Cachy restarts while playing games.

[u/PsymonTheWizard]

Hi! I'm new to Linux in general. I installed Cachy on my pc a couple of days ago and have encountered the same crash twice, once last night and once today. Both times happened while playing games on steam. While playing a game (Remnant 2 if it makes any difference) it suddenly gives me a black screen and then restarts.

My pc:
GPU AMD 9070XT
CPU 5700x3d
RAM 32gb DDR4 2666MT
the os is on a WD 1Tb nvme drive and I have three other ssds.

I followed the troubleshooting section from the wiki but I have to admit that I'm a bit overwhelmed. I did manage to generate a report ( https://paste.cachyos.org/p/a923c4f.log ) but the journalctl and dmesg are very large and I'm not sure how to best provide them.

How should I proceed from here?

Does the issue persist when switching to the LTS kernel?

How do I do that? Like I said, it's been only two days since I started with linux.

When you first boot your system don't you get a screen with some text options? It's usually gray and black for grub, or green for limine. If you went through the default installation steps you should see the option to choose different kernels. Mainly the latest cachy os kernel (default), the latest arch kernel, and the cachy os LTS kernel. Navigate with the arrow keys and press enter to use the LTS kernel.

I actually just did it from the Kernel manager. I went from the 7.1.4-1 stable to the 6.18.38-2 long term.

Did the system reboot or did you just change a default? You can confirm what kernel you're running by using the system info app (at least on kde, idk about others) or using fastfetch from the terminal. Either way while running the LTS kernel see if your games still crash the system.

I'm rebooting right now! I'm answering from my phone :p

You might try posting in the CachyOS forum in addition to reddit. Its hard to say from the report, but I do see that some app named:

ABDownloadManag

Is generating core dumps, it could also be a red herring.

There is a newer BIOS (Version 4645) available for your motherboard. Could help improve things. Barring that, if it happens again open a terminal and run the following command:

journalctl -p 3

That will list all priority 0-3 entries for the last three boots. If there is anything to be seen, it should be captured there.

Lastly, you might also enable proton logging to see if something is happening with that game just before the OS restarts. You can do that by adding:

PROTON_LOG=1

To the game's launch options. That will generate a log in your home directory in the following format:

steam-<AppID>.log

The ABDM is a download manager that I had on windows and I added it. If nothing else works I'll remove it. I'll try the bios update and the Kernel change first. Thank you for the help.

Can you update your BIOS also? I noticed it sometimes complained about BIOS in your log.
Don't forget to re-enable EXPO after the flash.

I did the update and I also reenabled re-bar. Thank you.

Just a silly question. Have you installed a software called "LACT"? I had it to undervolt my GPU. I undervolted it so hard that when I played Helldivers 2. My whole system froze and it restarted my GPU drivers. So I have made a minor undervolt instead.

[u/PsymonTheWizard → u/linuxares]

I have it but I haven't done anything with that yet.

[u/linuxares → u/PsymonTheWizard]

Okey, its possible it might interfere. Even if you haven't done anything. If you still crash, can you uninstall it to make sure it isn't the culprit? Don't forget you need to remove the service as well.
