Hello, I am trying to run games on a fresh Ubuntu 25.04 install. Whenever I launch games that use proton they will stop responding for about 45 seconds and then load like normal. Any idea what's causing this? It's very annoying as it happens every time I launch the games. I have ensured my graphics drivers are up to date.

Specs:

RTX 4070 Super

9800X3D CPU

32Gb DDR5

Ubuntu 25.04

Any ideas?

So for whatever reason on LMDE I lost the ability to play Robocop on steam. Tried different proton versions and Ge proton versions but it still wont launch. I already beat the game but wanted to replay it. So I have two puters on my desk, a sff with a 3070 and a 57003xd and my main rig with a 4070 super ti, 58003xd. Both were running LMDE but haven't used the little guy in awhile. I have never used an arch distro. So I said what the hell and installed Cachy OS on the little guy. After install I downloaded a meta gaming package offered by Cachy OS. Installed steam, downloaded Robocop, used cachy proton version and Robocop booted right up. Its a rolling distro, have never utilized one and its my first arch distro. Now I'm thinking about trying LMDE SID. What would be the best way to transition from LMDE to LMDE SID? Or should I try LMDE Trixie? Thanks for any tips

So yeah as you can see MangoHUD tells me my Radeon RX 7900 XTX is thermal throttling. After removing VSync and setting the FPS cap to the maximum the GPU doesn't reach 100% utilization but as you can see at the top left the temps are fine. I took Subnautica here as exaple but it also happens in other games. How can I fix this?

System Information:
Linux Mint 22.1 Cinnamon with Linux-Kernel 6.11.0-29-generic

CPU: AMD Ryzen 9 7950X3D

GPU: AMD Radeon RX 7900 XTX, AMD Radeon Integrated Graphics (second screen)

MangoHUD and Steam are installed as Debian Packages

Proton Version: Proton Hotfix

When I try to launch it gives me a disk write error to somewhere in steamapps/downloading (2180100/files/lib/i386-linux-gnu/libdav1d.so). It doesn't happen when actually downloading. Removing the data there or resetting download cache did nothing. All the files there are owned by me. It's an ntfs volume mounted with the ntfs3 driver instead of FUSE. But that's not the problem because it worked earlier today and I didn't update anything. I get no log errors.

I did mess a bit with steam, deleting steam from my games partition and reinstalling it because many core steam files corrupted, including proton experimental which I couldn't fix at all. But I didn't do any workarounds the first time.

I'm on OpenSuSE tumbleweed 20250702.

How do I fix it?

Edit 1: When waiting for an answer, I got a similar error with enter the gungeon, but it was 2805730/files/lib64/libdav1, which seems related. It didn't happen with any other games though.

Edit 2: It happens when I use proton hotfix or play balatro.

Fastfetch for system info

The games freeze after a random amount of time, usually less than an hour. if they're full screen I have to hope that Alt + f4 works, if they're windowed I can close them from steam with a little patience.

they often hang after periods of inactivity, but still freeze while I'm playing if I go for long enough.

There are more games than just this one

A dev sent me a linux folder and I got the game to run by giving the files permissions but I have no sound. I'm new to linux (mint) and I feel like I'm missing a step, can anyone help me out?

Hello! I am trying to launch flawless widescreen alongside battlefield 4 so I can utilize the FOV hotfix that comes with flawless widescreen. To do that, I am trying to launch the FlawlessWidescreen.exe in the same prefix as that of Battlefield 4. Using:

protontricks-launch --appid 1238860 FlawlessWidescreen.exe

But it refuses to launch when Battlefield 4 is open. And I get the following error:

/usr/lib/python3.13/site-packages/protontricks/util.py:11: UserWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html. The pkg_resources package is slated for removal as early as 2025-11-30.

It refuses to launch when Battlefield is running. And to add insult to injury, it opens fine when Battlefield is closed. And it works the other way around too. When I open flawless widescreen before battlefield, then it is battlefield that refuses to launch. It seems as if there cannot be two programs running under the same prefix.

Help!!!

Just installed Fedora 42 KDE Plasma and I have been having a smooth experience so far. The only hiccup is with gaming when I am launching EA titles like Jedi Survivor.

The steam overlay hooks to the EA launcher when it says "game launching" instead of the actual game. I've tried a bunch of commands in launch options and installed a few things like gamescope but it still attaches to the EA app.

Any ideas on how to fix it? The game itself runs fine so no issues but i'd like to see my fps and stuff so I know if i need to tweak anything

I installed Prism Launcher from flatpak and Discord won't detect it. How can i fix this? I went in the add game menu but even there i couldn't find Minecraft or Prism Launcher. Also i got Discord from the official .deb file because the flatpak version has problems with detections so dont tell me to get the .deb version.

I was curious how Linux is for gaming so I thought I'd give it a shot. I actually started with Pop OS on my Surface 3 Pro (very old) just to see what it was like. It improved performance significantly. So I went ahead and installed it on my main PC and "it just worked." It installed properly, installing the nvidia driver was super easy. I was really enjoying it but there were some things that were annoying. The POP OS Store always runs an update check when you open it which I was doing constantly. It was also slow and laggy with searches and found myself using apt searches to find stuff. Later I found out there is the Cosmic store which fixes all this. Also I was having random lock ups which sometimes would be for a short while or would require a reboot. Gaming I only tested a few things. I ran Unreal Tournament 99 in Heroic Launcher and was shocked how easy it was to add a game exe and just start playing. I also tried Doom 2016 which ran great. It was a bit clunky to get going as it had to do a ton of downloads then didn't launch. Quick check on Protondb and I saw I had to change the version which is easy to do under Steam's game properties with a drop down menu.

However the naggling issues caused me to look elsewhere. I was lured in by a graybeard in a youtube video to try Open Suse. Well I was lured by his video and some reddit threads, the gecko looked cool too. I tried it and ended up with a black screen after installing the OS. I later learned this was most likely because of the Nvidia driver or lack thereof.

So it was on the distro #3. I was going back and forth between Bazzite and Cachy and went with Cachy. I followed a youtube video to go through the install and ended up again with a black screen after installing the OS. I tried searching around and saw it was most likely the Nvidia driver. So I went through the installer again, chose grub instead of the default option, and stuck with default selections and this time I was able to boot into the OS! I ran the meta command and was on my way. Gaming worked just as well as in Pop OS. I was able to connect my xbox one controller wired but not wirelessly but I think thats because its paired on the windows side. I don't have any random lockups yet. The gui for the repo in Cachy is Octopi which is a bit clunky but works. So far so good. I might stick with Cachy for a bit and do some actual gaming now.

I will say that people saying you don't need to use the terminal are incorrect. You don't need it until something goes wrong and then you do. For example both distros muted my audio at the hardware level. I use a Pyle mixer connected over USB for my audio. I had to learn about the Linux audio stack and drill down through the layers until I learned about the alsamixer command. It was here I was able to choose my audio device and saw the volume was either muted or too low and turned it up. The GUI sound controls do not control audio at this level so it must be done via the terminal.

I need to do this to run some mods for Doom. I'd like a GUI program for this, but it seems it might not exist. I have a good bit of mods and really want an easy way to do this. I'm using Linux Mint Cinnamon.
