I’ll question my on assertion, Should evdev recognize a “single point, resistive touch screen device”, as a USB Mouse or as some other device? For multi-touch we know mouse did not work. But I think it also did not work for single touch, where when it was treated as a mouse, we could swipe (“drag” like a mouse), but could not tap (“click” like a mouse).

It is being recognized as a USB device, but not as a touchscreen, so it defaults to being a mouse, which it is not. When you say “touch input is not working with this board”, what specifically is the failure mode? Does it respond to taps at all? Does it respond to “drag” at all?

I recall there is an xinput_calibrator tool that you might be able to use to calibrate it. I don't remember if that tool was included in Tizen 2.0 though. -Kevron On Thu, Sep 5, 2013 at 5:03 PM, Prabhuram Murugan <[email protected]<mailto:[email protected]>> wrote: Hi All, I am using TIZEN 2.0 ... Jeol, I gone through the changes, https://review.tizen.org/gerrit/#/c/6047/ , but it is for Weston and TIZEN 3.0 however to fix this issues in TIZEN 2.0, I am looking in to adaptation/xorg/driver/xserver-xorg-input-evdev can you advice, if this is the right point to start , Rusty, Yes, we are using a single point, resistive touch screen device. and from the mount point /dev/input/mouse1 looks it is detected as the mouse device. TIZEN 2.0 doesnt support single touch device ?

I'm not sure if you were using a touchscreen with the same issue, but we hit an issue when a vendor wired up an old style single point resistive screen on top of an egalax touchscreen controller, where weston didn't recognize the device as touch (since it didn't support the modern multipoint protocol), and treated it as a mouse, but then the device would emit TOUCH_BTN instead of a left or right mouse button. So... it actually worked, but no software is listening for this little known button value so kind of pointless. --rusty On Thu, 2013-09-05 at 14:21 +0000, Clark, Joel wrote: > This has been fixed in Tizen IVI 3.0 > https://bugs.tizen.org/jira/i#browse/TIVI-1086 > > > > You might want to look at these patches: > > https://bugs.freedesktop.org/show_bug.cgi?id=54428 > > > > https://review.tizen.org/gerrit/#/c/6047/ > > > > with the fix the touchscreen is no longer recognized as a mouse > device. > > > > Regards > > Joel > > > > > > From: [email protected]<mailto:[email protected]> > [mailto:[email protected]<mailto:[email protected]>] > On Behalf Of Prabhuram Murugan > Sent: Thursday, September 05, 2013 5:38 AM > To: IVI Tizen > Subject: egalax touch screen not detected by X > > > > Hi , > > > I am using a USB based touch screen LCD for TIZEN on NDiS 166 board. > > > But the touch input is not working with this board. > I came across many bugs raised in TIZEN bug site, but they are mostly > for touch calibration. > > > In my case the touch screen is detected by the kernel but "xinput > list" doesnt list my touch screen device at all.
