Bug ID: 321699
Summary: System Settings crashes on primary display change
Classification: Unclassified
Product: systemsettings
Version: 1.0
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general
Assignee: unassigned-bugs at kde.org
Reporter: aleksi.uotila at gmail.com
Application: systemsettings (1.0)
KDE Platform Version: 4.10.3
Qt Version: 4.8.4
Operating System: Linux 3.8.0-23-generic x86_64
Distribution: Ubuntu 13.04
-- Information about the crash:
- What I was doing when the application crashed:
Before I changed my display port cable on primary display from normal display
port cable to a dvi cable with display port adapter (on computer end the same
port being used - on monitor end changed from display port to dvi). I also have
another display with DVI - DVI connection. This another monitor was secondary
display before the change but it got changed to primary I guess when I
unplugged the display port cable.
I didn't reboot the machine in between the cable change and this system
settings crash.
System settings app crashes when Apply is pressed on monitor settings (primary
monitor change on monitor settings before Apply).
The settings app crashes probably because xrandr is unable to switch the
primary too:
$ xrandr --output DisplayPort-0 --primary --right-of DVI-0
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 21 (RRSetCrtcConfig)
Serial number of failed request: 27
Current serial number in output stream: 27
$ xrandr --output DisplayPort-0 --primary
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 21 (RRSetCrtcConfig)
Serial number of failed request: 27
Current serial number in output stream: 27
$ xrandr --output D
DisplayPort-0 DVI-0
$ xrandr --output DVI-0 --left-of DisplayPort-0
$
The crash can be reproduced every time.
