任务管理器显示 Java 和 dbeaver-ce 进程，但没有 GUI。
请告诉我为什么 snap 会停止工作？人们最常做的事情是什么导致 snap 坏掉？
另外，请不要告诉我重新安装 snap，因为我会丢失所有的数据库连接（我已经创建了很多）。（我刚刚重新安装了 Postman snap，丢失了所有包含许多请求的集合。）
或者，如果我确实必须重新安装它们，请告诉我一种保留用户数据的方法。
答案1
dbeaver 在我的 ubuntu 20.04 上运行良好
~$ snap info dbeaver-ce
installed: 7.3.0.202011291229 (93) 207MB -
我建议您检查目录 /home/opyate/.config/user-dirs.dirs 和上面目录的权限
我的具有以下访问权限：
-rw------- 1 koen koen 633 dec 3 20:58 user-dirs.dirs
-rw-rw-r-- 1 koen koen 5 dec 3 20:58 user-dirs.locale
这里讨论了导出/导入连接或保留 dbeaver 的设置：https://dbeaver.io/forum/viewtopic.php?f=2&t=906#:~:text=There%20is%20project%20export%2Fimport,keep%20all%20UI%20settings%20too。
简而言之 ：
有项目导出/导入功能（主菜单文件->导出/导入）。但最简单的方法是将 USER_HOME/.dbeaver 文件夹复制到另一台机器。这样，您也将保留所有 UI 设置。但在执行此操作之前，请确保在两台机器上使用相同的 DBeaver 版本。
对于 snap，.dbeaver 文件夹存储在这里
~/snap/dbeaver-ce/93/.local/share/DBeaverData/workspace6/General/.dbeaver
答案2
在会话中第二次打开 dbeaver 会出现问题。您可以通过按 alt-f2，然后键入“r”作为命令并输入 Enter 来解决此问题而无需注销。无论出于何种原因，Gnome shell 都不知道 dbeaver 何时终止，这会以全新状态重新启动 shell，因此您可以再次打开它。
