andI was planning migrate to Linux for some time and now, since i bought my first AMD GPU, i started to migrate.

I already installed other softwares and import many configs and files to the Linux version and already tested few games and they are running pretty well, the thing is than i have two giant modlists (+600 mods) for Skyrim Special Edtion and Fallout Tale of Two Wastelands ( i also have a farly big modlist on Morrowind but is on OpenMW, so no problem).

My question is there is a way to bring my modlists and MO2 to Catchy OS or am i cooked ?

I'm new on linux for gaming and appreciate any help

Does anyone else find themselves slightly disappointed with Mesa 26.0.1? I have a 9070 XT and thought this release was supposed to improve ray tracing performance, but I'm still getting the exact same performance in Assassins Creed Shadows and Cyberpunk 2077 that I was with 25.3.6 on Cachyos. Which is about 20 to 30 fps lower than what I would get in Windows.

So I have an old Asus UX370UAF, which is an ultrabook with an Intel HD 620 as GPU so nothing powerful.. but I mainly play light stuff like The Binding of Isaac, Dead Cells, Risk of Rain 2.. I tried playing my Steam library on Ubuntu 25.10 and all's good but I was wondering which distro could improve performance on such device, taking into account that, apart from gaming, I use it daily for light browsing like netflix and youtube

Holy shit have things improved. I used Linux, mostly Ubuntu from 2009 to like 2015 because Windows Vista ran like dog shit on my laptop at the time and I couldn't afford a PC at the time (laptop was HS graduation gift).

Back then, gaming sucked, you had very few choices. You could play open source games, some of which had multiplayer, but it felt like 80% of them were Quake/UT clones. You had some other clone open source games involving Tux, and you could get some other older games to natively run, but there weren't a lot of options. You could run games with Wine, but have fun messing with configurations and commands for hours to get it to run. Some played without issues, but there was always a setup. Then Desura came out and it opened the doors to indie game developers releasing more Linux native games to distribute, and it was a small improvement, but a lot of indie games back then weren't...good. They ran, but weren't fun.

Then Steam launched their Linux native client after speculation and leaks, it had issues, but it helped to motivate some developers to make Linux native versions, but if you wanted to run games that could only use Windows, well you could run the Windows client with Wine, and hope stuff worked. It did, sometimes, and sometimes you'd spend hours dicking around to get shit to run.

You also had to deal with graphics drivers, open source and closed source came with their own pros and cons. My laptop at the time had an ATI (pre-AMD) 256mb GPU. At the time Nvidia proprietary drivers gave the best performance.

Windows 10 came out and I used that with my first gaming PC. It ran a GTX980 and it served me well. Also ran Win10 on my 2nd build with an RTX3080. I liked Windows 10, then Windows 11 came out and it felt like dog shit on my work computer. It's glitchy, and there's some basic ass bugs, like the taskbar crashing of all things. I also got a Steam Deck at launch and watched how much work Valve put into Proton. Gaming on Linux had made huge strides, it was easier to build a better compatibility later than to get developers to make native ports I guess.

I tried to run CachyOS on my 2nd gaming PC and I had to run DX12 games like FF7: Rebirth at lower resolutions because I guess Nvidia performance didn't keep up over the years. I wiped again it to reinstall Windows for when I rehome it, and I did some research and found out AMD GPUs played nicer.

So, I built a 3rd PC. 9800x3d, 9070xt, 32gb DDR5 RAM. Installed CachyOS, and everything JustWorks™. I clicked one button for gaming packages and ran one command for some meta packages which I don't really know what it did. I don't have to dick around with configurations, I just click the install button in Steam, then click play, and it just runs. I could play FF7:Rebirth, I could play Stalker 2 maxed out, and I could play Resident Evil 9 on launch day without doing anything (well I did have to put a launch option in so it would stop hiding ray tracing options). KDE is nice too, I used to not like it because of how much more customization you could do in Gnome, but I don't care anymore, KDE offers a much better out of the box experience, I just want to play my games. Sorry for the long post, I liked Linux when I was younger, but as I got older I didn't have time to mess around or fix things as it had issues, so I'm just glad to come back to something after 10 years of improvements.

Also, I guess I can say this: I use Arch btw.

I have issues with VR games not streaming correctly, I tried different encoding and streamers, but it is always the same. I also have encountered artifacting in Elite: Dangerous which is the same as in this post. I'm running RX 7900 XTX with Mesa 26.1.0 on CachyOS. Any ideas?

Last time I tried this controller under Linux it did have support in the kernel, but for all games I tried playing buttons were reversed. Has this been resolved?

I've been struggling to get this one going.
To the point I've attempted to leverage AI's help.
I've tried the few commands I've seen on ProtonDB, focusing on people also using an Arch-based distro.
I should note, I'm still rather new with Linux. I've only been using it ~2 months or so.

