Random Keyboard or Pointer Freezes

I am experiencing a strange issue with Arch on my ThinkPad E15. Out of nowhere, I get sudden keyboard or pointer freezes. The solution is relatively easy (nevertheless annoying) when the pointer freezes: I just launch the terminal and disable and then re-enable the pointer via xinput - it seems to work. However, it gets really problematic when the keyboard freezes, as I cannot use the terminal then. Furthermore, it is accompanied by a freeze in other system functions. For instance, I cannot press any tray icon in the panel. When I press anything there, it just gets stuck highlighted but no option shows up. This is why I cannot even reboot the laptop the way I am supposed to, and I have to resort to forcefully pressing the power key to shut it down - the issue is gone when the system is back up. Do you have any idea about why this might be happening?

For clarification, when I say "freeze" I mean that it does not recognise my input.

Also, I don't know whether it has something to do with my DE, but I am using xfce4.

Re: Random Keyboard or Pointer Freezes

You can probably still switch to another VT w/ the keyboard and the cause is gonna be something grabbing the input device(s)

xdotool key "XF86LogGrabInfo"

will print the grabs into the xorg log (if you're losing the keyboard, don't forget to "export DISPLAY=:0" from the tty login), the active one is the one that occupies your device(s) and you can trace the offending client from that info.
