有时当我观看某个网站的视频时，视频和声音会卡在短暂的循环中，但我除了按住电源按钮关闭电脑外什么也做不了。知道会发生什么吗？我说的什么都没有，实际上是指什么都没有，包括切换到另一个终端。
我正在通过 syslog 挖掘更多信息，我希望它会有所帮助...但我不确定是否有真正的解决方案，因为日志：

您的 /swapfile 可能存在问题。让我们将其从 2G 增加到 4G...
笔记：错误使用rm和dd命令可能会导致数据丢失。建议复制/粘贴。
在里面terminal...
sudo swapoff -a # turn off swap
sudo rm -i /swapfile # remove old /swapfile
sudo dd if=/dev/zero of=/swapfile bs=1M count=4096
sudo chmod 600 /swapfile # set proper file protections
sudo mkswap /swapfile # init /swapfile
sudo swapon /swapfile # turn on swap
free -h # confirm 8G RAM and 4G swap
sudo -H gedit /etc/fstab使用或编辑 /etc/fstab sudo pico /etc/fstab。
确认 /etc/fstab 中的此 /swapfile 行...并确认没有其他“交换”行...在此行中使用空格...确认没有制表符...
/swapfile none swap sw 0 0
reboot # reboot and verify operation
