Title: Antigravity unusable on Pop!_OS 24.04 — multiple compounding issues prevent sign-in

Hi Antigravity team,

I’m reporting a chain of issues that together make Antigravity completely unusable on my system. I’m posting here because I cannot sign in to use the in-app feedback channel.

System

  • OS: Pop!_OS 24.04 LTS x86_64
  • Kernel: 6.18.7-76061807-generic
  • DE: GNOME 46.0 (Mutter / Wayland)
  • CPU: 12th Gen Intel i5-1245U
  • GPU: Intel Alder Lake-UP3 GT2 (Iris Xe)
  • Antigravity installed via the official APT repo (us-central1-apt.pkg.dev)
  • Default browser: Zen Browser (installed as Flatpak)

Issues encountered, in order

1. Icons render as text labels. In the chat panel during voice recording, icon components display the text strings “mic”, “square”, and “close” instead of rendering icons. This appears to be a Lucide/icon-font fallback failure. System fontconfig is healthy and fc-cache -fv did not help. Launching with --disable-gpu did not help.

2. MCP servers fail with “npx: executable file not

found in $PATH”. Node was installed via nvm (~/.nvm/versions/node/v24.13.0/bin/), which does not propagate to GUI processes. Worked around by symlinking node/npm/npx into /usr/local/bin/. Suggestion: Antigravity could resolve npx from a configured Node path or detect nvm installations.

3. Extensions Marketplace shows “Error while fetching extensions. Failed to fetch”. Open VSX is reachable from the same machine via curl (HTTP/2 200). Worked around by overriding extensions.gallery.serviceUrl to point to the VS Code Marketplace.

4. “Sign in to access Extensions Marketplace” button is unclickable. This is the current blocker. The button renders but does not respond to mouse clicks. I’ve tried:

  • Clearing ~/.config/Antigravity/Session Storage and Local Storage
  • Clearing Cache, GPUCache, and auth-tokens directories
  • Setting Firefox (native, non-Flatpak) as the default browser via xdg-settings
  • Confirming gnome-keyring and libsecret-1-0 are installed
  • Full uninstall and reinstall of the antigravity package

None of these resolved the unclickable button.

What I’m asking

  1. Is there a known issue with the sign-in flow on Pop!_OS 24.04 / GNOME 46 / Wayland?
  2. Is there a CLI-based authentication method I can use to bypass the broken UI button?
  3. Where are the renderer logs stored on Linux? I’d like to attach them.

Happy to provide additional logs, screenshots, or testing as needed.

Thanks,
Driss Nafii
