Image of my log screen showing the huge virtual keyboard
# Summary
After upgrading to Plasma 6.8 on CachyOS, the SDDM login screen always displays
a large virtual keyboard whenever the password field receives focus.
The issue occurs on a desktop system with no touchscreen, no tablet mode
support, and virtual keyboards disabled.
# System Information
- Distribution: CachyOS
- KDE Plasma: 6.8.0
- SDDM: 0.21.0-8
- Session: Plasma Wayland
- GPU: AMD Radeon RX 7900 XTX
- Monitor 1: 3840×2160 @ 120 Hz
- Monitor 2: 2560×1440 @ 60 Hz
- SDDM Theme: Breeze
# Steps to Reproduce
1. Connect two monitors.
2. Boot the system normally.
3. Wait for the SDDM login screen.
4. Click inside the password field.
# Expected Result
No virtual keyboard should appear because:
- Virtual Keyboard provider is set to "None".
- Virtual Keyboard policy is set to "Never".
- There is no touchscreen attached.
- Tablet mode is unavailable.
- This is a desktop PC with mouse and keyboard.
# Actual Result
A large virtual keyboard appears automatically as soon as the password field
gains focus.
Observed behavior:
- The keyboard occupies a large portion of the screen.
- The keyboard appears on the secondary monitor by default.
- If the password field on the primary monitor receives focus, the keyboard
moves to the primary monitor.
- If the keyboard is manually hidden and the password field is focused again,
it immediately reappears.
- The behavior only occurs on the SDDM login screen.
# Additional Diagnostics
## Virtual Keyboard Configuration
System Settings → Keyboard → Virtual Keyboard
Provider:
```text
None
```
Policy:
```text
Never
```
## Tablet Mode Status
KWin reports:
```text
org.kde.KWin.TabletModeManager
tabletMode = false
tabletModeAvailable = false
```
## Input Method Checks
IBus service is not running:
```bash
systemctl --user status ibus.service
```
returns:
```text
Unit ibus.service could not be found.
```
No IBus processes are running:
```bash
ps aux | grep ibus
```
returns only the grep process.
Environment variables:
```bash
echo $GTK_IM_MODULE
echo $QT_IM_MODULE
echo $XMODIFIERS
```
all return empty values.
## Touchscreen Detection
No touchscreen or tablet devices are present.
KWin reports:
```text
tabletModeAvailable = false
```
## SDDM Theme Investigation
The Breeze SDDM theme contains references to KWin virtual keyboard
functionality:
```qml
Keyboards.KWinVirtualKeyboard.forceActivate()
```
located in:
```text
/usr/share/sddm/themes/breeze/Main.qml
```
# Multi-Monitor Observation
This appears to be directly related to the presence of a second monitor.
## Reproducible Workaround
If the secondary monitor is powered off and the system is rebooted:
- SDDM behaves normally.
- No virtual keyboard appears.
- Login works as expected.
If the secondary monitor is connected:
- The virtual keyboard always appears when the password field gains focus.
This suggests a possible interaction between:
- SDDM Breeze theme
- KWin virtual keyboard
- Multi-monitor handling
- Plasma 6.8
# Regression
The issue started immediately after upgrading to Plasma 6.8.
The behavior was not observed prior to the upgrade.
# Hardware Configuration
```text
GPU: AMD Radeon RX 7900 XTX
Primary Monitor: 3840×2160 @ 120 Hz
Secondary Monitor: 2560×1440 @ 60 Hz
Session Type: Wayland
```
# Notes
This appears to be a login-screen issue only.
The desktop session itself works normally.
The issue is reproducible and disappears when the second monitor is
disconnected before booting.
