Like already described on https://help.ubuntu.com/community/GigabyteT1005, this touchscreen does not work with the actual Linux Kernel but there´s already a patch mentioned in the link that should solve the problem.
Could you please post (or send me) output of dmidecode? Apparently we need another entry in 8042's 'noloop' table...

I don't know much about how the Linux kernel works. Jut wanted to mention that i8042.noloop=1 is already added to the grub config and this does only enable the trackpad which does not work out of the box, too.
Some more research: Some time ago the touchscreen behaved like a relative touchpad on a fresh install and it was possible to use a patched version of the evdev driver to get the touchscreen working with single touch by compiling the patched evdev source and changing xorg.conf. But with the recent kernel versions (even since before the hid patch was merged) the touchscreen stopped working at all, and neither the old evdev workaround, nor installing the patched hid kernel modules worked anymore. It did also not behave like a touchpad on a fresh install anymore. If I remember correctly, on Ubuntu 10.10 and Fedora 15 stock installs the touchscreen worked. Fedora 16 and recent updates on fedora 15 made the touchscreen not to work anymore. So something has changed that deactivated the touchscreen?
That is interesting: By accident I have found that you have to turn on the webcam in BIOS to make the touchscreen work.

I actually have a slightly different data: Product Name: T1005 Version: GSBF05 Maybe you have the T1005P version, while I have the T1005M version: http://www.gigabyte.com/products/comparison/list.aspx?ck=5&pids=3706,3570 We should then add both of these, as well as support for Gigabyte T1125N: https://bugs.launchpad.net/linux/+bug/737482/comments/9
Created attachment 76551 [details] Patch to add T100% to noloop tables Please try this patch. Thanks!
Tested it now, and it works fine with my T1005. Please also send them to the stable backports.
Was this patch sent upstream? Feel free to add me as "Tested-by:".
