<div dir="ltr">Hi<div><br></div><div>I'm having a hard time with the following problem concerning an eGalaxTouch device.</div><div>At first sight, everything seems to be working fine using the evdev driver with libmtdev. I have no problem with pinch/zoom etc. But after a short time Xserver emits button-press events immediately after button-release, even when you do a simple single tap.</div>
<div>So tapping once on the screen results in "button-press" - "button-release" - "button-press". This makes any application behave strangely or it even gets stuck.</div><div><br></div><div>I've written a simple test application printing the "ButtonPress" and "ButtonRelease" events coming from the X server (looping over XNextEvent) and the problem is evident. I can get X to behave correctly again by clicking a normal mouse. But using the touchscreen will almost immediately get it in the wrong state again.</div>
<div><br></div><div>mtdev-test from libmtdev shows no problems at all and evtest also not, so I'm pretty sure it's a problem in X or evdev_drv (I didn't find a way to hook onto evdev yet). Both evtest and mtdev-test nicely emit button-press and button-release without extra events.<br>
<br>Perhaps a similar issue was reported last year, but I don't know if there was any follow-up: <a href="http://lists.x.org/archives/xorg-devel/2012-October/034047.html">http://lists.x.org/archives/xorg-devel/2012-October/034047.html</a></div>
<div><br></div><div>Can someone share some insight, please?</div><div><br></div><div><br></div></div>
