升级到 ubuntu 14.04 后,我遇到了多个问题。所有问题都与桌面界面有关。
升级后,我无法更改壁纸。首先,wallch(一个自动更改壁纸的程序)开始变得无响应。我用它来设置壁纸,但由于它无响应,我卸载了它。然后我尝试从“外观设置”更改壁纸,但没有成功。我还尝试了“设置为壁纸”选项,当我们右键单击图像文件(我们称之为 imgA)时,我们会看到这个选项,但仍然没有成功。然后我在 dconf-editor 中检查了桌面背景的值,它显示了 imgA 文件的值路径,但显示的背景是完全不同的图像。
我也尝试从 synaptic 重新安装 unity 和 nautilus 包,但问题仍然存在。
我开始面临的另一个问题是,当我从窗口栏最小化窗口时,Unity 会在我最小化所有打开的窗口中的最后一个窗口时挂起,并且只有当我按下“Alt”时才会做出响应
我最近安装了 playonlinux,并在全屏模式下玩了几款游戏。当我退出任何游戏时,桌面背景都会全黑,我必须注销并再次登录才能恢复背景。
我假设上述三个问题以某种方式相互关联。
我正在使用带有英特尔显卡的戴尔笔记本电脑。
如果我需要更多信息,请告知我。

正如下面评论所建议的,我从终端打开了 unity-control-center。以下是输出:
(unity-control-center:15831): Gtk-CRITICAL **: gtk_radio_button_set_group: assertion '!g_slist_find (group, radio_button)' failed
(unity-control-center:15831): Gtk-CRITICAL **: gtk_radio_button_set_group: assertion '!g_slist_find (group, radio_button)' failed

.... 其中许多输出消息
然后当我关闭它时..我得到了以下两行
(unity-control-center:15831): Gtk-CRITICAL **: gtk_builder_get_object: assertion 'GTK_IS_BUILDER (builder)' failed
(unity-control-center:15831): Gtk-CRITICAL **: gtk_icon_view_get_selected_items: assertion 'GTK_IS_ICON_VIEW (icon_view)' failed

我不确定如何,但在启用桌面图标(使用ubuntu-tweak-tool
)后,一切都恢复正常。请参阅此答案:askubuntu.com/a/284076/27577
