Description d.aurora.y.linux 2025-07-31 03:47:39 UTC 
### 📝 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.
