<div>Folks:</div>
<div><br>A bit more info. This echo response issue is only happening in my environment when the external monitor is plugged in, and happens on either test monitor, and using either Startech. </div>
<div> </div>
<div>For the test, I'm just typing 123123123 repeatedly into terminal. This symptom happens both on gnome and sugar terminal screens.</div>
<div> </div>
<div>It's a 'production' XO-1 with the three pad trackpad.. It is a virgin fs-update install of build 358</div>
<div> </div>
<div>However, I have now ascertained that It is not actually a 'delay' it's a full pause. Meaning, when it stops echoing it *stops*; then, only when I hit the next character, do both the previous and the current characters echo. To be clear, if I type 123, and only the 1 and 2 appear, then when I hit 1, both the 3 and the 1 then appear.</div>
<div> </div>
<div>I will try the tackpad wiggle, and also try the whole test again this time on the XO 1.5 later today. </div>
<div> </div>
<div>Unfortunately, for now, Work interferes again :-)</div>

<br></div>A similar symptom was seen in the past day on an XO-1 with single-area<br>Synaptics touchpad running an upstream kernel. Key events were delayed<br>by the interrupt stream from the touchpad. It has not been seen on the<br>
OLPC kernel yet. If it occurs with power management disabled, you can<br>exclude idle suspend as a contributing cause.<br><font color="#888888"><br>--<br>James Cameron<br><a href="http://quozl.linux.org.au/" target="_blank">http://quozl.linux.org.au/</a><br>
