### 📝 Bug Report: Black Screen After Switching to Auto-login Users (Wayland +
X11)
**System:**
* openSUSE Tumbleweed (latest updates as of July 2025)
* Tested under both **Wayland** and **X11** sessions
**Problem Description:**
When using two user accounts (e.g., `userA`(Auto-login user) and `userB`(normal
login user)), switching between users causes a black screen under the following
conditions:
1. Switching to **userB** has not issue.
2. Switching to **userA** will enter to blank screen, whether from userB to
userA, or from userA to userA.
➡️ **Result:** After entering **userA**'s password, the screen goes completely
black. The desktop environment does not load.
**temporary Recovery:**
* Pressing `Alt + Shift + F2` to input login password again will login.
**Workaround Found:**
* **Disabling auto-login** in System Settings prevents the issue entirely.
➡️ When both users manually log in through SDDM (no auto-login), the black
screen no longer occurs when switching users.
