Touchpad: scorrimento a due dita come sul Mac, su qualsiasi portatile Linux
[This guide is available in English on Wiz and Chips]
ATTENZIONE!! LE NUOVE ISTRUZIONI AGGIORNATE PER UBUNTU E KUBUNTU 8.10 INTREPID IBEX SONO IN FONDO A QUESTO ARTICOLO!
Ci sono cose sul Mac che, persino io devo ammettere, sono davvero ragguardevoli.
Una di queste, è lo scrolling a due dita sul touchpad dei Macbook e Macbook Pro. Il touchpad è comodissimo, se non si ha lo spazio o il piano di appoggio per un mouse, ma potrebbe essere davvero più usabile. E' possibile abilitare una zona sulla destra (a volte serigrafata addirittura sul pad stesso) per scorrere le pagine web o le interfacce del sistema operativo, ma personalmente la trovo scomodissima, perché ci finisco sempre durante i normali movimenti del puntatore.
Insomma, secondo me la soluzione Apple è ideale, ma richiede hardware appositamente progettato, hardware Apple. Oppure no?
Assillato dal dubbio, ho fatto un po' di ricerca. E i risultati sono stati assolutamente sorprendenti. Così sorprendenti da farmi domandare come abbia fatto a non averne mai sentito parlare prima, ma soprattutto a chiedermi come sia possibile che laptop di altri produttori non beneficino di questa capacità (brevetti?).
Ciò che segue vale solo per Ubuntu 8.04. Per la versione 8.10 seguire le istruzioni in fondo al post.
Su lucumr apprendo la sconvolgente verità: lo scrolling a due dita è possibile con moltissimi touchpad di marca Synaptics, che a quanto mi risulta ha praticamente il monopolio del mercato. Inoltre il driver Synaptics per Linux supporta lo scorrimento a due dita verticale ed orizzontale, al modestissimo prezzo di aggiungere due righe di configurazione a xorg.conf:
Option "VertTwoFingerScroll" "true"
Option "HorizTwoFingerScroll" "true"
Ricaricato X (ctrl+alt+backspace) scopro che il trackpad dell'Acer Aspire sul quale ho provato la modifica supporta alla perfezione lo scorrimento a due dita.
Proseguo la ricerca, su Ispirazioni Informatiche trovo che questa opzione è disponibile in Linux addirittura dal 2006, e che aggiungendo un'ulteriore riga a xorg.conf è possibile installare anche un bel pannello di configurazione grafica per queste nuove opzioni.
Ecco le istruzioni passo passo per abilitare questa funzione su Ubuntu (e sulle distribuzioni basate su GNOME, per le distribuzioni KDE basta, in genere, limitarsi a sostituire gedit con kwrite o kate).
1) fare un backup di xorg.conf:
sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.synaptics
(ho l'abitudine di rinominare i file con qualcosa che mi ricordi l'operazione che mi apprestavo a fare prima della modifica, ma qualunque nome va bene)
2) aprire xorg.conf:
sudo gedit /etc/X11/xorg.conf
3) Aggiungere le tre righe
Option "SHMConfig" "on"
Option "VertTwoFingerScroll" "true"
Option "HorizTwoFingerScroll" "true"
alla sezione InputDevice di Synaptics, che apparirà quindi all'incirca così:
Section "InputDevice"
Identifier "Synaptics Touchpad"
Driver "synaptics"
Option "SendCoreEvents" "true"
Option "Device" "/dev/psaux"
Option "Protocol" "auto-dev"
Option "HorizEdgeScroll" "0"
Option "SHMConfig" "on"
Option "VertTwoFingerScroll" "true"
Option "HorizTwoFingerScroll" "true"
EndSection
4) Installare gsynaptics dai repository. (Si posizionerà in Sistema->Preferenze)
5) Riavviare X, o l'intero PC.
Oltre allo scrolling a due dita, se si abilita il tapping, anche questo può avvenire in modalità multipla:
Tap a 1 dito: click con il tasto sinistro del mouse
Tap a 2 dita: click con la rotella del mouse, in firefox apre il link in un nuovo tab.
Tap a 3 dita: click con il tasto destro del mouse [Grazie Claudio]
Per evitare problemi, consiglio di effettuare l'operazione solo con un mouse USB di emergenza a portata di mano.
Per chi fosse scettico, o per chi non ha familiarità con lo scorrimento a due dita ho messo su YouTube un breve video dimostrativo.
>>AGGIORNAMENTO 8.10<<<
Per Ubuntu 8.10 Intrepid Ibex, Kubuntu 8.10 e probabilmente la maggior parte delle distribuzioni basate sul nuovo Xorg 7.4 la procedura è radicalmente cambiata.
A quanto pare abilitare SHMConfig è sconsigliato in un ambiente multiuser "untrusted", ovvero nel quale non conoscete o non potete fidarvi a priori degli altri utenti.
Il modo più sicuro per abilitare lo scorrimento a due dita in questo caso è utilizzare un file XML per l'Hardware Abstraction Layer con le impostazioni per questa funzione.
Il file deve contenere questo testo:
<?xml version="1.0" encoding="ISO-8859-1"?><deviceinfo version="0.2"> <device> <match key="input.x11_driver" contains="synaptics"> <merge key="input.x11_options.SHMConfig" type="string">On</merge> <merge key="input.x11_options.TapButton2" type="string">3</merge> <merge key="input.x11_options.TapButton3" type="string">2</merge> <merge key="input.x11_options.VertTwoFingerScroll" type="string">1</merge> <merge key="input.x11_options.HorizTwoFingerScroll" type="string">1</merge> </match></device></deviceinfo>
ed deve essere salvato come:
/etc/hal/fdi/policy/11-synaptics-options.fdi
Se non avete familiarità con linux seguite queste semplici istruzioni:
- Scaricate il file già pronto che ho preparato per voi, nella vostra home (esempio /home/carlo)
- Aprite il terminale, verificate di essere nella vostra home, e digitate:
sudo cp 11-synaptics-options.fdi /etc/hal/fdi/policy/
Riavviate il pc (riavviare X non basta più).
Lo scorrimento a due dita dovrebbe funzionare.
Abilitare GSynaptics e SHMConfig.
Se siete gli unici utenti sul vostro PC, o volete comunque abilitare GSynaptics (o QSynaptics per KDE) dovete creare il file:
/etc/hal/fdi/policy/shmconfig.fdi
contenente:
<?xml version="1.0" encoding="ISO-8859-1"?>
<deviceinfo version="0.2">
<device>
<match key="input.x11_driver" string="synaptics">
<merge key="input.x11_options.SHMConfig" type="string">True</merge>
</match>
</device>
</deviceinfo>
Ancora una volta ecco le istruzioni semplificate:
- Scaricate il file già pronto che ho preparato per voi, nella vostra home (esempio /home/carlo)
- Aprite il terminale, verificate di essere nella vostra home, e digitate:
sudo cp shmconfig.fdi /etc/hal/fdi/policy/
Riavviate il PC.
Cercate ed installate gsynaptics con il vostro gestore dei pacchetti.
E' tutto, verificato su Ubuntu 8.10 Intrepid Ibex

