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

[efrpcabo]

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:
# inxi -Fz
# journalctl

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

[Segfault]

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

[efrpcabo]

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.

[efrpcabo]

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?

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.

[efrpcabo]

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

# apt install module-assistant
# m-a prepare

Thank you!

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

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.

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 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.

Thanks.
That means that indeed I have a Optimus (hybrid) graphics chipset.
So I have to go with the Bumblebee.

No it doesn't mean that at all. As this is a desktop it most likely is NOT Optimus. You may be able to disable the Intel graphics in UEFI/BIOS setup menu and use just the Nvidia graphics, or pull the Nvidia card out and use the Intel graphics. As this is a low spec Nvidia card you may find it works well with the default nouveau driver which saves you the hassle of installing Nvidia.
It also may work fine without the Nvidia card at all, just using the onboard graphics.
Either way you should install firmware-misc-nonfree and intel-microcode.

You have described an Intel serial device, just as it says. That is not a video device. You only have the Nivdia GPU.

Install and run nvidia-detect. That will tell you which of the different Nvidia drivers in the Debian non-free section is right for your card. You don't have to research the hexadecimal IDs. It's right in the wiki.

You can install gsmartcontrol and have it run some diagnostics on your hard drive to check its health, too. I'd do that as part of regular maintenance, anyway.

I want to use the Nvidia card because its output digital and the Intel is analogic, but I will try to disable Intel in BIOS.

intel-microcode:
I already had installed it because of another issue

firmware-misc-nonfree:
thanks for the tip!

nvidia-detect:
Detected NVIDIA GPUs:
02:00.0 VGA compatible controller [0300]: NVIDIA Corporation GT218 [GeForce 210] [10de:0a65] (rev a2)
Checking card: NVIDIA Corporation GT218 [GeForce 210] (rev a2)
Your card is only supported up to the 340 legacy drivers series.
It is recommended to install the
nvidia-legacy-340xx-driver
package.

So, I will install:
nvidia-legacy-340xx-driver

gsmartcontrol:
thanks for the tip!
