Valve updated Proton Experimental for September 19th, adding their usual assortment of fixes for running Windows games new and old on Linux PCs and Steam Deck.

Read the full article on GamingOnLinux.

I have a PC that used to run Debian Bookworm, I had installed ALVR on to a Quest 2 and that PC and was able to connect and use it.

The AMD RX 7900 XTX would suffer and occasional desktop hang, which was fixed in a kernel release so I pulled the kernel and mesa drivers from backports. When I upgraded to Trixie I did make sure the backport libraries were updated.

I noticed recently SteamVR and the Quest 2 Steam Application allow a connection through the Application however each time I attempt this SteamVR connects then then throws an '450 Error, you may need to upgrade your graphics card drivers'.

Does anyone have any suggestions on what I need, or how to diagnose the issue. Most of my google results are windows users being told to update Nvidia drivers.

People on the Helldivers subreddit are saying the game is pretty much unplayable right now but that hasn't been my experience at all. This game has been rock solid for me on my Arch system over 40ish hours in the last couple weeks. No crashes, no freezing, very occasional audio issues with explosions but that's the only problem I ever have. I have a 6800xt and consistently get higher fps than my friend with a 4080 ti on Windows. I'm very curious if I'm just lucky or if the game is actually a significantly better experience on Linux.

I had previously only installed Arch on a VM and for that effect I had used archinstall - I learned archinstall is kind of crap on real hardware.

Downloaded my ISO, tried Ventoy, Ventoy booted, Arch would not boot from Ventoy - ok, no problem, I have a hundred flash drives, let's Rufus this onto one of those. Turns out Arch is reaaaaaaally specific with how you configure it's boot drive, I've never had to think twice about this step, should have been the simplest one. Wouldn't even boot. I had to change the partition scheme on the drive, and do something else, can't quite remember anymore, but I refer you to a mix of the Arch Linux install guide and chatgpt (a man's gotta do what a man's gotta do after an hour of wondering if I was too dumb for Arch - I may be). Anyways, got it to boot into the arch installer. I found this guide on YouTube - https://youtu.be/xTqOKMJdP5c?si=Sq9GoOBksD7L5V_K . It's very good, the guy explains things perfectly, unfortunately, as you will read later on, the first part of this guide didn't work for me. So, I went about trying to use archinstall. First try, archinstall doesn't launch, comes up with different errors, like a bad USB port, serial bus failure, I tried to find solutions but I didn't really see anyone with this problem. So I had to rack my brain trying to find a solution, I reran and instead of just looking through all of the errors - the function that errored out was not playing nice with my Nobara btrfs partition. Maybe I am smart enough for Arch! I nuked the partition, I wanted to wipe Nobara out anyways, just assumed Arch could work like any other installer and clear the drive before installing the new partition table. And so, after about 3 and a half hours, there it was, the wonderful, the beautiful Arch install screen. I followed my guide, and some notes I had from my VM install, I was flying through, even selection the additional packages was a flash even though I went to all corners of the alphabet. Finally it was the moment of truth, I clicked install, and the text was buzzing through the screen - my mind wandered through the possibilities of gnome customisation, through the perilous journey of installing Nvidia drivers, through the entry into the temple of Proton GE, in my mind I was Linux Indiana Jones - and then it errors out. But my dreams hadn't faded yet, Grub had installed! So I boot into Arch Linux! And it does not boot, the Grub install was corrupted. It was ok, I though maybe I had overwhelmed my own hubris in choosing btrfs again, ext4 was more my speed, and again... A corrupted boot install. My Indi fedora and whip were disappearing from my grip, but I was not yet ready to give up. On to the CLI, if archinstall won't do it's job then I will do it myself! I fly through partitioning the very thing I was most scared of fucking up, I set up my EFI to 512 mb, should be fine it's only arch! He said in his naivity, the rest goes to the filesystem - I had forgotten my swap partition, damn my eagerness, but I figured why not just create a swap file later. So I proceed, I install the base packages and the Linux kernel, I set up fstab... I chroot into the mount. I could feel it now, I could hear myself type my password into the sddm login manager screen on my cherry red switches, I install grub, gnome, gnome tweaks, sddm, I enable NetworkManager, I enable sddm - but both fail. I go into my grub install - and it works, I go into the tty, from there I manage to enable sddm. After half an hour of trying to figure out why I wasn't connected to the internet (I forgot I failed to enable NetworkManager) I was installing the catchy kernel - but my boot was out of space... NO! How?! 512 mb has never been too little for me! My dreams were shattered I was tired after several hours, but I could not fail. I splashed cold water on my face and went back to the live iso. Again I wipe the drives, set my mirrors and get into the partironing, the mounting, I install every package in a single mutiline command. And I fail to enable sddm again, but this time, this time I remembered something I had not done, I didn't enable multilib, so I do, and I update pacman, and I try again - and it works. Turns out you need to enable multilib to enable network manager and sddm.

