Help me fix this touch-madness anyone? (Touchpad/touchscrn)

Hi there,
I have got here an interesting machine. Inhon Carbonbook. I got it as a present for my 30s birthday from a friend.
I still havent made up my mind as do i hate it or love it. It has some advantages, its quite powerfull and lightweit. Its actually a real ultrabook so to speak.
But it has some issues. There are some design flaws. First it can sometimes overheat quite a bit.
But the main thing is. It has a touch sceeen. Back when i first saw laptops with touchscreens i tought nah not really interesting. But then i thought, uhm, why not, you dont have to use it. And if you have it yo actually can use it.
But no. Now have one. And it actually only disturbs me from time to time pissing me off. Mostly when you push it unexpectedly.
And another thing is. Its touchpad works terrible.
You see there are no buttons. And everytime when i try to push a left 'button' (side of the touchpad)with the left hand to hold a window and move it moving my finger from the right hand over the touchpad. It starts jumping like crazy all over the screen not understanding my input. Doing pushes and drags all sort of stuff all over the screen.
Ok i got an external mouse. Obviousely. But its hard to say this behaviour is joyful. :D

So i wonder does anyone know anything i can install setup to let this touchpad work in a normal way?
Or any linux distro that would actually make it work, having better support for this sort of stuff?
I tried already OpenSuse and Fedora, and now am running Mageia Gnome. (Thought Gnome 3 would fit the touchscreen somewhat better then the KDE).
And i would really love to just turn off the touchscreen functionality comletely. This way i think i could come to really love this rare beast.
Or is it maybe so that this sort of hardware is so rare that this is its problem that it has the possibility of maybe not be able to even work decentely on Linux?

Thanks in advance,
BH

In GNOME control center there are no settings for the touchpad? gnome-control-center -> hardware -> mouse and touchpad ?
EDIT: Nahh, seems only really basic settings. KDE offers more there with kcm_touchpad
But you should probably post what touchpad that is. Please post the output of
Code: Select all
lspcidrake -v
synclient -l
xinput list

(you may need to install xinput for the latter command.)

yea that also seemed to me as the thing that we were searching for

i have read some of this and other links,

and it looks to me that i have to blacklist i2c-hid to disable the touchscreen and that it also might solve the working of the touchpad by loading it as a real touchpad, which would solve all both problems i posted here about and make it perfect for me. I just havent figured out yet how to bllcklist on Mageia.

Was trying to do this:
Code: Select all
echo 'blacklist i2c-hid' > /etc/modprobe.d/no-touchscreen.conf

and this:
Code: Select all
cp /etc/modprobe.d/blacklist-mga.conf /home/ndo/Documents/blacklist-mga.conf && echo '#blacklisting touchscreen' >> /etc/modprobe.d/blacklist-mga.conf && echo 'blacklist i2c-hid' >> /etc/modprobe.d/blacklist-mga.conf

and rebooting, but it doesnt get blacklisted yet

edit: typo

edit2:
also tried this line:
Code: Select all
cp /etc/modprobe.d/blacklist-compat.conf /home/ndo/Documents/blacklist-compat.conf && echo '#blacklisting touchscreen' >> /etc/modprobe.d/blacklist-compat.conf && echo 'blacklist i2c-hid' >> /etc/modprobe.d/blacklist-compat.conf

but still doesnt work

Just like you did it. But you have to understand that this only applies to automatic load at system boot.
If anything requests this module to be loaded, or if you dod a modprobe manually, it will still be loaded. You could try to move away/rename the kernel module in question.

EDIT: FWIW, the suggestion from http://forums.linuxmint.com/viewtopic.p ... 44#p907744 is also only effective to prevent loading a module in the initrd/at boot time.
Check https://access.redhat.com/documentation ... sting.html for more details.

Also it's rdblacklist=modulename not rd.blacklist=modulename
