在过去的几天里，某些桌面应用程序开始死机，只要按下Ctrl、Alt或Shift键，或者右键单击 GUI。这种情况发生在按下键盘/按下鼠标时。
例如，它发生在：
- 鹦鹉螺
- 更新管理器
- Rhythmbox 音乐播放器
- Gnome 截图
- Gedit（仅在右键单击和某些按键（例如Ctrl+ S）时崩溃）
并非所有应用程序都会发生这种情况。例如，Chrome、Clion (IDE)、Skype、gitk 不受影响。
如果我nautilus从命令行启动，则按Ctrl：
$ nautilus
Segmentation fault
运行它gdb显示以下回溯：

自从发生这种情况以来，我注意到鹦鹉螺看起来有所不同：
有什么想法可以修复此问题吗？

我相信您安装了 PPA（可能是 elementary-os/daily 或 ricotz/testing），它安装了与您的系统不兼容的 GNOME 库（或多个库）。
您应该清除安装了新版本库的 PPA。
如果你没有安装ppa-purge，请运行
sudo apt-get install ppa-purge
安装完成后，使用以下命令删除 PPA
sudo ppa-purge [ppa:ppa_team/ppa_name]
