升级到 13.04 后显示屏空白

我刚刚将 Ubuntu 升级到 13.04,登录 KDE 等离子工作区后,我无法更改任何显示器显示。这涉及将屏幕分辨率设置为大约 800x640(我通常使用 1600x1200),并且无法像往常一样添加第二台显示器。

我能做些什么来解决这个问题?我显然无法工作,也无法升级其他任何东西:

$ sudo apt-get upgrade

The following packages have been kept back:

你有 ?

KDE 有两个用于显示/监视器配置的模块:

年龄较大的:

:~$ 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.

Homepage: http://www.kde.org/

新的那一个:

:~$ 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.

Homepage: https://projects.kde.org/projects/playground/base/kscreen

您是否安装了其中的一个?

KDE 是否检测模块?

要列出可用的 KDE 控制模块类型(konsole):

kcmshell4 --list

这是:

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

A tool to start single KDE control modules

...

Options:
  --list                    List all possible modules

新模块:

kcm_kscreen - 管理和配置监视器和显示器

旧模块:

randr - 调整显示大小和旋转

您可以尝试从控制台启动它们:

kcmshell4 randr

或者

kcmshell4 kscreen

它们正在启动吗或者您是否收到错误消息。

如果它们都安装并检测到正确,KDE 系统设置应该会显示选项。
