Tried to switch to cachyOS but neither steam or rocket league notices the PS5 controller rumble function. I have already tried whatever fixes I found on reddit (eg creating a "~/.config/wireplumber/wireplumber.conf.d/51-dualsense-haptics.conf" and declaring it as a 4 speaker audio thing) and while the vibration works totally fine on the linux system itself with fftest and testing the audio outputs, steams controller test does not do anything when i click on rumble and my controller feels completely dead in rocket league. After 2.5 hours of trying to fix this I just decided to boot up windows again and it immediately works. Please tell me what the hell Im missing for PS5 controllers to work. I use the cachyos proton and bundles and everything. Also, when I try to boot rocket league on linux (steam) it has a black window doing nothing for almost a whole minute until the actual game opens! On windows I click start on steam and i immediately get the game booting.

Again, please tell me what Im missing?? Everyone says linux works totally fine for gaming but im just running into countless inconvenient minor issues that i cant manage to debug through google??

I'm relatively new to Linux so I'm not entirely sure what happened but yesterday I was playing my games just fine only to find that today none of them are launching with any Proton based commands for example "PROTON_ENABLE_WAYLAND=1" as well as the Wine DLL overrides command.

Using the game-performance and mangohud commands work fine however.

I'm running CachyOS on all AMD hardware. Can provide specifics if needed.

Hi,

for the longest time I used this pattern for envs and launcher skips:

i.e.

eval $(echo "MANGOHUD=1 %command%" | sed "s/launcher-se\/Paradox Launcher.exe'.*/AOW4.exe'/")

