Hi, im new to linux, and ubuntu. Ive got acer aspire 1420p convertible laptop. After installation everything works fine, only problem seems to be that touch screen doesnt work at all. When i touch the screen mouse will click applications in upper left corner.
Ive read many many many guides how to configure touchscreen, but nothing seems to be working. Touch screen is resistive multitouch MosArt (according to http://lii-enac.fr/en/projects/shareit/multitouch-devices.html it's the same one as on ASUS T91M)
I would appreciate any help how to fix this issue, but think of me as a newbie in linux world>) thanks

I too had this problem, but a wonderful post (with video) allowed me to fix the problem myself. Here is the link:

Good luck!

I think this touchscreen is not supported as multi-touch, but as a single-touch panel...

You may need to download xf86-input-evdev 2.4 or above version of the driver, compile and install it.

But prior to this you need to download the dependencies :

sudo apt-get install build-essential
sudo apt-get install autoconf
sudo apt-get install libtool
sudo apt-get install x11proto-core-dev
sudo apt-get install x11proto-xext-dev
sudo apt-get install libxi-dev
sudo apt-get install xserver-xorg-dev
sudo apt-get install xutils-dev


./autogen.sh --prefix=/usr

sudo make install

Reboot and it just work.. Hopefully... ;)

Hi! Same problem for me (klick on the Acer Aspire 1420p screen brings the mouse pointer to the upper left corner and does the click there).

However, I followed the same discussion in some other forum, and it seems that a patch about that just made it into the currently developed Linux Kernel 2.6.36-rc7
(http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=e1f092102f65e424be40c318a0fab7b b6e34194f)

So as soon as 2.6.36 comes out, which should not take too long any more, I guess, the screen should run with some package like x-server-xorg-input-evtouch or similar. I'll try it then.

However, my question is now (not really very experienced!): At what time will I get the new Kernel for my system (running 10.10 Maverick Meercat)? Will it a) come with the regular update, or only, if I b) upgrade to a later (yet to come) version of Ubuntu?

Thanks,
Noek

Now it works, using Kernel 2.6.36. As I understood from this thread
http://ubuntuforums.org/showthread.php?t=1604192&highlight=kernel
the Kernel in 10.10 will most likely never be changed to 2.6.36. Therefore, I installed the new kernel manually - I used the deb-Package, see this thread:
http://ubuntuforums.org/showthread.php?t=1603401&highlight=kernel
Works fine (including the touchscreen), but as I understand it, this kernel will not be automatically updated, since it does not originally belong to the 10.10 system. Well, I can live with that ;-)