Hi this is somewhat of off topic but I was wondering if blogs use WYSIWYG
editors or if you have to manually code with HTML. I’m starting a blog
soon but have no coding experience so I wanted to get advice from someone
with experience. Any help would be greatly appreciated!

My coder is trying to convince me to move to .net from PHP.
I have always disliked the idea because of the costs.
But he’s tryiong none the less. I’ve been using Movable-type on a variety of websites for about a year and am nervous about switching to another platform.
I have heard fantastic things about blogengine.net.
Is there a way I can import all my wordpress posts into
it? Any kind of help would be greatly appreciated!

“Venture Capital Venture” is an business term that numerous entrepreneurs will latch onto with no really understanding the genuine sope of what it suggests. EXOR’s goal is to beat the MSCI World Index in Euros inn the long term by way of the increase in its Net Asset Valuhe (NAV). As of Tuesday’s close, its stake was worth just about $12 billion, creating Didi an unprofitable trade if a single accounts for the time worth of income. They’ll then nnot only add value in basic but will unlock the worth of the equity, a specific skill which a lot of owners don’t buut have, for the reason that they haven’t required to. Taking a important step forward with a small business usuually calls for some sort off investment and in general there arre two recognised economic routes. Many other monetary routes are closed off in the present climate and non financial adjustments, while potentially optimistic, will not have the very same impact. Cap table, financial liability (loans or encumbrances), so that they may realize the terms in which other people invested and what outstanding liabilities the corporation may possibly be topicc to that could impaact money flow annd income redemptions. Total Investment is the total amount of capital the VC fund has invested. The laqrger thhe fund, the bigger the standard amount of investment per corporation, with rights for follo on investment.

I think everything posted was actually very logical.
However, what about this? suppose you were to create
a killer post title? I am not saying your information is not solid.,
however what if you added a post title to possibly grab people’s
attention? I mean Touchpad: scorrimento a due dita come sul Mac, su qualsiasi portatile

You ought to glance at Yahoo’s front page and see how they create article titles to grab viewers to open the links.
You might add a related video or a picture or two to get people excited about everything’ve got to say.
In my opinion, it might make your blog a little livelier.

Then, loosen up and let the massage work its wonders.
You’re the one putting within the work. Nectar’s site says many forms of bed frames and foundations can work with its reminiscence foam mattress, including adjustable bases, box springs, divan bases,
conventional frames and platforms. Tware says the hoodie is ideal for de-stressing on the workplace and even on the go.
For the review unit, Tware equipped an Android phone with CyanogenMod installed.
The design crew stripped back a variety of old features-except within the reception area,
where they lined the again wall and ceiling with felt. Dubbeldam used “threads of communication” as the overarching theme, stringing colourful yarn between rooms and upholstering the entranceway walls in rows of
felt. Slack worked with Dubbeldam Architecture and Design to create an area that
performs up the platform’s pro-chat purpose, encourages productiveness and-most significantly-has room for their
rapidly increasing employees. The mood is saved fashionable with vibrantly coloured nooks and streamlined lighting, whereas cozy lounges and a employees photograph wall create
a homey atmosphere-all with out a single Ping-Pong desk in sight.

