GE-Proton 11-4 and 11-5: The Controller Fixup Release That Finally Brings DualSense Haptics to Linux

After six years, Linux and Steam Deck gamers can finally use their PlayStation 5 DualSense controller with full haptic feedback, built-in speaker audio, and reliable hotplug support — thanks to GE-Proton 11-4. Released August 11, 2026, this community-maintained Proton build from GloriousEggroll is the biggest controller-focused update the fork has ever shipped . But it came with a catch that forced an emergency hotfix the same day.

What GE-Proton 11-4 delivers

Dubbed the "Controller fixup" release, GE-Proton 11-4 finalizes support for the DualSense, DualSense Edge, and DualShock 4 on Linux . The update adds three new environment-variable-controlled modes for using these controllers outside of Steam Input :

• DS4 Spoof — makes newer DualSense and DualSense Edge controllers appear as a standard DS4 controller, useful for games that only recognize the older DualShock 4, such as Assassin's Creed Odyssey, Origins, and 3 Remastered
• XInput conversion — maps the controller as an Xbox-style device for games that don't support native PlayStation controllers at all
• Steam Input fallback — falls back to Steam Input processing when needed for compatibility

Beyond controllers: Wine, graphics, and game-specific fixes

The update also rebased the Wine base and GE patch sets, updated DXVK, DXVK-NVAPI, VKD3D, and VKD3D-Proton, and refreshed the Wine-Wayland/EM-11 patch set with fullscreen, focus, scaling, pointer, IME, colorspace, and deadlock fixes .

Game-specific changes include:

• Street Fighter 6 — fixed a Media Foundation source-reader race condition that broke cutscenes unless debug logging was enabled
• Star Citizen — fixed an unsupported-OS message-box crash and its condition check
• Monster Hunter Wilds — improved controller handling

The release also stopped automatically showing DXVK shader compiler text unless explicitly requested through the DXVK_HUD environment variable, and included general improvements to ARM64 support, audio, and video playback .

The 11-5 hotfix: why you must upgrade

GE-Proton 11-5 landed only hours after 11-4 as an urgent patch . The 11-4 build had introduced a critical Easy Anti-Cheat loading regression that broke multiplayer titles relying on kernel-level anti-cheat middleware — including Monster Hunter Wilds and Hunt: Showdown .

GloriousEggroll rebased 11-5 on Valve's upstream Proton 11 branch to restore that compatibility . Within hours of release, the hotfix had accumulated close to 4,000 downloads on x86_64 .

Bottom line

GE-Proton 11-4 is a landmark release for Linux gaming, finally delivering the PlayStation controller experience that Sony's hardware has deserved since 2020. If you've just installed 11-4, however, upgrade to 11-5 immediately to avoid anti-cheat breakage in multiplayer games. The 11-5 build preserves all the controller improvements while restoring compatibility where it matters most.
