Issue

PC shuts down when gaming, no idea why, does anyone have ideas on what I can do to understand + resolve the issue? Posting here in case it's a Linux-related issue.

My best guess is that maybe the PSU is faulty, but I'm deeply ignorant on that topic and I don't know how I can verify that.

Video showing problem

Context

Fairly recently, when gaming, things work fine for a while, and then my PC randomly shuts off and I have to hold the power button off to fully shut down, before restarting.

After restarting, everything works fine, until I play a game for a random amount of time, and then it fails again.

Does not happen when not running games.

In the above linked video, the 'pop' heard is from my speakers, which maybe suggests that it's a 'power' related problem? The power-LED on my PC case stays on, but my peripherals all shut down (seen by the lack of a light on my mouse).

Inside the PC, none of the fans are spinning, and the GPU seems off (based on the lack of the light).

Specs OS: Arch Linux x86_64 Host: B550 AORUS ELITE AX V2 Kernel: Linux 6.14.2-arch1-1 Display (38GN950): 3840x1600 @ 144 Hz in 38" [External] using DisplayPort WM: i3 (X11) CPU: AMD Ryzen 7 5800X (16) @ 4.85 GHz GPU: NVIDIA GeForce RTX 3080 [Discrete] Memory: 8.82 GiB / 62.69 GiB (14%) Swap: Disabled Disk (/): 706.16 GiB / 915.32 GiB (77%) - ext4 Drivers: nvidia 570.133.07-5 Diagnosis Attempts

• I first thought it was shitty game code in Path of Exile 2, but it also happened in Blue Prince (very low requirements)
• I then thought it was to do with shitty Nvidia drviers after the 50 series release. Downgraded from 570 -> 565 drivers, didn't fix
• I then wondered if it was an X11 vs Wayland thing. Tested on i3 (shown in video), Sway and Hyprland, issue persists
• I then thought it was a 'recent games' thing, but it also happened with Death Stranding which I had played last year on the same machine with no issues
• journalctl and dmesg don't show anything interesting, either during start-up or previous (dead) boot. Happy to share the information if it's helpful though!
• I then thought it might be because the PSU wasn't getting enough power as the GPU ramped up. It was originally plugged in to an extension cable, now it's plugged in to the wall (shown in video), issue still persists

PSA for all fellow Ubuntu (and flavours) enjoyers!

If you are like me and need overstimulation from Twitch while gaming, consider switching away from Firefox Snap.

Previously I got about 90 FPS in Path of Exile 2 while watching Twitch, with a some annoying micro-stuttering. With no video content on the side I maxed out on my monitor's refresh-rate of 120 fps.
Today I got suspicious and compared a few browsers. Turns out that Twitch in Chrome keeps me on stable 120, with no stuttering. Even better, LibreWolf (FlatPak) also has no performance degradation! Stable 120 fps and proper ad-blocking <3 (of course disabled on twitch to support the people there).

TL;DR
Firefox Snap bad, use Librewolf instead and get 30% more performance for free.

I've tried almost all versions of proton on steam and it doesn't even open, it "worked" only one night and still the game closed by itself

I've searched a lot on the internet and no solution helped me and it really doesn't say why

Note: I downloaded mods on it with EA Unlocker

I'm surprised it automatically picks up any Windows game I play with Proton on Steam. I don't see any Discord Rich Presence setting in Steam either. These games are old too, so they don't have that functionality built-in either. But Vesktop can pick them up. Launching and quitting games work.

[arRPC > ipc] listening at /run/user/1000/discord-ipc-0 [arRPC > websocket] listening on 6463 [arRPC > process] started [arRPC > ipc] new connection! [arRPC > process] detected game! Call of Duty: Black Ops [arRPC > process] lost game! Call of Duty: Black Ops

However, Vesktop isn't able to pick up Linux native games. Is it because these games aren't in Discord's database or because they're Linux native? Does anyone get native games to show up on Vesktop?

It downloads the game then goes to validating and then updating files which gets stuck on 0%.

Restarted steam and my pc but the solution doesn't seem that simple because it didn't fix it.

I've been trying to play Strong Bad's Cool Game for Attractive People on Mint with the GOG installer, which works just fine on Windows.

I tried Bottles at first, running the installer and then setting up programs for each individual episode within the bottle, and it didn't work. The programs wouldn't start. Then I tried Lutris, which opened the launcher for the episodes. When I opened the first one, the logos played, and then it crashed and my desktop was all zoomed in for some reason (this fixed itself on a restart).

I'm not sure if my process (running the installer through one of the various Wine things) is the right way to go about this, or if there's something else that I'm doing wrong. Should I download a standalone exe unpacker? Run it as a non-Steam game with Proton? I'm kind of lost here. Any help with this would be greatly appreciated.

I'm a hobbyist game developer and I've just put out my first steam game's demo! My game has a native linux build and while I've tested it on:

• Kubuntu 22.04 on a Thinkpad T420 and
• Arch Linux on a Microsoft Surface Pro 8 (courtesy of a friend)

I'm interested in checking the experience on other distros / hardware configurations, mostly on a Steam Deck if anyone is willing to...

It's a classic arcade style bullet-hell, and otherwise I'm interested to hear any feedback anyone has about anything! If anyone has feedback I'd like to know what hardware / distro anyone is running,

Thank you in advance!

I installed Fedora 42, and recently a new patch for Path of Exile 2 was released. I used to be able to play normally using ProtonGE, but now the game either closes about 4 seconds after launching or gets stuck loading and never opens. I’ve tested other Proton versions like Experimental and Steam’s default Proton, but the issue persists. Other games work fine. I’m not sure if the problem is due to the system update or the game update.

Has anyone else experienced this issue?

I enjoy using my G920 to race in AC - when it works! - but I have some funky issues, frequently enough to make the experience quite annoying:

- the wheel gets stuck in a FFB mode, where it wants to turn the wheel all the way to one side (or the other) and keep it there

- if I stop the car, the wheel will still want to bounce around

- even sometimes exiting the race - or even AC altogether (the content manager), the wheel will still turn around or make random motions.

I suspect all these symptoms have the same root cause - FFB commands not getting cleared out, or the wheel stops listening to new ones.

None of these behaviors exhibit in Dirt Rally 2; just in AC. (Noting that Dirt Rally 2.0 runs "natively" with Steam Proton, whereas AC requires that whole complicated .NET install and config.)

I'm running it under Linux Mint (21 I think).

Any ideas?

I thought maybe it's a calibration thing, and saw folks (not Linux users) putting a LUT in their AC config. I tried doing that w/ Windows 10 running in a [Oracle] VM, but no dice. WheelCheck doesn't seem to do anything. I can't update the firmware using the Logitech app, because if I disconnect/reconnect the wheel per the update instructions, the VM won't recognize that the wheel has been reconnected. So I gave up doing anything via the VM. (Note that the only Win10 installation I have is in a VM.)

I recently started playing the Batman Arkham series and the game uses mouse scrolling on the edges to pan camera. I have additional screens on both sides of primary one with game in fullscreen. I could not find a way to trap the mouse in the middle screen without going into next monitor. Any suggestions?

With windows 10 expiring in October and my old PC not meeting the requirements I am considering a Linux OS rather than Windows LTSC.

I currently have a steam deck and have gotten used to the Linux desktop on there.

Is there a particular OS you would recommend?

I'm using Bazzite on a Onexplayer device. As the title, it's been working pretty well for weeks even though installed on an SD Card (btrfs) but suddenly this afternoon it no longer works. Any advice to debug/fix the crash. Also does it crash for you too or it's just me?
