更新 1:

我试图打补丁,但这是一个问题,因为关于这个主题的信息非常有限。顺便说一下,我使用的是 Kubuntu 16.04 LTS。

出于某种原因,我认为应该安装要修补的软件包。该软件包是qtbase5-dev。安装此软件包并重新启动计算机后,图形发生了变化。

标题栏中的标题更大(字体更大),插件中的字体也更大(如时间和日期、wifi 选项等)。Chromium 现在要求我将其设为默认浏览器(尽管我的帐户仍处于登录状态)。在终端(konsole)中,光标在字母前 2 或 3 个空格。在 kate 中,某些单词无法正确显示,并且选项卡的水平间距已更改(幸运的是,由于某种 ascii 艺术,我注意到了)。

我立即卸载该软件包并重新启动,但没有成功。

更新 1:

我还注意到,在登录屏幕上,背景图像似乎被放大了,当我正确输入密码并按回车键时,图像将正常呈现(不缩放)并启动系统,但会出现我遇到的所有问题。此外,现在我无法使用功能键更改亮度,节能窗口中的亮度变灰(禁用)。

更新 2:

到目前为止,我一直在进一步探索这种情况,亮度问题似乎是由于卸载了软件包造成的。笔记本电脑也不会告诉我电池电量。

答案1

不太令人满意的解决方案:

突然间,大量问题通过更新自动解决:标题栏中的标题字体和插件字体(如时间和日期、wifi 选项等)恢复正常字体大小。在终端 ( konsole) 中,光标(和字体)恢复正常。在kate(文本编辑器)中,间距和字体已设置回默认的等宽字体。现在可以使用功能键自定义亮度。现在可以看到电池状态。我无法追踪修复所有问题的更新,我附上了更新日志。“暂停”功能现在正在运行(之前不起作用)。

持续存在的问题:

Chromium 一直要求我将其设为默认浏览器。登录屏幕上的背景图像不断放大。


新问题:

现在登录屏幕中的背景图像永远无法正确呈现(即使正确输入密码也无法正确呈现),并且 KDE 徽标的动画已更改(即它最初是从上到下,透明条相互覆盖,现在是从右到左,静态条)。当移动到不同的虚拟桌面时,左上角将显示一个约占屏幕四分之一的黑框。
