16.04 Freezes and then after a wait unfreezes

[Robbyx]

I would like to resolve this long standing problem. Following a similar query elsewhere, here is my output from the commands recommended in that query. Does the following help indicate why I am having the problem. It happens randomly but particularly during playback of saved mp4 videos. I am also often getting gnome shell crashes, that I reload via command r

[cruzer001]

Have you tried the generic kernel?

[Robbyx]

Yes. The generic kernel also crashed.

[cruzer001]

I had a look around and have found older reports of failure, but the kernel your on has support for Kaveri graphics running the Radeon driver.

https://help.ubuntu.com/community/RadeonDriver

Are there any crash reports in /var/crash; /var/log/apport or /var/log/kernel.log?

You could also try the 18.04 live dvd and see if there is any improvement.

[Robbyx]

Would you mind giving me a grep command line for crash and kern.log? They are too big to post here and crash is hardly scrolling when I open it.

Apport .log.1 says:

[cruzer001]

Last 100 lines is good.

tail -100 pathtofile > nameoflog

example:

tail -100 /var/log/kern.log.1 > kernel_log
You now have a file in your Home directory called "kernel_log".

An easy way to post this log is to install pastebinit:

sudo apt install pastebinit
and then

cat ~/kernel_log | pastebinit
Then wait for it and (still in terminal) it will return a link. Just post the link.

https://help.ubuntu.com/community/Pastebinit

[Robbyx]

Thank you for your command line to help get the log files that should help resolve my freezes. I tried to get pastebinit to work but no url was forthcoming. I therefore post here the Last 100 lines of Kernel.log.1

Re /var/crash
The files in this directory were mostly 0 bytes. There was one today that was 46.8MB but it was not a text file, so I have not posted it When I opened it, the output looked like this extract:


15ySp9vMQHhU27cT9iuVC/neZePjoCPLzgJD/ERMPrx8h/a/hmzXKfuKNUdKrYYxGu06E9M+OkL/udKc73elOd7rTne509//RObcHK+g2Ze8u3elOd39njrT/HXr7153u/m7bf6pBb/+6053udKc73f1duf8ElV+lWgAQCRs=

There was another dated 27 Aprl that had 2.7mb it had text. Here are the last 100 lines

What I haven't hit on is a good answer, but then my search time is limited.

The newer kernel/gnome may work better for you. Have you considered trying 18.04? You could burn a dvd and try without installing.

You could also try a different window manager on your current install as a temporary solution.

sudo apt install gnome-session-flashback
At the login screen click on the gear and choose "Flashback (Metacity)"

Not the best answers, but all I have to offer at the moment.

Thank you for trying and for the advice. I am considering 18.04 but as I am on LTS that version is due out later. in the month. I will try flashback and see if that is an improvement.

18.04 is out now: I have been running it on 3 machines for over a week now.
