@ -63,7 +63,6 @@ For Vulkan, you also need the driver for your GPU:
- **Linux 6.7 or later** -- required for explicit sync (needed for Nvidia GPUs).
- **Xwayland** -- required for running X11 applications.
- **PipeWire** -- required for screen sharing.
- **logind** (part of systemd) -- required when running Jay from a virtual terminal or display manager.

### SCHED_RR and config.so
`SCHED_RR` and `config.so` are mutually exclusive: running untrusted code at
real-time priority would be a security risk. Jay enforces this as follows:
- If `config.so` exists in the config directory, Jay skips the `SCHED_RR`
elevation (elevated Vulkan queues are still created).
- If Jay has already elevated to `SCHED_RR`, it refuses to load `config.so`.
### SCHED_RR
You can also skip `SCHED_RR` explicitly by setting `JAY_NO_REALTIME=1`:

This still allows elevated Vulkan queues and does not affect `config.so`
loading.
The mutual exclusion can be overridden at compile time by building Jay with
`JAY_ALLOW_REALTIME_CONFIG_SO=1`.
This still allows elevated Vulkan queues.
## Recommended Applications
@ -156,7 +144,6 @@ The following applications work well with Jay:
- **[Alacritty](https://alacritty.org/)** -- the default terminal emulator in the built-in configuration.
- **[bemenu](https://github.com/Cloudef/bemenu)** -- the default application launcher in the built-in configuration.
- **[xdg-desktop-portal-gtk4](https://github.com/mahkoh/xdg-desktop-portal-gtk4)** -- a file-picker portal with thumbnail support. Used automatically when installed.
- **[wl-tray-bridge](https://github.com/mahkoh/wl-tray-bridge)** -- shows D-Bus StatusNotifierItem applications as tray icons.
- **[mako](https://github.com/emersion/mako)** -- a notification daemon. Launched automatically by the default configuration.
- **[window-to-tray](https://github.com/mahkoh/wl-proxy/tree/master/apps/window-to-tray)** -- run most Wayland applications as tray applications (e.g. `window-to-tray pavucontrol-qt`).
