Multiple applications segmentation fault when started with little to no information

Hi, I’m a pretty casual user and so I don’t know much about diagnosing and don’t have much experience with the forum.

For quite a while I’ve been experiencing segmentation fault errors in different applications when starting them. I was unable to find a solution so far.

Here is the list of failing apps:
signal-desktop
io.elementary.camera (called camera)
snapshot (also called camera)
obs (it shows a crash detected notification before segfaulting)
kdenlive

Basically all of these kept failing through updates for years, pretty sure it started happening at the same time, but it was a long time ago so I don’t remember if any major changes or updates happened then since every time I was able to find alternative applications.

All of these apps except signal seem to do stuff related to video processing recording and storing, but that is the only lead I have on this.

I have not seen any other suspicious behavior in any other apps so far.
I don’t really know how to go about diagnosing even simple stuff here, but I can provide whatever data is needed.

Running a AMD Ryzen 5 3600
Nvidia RTX 3060 Ti
Running the default video-nvidia drivare
32 GB of ddr4 ram
1tb ssd

Using gdb shows:

Thread 1 “kdenlive” received signal SIGSEGV, Segmentation fault.
0x00007ffff0ee5864 in XDisplayString () from /usr/lib/libX11.so.6

same for the other apps. This is as far as I’ve gotten.

You might be able to glean a bit more information if you start these programs from a Terminal.

Of course, it may help if you provide some system information:

inxi -zv8

… please use the code formatting (the </> button at the top of the Reply window or the three backticks ``` on lines above and below the pasted output).

Note: This output is privacy-filtered using the above command.

Cheers! :slight_smile:

Ran the programs from console and while there were some errors none seemed related to each other or the issue itself, they all just terminate with:

zsh: segmentation fault (core dumped)

Here is the inxi output:

In most cases that is an indicator of either faulty RAM or a failing power supply.

I would advise running a full memtest and letting it run for about 24 hours. But even then it may not necessarily catch hardware errors.

I’ll try, but I would imagine those being more random, in this case they all fail at boot and nearly at the same time every time, also I haven’t experienced almost any crashes, freezes, or other issues with running apps outside this list, even if they were more demanding on the system.

If it is an issue with the hardware it would most likely be the power supply as I have changed the ram sticks since the issues appeared.

Given that the power supply is indeed being taxed a lot heavier at boot time, I strongly suspect that to be the culprit, indeed.

So, the solution would be to not have the applications auto-started at boot time — your profile does not mention what desktop environment you’re using — and to not have your desktop environment start up with the applications that were open when you shut down the machine.

Well, there you have it. That seems to confirm the source of the problem. Do however keep in mind that the problem is most likely to get only worse over time.

One way of postponing the necessary replacement of the power supply is to keep your system running 24/7, and of course, this also means no suspend-to-disk, because the drive is also pulling a lot of power from the PSU at boot time, especially if it is a spinning disk drive, and the result is that the voltage drops on the other rails coming out of the power supply.

Ah sorry, I used the wrong word, by boot I meant when I start the app. Not when I boot up the pc, that’s my fault.

In that case, the problem is even worse, I’m afraid. You had better get that PSU replaced soon, then, because then it’s probably about to die. :face_with_diagonal_mouth:

Ran a memtest for a few hours, came back with no errors.
I’ve found someone with the same issue and the solution was to uninstall libva-vdpau-driver.
Seems that all the apps start normally now.

Well, that’s an AUR package. It’s not required by anything in a normal Manjaro installation. :man_shrugging:

That driver was moved to the AUR about a year ago, as it is now part of the mesa package.

It might be worth checking your system for other foreign (i.e. not in Manjaro’s repos) packages, and also orphaned packages.

To check for foreign packages:

pamac list -m

You should be able to remove any foreign packages you don’t want on your system without any issues, as they are not required for your system to operate.

You can check a package’s details and dependencies with the following command:

pamac info the-package-name

To remove a package:

pamac remove the-package-name

To list orphaned packages (packages which were installed as dependencies of other packages, but are no longer required due to the package which initially required them being removed or changing its dependencies), run this command:

pamac list -o

You can easily remove all orphaned packages (including their configuration files) with a single command:

pamac remove -no

However, before running the above the above command you should check the list for any orphaned packages which you may want to keep on your system. You can then prevent those packages from being marked as orphans by changing their flags to “explicitly installed” in the pacman database:

sudo pacman -D --asexplicit the-package-name
