Using Fedora 23 with xorg-x11-xserver 1.18.2, KDE plasma 5.19 on a Lenovo Thinkpad 450s. The mouse/keyboard/display freezes for periods of 20-40 seconds but if you wait long enough it starts until the next freeze. I get messages: =========================== [ 1120.069] (II) SYN_DROPPED event from "TPPS/2 IBM TrackPoint" - some input events have been lost. [ 11[ 1120.069] (II) SYN_DROPPED event from "TPPS/2 IBM TrackPoint" - some input events have been lost.

Here is my analysis: xorg-x11-server-1.18.1-3, EGL interface, libinput-1.2.1-3 NO PROBLEMS xorg-x11-server-1.18.1-3, glx interface, libinput-1.2.1-3 OCCASIONAL FREEZE xorg-x11-server-1.18.2-1, either EGL or glx interface, FREQUENT FREEZE</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