you know, prefix an env and match-replace (sed) part of the command

since today - and I'm not 100% sure this isn't something local - it seems that I have to wrap this in a subshell

``` $(...that line above...)

i.e.

$(eval $(echo "MANGOHUD=1 %command%" | sed "s/launcher-se/Paradox Launcher.exe'.*/AOW4.exe'/")) ```

does anyone also experience this?

exactly the title

mesa version is 26.0.99 as my vulkaninfo says

tried to clear shader cache on steam but didn't work as well. It only happens on Fedora KDE, as in Bazzite, it works fine as usual. I'm considering an whole system reinstall to check if it is some kind of Mesa bug, since I've installed (and then uninstalled) Mesa git.

I don't think the game is doing shader compilation, as it uses high cpu load

i have been distro hopping for years then i settled on using windows, until i got the linux itch again so last week i installed cachyos on my desktop pc. i usually play helldivers 2, gow ragnarok and sometimes portal 2 with my wife. for gow and portal 2 im like to use apollo+moonlight so i don't have to connect any cables to my android tv in the other room and we can enjoy gaming on big screen. the thing is i learned you can't create virtual monitors easily on linux so i looked how to do it, followed some guide and i made it but only thing was login screen had two clocks and it was constantly flickering for a few seconds. i said i can live with it and decided to not care about it, then i couldn't automatically pair my moonlight on android tv with sunshine on cachyos so i assumed it had something to do with firewall, so i disabled it to see if it works. guess what, it didn't work. after long search and good amount of chatting with gemini i couldn't figure it out so i just entered my local ip manually and it got connected so idk what the fucking problem was, anyways then i couldn't set the wanted framerate, that took like another hour to set it up yet it wasn't working half of the time so i decided wth i give up lemme play some helldivers n kick some squid ass. while downloading helldivers 2 my down speed didn't get higher than 300mbps - it was usually around 900mbps w windows- decided to not make a big deal out of it since it was still fast enough. but the last fucking drop was how BAD the performance with helldivers 2. getting frame drops every few secs while moving, if i fire any gun fps drops from 140 to 90 etc. my question is, am i uncapable of using linux for gaming or do i miss something that is common sense for all you guys? i don't wanna reinstall windows i like to search for stuff and learn it but i also got limited time cuz i work like 60 hours per week minimum, i also need to use some office stuff like libre/word/powerpoint cuz i usually do presentations related to work. please help me out, im open to all advices

So this doesn't usually happen but yes faced this graphical issue + freeze while playing Tekken 8 (hwaorang grab moment) via Steam with proton-cachyos.

Previously I did face minor freeze issues on my laptop with (any AAA game) or without gaming. A hard reset/restart was needed.

Fixed most of them by adding that Nvidia drm boot parameter as recommended on cachyos wiki along with the CPU cstate parameter 1 which seemed to fix most freezing issues. However this above one is unexpected, unique and out of nowhere. Any help will be appreciated.

Device: Asus rog strix G15QM

I call this Project The Unc Steam Machine. After many community recommendations I have decided to install Nobara over the PopOs config.

I downloaded two isos one for regular desktop Nvidia and one with a Steam os-like experience also for Nvidia.

Since I want to make this a Steam machine Uncle I tried the Steam one first and it was a flickering mess, figured I needed to update the desktop end. That was a mess and a half which led to me not being able to jump into big picture mode even on reboot.

So I decided to try the other iso the desktop only version and was able to get things on the steadier end of usable. I have steam and big picture mode load on boot. So it’s almost there, except one thing: no screen wake with a controller.

My question to the community is: does anyone know if a steam os/like nobara (my first install) have the whole screen wake with controller? Just weighing my options before reinstalling. And also how can I get rid of some of these unused uefi partitions? Starting to look like a list

Information;

running: MX Linux (Debian) on a 5.10 antix kernel.

This is a laptop gpu

Nvidia GeForce 820m gf117m

Needed driver is 390xx

Prime: not supported

Nvidia-xrun: GPU not wired to external deo output (not supported)

⚠️Forced to use bumblebee:

-----------

So I have a laptop with both integrated Intel and a dedicated Nvidia GPU, I switched to Linux a couple of months ago and CORRECTLY set up bumblebee primus to run Minecraft. But then I decided to ditch bumblebee for primus because Its better (which is a decision I regret) , I broke everything because prime isn't supported at all...

So I did everything to get my bumblebee setup back, i even reinstalled the os. But it either doesn't recognize my gpu or it gives me shit fps (like 20 compared to 60 I had first)

I have no idea how to actually fix this. I don't know what I did right on my first attempt that I'm doing wrong now

I'm really really lost and don't know what to do.

As of now I'm playing fully on integrated but it's really unplayable,

Is there actually any difference in gaming performance these days?

I know cachyos does their own custom kernel and has their own repos... but if there was some big game-changer for gaming performance then it would have been added to stock linux kernel already anyway.

Just finding it hard to believe there's really any tangible difference at all in FPS.

Considering moving to Linux, especially after fighting with Microsoft Windows 11 all morning and OneDrive. I was going to install the elementary OS because I like the way it looks. That said I know you do GOG games and Steam Games on Linux but can you do EA? I love playing The Sims, Mass Effect and the Dragon Age series. Mass Effect and Dragon Age in particular are really important to me, and I want to know I will be able to play them if I make the switch.

For the last week, I've had the issue of Steam not populating an icon in the system tray, despite being able to open and use it. After much troubleshooting, I found a fix, and I wanted to share it here in case others were suffering from it too (on KDE Plasma):

1. Have Steam open
2. Right click on system tray -> Configure System Tray
3. Under "Application Status" change Steam from "Never Show (disabled)" to "Always Show" or "Show When Relevant"

I don't know why or how it was changed to "Never Show (disabled)" in the first place, as I certainly didn't choose that, but switching it returned my Steam icon.

Note: When I first did this and restarted, Steam didn't initially autostart, despite being on the autostart list in my Plasma settings; it gave a "Failed" status in red, with no logs. However, after removing it entirely from the list, restarting, then adding it back and restarting again, Steam autostarted WITH the icon in the system tray, no problem.

Hope this helps someone else.

Bonjour, nouvel utilisateur de linux ubuntu. je viens de téléchargé RDR2 sur steam et n'est pas assez de place sur mon dur. je souhaite l'installer sur un disque dur externe 1TO que j'utilise d'habitude sous Window. Quand je veux créer un nouveau lieu de stockage sous STEAM il me dit que le contenu du dossier ne peux pas etre affiché, opération non prise en charge. Je vois bien mon disque dur externe mais quand je le choisi rien ne se passe sous STEAM. Existe-il une solution ou est ce que m'y prends mal ? Merci
