<p class="MsoNormal">Hello!<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We are using an embedded Platform with X11R7.7 without Window Manager.<o:p></o:p></p>
<p class="MsoNormal">The input is done over a Touchscreen with the xf86-input-tslib driver.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The behaviour until now is that a touch (click) on the touchscreen generates an input event when dpms is active.<o:p></o:p></p>
<p class="MsoNormal">This behaviour should be changed in such way that no touch(click) event should occur and screen should go on when dpms is active
<o:p></o:p></p>
<p class="MsoNormal">This has to be done because an operation could start.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So i want to implement following behaviour in the xf86-input-tslib driver.<o:p></o:p></p>

</span></span></span><![endif]>-> force dpms mode to or simply create a moving event – no „click“ should be announced<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I tried to implement this by using the DPMS Functions.<o:p></o:p></p>
<p class="MsoNormal"> if (DPMSQueryExtension(dpy, &dummy, &dummy))<o:p></o:p></p>
<p class="MsoNormal"> if (DPMSCapable(dpy)) {<o:p></o:p></p>
<p class="MsoNormal"> DPMSInfo(dpy, &state, &onoff);<o:p></o:p></p>

<p class="MsoNormal"> ErrorF(" Monitor is On");<o:p></o:p></p>
<p class="MsoNormal">….<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">My problem is that getting dpy in the driver breaks the xserver itself and i have no intention why. I also get no information why this happens until now.<o:p></o:p></p>
<p class="MsoNormal"> dpy = XOpenDisplay(dpyName);<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Does anyone know a better way how to deal with such a behaviour?<o:p></o:p></p>
<p class="MsoNormal">Is creating a socket to the XServer allowed in a driver?<o:p></o:p></p>
<p class="MsoNormal">I also checked other input drivers but didn’t find a starting point.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
