[PSA][Linux] Hunt: Showdown EAC kicks (0x4000a / 0x7111) — Confirmed workaround
There's a known regression in Proton Experimental causing Easy Anti-Cheat to flag hunt.exe as an untrusted system file, resulting in players being kicked from matches.
Affected version: Proton Experimental (experimental-11.0-20261014)
Workaround: Switch Hunt: Showdown 1896 to Proton 11.0-2 (Stable) or GE-Proton (latest / 11-11) under Steam → Properties → Compatibility.
Proton 11.0-2 tested and confirmed working. GE-Proton also reported working by other players. No reinstall or Proton prefix reset required.
Installing GE-Proton (latest)
GE-Proton isn't included in Steam by default. For native Steam on Linux (x86_64), run:
(
set -e
url=$(curl -fsSL -o /dev/null -w '%{url_effective}' \
https://github.com/GloriousEggroll/proton-ge-custom/releases/latest)
version="${url##*/}"
base="https://github.com/GloriousEggroll/proton-ge-custom/releases/download/$version"
cd "$(mktemp -d)"
curl -fLO "$base/${version}-x86_64.tar.gz"
curl -fLO "$base/${version}-x86_64.sha512sum"
sha512sum -c "${version}-x86_64.sha512sum"
mkdir -p "$HOME/.steam/steam/compatibilitytools.d"
tar -xf "${version}-x86_64.tar.gz" \
-C "$HOME/.steam/steam/compatibilitytools.d/"
)
Important: Fully exit Steam using Steam → Exit (top-left menu), not just by closing its window. Restart Steam, then select the installed GE-Proton version under Hunt → Properties → Compatibility.
The command downloads the latest GE-Proton release whenever you run it. Updates are not automatic.
Flatpak Steam users: Official installation instructions.
---
The underlying VKD3D-Proton bug has already been identified and fixed upstream, but the fix may not yet be available in Proton Experimental.
Bug report: vkd3d-proton#3348
Hope this saves someone some troubleshooting. Good hunting!

Warning to Linux/Steamdeck Maplers
There are a group of us that recently got a perma-ban for "hacking or unauthorized use of third-party programs"
I hopped off my desktop and went to couch game on steamdeck while watching TNF and about 1 minute into starting Round 1 KPQ I was disconnected and met with this message.
No botting, no hacking, no RMT of any kind. My main is level 41 and my alt is 23..I play a normal-ish 4-6 hours a day when not afking/store.
Have tickets opened and am reaching out to Community Managers on discord to try and get some movement but also I wanted to let anyone else know...since reddit is where I got the idea to game on steamdeck.
Only change required on Steamdeck is to use GE Proton 11.0-3 as the compatibility tool.
github.com/gloriouseggroll/proton-ge-custom/relea…
Update as of 10PM EST 10/24/2026:
A handful of people have reported getting unbanned, both windows and linux users who were receiving the same message. Unfortunately I havent yet. They said they were unbanned and their ticket still hadnt been responded too. So theyre probably just flooded with tickets
Update as of 10AM EST 10/25/2026:
My ban/ticket still have no response. As of now people are reporting NEW bans for SteamDeck/Linux users. Play at your own risk

[Mass Effect Legendary Edition] How can I run the 1st game on my openSUSE Tumbleweed?
Hello.
I installed a repack of MELE from FitGirl on my Linux laptop. The installations went fine without any errors (both the game files and provided DirectX) through Proton GE 11-10 (GloriousEggroll/proton-ge-custom), but I can't launch neither the game nor the provided launcher (the launcher itself works fine, but it doesn't launch the selected game).
Has anyone encountered this issue? Can I somehow fix it?

