Hello,

recently I updated my Fedora from 18 to 19, both running with KDE 4.10.4, but Fedora 19 now uses kscreen by default. Today I wanted to use an external monitor via VGA, but the second one (VGA) wasn't recognized by kscreen, so it looked like this: http://wstaw.org/m/2013/07/11/plasma-desktopcr1315.png

The output of kscreen-console, without external monitor is the following:

Code: Select all

$ kscreen-console

Unfortunately I forgot to save the output of kscreen-console with both monitors but the VGA-section it was something like:

Code: Select all

Id:  84
Name:  "VGA-0"
Type:  "Unknown"
Connected:  true
Enabled: false


But how can I enable the VGA port?
Thanks in advance!

additional info that maybe useful

- in earlier versions did the 2nd vga monitor display?
- gpu and drivers installed ?

Code: Select all

glxinfo |grep OpenGL

moved to Kwin forum

Yes, in earlier version it always worked out of the box.

Code: Select all

$ glxinfo |grep OpenGL

What does the "xrandr" command report for your VGA connector?

It works now! The KScreen-Service was not started, this was the whole problem.
Nevertheless maybe there should be a warning displayed when using KSreen and the service is not running? Otherwise it's hard to figure out.

Indeed, that is rather unusual - it should be running by default. I would suggest filing a bug against KScreen in this case, as the various KScreen tools should prompt to start the KScreen service if necessary.

You could try forcing the DisplayPort screen to be enabled directly through xrandr.

Code: Select all

xrandr --output DisplayPort-0 --auto
