Comment 32 for bug 1453812

I don't know if it can be useful or not. I replaced the nouveau video driver with proprietary nvidia driver (340.76, tested). No more freezing experienced with LO writer BUT when I was using Evince to read some pdf (while LO writer was running) I experienced a GUI freeze by clicking on the top bar of Evince going to select "always on top" option. Fortunately I was able to enter in a tty session; after killing evince I was able to come back to the GUI and take control over it (and save the LO writer document).