GE-Proton11-10 Released · GloriousEggroll/proton-ge-custom
Component Updates
- Wine: Valve bleeding-edge 2026-10-16. This brings upstream syscall emulation through Syscall User Dispatch and native-syscall handling for EAC (EOS) launchers. Also included: Xalia now shuts down cleanly, fewer spurious X11 mouse movement events, a Witcher 3 controller rescan fix, and a ddraw fix for paletted primary surfaces.
- Wine: PROTON_LIMIT_ADDRESS_SPACE and its address-space limits for Reverse: 1999 and Blue Protocol: Star Resonance were removed upstream.
- DXVK: v3.1.1-134. Includes D3D9 texture, StretchRect and device-reset fixes, D3D8 CopyRects rework, a workaround for an EA anti-cheat code-signing crash, shader cache fixes, and zero-initialized shader scratch memory for Call of Duty: Ghosts.
- D7VK: rebased onto DXVK v3.1.1.
- VKD3D-Proton: fixes synchronization around queued transfer operations.
- FEX: FEX-2610-30.
Controllers
- The automatic PlayStation controller XInput fallback no longer rescans every HID device each time a game polls an empty controller slot. Since GE-Proton11-8 this caused large slowdowns, even with no controller connected:
- Path of Exile ran at ~50 FPS instead of 200+ (#862).
- Le Mans Ultimate slow-motion physics with a Moza wheel (#777).
- Story of Seasons: Friends of Mineral Town lost FPS with PROTON_PREFER_SDL (#850).
- Setting PROTON_SONY_AUTO_XINPUT=0 confirmed this was the cause in #862; the fix itself has not been confirmed in-game yet.
- Sackboy: A Big Adventure and Rune Factory 4 Special now default to PROTON_SONY_AUTO_XINPUT=0. This fixes the DualSense being assigned to player two in Sackboy and scrambled DS4 input in Rune Factory (#843). The variable was confirmed by two users.
- Bluetooth DualShock 4 and DualSense rumble now works through the XInput fallback, and input no longer stops after the first rumble (#853, thanks @ilyasbounoua). Native hidraw games on Bluetooth keep the extended controller reports (gyro and touchpad).
- PROTON_SONY_HIDRAW_XINPUT, PROTON_SONY_AUTO_XINPUT, PROTON_DUALSENSE_HAPTICS_PREFER_NON_EVENT and PROTON_DEATH_STRANDING_CONTROLLER_EFFECTS now reach the HID bus driver; previously the driver ignored them.
Wayland and Windowing
- GNOME: fixed games and launchers closing when a window that owns a popup is destroyed (mutter: "destroyed popup not top most popup"). This affected AION 2 and Battle.net auto-login with PROTON_ENABLE_WAYLAND=1 (#834). Not yet confirmed on GNOME.
Video Playback
- MonoGame games no longer stall or crash when a song is played again, for example Picross for a Cause (#839, thanks @Petru101).
Rendering and HDR
- KDE Plasma: HDR detection now uses KWin's per-monitor HDR state. HDR monitors are detected even when SDR brightness is set to the HDR reference level. Other compositors keep the existing detection (#838).
Other Changes
- Arknights: Endfield: added the ACE anti-cheat driver fixes from dwproton (#847):
- DriverEntry is called with a kernel-mode return address.
- ntoskrnl fixes: MmCopyMemory, ServiceKeyName, MDL section views and PsGetContextThread.
- A stub lsass.exe (SamSs) service is added and started.
- This matches dwproton. The remaining ACE bugcheck 0x65636154 is still unresolved there too.
- Star Citizen: loads the game's bundled AMD AGS library again, as GE-Proton11-6 did. This should avoid the EAC "Untrusted system file" violation and error 30033 (#858). Not yet confirmed in-game.
- Faster shared SRW lock releases. Lock-heavy games spend less time in ntdll; Microsoft Flight Simulator 2024 went from 24.5% to 19.1% (#844, thanks @smatkovi).
- Build: clang/libc++ and llvm-libc build fixes (#835, thanks @FireBurn).

How to play StarCraft or SC II on Linux
Install GE-Proton11-9, umu-launcher and gamescope. Then run the following command:
WINEPREFIX=/home/user/.local/share/Steam/steamapps/compatdata/2337950952/pfx PROTONPATH="/home/user/.local/share/Steam/compatibilitytools.d/GE-Proton11-9/" PROTON_ENABLE_WAYLAND=1 UMU_NO_RUNTIME=1 UMU_RUNTIME_UPDATE=0 gamescope -h 1080 -H 1080 -r 120 -f -- umu-run "Z:\home\user\games\StarCraft II\StarCraft II.exe"
Before running the command, you will need to change WINEPREFIX to point to your Wine prefix. If you don't know what that is, change it to point to a new folder in your home directory. Once you set WINEPREFIX, use the same one each time you launch Battle.net, for example "WINEPREFIX=/home/user/games/bnet" would create and use a Wine prefix at /home/user/games/bnet.
Change PROTONPATH to point to wherever you extracted GE-Proton11-9. If you use the path provided (after changing "user" to your username), GE-Proton11-9 will also be available to use in Steam.
Change umu-run "Z:\home\user..." to point to where you have StarCraft II installed. If you haven't installed StarCraft II yet, point it to Battle.net.exe instead.
If you aren't using Wayland, remove "PROTON_ENABLE_WAYLAND=1". If you don't know what Wayland is, try launching the game with "PROTON_ENABLE_WAYLAND=1", and if the game doesn't start, remove it.
This example is for a screen with 1920x1080 resolution at 120Hz. Read the gamescope documentation for info on how to configure it for other resolutions and refresh rates. (Run "gamescope --help" to view documentation.)
