Bug ID: 343608
Summary: Display Configuration detecting two monitors as a
single monitor
Product: systemsettings
Version: unspecified
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: unassigned-bugs at kde.org
Reporter: linuturk at onitato.com
My laptop is docked, and two DVI cables are plugged into the dock. Each cable
goes to a separate monitor. KDE is seeing this as a single large display. There
also seems to be issues related to booting and the login screen. The displays
don't always activate during the encryption password prompt or the login
screen.
Reproducible: Always
Steps to Reproduce:
1. Boot the computer.
2. Login without seeing anything.
3. Open Display Configuration and try to configure the monitors separately.
Actual Results:
Shown as one large display.
Expected Results:
Two separate inputs that are configurable.
