我已经在互联网上搜索过有关这个问题的信息，每个人的错误似乎都与我的略有不同，但无关。
Rosegarden 昨天还在运行。现在，每次它都会毫无例外地显示启动画面，一些窗口的提示，但随后屏幕区域会“冻结”并且不会刷新（您可以通过将窗口拖到该区域上来“绘制”该区域 ;)）
我试过：
sudo apt-get purge rosegarden
sudo apt-get autoremove
sudo apt-get install rosegarden
看似全新的安装，事情却以完全相同的方式发生。
这是终端输出：

就是这样。Rosegarden 每次都挂在那里。我不知道是什么可能导致某种错误，这种错误会在全新安装后持续存在。它似乎还因为某种原因无法加载任何字体……
答案1
正如您在问题中所述：
删除列出的所有内容
find ~ -name "*rosegarden*"
在主目录下修复了这个问题。Rosegarden 创建了一些隐藏目录和文件，我猜这些目录和文件已经损坏。
在这种情况下，我会查看导致这种情况的原因并提交错误。