And so here we were, armed with a far larger (I went a bit overboard I go like 2 GiB of EFI it was silly, oh well, sue me). I blaze through my installation, I get the catchy repo, the chaotic aur repo, I set my mirrors, I install the kernel and install my Nvidia drivers. I reboot, I am now on the catchy kernel. I install steam - I did it through flatpaks, maybe it was a mistake but in truth I manage to play jump space on launch, so so far so good. I game, I install more games, I try those, Helldivers, Rematch, I try everything, and it works. It works! I am gaming on arch, I did it, granted with the help of multiple guides and chatgpt, but I had head scratching moments, and I still did it!

It was 1 am by this point and I decided to go ahead and call it a night. Later I will customize Gnome, get a keyboard launcher, not sure if I will try Albert or Ulauncher, get a drop-down terminal, get my windows fonts, get docker installed so I can set up my dev environment. Set up GE and Proton Plus, maybe I will do Lutris and Heroic even though it is increasingly rare that I go outside of Steam and I despise Epic.

So, this was my Linux journey, a couple of my problems and fixes. It was genuinely hard, and tbh it took more than one day, but still. I don't know if I will ever distrohop again both because I am loving arch and because of how much work this was.

Hi yall. I'm running minecraft through prism launcher on my steam deck in desktop mode, and I've noticed some weird lag spikes only while discord is running. These spikes happen only in minecraft wether im in the menu, single player or multiplayer, and wether I'm in vc or not. I've tried disabling all mods and mod loader, disabling all resource packs, as well as changing some discord settings like hardware acceleration to no avail. Also these lag spikes happen (I think) exactly every one second for one frame, if this helps. Any help would be much appreciated. Thanks!

I have a problem with my PC where during gaming it crashed my whole linux session. I tried 2 different linux distros (CachyOS, Fedora) and still met with this same crash. ChatGPT said it is something GPU or PSU related. If you need more info please tell me in the reply

My spec: - Intel xeon e5-2680v4 - AMD RX580 - Xigmatek X-Power 3 500W PSU

TL;DR Vulkan preprocessing takes forever, BUT it does meaningfully improve gameplay as I'm on a business laptop. Is there a way to save the shaders manually?

Hello! I'm on Fedora 41 trying to play Overwatch 2 on Steam. Now I've known that vulkan shaders are often annoying, but at most I had seen it take an hour. Admittedly my computer isn't made for this, I have a lightweight business laptop, the Lenovo Thinkpad X1 Carbon. Lovely device, but not for gaming. Still, I do regularly play games on it, and I guess this one is more demanding than what I had tried before (?) in any case, it takes around 7 hours for it to process Vulkan shaders. I do notice a performance difference tho so I don't wanna skip it.

Now if it was a one and done thing I wouldn't mind. But it does it after EVERY update, and, worse yet, it seems to do it after every library install on my laptop. I'm a student, so I'm constantly having to install libraries and new software. But when I do, the game won't launch,, instead steam "verifies" the install (also takes like 2h btw...) and then back to vulkan shaders I go.

Now I'm guessing the verifying thing is just bc it's a competitive game. But is there no way to save the Vulkan shaders permanently? And if so, why isn't that the default?

Thanks :)

Sorry for the bad photo. I am trying to run peak on a Thinkpad(T490) it is freezing on the settings so I can't change ingame settings, the music and home screen grafics seem good but I can't start a game(offline or online) if you know anything that can help me I would love it if you comment!

Anyone encountered this issue yet? I wanna know if it's just my Distro or if it's affecting others. I use NixOS BTW.

PC Specs:

CPU - Ryzen 7800x3D
GPU - Radeon 7900XTX
MOBO - B650
RAM - 32GB DDR5 6000

This is a pretty recent install as I do fresh installs quarterly basically, keeping all my data in the cloud. That said, because I just did it, I really would prefer not to have to again so soon.

I'm using the basic mesa AMD graphic drivers, not the git version.

I discovered today that whenever I try to boot an Unreal 5 game, it just won't boot.

