刚刚在一台新机器上安装了全新的 Ubuntu。除了鼠标周期性延迟之外，我非常高兴。即使在延迟期间，其他一切似乎都运行良好。鼠标是无线的，并附带键盘（MS）。我有英特尔 i5 处理器和英特尔 UHD 显卡。我检查了日志，我看到的唯一可疑的事情已经在这里提到（但仍未解决）：
https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1857392
我还确保通过软件和更新更新了所有内容。我已将前置麦克风和辅助插孔与耳机连接起来（2 到 1 个辅助插孔）。
任何帮助，将不胜感激。

交换
您的交换分区超过 37G。让我们将 37G 的交换分区更改为 4G 的 /swapfile。
在里面terminal...
sudo swapoff -a # turn off swap
要编辑 /etc/fstab，请使用sudo -H gedit /etc/fstab或sudo pico /etc/fstab
注释掉以下行：
UUID=9cd65f59-278f-416d-aede-189ce6ff4086 none swap sw 0 0
保存编辑并退出编辑器。
笔记：命令使用不当dd可能导致数据丢失。建议复制/粘贴。
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
确认 /etc/fstab 末尾的 /swapfile 行...并确认没有其他“swap”行...
要编辑，使用sudo -H gedit /etc/fstab或sudo pico /etc/fstab
/swapfile none swap sw 0 0
保存文件并退出编辑器。
reboot # reboot and verify operation
注意：37G 交换分区（/dev/sda3）不再使用，可能会被删除，并且未分配的空间可能会使用 添加回您的 Ubuntu 分区gparted。
