I just upgraded my Ubuntu to 13.04 and after logging in my KDE plasma workspace I cannot change any monitor Display. It involves having the screen resolution at about 800x640 (I usually use 1600x1200) and not being able to add a 2nd monitor as usual.

enter image description here

Is there anything I can do to solve it? I clearly cannot work and cannot upgrade anything else:

$ sudo apt-get upgrade
Reading package lists... Done
Building dependency tree       
Reading state information... Done
The following packages have been kept back:
0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.

System information:

$ cat /etc/*ease
VERSION="13.04, Raring Ringtail"

Did you tried to install the driver of your graphic card ? – ttoine Jul 25 '13 at 13:40
Any reason for the downvote? Or is it just some range? – fedorqui Aug 21 at 15:25

Do you have ?

The KDE have two modules for the display/monitor configuration:

The older:

:~$ apt-cache show kde-workspace-randr
Package: kde-workspace-randr
Priority: optional
Section: universe/kde
Description-en: randr tools from kde-workspace
 Screen resize and rotate tools from KDE Workspace.


The new one:

:~$ apt-cache show kscreen
Package: kscreen
Priority: extra
Section: universe/kde
Description-en: KDE monitor hotplug and screen handling
 The KDE multiple monitor support is trying be as smart as possible
 adapting the behavior of it to each use case making the configuration
 of monitors as simple as plugging them to your computer.
 This package contains the modules and plugins for monitor hotplut and
 automatic screen handling.


Do you have one of those installed ?

Is the KDE detecting the modules ?

To list available KDE control modules type (konsole):

kcmshell4 --list

It is:

:~$ kcmshell4 --help
Usage: kcmshell4 [Qt-options] [KDE-options] [options] module 

A tool to start single KDE control modules


  --list                    List all possible modules

The new module:

kcm_kscreen - Manage and configure monitors and displays

The Old module:

randr - Resize and Rotate your display

You could try to launch them from the konsole:

kcmshell4 randr


kcmshell4 kscreen

Are they launching or do you get an error message.

If they are both installed and detected right the KDE system settings should show the options.

I have the new one, kcm_kscreen. I performed an apt-get update few days ago and must have been included in it, as now I can work with proper resolution and 2 monitors. I will give bounty as it was very helpful. --Also, to make the answer even better, I would suggest to add how to install each package. – fedorqui Jul 29 '13 at 9:01
