Screen on my Dell Inspiron Duo is not working with Ubuntu 11.10, though it worked when I initially installed it (~one week ago).

Another note: the touchscreen works with Windows 7 (dual boot).

I've been searchin for a solution as well.. what happened is the kernel got updated (version 3.* now) which breaks the drivers. The new touchscreen drivers can be downloaded that were made specifically for 3.* kernels but its a different configuration then before.. for example I've gotten the touchscreen working again but I can't configure the touch points. If I touch the top of the screen it clicks the bottom and vice versa.. I think a custom kernel has to be compiled and the drivers need to be configured properly.. (bangs head on desk).. I hope a solution is found soon.. untill then I contin –  user38082 Dec 15 '11 at 21:22

Got the same problem like you. Touchscreen was not working anymore on my Inspiron duo after update to kernel 3.xI. I found the solution here:

Edit /etc/default/grub:

sudo nano /etc/default/grub

Set:

GRUB_CMDLINE_LINUX_DEFAULT="usbhid.quirks=0x0eef:0x725e:0x40"

Run:

sudo update-grub

And reboot your system. Your touchscreen will now work again.