For the sake of attempting to be as concise as possible, I have utilized an AI tool to create a bug report to document the various things we'd gotten into trying to resolve this. I appreciate the formatting that the AI used as it feels concise. Starting here:

# Tom Clancy's The Division 2 – Linux Bug Report

**Platform:** Ubisoft Connect (non-Steam version via Lutris)

**Date:** February 28, 2026

---

## System Specs

| Component | Details |

|-----------|---------|

| OS | CachyOS Linux (Arch-based) |

| Kernel | 6.19.3-2-cachyos (NTSync built-in) |

| Desktop | KDE Plasma 6.6.1 on Wayland / KWin (XWayland) |

| CPU | AMD Ryzen 7 9800X3D (16 threads @ 5.27 GHz) |

| GPU | NVIDIA GeForce RTX 5090 [Discrete] + AMD Radeon [Integrated] |

| NVIDIA Driver | 590.48.01 |

| RAM | 60.46 GB |

| Proton | GE-Proton10-32 (also tested: Proton Experimental, Proton Hotfix, Proton 9.4) |

| DXVK | v2.7.1 |

| VKD3D-Proton | vkd3d-1.1 |

| Wine | 10.0 (via GE-Proton) |

---

## Summary

Game launches and progresses through EasyAntiCheat initialization and Ubisoft Connect authentication successfully, but consistently deadlocks during the in-game loading screen — freezing between 7–10% — due to a kernel-level NTSync deadlock triggered after the game's WebSocket connection to Ubisoft's notification servers fails.

---

## Launch Methods Attempted

**1. Steam** — via Steam's built-in Proton compatibility layer (multiple Proton versions)

**2. Lutris** — via Lutris 0.5.22 with GE-Proton10-32, Ubisoft Connect runner

**3. Direct command line** — bypassing both Steam and Lutris entirely:

```bash

PROTON_LOG=1 DXVK_FILTER_DEVICE_NAME="NVIDIA GeForce RTX 5090" DRI_PRIME=1 \

WINEFSYNC=0 WINESYNC=0 PROTON_USE_NTSYNC=0 \

WINEPREFIX=/path/to/wineprefix \

STEAM_COMPAT_DATA_PATH=/path/to/wineprefix \

STEAM_COMPAT_CLIENT_INSTALL_PATH=~/.local/share/Steam \

STEAM_COMPAT_APP_ID=0 SteamAppId=0 \

~/.local/share/Steam/compatibilitytools.d/GE-Proton10-32/proton waitforexitandrun \

"/path/to/UbisoftConnect.exe" 2>&1 | tee ~/proton_log.txt

```

---

## What Works

- Ubisoft Connect launches and updates successfully

- Login and authentication succeed

- EasyAntiCheat initializes successfully:

```

[EAC Bootstrapper] Launcher finished with: 301, 'Easy Anti-Cheat successfully loaded in-game'.

[EAC Bootstrapper] Successfully initialized the Easy Anti-Cheat module, waiting for game window to become visible.

```

- GPU correctly identified as RTX 5090 (required `DRI_PRIME=1` and `DXVK_FILTER_DEVICE_NAME` to override AMD iGPU default)

- NVAPI initializes correctly

- Vulkan swapchain created at 3840x2160

- Play session with Ubisoft servers starts successfully:

```

Play session (1) successfully started for game 4932. Should be updated in 330secs.

```

- Game renders frames briefly (207fps detected before deadlock)

- Audio plays during the deadlocked loading screen

---

## What Fails

The game consistently freezes at 7–10% on the in-game loading screen. Process analysis confirms a kernel-level NTSync deadlock:

```bash

cat /proc/$(pgrep -i division)/wchan

# Output: ntsync_char_ioctl

```

This deadlock occurs reliably after the following WebSocket failure appears in the launcher log:

```

[WSConnection.cpp] Received Http status code 0 for url

wss://public-ws-ubiservices.ubi.com/v2/websocket?SpaceIds=...

```

Multiple HTTPS calls to `public-ubiservices.ubi.com` also fail with socket error **10060** (TCP connection timeout) from within the Wine environment, even though the same endpoints are reachable from the Linux host directly.

---

## Attempted Fixes

| Fix | Result |

|-----|--------|

| `WINEFSYNC=0 WINESYNC=0 PROTON_USE_NTSYNC=0` | NTSync still active (CachyOS kernel overrides) |

| `sudo rmmod ntsync` (unload kernel module) | Game falls back to `futex_wait_multiple` deadlock instead — same hang, different syscall |

| `sudo modprobe ntsync` + relaunch | NTSync deadlock returns |

| `winetricks winhttp wininet` | No change to WebSocket/HTTPS failures |

| `DRI_PRIME=1` + `DXVK_FILTER_DEVICE_NAME` | Fixed wrong GPU selection (iGPU → RTX 5090) |

| state.cfg: `windowed=true`, reduced resolution to 1920x1080 | No change to loading freeze |

| state.cfg: `dx12=false` | No change |

| Proton Experimental, Hotfix, 9.4, GE-Proton10-32 | All produce the same deadlock |

---

## Key Log Evidence

### launcher_log.txt — WebSocket failure (always present before deadlock)

```

[WSConnection.cpp] Received Http status code 0 for url

wss://public-ws-ubiservices.ubi.com/v2/websocket?SpaceIds=

e17be87d-2996-4f3b-97c4-19bb2dae2933,...

&NotificationTypes=upc_remote_actions,FRIENDS_STATUS_CHANGED,...

