我的 Ubuntu 22.04 会定期冻结。这种情况随时可能发生，但似乎在使用 Web 浏览器时最常发生。我不确定这是软件问题还是硬件问题。
我附上了常规启动日志来帮助您更好地理解我的问题。

答案1
系统“冻结”通常是由于运行过多、过大的程序，导致可用内存不足造成的。使用free来查看是否有交换空间，阅读man mkswap swapon fstab fallocate来创建一些交换空间。交换空间必须是连续的。使用mkswap或fallocate，而不是dd。传统上，建议使用 1.5 × RAM 的交换空间，但 YMMV。如果您不打算让系统休眠，则可以拥有少于 1.0 × RAM 的空间。
