As james had presented before, 1.1 is using one hacking method to make it (MT) work. And it is driver specific to make the mtdev (kernel part) work.

I don't think so, it might ask your port in driver for following MT protocol, and also need new libmtdev for translating the protocol. @Joel, > Which touchscreen driver does the Lenovo S10-3t use in MeeGo?

For 12777, tsc2007 will only work with evdev for single touch, mtev will not support it. @rudi, > a new issue, but there is a workaround), the y coordinate of the > touchscreen is reversed (that is deliberate as far as I know and was > done for the Russelville and Northville platforms). > > > Rudi Can you please tell me the reason on "deliberate"? The panel intended to report inverted Y coordinate value up? I run into some weird issue on NV and RV with tsc2007, even though before the upper level inverted the value from lower level and seemed works well, but from log of device file, seemed the Y coordinate value is right, and anyway, now input driver can not make the coordinate value right even with "invertY" option. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Gabriel M.

Here's how I understand the state of things with touchscreen drivers, xorg, and the Cando touchscreen in the Ideapad's: MeeGo 1.1: - 2.6.35 kernel + mtdev driver patch. The mtdev driver would intercept the Cando device, instead of using the driver from the vanilla kernel. There were about 4 specific devices intercepted/handled by this kernel driver. - A specific version of xorg-driver-input-mtev that is looking for /dev/input/mtev (or something like that). MeeGo 1.1.90.x: - 2.6.37 kernel with no special patches - Xorg with newer version of xorg-driver-input-mtev and a xorg.conf.d file to map the Cando device to the Xorg mtev driver. Getting your wires crossed between the kernel mtdev patch and the Xorg mtev driver will mean no multi-touch (and sometimes no single touch). I think a non-mtdev-patched 2.6.35 kernel will probably work with the newer Xorg mtev driver (with Xorg.conf.d file). I haven't tried it myself, though. -gabriel _______________________________________________ MeeGo-dev mailing list [email protected] http://lists.meego.com/listinfo/meego-dev http://wiki.meego.com/Mailing_list_guidelines _______________________________________________ MeeGo-dev mailing list [email protected] http://lists.meego.com/listinfo/meego-dev http://wiki.meego.com/Mailing_list_guidelines
