SOLVED Buster XFCE: How to find the cause of random crashes?

Postby efrpcabo » 2019-08-28 18:50

Hi,

How can I find the cause of random crashes?

I don't really know if this technically is called a crash.

What I am experiencing is this:
- I am working normally at the computer
- and suddenly all windows close
- and the login screen appears (when we introduce the username and password)
- there is no freeze whatsoever
- this happens when I am using apps like Firefox, Thunar, Virtualbox, etc
- but the only app that I was always using in every ocasion was Thunar
- however, I don't know if Thunar is the cause because I am using it almost all the time
- so it could happen without it being the cause also

Before I was on Debian 8 Jessie XFCE and this never happened.

Now, I'm on Debian 10 Buster XFCE for a couple of weeks.
And since then I have experienced multiple crashes.
Here are just a few from the last days.

How can I investigate this?

I have googled and found out that there are many cases of crashes, in a multitude of distros: Debian, Fedora, Arch, etc.

But almost every case reports "freezes", i.e, the system freezing, and in my case that doesn't happen; never did, not even once.

What happens is I am just logged out of my session and the login screen appears (when we introduce the username and password), like I said above.

From my google searches, I've seen people advising to analyse this files:
/home/user/.xsession-errors.old
/var/log/lightdm/"various logs"

and analyse the result of this commands:

How can I investigate this?
Am I looking at the right files?
Has someone else having the same issue?

Every time I see IO errors I start with checking the health of hard drive.

Ok, that's a good idea.
I can move my system to another disk for some days and see if the crashes stop.

Other ideas are also welcome.

I just had another crash some minutes ago.
I was gathering all the information I could about this last one.

The crash occurred before 21:01:05.

There are 3 IO errors at 21:00:48, but they don't seem the cause; or do they?

Re: Buste XFCE: How can I find the cause of random crashes?

You can run lots of tests on your hard drive without removing or replacing it. Also I suggest you learn how mcelog can serve you.

Thank you!
I will learn about mcelog.

It appeards "mcelog" was replaced in Debian Buster by "rasdaemon".

Also, when I try to install "mcelog" in Synaptic, it doesn't appear.
But instead it appears "collectd-core".

What should I do now?

If you have no overriding objections to proprietary software, you could test the Nvidia graphics driver from the non-free section to see if that makes any difference. Follow the directions in the Debian wiki, though I prefer using module-assistant to set up the build environment:

Code: Select all
# apt install module-assistant
# m-a prepare
The MX Linux repositories: Backports galore! If we don't have something, just ask and we'll try--we like challenges. New packages: Calibre 3.48.0, QMPlay2 19.09.03, wine-staging 4.16, Telegram-desktop 1.8.8, Pale Moon 28.7.1, Waterfox 56.2.14

This comment of yours made me expand my observations into the hardware realm.

And after some hours I remembered that I had changed the sata port of my system hard drive some time after installing Buster.

That happened when I decided to disconnect the DVD drive and use to connect another disk.
When I did that, I had disconnected all the sata cables and then connected them all again, but not exactly the same.

So, my system hard drive got connected to the sata port that was used by the DVD drive.
At the time, I didn't worry about that, but after this comment, I started thinking and investigated.

This port happens to have another color (black), while the other 3 ports are red.
Also, in BIOS is shows up as eSata instead of just Sata.

So, I connected my main drive to another red sata port, and one of the other disks to the black one.
And until now I hadn't another crash, and I am working a couple of hours.

It's still early to take conclusions, but this is the point of situation for me now.

Hmmm. Sounds very much like what I was experiencing here. Although the thread related to KDE I have a parallel installation with XFCE and it does the same thing. Jessie and Stretch installations are rock solid.

in terms of hardware the only common factor between my machine and OP's is the same video card and nouveau driver.

One Google search result I read suggested changing USB connections to different ports. I've done that and frequency of the problem has dropped substantially, but not stopped altogether.. To be honest, I can't see that it could be hardware, simply because the problem simply does not occur when I run Jessie or Stretch. However, that doesn't eliminate a kernel or driver change interacting differently with the graphics card and killing X?

As the crashes came back, the cause wasn't the eSata port :(

Thank you.
I have read the thread and it seems similar.
I've asked there if the OP had found the cause.

If I can't solve this soon, I think I'm going to Stretch.

The directions on Debian Wiki say this:
----------------------------
Identification
The NVIDIA graphics processing unit (GPU) series/codename of an installed video card can usually be identified using the lspci command. For example:
$ lspci -nn | egrep -i "3d|display|vga"
01:00.0 VGA compatible controller [0300]: NVIDIA Corporation G80 [GeForce 8800 GTS] [10de:0193] (rev a2)

if this lspci command returns more than one line of output, you have an Optimus (hybrid) graphics chipset:
https://developer.nvidia.com/optimus
and the instructions on this page do not apply to you
Check the Bumblebee page instead:
https://wiki.debian.org/Bumblebee
----------------------------

So, I ran the command:
# lspci -nn | egrep -i "3d|display|vga"
And my outuput is:
00:16.3 Serial controller [0700]: Intel Corporation 8 Series/C220 Series Chipset Family KT Controller [8086:8c3d] (rev 04)
02:00.0 VGA compatible controller [0300]: NVIDIA Corporation GT218 [GeForce 210] [10de:0a65] (rev a2)

Does this mean I have a Optimus (hybrid) graphics chipset?

The reason I ask is because the "3d" appears only in the last field: [8086:8c3d]

Also, I am experiencing this on a Lenovo ThinkCenter Desktop and Bumblebee seem aimed at laptops, like stated on Debian Wiki here:
https://wiki.debian.org/Bumblebee

"Bumblebee aims to provide support for NVIDIA Optimus laptops for GNU/Linux distributions. Using Bumblebee, you can use your NVIDIA card for rendering graphics which will be displayed using the Intel card."

The answer to my question is important because the the procedure is different for "yes" or "no":
Yes:
https://wiki.debian.org/Bumblebee
No:
https://wiki.debian.org/NvidiaGraphicsDrivers

Fields on the end (in your case [8086:8c3d] and [10de:0a65]) are not word/abbreviation/acronym descriptions of devices. They are hexadecimal numbers, identifiers in format vendor:device.