The two games I've tested are Borderlands 4 and Lords of The Fallen, both of which I've played on this install before without issue.

By default I use Proton-GE (latest), but to be sure I've a bunch of different Proton versions to run BD4 again, including by not limited to CachyProtonSLR (forgive if that's not the actual name), Proton 9.0-4, Proton Experimental, Proton 10-15 (Beta). All yield the same results.

For Lords of The Fallen it shows the Easy Anti-Cheat Prompt, and then just sits with nothing happening for about 60sec until it stops and Steam prompts the option to "Play" again. My GPU spins up like it's running, but the application never shows in my task bar like usual.

For BD4, it just spins up for about 5-10sec, then stops just like LoTF. Application never appears in the task bar. Switching to Proton 10-15 (Beta) it does show this prompt, but I can't find anything on it from the last 5 years basically, which is pretty useless.

The link takes you hear which is useless.

Other games I've played recently like PEAK, REPO, and Astroneer boot up fine, not issues.

I just need someone to level with me, is my boot cooked, or is this fixable.

I use Debian 13.

I installed Rocket League and everytime I want to use my controller to play it I need to delete it in the bluetooh settings before repairing it again and again until the buttons are mapped right or my "y" button makes the car drift instead of activating ballcam and my "x" button just does nothing. And let's not talk about the bumpers.

I went into the controller settings in KDE plasma and saw the mapping wasn't the same as before so it's probably got something to do with that. It's not a heroic game luncher specific issue either cause the buttons have the same problem when I launch a steam game.

So how do I make my button mapping consistent between boots. I've heard about xboxdrv and xpadneo. Are those relavant? I mean my controller connects and works, there's rumble and everything it's just that the buttons aren't consistently map between boots.

Hello! I’m just writing this for all those that might have the same problem I had, and hopefully this fix helps.

If your DualShock 4 feels really laggy over Bluetooth on Linux, the issue is often BlueZ’s input plugin capping the controller to ~40 Hz poll rate (about 26 ms between reports though the numbers may vary).

After switching to the hid_playstation driver and disabling the BlueZ input plugin, the controller runs much smoother. It now adapts between ~40 Hz and up to ~500 Hz. In other words, it sits around 2 ms (500 Hz) when you move the joystick quickly, and goes up to around 26 ms when idle to save battery.

Again, these numbers can vary depending on your controller model, kernel version, and Bluetooth adapter I’m just sharing what I saw from my testing.

Wired USB stays rock-solid at 125 Hz (8 ms), and I suspect it could be even better with a decent micro-USB cable (I tested with a cheap decade-old one I had in a drawer).

Bluetooth is now actually playable and in some cases, even faster than wired, if you don’t mind a bit of variability instead of a rock-solid fixed rate.

System

Arch linux on kernel 6.16.7-arch1-1

Steps

Edit /etc/bluetooth/main.conf and set under [General]:

#This is optional it is always making sure that the controller uses classic bluetooth not the LE ( low energy) because it "might" give worse performance

ControllerMode = bredr

#this is the most important one which it disables the bluez input plugin and lets the kernel handle hid devices in this case it lets hid_playstation handle it.

DisablePlugins = input

The ControllerMode = bredr setting is optional. It helps ensure the controller performs optimally during heavy gaming. However, most users should keep it at the default. Because, Many peripherals rely on Bluetooth Low Energy (LE) to save battery, sending small packets only when needed instead of streaming data constantly and others. By leaving it at the default, BlueZ can automatically switch between classic Bluetooth and LE for devices that use low energy. I hope this helps at least one person! If not, it will still be a good reference for me to remember what I did in case I switch some settings and forget how to make it work again.

I play games like elden ring ff7 rebirth and Minecraft, and one thing that all of those games have in common is that sometimes I get hit by lagspikes/stutters at the most unexpected times which ruins the mood of the games I play (Especially elden ring)

Things I have tried to solve the issue: - put the governor on performance - closed most of the apps in the background - used gamemode - used proton-GE - see temps (CPU is at 80 and GPU is at 70-75) - set both monitors to 60hz - disable vsync in games - install intel-ucode package

I am stumped at this point and I want to see if someone had this problem before and if they got a fix or a remedy for it?

Specs:

OS: arch linux

Kernel: linux 6.16.7-zen

Monitors: dual, one 60hz and one 75hz

GPU: rtx3060 12GB

CPU: Intel 11th gen i7-11700F

DE: Kde Wayland

Drivers: Nvidia-open-dkms

Ram: 32GB
