# Double Login Prompt Issue with Hyprland and SDDM

## Issue Summary
Users experience two consecutive login prompts when logging into Omarchy Linux with Hyprland and SDDM:
1. Standard SDDM login screen
2. Additional login prompt from uwsm (Universal Wayland Session Manager)

**Root Cause**: The Omarchy update system creates a `hyprland-uwsm.desktop` file that causes SDDM to prefer uwsm-managed sessions, creating nested session management.

## Environment
- **OS**: Omarchy Linux
- **Display Manager**: SDDM
- **Window Manager**: Hyprland
- **Session Manager**: uwsm (Universal Wayland Session Manager)
- **Update System**: Omarchy built-in update mechanism

## Steps to Reproduce
1. Boot system to SDDM login screen
2. Enter valid credentials and log in
3. Observe second login prompt appearing after initial login
4. Must log in again to access Hyprland session

## Expected Behavior
After logging in via SDDM, Hyprland session should start directly without additional login prompts.

## Actual Behavior
Two login prompts are required:
1. SDDM login screen (normal)
2. uwsm-managed session login prompt (unexpected)

## Root Cause Analysis

### Timeline of Events:
1. **September 14, 2025**: uwsm package installed as part of system setup
2. **October 3, 2025**: Omarchy update system created `hyprland-uwsm.desktop` file
3. **October 3, 2025**: SDDM began preferring uwsm-managed session, causing double login

### Technical Details:
The issue stems from having two Hyprland desktop entries:
- `/usr/share/wayland-sessions/hyprland.desktop` (standard)
- `/usr/share/wayland-sessions/hyprland-uwsm.desktop` (uwsm-managed - created by Omarchy)

**Key Evidence**:
- The `hyprland-uwsm.desktop` file was **NOT** part of the original uwsm package
- File creation date: October 3, 2025 at 06:02:19
- Omarchy update system found at `/home/nick/.local/share/omarchy/bin/omarchy-update`
- Omarchy has uwsm configuration at `/home/nick/.local/share/omarchy/config/uwsm/`
- No pacman hooks or manual creation involved

SDDM is selecting the uwsm-managed session, which creates a nested session management scenario.

Oct 08 07:42:12 omarchy sddm[900]: Session "/usr/share/wayland-sessions/hyprland-uwsm.desktop" selected, command: "uwsm start -- hyprland.desktop" for VT 1

```

## Proposed Solutions

### Solution 1: Remove uwsm-managed desktop file (Recommended)
```bash
# Remove the problematic desktop file created by Omarchy
sudo rm /usr/share/wayland-sessions/hyprland-uwsm.desktop
```

### Solution 2: Disable uwsm-managed session (Alternative)
```bash
# Rename to disable instead of removing
sudo mv /usr/share/wayland-sessions/hyprland-uwsm.desktop /usr/share/wayland-sessions/hyprland-uwsm.desktop.disabled
```

### Solution 3: Configure SDDM to prefer standard session
Create `/etc/sddm.conf`:
```ini
[General]
SessionCommand=/usr/share/sddm/scripts/wayland-session
SessionDir=/usr/share/wayland-sessions
Session=hyprland.desktop
```

### Solution 4: Check uwsm configuration
```bash
uwsm select
```

## Omarchy Update System Investigation

### Files Found:
- **Update Script**: `/home/nick/.local/share/omarchy/bin/omarchy-update`
- **uwsm Config**: `/home/nick/.local/share/omarchy/config/uwsm/`
- **Migration System**: `/home/nick/.local/share/omarchy/migrations/` (100+ migration scripts)

### Evidence:
- Omarchy has built-in uwsm integration
- Migration system runs during updates
- Desktop file creation timestamp matches user's update activity
- No manual intervention or pacman hooks involved

### Repository Investigation:
- **Cloned Omarchy repository**: No script found that creates `hyprland-uwsm.desktop`
- **uwsm integration**: Found in `omarchy/config/uwsm/` with environment setup
- **Migration system**: `omarchy/bin/omarchy-migrate` runs scripts during updates
- **uwsm usage**: Found in `omarchy/install/login/plymouth.sh` and migration scripts
- **Conclusion**: Desktop file creation is likely from a **dynamic migration script** or **uwsm package behavior** not in the main repository

## Impact
- **Severity**: Medium
- **Frequency**: Always (100% reproducible)
- **User Experience**: Significantly degraded due to double authentication requirement

## Additional Context
This issue is specifically related to the **Omarchy update system** creating desktop files that conflict with SDDM's session management. The Omarchy update system appears to have a migration or configuration script that creates the `hyprland-uwsm.desktop` file during updates, causing SDDM to prefer uwsm-managed sessions over standard Hyprland sessions.

### Investigation Notes:
- User only used normal applications (Cursor, web browsing, music) on October 3rd
- No manual system configuration or package installation
- Omarchy update system has extensive migration scripts (100+ files)
- uwsm integration is built into Omarchy's configuration system

## Labels
- `bug`
- `hyprland`
- `sddm`
- `session-management`
- `user-experience`
- `omarchy-update-system`
- `uwsm-integration`

## Priority
Medium - Affects user experience but has workarounds available. Issue is caused by Omarchy's update system, not user error.
