a few days ago I upgraded my machine (Lenovo ThinkPad T510) from Ubuntu 16.04 to Ubuntu Bionic Beaver, and since then my machine freezes somehow randomly when I use LibreOffice or when I look at pictures using Image Viewer. I would like to point out that these aren't big files or pictures, it freezes with pictures less than 1MB. When it freezes, I can move the mouse, but nothing else, and sometimes I can reboot using REISUB but sometimes not even that. I already performed a memtest86+ and it passed 1 full test with no errors found. Other than that, I don't know what else to do to file a bug for this. How are you supposed to file this type of bugs (random freezes) in Ubuntu? I'd like to point out that I never had these freezes in Ubuntu 16.04 using this same machine. Thanks in advance for your help.

Update #1: I tried executing "tail -n 99 /var/log/Xorg*.log" (with and without sudo), and I get this: "tail: cannot open '/var/log/Xorg*.log' for reading: No such file or directory". Do I need to enable something to get these logs?

Update #2: NOTE:Update removed as I've reached the max amount of characters for the Body of the question.

Update #3: @heynnema here's the result of the commands you suggested:

free -h :

              total        used        free      shared  buff/cache   available
Mem:           7.6G        2.2G        123M        205M        5.3G        4.9G
Swap:          979M         64M        915M

sysctl vm.swappiness :

vm.swappiness = 60

grep -i swap /etc/fstab :

/dev/mapper/ubuntu--vg-swap_1 none            swap    sw              0       0

Update #4: @Raffa, here are the results:

Update #5: @Raffa, I executed the commands you suggested in order to install xserver-xorg-input-all, and rebooted the machine, after which I tested using Image Viewer and LibreOffice Calc, and it froze again, so I rebooted using REISUB. At this point I started to see high CPU usage, but RAM usage remained under 2.5G. First it was slow to transition from pic to pic in Image Viewer, then it froze for about 4 minutes, after that I kept looking at pictures, one video and open a spreadsheet in LibreOffice Calc, it was then when it completely froze. I waited 15 min. approx, and that's when I decided to REISUB.

Update #6: @Raffa, I installed xserver-xorg-input-libinput as suggested, and repeated the test as in Update #5, with same results: the system keeps freezing, high CPU usage, RAM memory remained around 1.7G, and swap memory 0G. I did REISUB to reboot.

Update #7: @Raffa, I'm using a laptop, so the only things connected are the mouse (USB) and the power cord. I rebooted without the mouse, and tested as in Update #5 and #6, with same results, it keeps frezzing, although this time I didn't notice high CPU usage.

Update #8: @Raffa, I did the sudo apt purge nvidia-* and the sudo ubuntu-drivers autoinstall , and so far I haven't experienced any freeze. I repeated the previous test, and more, and it's been working fine. I'll post again if there's any other issue. Thanks a lot for your patience, and advice.

  • Welcome to Ask Ubuntu community. I'm using 18.04 (Bionic Beaver) from past 1 and half year. I had never faced this issue until from last month, even I've started facing this issue. I'm in the middle of debugging the issue using the logs at /var/log/syslog. You also try to find the issue. One more good news is, this month at 23rd, Ubuntu 20.04 is getting released. Hence until then try to manage or upgrade to 19.10 since you have recently upgraded to Bionic. Let's hope 20.04 will come with fix for major issues like this. – learner Apr 4 '20 at 16:52
  • Does this earlier reply help? askubuntu.com/a/1090140/307670 – 24601 Apr 4 '20 at 16:53
  • Please edit your question and add the output of ``tail -n 99 /var/log/Xorg*.log – Raffa Apr 4 '20 at 17:06
  • Hi Raffa, I've editted my question with your suggestion. – abe Apr 4 '20 at 17:12
  • tail -n 99 /var/log/Xorg*.log try now. Sorry typo. :) – Raffa Apr 4 '20 at 17:16

Diagnosis:

  • By looking into the Xorg logs, there appears some issues ( crashes ) related in particular to libinput:
(**) AT Translated Set 2 keyboard: Applying InputClass "libinput keyboard catchall"   
(II) Using input driver 'libinput' for 'AT Translated Set 2 keyboard'
(**) SynPS/2 Synaptics TouchPad: Applying InputClass "libinput touchpad catchall" 
(II) Using input driver 'libinput' for 'SynPS/2 Synaptics TouchPad' 
(**) TPPS/2 IBM TrackPoint: Applying InputClass "libinput pointer catchall" 
(II) Using input driver 'libinput' for 'TPPS/2 IBM TrackPoint' 
(**) ThinkPad Extra Buttons: Applying InputClass "libinput keyboard catchall" 
(II) Using input driver 'libinput' for 'ThinkPad Extra Buttons'
  • By looking into the output of apt policy xserver-xorg-input-*, it turns out that both xserver-xorg-input-all and xserver-xorg-input-libinput are not installed where they should be:
xserver-xorg-input-all:
  Installed: (none)
  Candidate: 1:7.7+19ubuntu7.1
  Version table:
     1:7.7+19ubuntu7.1 500
        500 http://mx.archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages
     1:7.7+19ubuntu7 500
        500 http://mx.archive.ubuntu.com/ubuntu bionic/main amd64 Packages

xserver-xorg-input-libinput:
  Installed: (none)
  Candidate: 0.27.1-1
  Version table:
     0.27.1-1 500
        500 http://mx.archive.ubuntu.com/ubuntu bionic/main amd64 Packages
  • By looking into the output of tail -n 400 /var/log/dpkg.log | grep "status installed". Some VGA related packages / drivers appear to might have been affected during the last update.

  • By looking into the output of lspci | grep ' VGA ' and sudo lshw -C display it shows you have an NVIDIA Corporation GT218M graphics card with the nouveau driver in use.


Solution:

  1. Install xserver-xorg-input-all like so:
sudo apt install xserver-xorg-input-all
  1. Install xserver-xorg-input-libinput like so:
sudo apt install xserver-xorg-input-libinput
  1. Purge the NVIDIA video drivers like so:
sudo apt purge nvidia-*
  1. Install the correct video drivers using the ubuntu-drivers tool like so:
sudo ubuntu-drivers autoinstall
  1. Reboot your machine and cross your fingers : ).

Best of luck

  • Hello Raffa, I don't have any logs starting from Xorg. In my case only Mouse and Keyboard are freezing. OS seems not freezing. I've asked a question with additional details here. Can you take a look? – learner Apr 6 '20 at 3:56
