[Linux] Laptop Troubles

[Crimson Behelit]

Hey there,

Just yesterday I purchased a brand-new Centrino-based notebook. As soon as I brought the new unit home, I fired up Gentoo's installer. This morning I woke up to a vanilla gnomebook :)

I'm having some troubles configuring the pointing device on the notebook. Here is an image:

Unfortunately, I don't know the name of this type of pointing device, nor do I know the name of the 'arrows' that would serve as scrolling aids (much like a mouse-wheel). Since I don't know the names of these devices off-hand, I haven't had much success searching google for an answer to my question(s).

My question(s) is:

a) What are these components called? (I'm referring to the 'pad' device & 'scroll buttons')

b) How would I go about configuring the pointing device to include scrolling support?

It is important I mention that the 'pad' already functions in it's most basic operating mode (meaning I can manipulate the pointer on-screen by moving my finger along the 'pad'). The 'scroll buttons do not work.

Cheers

Well, if the pad is working, then it may just be a matter of defining scroll zones (I don't use a touchpad, so I don't know). But the scroll areas aren't a different device or anything, so you don't need a separate module (I wouldn't think) to deal with them.

A google came up with this link on FC3/4, and some of the information in the xorg.conf may apply to set up a scroll zone on your pad.

^ I set my touchpad up the same way. Apparently theres no way to get horizontal scrolling working, but vertical works just fine.

The first thing that I did was disable the tapping, because it is way too sensitive on my laptop.

Here's the conf from the Ubuntu LiveCD. All I had to do was set HorizScrollDelta to 1 to get horizontal scroll working.

Thanks for the input guys... still no luck with touchpad scrolling :unsure:

I have another issue that sould probably be dealt with first. My notebook has two ethernet devices: one wired (Realtek) and one wireless (IPW2200). They each work seperate of eachother just fine.

Is there a daemon (or another process) that will auto-switch between wireless and wired ports upon inserting a wired cable (or conversly detecting a wireless connection)? The way I have things set up is that one nic must be disabled for the other to work... while it is easy enough to manually shut one device and start the other, I was hoping that both[/b] can be configured and enabled at all times using the wireless ethernet device if there is no wired connection.

I bet that sounds confusing... the reason I am interested in this is I'd like to be able to roam wirelessly in any given WAP at all times, however if I need a full 100MBPS connection, I can plug a wire into the wired port and use it instead of the wireless.

Here is my /etc/conf.d/net

config_eth0=( "192.168.1.113 netmask 255.255.255.0" )

routes_eth0=( "default via 192.168.1.1" )

config_eth1=( "192.168.1.114 netmask 255.255.255.0" )

routes_eth1=( "default gw 192.168.1.1" )

modules=( "wpa_supplicant" )

wpa_supplicant_eth1="-Dipw"

wpa_timeout_eth1=60
