Testers wanted: AppImage, deb and rpm on your distribution (v0.2.9 and later)

BlizzNux · 2026-10-03T16:09:50+00:00

The launcher's downloads changed a lot today. The AppImage is now built for older distributions, and the deb and rpm no longer need a umu-launcher package from your distribution: when none is installed, the launcher downloads umu's official release by itself. We have only tested start-up on Ubuntu 22.04 and the full flow on CachyOS, so we need your help. If you try BlizzNux Launcher v0.2.9 or newer, please reply with: Your distribution and version (for example Ubuntu 24.04, Fedora 44, Debian 13, Mint 22, Bazzite). Which download you used: AppImage, deb or rpm. Whether the launcher starts. Whether "Install Battle.net" gets you to the Battle.net login screen. If something fails: what you saw. For the AppImage, start it from a terminal and paste the last lines it prints. Arch and CachyOS users are welcome to report too. Not affiliated with Blizzard Entertainment.

Everything looks normal, to me at least. It just never progresses past this point. Battle.Net never opens.

Thanks a lot for the report and the log, Voo. They pointed straight at the bug: on computers without hybrid NVIDIA graphics, the launcher stopped silently right before starting Proton, so setup never got past "Setting up Proton".

The latest release, v0.2.38, fixes it: https://github.com/BlizzNux/launcher/releases/tag/v0.2.38

Download the new AppImage or rpm and start it again. Proton is already downloaded, so it should go straight to the Battle.net installer. Let us know how it goes!

satertek

Expectations were low because of my OS and iGPU, but the only workaround I had to use was PROTON_USE_WOW64=1 so that I didn't have to mess with finding the 32bit mesa drivers. Performance is obviously limited by the iGPU, but everything works as far as logging in, downloading WoW Forever, and loading up the game!

Thanks satertek this is a really useful report: an immutable Fedora 44 with only an Intel iGPU is about as hard a setup as it gets, and it's good to hear everything worked.

Your workaround is now built in. Today's release, v0.2.43 (out at 2 PM Eastern), adds Settings → Labs → Wine WoW64 mode, which sets PROTON_USE_WOW64=1 for you, so you won't need the variable anymore. Reports sent with it on are marked "Modified" and kept off the public Compatibility board while WoW64 mode is experimental.

If you link the launcher to your BlizzNux account (Settings → Account), your runs will show up in the reports and help me see how WoW64 mode does on other machines.

Karl

satertek small update: I went ahead and released early, so v0.2.43 is out now instead of at 2 PM. The launcher offers the update on its next start, or download it from https://github.com/BlizzNux/launcher/releases/tag/v0.2.43. Wine WoW64 mode is under Settings → Labs, and if you keep starting it with PROTON_USE_WOW64=1, that now counts as the same setting.

Karl
Will give it a shot, I did some more optimizations and got it running pretty well with decent power usage locked at 30 FPS. Most of these will be specific to my setup and WoW Forever, but might help someone else running something similar:

Proton & DXVK Environment Variables

PROTON_USE_WOW64=1 — Runs 32-bit Battle.net.exe over 64-bit Wine/Vulkan on pure 64-bit distros, preventing GPU process crashes (0xC0000005).
PROTON_USE_XALIA=0 — Disables the background controller-UI scanner, stopping 14,000+ Mono exceptions and constant window polling.
DXVK_CONFIG="dxvk.trackPipelineLifetime = True; dxvk.numCompilerThreads = 3; [Battle.net.exe]; d3d11.maxFrameRate = 15" — Frees unused Vulkan shader pipelines to save shared RAM/VRAM, caps shader compiler threads so they do not starve the main render thread on a 4-core CPU, and limits the launcher UI to 15 FPS.

WoW & Battle.net (Config.wtf / Battle.net.config)

Switched to DirectX 11: Set SET GxApi "D3D11" in Config.wtf to use DXVK instead of vkd3d-proton, reducing CPU/descriptor overhead and eliminating D3D12 driver stalls.
Auto-Closed Battle.net Launcher: Set "GameLaunchWindowBehavior": "2" in Battle.net.config so the launcher exits on game start, reclaiming 50–80% of a CPU core and ₅₀₀ MB RAM.

Intel CPU & Power Management (intel_pstate / RAPL)

Tuned intel_pstate for Shared Package Power: Set min_perf_pct to 10, governor to powersave, EPP to balance_power, and scaling_max_freq to 2800 MHz. CPU power dropped from _9W to 2.7W, preventing PL4 peak current throttling and freeing thermal/power headroom for the iGPU.
Removed 11.5W Adaptive Power Throttling: Stopped thermald, disabled the MMIO RAPL override (enabled=0), set MSR RAPL PL1 to 18W, and set /sys/firmware/acpi/platform_profile to quiet. This prevents premature 11.5W clamping at 55–65°C die temps and drops fan speeds by ₃,000 RPM.

Intel Iris Xe GPU & xe Kernel Driver

Capped iGPU Frequency to Sweet Spot: Set min_freq to 350 MHz and max_freq to 850 MHz in /sys/class/drm/card0/device/tile0/gt0/freq0/. Keeps GPU load at 70–80% for a 30 FPS target, draws only 3.8W, and allows ₂₀% per-frame deep sleep (RC6).
Locked Runtime Power Management: Set /sys/class/drm/card0/device/power/control to on, stopping GuC SLPC firmware from resetting max_freq down to 600 MHz every 60 seconds.
Extended rcs Engine Timeouts: Set preempt_timeout_us to 2000000 (2s), job_timeout_ms to 10000 (10s), and dev.xe.observation_paranoid=0, eliminating engine_class=rcs GPU resets during heavy shader compilation.

Karl

satertek Thanks, this is great detail. A few notes for anyone copying it:

PROTON_USE_WOW64=1 is now Settings → Labs → Wine WoW64 mode in v0.2.43, and a hand-set one counts the same.
The launcher keeps your own DXVK_CONFIG as is, so those DXVK settings work alongside it.
Closing Battle.net when a game starts is also an option in Battle.net's own settings (When I launch a game → Exit Battle.net completely).
The CPU and iGPU power settings are specific to your laptop, and some (stopping thermald, raising power limits, longer GPU reset timeouts) can cause heat or stability problems elsewhere, so anyone trying them should go carefully.

Two of your tweaks are going into Labs as switches, so nobody has to set them by hand:

Turn off Xalia (PROTON_USE_XALIA=0), the controller helper behind those Mono exceptions in your log.
Cap the Battle.net window at 15 FPS, for less power use while it sits open. Games aren't affected.

Would you like me to push these out as soon as they're ready, or are you fine waiting for the next regular Sunday release?

Karl

satertek Both are out in v0.2.44: Xalia is now off by default (Settings has a "Controller navigation in Battle.net's window" switch if you ever want it back), and Settings → Labs → Cap the Battle.net window at 15 FPS is there. You can drop PROTON_USE_XALIA=0 and the [Battle.net.exe] frame cap from your own DXVK_CONFIG.
