of a Dell Latitude E6410 and a Medion laptop computer using only one hand. I have got interesting results.
Later, I did the same test over and over again with Fujitsu LIFEBOOK UH572:
It is just amazing that I never had those problems of not being able to lift up, the base also coming up or the device sliding on the table…
P.S. Thanks to Eren from work for triggering the idea of this blog post.
Music is an indispensable part of my life. While working on the tasks for the LIFEBOOK4LIFE project, I decided to go ahead and test the Fujitsu LIFEBOOK UH572 for music playback performance based on the music I like to listen.
To see the audio features of the device, you can see its datasheet
About audio we have the following:
There is direct reference to the sound processing features but not direct detailed references to the speakers itself. As Hi-Fi aficionados say, it is the loudspeakers, not the player or the amplifier. So the questions is:
How do the speakers perform with different genres of music?
To perform the tests I decided to use recordings from youtube.com so the same test could be repeated in different hardware too.
All the tests are done with 70% volume set to avoid any distortion or problems caused bu potentially a high volume level recording.
I should note that the comments below might be too subjective as I have a different ear sensitivity. I am too sensitive to high pitch sounds.
The pieces were first listened on an Dell Latitude E6410 to ensure that they are useful choices. The selection below represents the music I listen to these days…
Ana Vidovic playing J.S. Bach’s Suite BWV 1006a, Prelude I
It sounds ok. A bit crisp with slightly low basses but it is clear enough.
Eine Kleine Nachtmusik by W.A. Mozart
This sounds too metallic, and therefore it is annoying. This piece of music is expected to be absolutely soft (expecially compared to the ones below)
Gustav Mahler (my favourite composer) – Symphony No:8 – Veni, Creator Spiritus performed by Bayerischen Rundfunks Symphony Orchestra conducted by Mariss Jansons
Music starts at 2:15. The entrance loud and big and the speakers distort the sound right away. It is not a pleasant experience.
Gyorgy Ligeti’s Piano Etude 2: Cordes a Vide performed by Idil Biret.
Although the sound is not deep enough especially to present the low bass sounds (like the ones at the end), it is an acceptable performance.
Until this point it looks like the speakers perform better with solo instruments.
Queen – Another one Bites the Dust
The entrance is clear and the accompaniment can be recognized after a while, just the bass guitar at the beginning is almost inaudible. It gets better as the piece develops.
Metallica – Nothing Else Matters
Nice and clear opening. The actual recording is a bit too loud.
It is hard to hear the bass guitar. Drums are very clear – maybe sounds too clear or too high for this recording. The guitar solo sounds almost perfectly, maybe because it is already have a distortion pattern and pushing the limits of the speakers does not make much difference. Despite the balance problem the listening experience is acceptable.
Sepultura – Desperate Cry
Generally I get the right impression that I get from this piece. Still I think I am loosing some details while listening to this, gives a bit uneasy feeling.
The UltrabookTM provides a high quality stereo line out / headphone 3.5mm socket.
The best is to use high quality headphones. After the whole test, I gave this UltrabookTM a chance with my 7 year old audio-technica(R) model ATH-PRO30 headphones. It changes the experience completely and I could easily see the performance of the Realtek ALC269Q-VB6 and DTS(R).
Also I could not identify any background electronic interference (where I have it with the Dell Latitude E6410 – very annoying) which shows that the audio circuits are properly shielded from magnetic interference. I like it very much.
Although stereo speakers are available, the stereo feeling is not deep enough – that is due to distance beween the speakers and they are positioned next to each other instead of making them separate.
For the best of music on Fujitsu LIFEBOOK UH572, use an high-end headphone or external speakers.