But what if you can get a massage while you labored? Another
issue to contemplate is where you plan on using
the massage gun. The 1080p camera has a wide 120-diploma area of view,
streams stay HD video proper to your cellphone, and even lets you take photos or file
video utilizing easy hand gestures (i.e. “paper” to start out recording, “scissors” to take an image).
Available in a range of colours, including black, white,
crimson, desert rose, and a PSG-themed machine, the gun is simple and simple to operate,
with a single energy button powering the gadget on, and permitting customers to toggle between the three
velocity settings. A really successful approach to inquire about
quantum results in gravitational settings has been the
use of quantum area concept in curved backgrounds.
It receives bog normal reward for being “dark” or
“gritty,” but the Empire Strikes Back is simply a tight,
properly-structured flick that makes nice use of its iconic character set.

Now could your hope and healing lead me shortly to a place of restoration. This collection of
Scriptures on healing will present encouragement, power, and consolation as you
focus on God’s healing power. My personal perception is that
talents should be either fun, or be of equal power throughout all the tier and
each be helpful. Each questionnaire variable was reduce to 2 teams, low (0)
and excessive (1), to produce two teams as equal
size as potential in size. For a given respondent and affective state,
the threshold is obtained by utilizing commonplace equal probability discretization cite (Witten et
al., 2016). This respondent-conscious discretization is done for the questionnaire variables,
in addition to software repository variables when they’re used
as consequence variables. Participants have been also given the choice to view the dataset in its entirety via a
web-based hyperlink to a spreadsheet. Conversely, the accelerations measured earlier than the intervention are used because the ’anomaly’, given the excessive degradation of the bridge’s construction.

However, since the main intention of this analysis is to conduct a preliminary study
on the use of an accelerometric sensor-based system to watch fetal
and maternal health in the house, the impact of maternal movements on the sensor information was also observed.
An analogous strategy was considered in this research to
guage the respiration patterns of pregnant mothers to evaluate their health.
Following the fabrication of the system, a number of preliminary assessments were conducted on the system
to establish its efficiency in different environmental circumstances in addition to how it responds to
different behaviours of pregnant mothers. Gravitational
wave parameter inference pipelines function on data containing unknown sources on distributed hardware with unreliable performance.
The subject was advised to alter into different positions and the tri-axial accelerometric information have
been noticed. Furthermore, the effect of the place of the topic
on the readings was observed by taking reading while the subject was in several positions such
as the Fowler’s place, Supine position, and lateral recumbent position.
Initially, the topic was advised to wear the belt and
to remain seated in the Fowler’s position for an prolonged time and the tri-axial accelerometric information had
been recorded (see Figure 6). It may be noticed that the subject’s
respiratory pattern will also be observed very clearly from the accelerometric
indicators.

The particular attention is also given to the effect of the hidden criticality at which the disparity between the healing lengths is most pronounced.
2006) The doping impact by oxygen is reported to be negligible within the absence of
mild.Kuroda and Flood (1961); Ogawa et al. Furthermore,
this ratio might be altered by doping in superconductors Lee2006 ,
changing the topology of the Fermi surface Cappelluti2007 , engineering the
interface of the system Peng2014 , making use of the pressure Tissen2013 ; Suderow2005 , and changing the characteristic
dimension of nanoscale superconductors via the
quantum-measurement results Blatt1963 ; Shanenko2006a ; Guan2010 ;
Chen2010 ; Shanenko2008 ; Chen2012a . POSTSUBSCRIPT and the presence of
the Friedel-like oscillations can under no circumstances distort
our outcomes. 1, the period of such oscillations
is the same for each contributing bands. POSTSUBSCRIPT
the Debye frequency assumed the same for each contributing bands.

Vitamin C is required by the brain to make neurotransmitters.
A prolonged lack of sunlight can cause a vitamin D deficiency, which can put older adults at risk of fractures and falls.
In severe cases, loss of smell can lead to depression. However, psychological trauma and loneliness can also lead to physical health problems.
It slowly gets worse over time and leads to dementia, but the right help and support can manage
the symptoms. Early symptoms of chronic traumatic encephalopathy may not be noticeable at first.
Your sense of smell often serves as a first warning signal, alerting you to the smoke
of a fire, spoiled food, or the odor of a natural gas leak
or dangerous fumes. This approachable, culturally-agnostic test will, for the first time ever, enable screening at
scale. The length of time that a person spends in solitary confinement varies greatly.
Sometimes, prisons and jails also use solitary
confinement to house people in protective custody who are not safe in other areas of the institution. Some researchers suggest that people in protective custody prefer solitary confinement
to being in the general prison population housing
because it is safer.
