Next time a freeze happens, restart the system and then run this command
to collect the log from the previous (frozen) boot:

  journalctl -b-1 > prevboot.txt

and then send us the file 'prevboot.txt'.

Title:
  Xorg freeze ( also Nvidia freeze (tested) )

Status in Ubuntu:
  Incomplete

Bug description:
  Hi, I have been using Ubuntu 14.04 LTS for 6 years without problem and
  I decided to renew my operating system to Ubuntu 18.04 LTS with fresh
  install 5 months ago.

  When I started to use ubuntu 18.04 LTS, I encountered some desktop
  freezes randomly. While it was happening, I can heart that my laptop's
  fan noise was incredibly increasing abnormally at that moment.

  So I have decided to change my driver from X.org Server to Nvidia
  (recommended). When I switch my driver from open source graphic driver
  to proprietary graphic driver, I hoped that the problem might be
  solved. But after a week, the problem occured again. After that in the
  same day the same freezes occur continuosly as much as 3 or 4 times. I
  don't know why it happens. The only thing I know is Ubuntu 14.04 LTS
  was using Unity Desktop, and Ubuntu 18.04 LTS is using GNOME Desktop
  anymore.

  I tried to alt + f2 and r command to refresh gnome desktop. Also ctrl
  + alt + f3 for instance, and typing gnome-shell --replace & disown to
  refresh gnome dektop. They sometimes works, but only if I notice early
  that the freezes coming. If I miss that moment, the screen completely
  freezes and neither cursor click nor keyboard input works

  What should I do?

  1) &
  2)

  My system info:
  =================================================
  Description:     Ubuntu 18.04.2 LTS
  Release:         18.04
  Ubuntu Software:   3.28.1
  =================================================

  
  3)

  I shouldn't have had to restart my system again, again and again due
  to desktop freezes. While it happens, session cannot be rescued. It
  damages my personal / work data on the RAM at that moment. I mean I
  encountered data loss a lot of times on the gedit or the web browser
  mostly, while writing or doing something. I was expecting this issue
  was reported someone in the internet since 5 months. Because of this,
  I didn't deal with it. But I guess so this is not common issue.
  Because, there is no patch for it. I am looking details of system
  update when it has come each time, but no patch there until this now.