```

### launcher_log.txt — HTTPS timeout with socket error 10060

```

[PlaySession.cpp] Cannot start play session for game 4932.

JobResult: NetworkFailure (4). ResponseStatusCode: 0.

SocketErrorCode: 10060.

URL: https://public-ubiservices.ubi.com/v1/profiles/.../playsession/api/sessions

```

### wchan — NTSync deadlock

```

ntsync_char_ioctl

```

### wchan — Without NTSync module loaded

```

futex_wait_multiple

```

---

## Root Cause Theory

The game appears to block its main loading thread waiting for a response from Ubisoft's WebSocket notification service. When this connection fails (as it consistently does under Wine/Proton), the game does not time out gracefully — instead it deadlocks indefinitely on an NTSync (or futex when NTSync is absent) synchronization primitive. The underlying Wine HTTPS/WebSocket stack is failing to establish connections to `public-ws-ubiservices.ubi.com` despite the host system having full connectivity to the same endpoints.

---

## Questions for the Community

1. Has anyone successfully resolved WebSocket connection failures from Wine/Proton to Ubisoft's servers on CachyOS or other NTSync-enabled kernels?

2. Is there a known Wine registry tweak or environment variable that forces HTTPS timeout handling to fall through rather than block?

3. Has anyone played Division 2 via Ubisoft Connect (not Steam) successfully on an NTSync kernel in early 2026?

Haven't seen anyone post about this specific issue, so figured I'd share how I resolved it.

I'm using linux mint cinnamon. When launching the game, I'd get a black screen that was stuck. I'd use Alt+tab to get back to steam window, and I'd notice that while the game was not focused, it was playing and not frozen. But when I'd tab back to the game, it would be frozen again, not allowing me to get past the initial settings.

THE FIX

Strange as it was, simply choosing any other window (I chose calculator), right clicking the title bar and setting to "always on top", allowed me to focus the game and not have it be frozen.

I dragged the calculator to the bottom corner so it was practically off-screen, and I was able to continue the game. From there, I personally chose to switch to a windowed game so that I won't need to do the "always on top" thing every time I decide to play.

Before trying this, I had tried launch options such as -windowed, -window-mode windowed, as well as trying several different proton versions, but to no avail.

Hopefully this will help someone else who is experiencing the same issue.

Trying to perform a fresh install of Fedora KDE Plasma on a dedicated NVMe drive for gaming (Steam/Discord). Using Fedora Media Writer to create the bootable USB.

Hardware:

• Motherboard: MSI MPG Z390 GAMING PRO CARBON AC
• CPU: Intel Core i7-8700K
• GPU: NVIDIA GeForce RTX 2070 (ASUS ROG STRIX)
• RAM: 32GB 2666MHz
• Storage: Samsung 500GB NVMe

The Issue: I cannot get the Live USB to boot. I initially hit an SBAT Security Violation

1. I reach the GRUB menu.
2. Selecting "Start Fedora-KDE-Live" immediately triggers: error: ../../grub-core/kern/mm.c:552: out of memory. Press any key to continue...
3. Pressing a key leads to a Kernel Panic: VFS: Unable to mount root fs on unknown-block(0,0)

What I’ve Tried So Far:

• BIOS Settings: Secure Boot Disabled, UEFI Mode only (CSM off), Integrated Graphics Disabled (PEG primary), Fast Boot Off.
• USB Variables: Tried different USB ports (Front panel vs. Rear Black USB 2.0 ports).
• Imaging Tools: Tried Fedora Media Writer and Rufus.
• GRUB Parameters (Edit Mode): * Added nomodeset (No change).
  • Added memmap=8M$0x1000 (Resulted in Kernel Panic).
  • Added vga=standard video=efifb:off (No change).

I know I have done this before with no issue here but thought I would really try to see if I could setup this to see if gaming could be something I could try but I'm getting hung up here before I can get to installing some games on Linux. Any help would be greatly appreciated. Thank you.

Hi all! I'm a Linux newbie. I found a guide (link:https://linuxvox.com/blog/fortnite-for-linux/) that explains how to install Fortnite, but the general consensus on Reddit seems to be that it won't work due to EAC/BattlEye.

Is there any truth to this guide, or is it just clickbait? I'd love to get a definitive answer before I dive in.

Simply put, my Resident Evil Requiem on Linux has these bright white flakes. I've already tried downgrading the card driver to 580, I've tried using startup parameters, I'm also experiencing some stuttering, so for now I'm playing the game in dual boot, but I'd like to be able to play it on Linux. But hey, that's a user and Linux problem.

OS: Cachy OS

PROTON: Cachy or Ge same bug.

GPU: RTX 3090

CPU: Intel(R) Core(TM) i5-10400F CPU @ 2.90GHz

I have downloaded Wine on my PC, and I have launched the command "wine path/to/.exe".

I had an error: "wine: could not load kernel32.dll, status c0000135", that specific .exe can be runned with Wine, I have done it some days ago on Garuda Linux (I have changed OS, now I use MX), so what should I do?
