elo graphics driver does not work after upgrade to natty

[Matthew Darwin]

Binary package hint: xserver-xorg-input-elographics

After upgrading to natty (from maverick), the serial input for the elographics driver does not work. However, Xorg does recognize it.... it's just that touching the screen does nothing.

[p pelikan (ppelikan)]

Can anyone help? This problem affects also newest versions of Ubuntu (11.10 and 11.04). The elographics / elotouch driver is in repository but it doesn't work at all. How can I fix it? Maybe there is other driver, which can handle the touchscreens connected to COM port.

Looks like the situation is even worse now in Precise - i just filed #1058109
