Need help in interpreting log files

[marco07]

Folks:

I have no clue as how to interpret the following segments of my
xorg.0.log and syslog files. I copied these right after freezing of the touchpad
pointer (mouse) on my Lenovo Thinkpad t540p. I had to get back into system
using Ctrl+Alt+F1 and Ctrl+Alt+F7. Then imidiately copied the following
segments from the log files. I chose these log files from their time stamps
which matched the time freezing occured. The freezing of touchpad pointer
happens randomly every now and then as I had previously described somewhere else
in this Forum. I am on Kubuntu 14.10-64 bits.
Any help is appreciated.
Thank you!

Thanks for the link!
It had interesting information. Unfortunately could not see any hint for resolving the issue in my case.
I was already aware of the option of switching to the buitt-in Intel graphic card may be a solution. However, I prefer the nvidia card and hoping that the future updates and or newer kernels may evantually resolve this random occurence of issue.
