Enabling Acer 1825 Touchscreen on Ubuntu 10.10

[UPDATE  meanwhile you could get multitouch support, check http://www.ceh-photo.de/blog/?p=320]

So after some days of struggling with the touchscreen configuration I works very good (only singletouch).

The problem was out of the box the touchscreen is detected as a touchpad in ubuntu 10.10.  It is a problem in the xorg-evdev driver (Version) 2.32. To fix this problem you need to patch the 2.32 or build and install a newer one.

I tested both posebilities and decided, that using a newer evdev driver is the easier and better way.

If you know what you need to do it is very easy operation.

sudo apt-get install build-essential xutils-dev xserver-xorg-dev  autoconf autotools-dev libtool

# I don't know why it is not working with this modules installed -->bug?

sudo apt-get remove xserver-xorg-input-evtouch xserver-xorg-input-tslib

wget http://cgit.freedesktop.org/xorg/driver/xf86-input-evdev/snapshot/xf86-input-evdev-2.5.0.tar.gz

tar xvfz xf86-input-evdev-2.5.0.tar.gz

cd xf86-input-evdev-2.5.0/

./autogen.sh -prefix=/usr

make

sudo make install

After a reboot the touchscreen should work fine in single touch mode.

For getting a right-click use System->Preferences->Mouse->Accessibility

I tested this solution on Ubuntu Desktop and Netbook Edition. On netbook edition(unity) I have some problems of clicking the application icons on the left bar. On Ubuntu desktops everything works fine.
