If NymVPN opens with a blank or empty window on Linux, the cause is almost always graphics related: either an NVIDIA graphics card interacting badly with the display backend, or a known issue with the AppImage build of the app. The fixes below cover both cases.
NVIDIA graphics on X11
该问题在大多数的情况下都可以检测到并且系统内部会自动处理。 However, if you are still encountering a blank screen, try launching the app with the following command:
GDK_BACKEND=x11 WEBKIT_DISABLE_DMABUF_RENDERER=1 nym-vpn-appNVIDIA graphics on Wayland
We have received some reports of similar blank screen issues when using Wayland with NVIDIA graphics. 和 X11 不同的是该问题并没有一个自带的的修复方案。 If you are using Wayland and experience a blank screen:
- Try switching to an X11 session as a temporary workaround.
- Or contact the NymVPN support team and let us know your system setup so we can help troubleshoot.
We are actively looking into better long-term support for Wayland and NVIDIA setups.
Blank screen with the AppImage version
Some users launching the AppImage version of the NymVPN client may encounter a blank window regardless of graphics card. If the following message appears in the app logs, this is the cause:
Could not create default EGL display: EGL_BAD_PARAMETER. Aborting...This is an upstream graphics compatibility issue related to how the AppImage was generated using Tauri. There is no fix available at this time; it is tracked on GitHub as Issue #2985.
Workaround: use an installation method that is not affected by the EGL error:
- Deb or AUR packages (if available for your distro)
- Flatpak package
Still seeing a blank screen?
Contact Nym Support with your distro, desktop environment, display server (X11 or Wayland), graphics card, installation method, and logs. 您可以参阅文章 NymVPN 的应用程序和守护进程日志在哪里？
