In my ubuntu 14.04 sometimes some windows start to freeze when I try to close them the system starts to become unresponsive. It is also impossible to kill these windows.
In the syslog i found :


[72241.260112] INFO: task fsnotify_mark:200 blocked formore than 120 seconds.

But i really don't know what i can check, or verify if is a problem related of some kernel update or hardware problems....

Let's see the hardware. Please copy and paste
sudo lshw -sanitize > lshw.txt to the command line, run it and post lshw.txt in CODE tags.

i took a look to that workstation and i logged in using both Desktop Environment Unity and Awesome WM. i start to think that the problems are the Nvidia Drivers installed on that workstation but i would like to sure.
Sometimes some window freeze (and also the system freeze with unity ) but i'm not able to find anything in the syslog in order to correlate these malfunctions with the video card, or maybe i don't know where to look....

we try to change videocard....but nothing has changed..on a Workstation it happens when I close a window. Once this problem occurs, I can no longer close any window....

THis is the log, but my linux knolwdge is to "read" what it say:
