2.2 新建一个交换分区
2.3 指定交换分区的位置 1 问题描述 CPUG6900E OSubuntu22.04 Kernel6.8.0-49-generic 使用“echo disk /sys/power/state”命令进入 S4但是无法进入 操作如下所示。
rootjw-Windows-cpmpact-G6900E:/home/jw# echo disk /sys/power/state
bash: echo: 写入错误没有那个设备
rootjw-Windows-cpmpact-G6900E:/home/jw#
2 解决过程
2.1 查看内核日志 进入 S4 失败后使用“dmesg”命令查看内核日志内核日志如下所示其中重要的日志为“PM: Cannot find swap device, try swapon -a”提示找不到 swap 设备。执行“swapon -a”命令无法解决问题。

2.2 新建一个交换分区 在安装系统时手动分区新建一个交换分区。操作过程如下所示。 点击“中文简体”然后点击“安装 Ubuntu”。 点击“继续”。 选择以下内容然后点击“继续”。 选择“其选项”然后点击“继续”。 如果原始硬盘有其他分区请先删除分区只剩一块空闲区域如下所示。 保留BIOS启动分区这个是必须的但是只要求大于1M就行我给32M使用的主分区。 EFI系统分区这个也是必须的也不用太大给512M就行逻辑分区。 交换空间系统进入 S4 必须要有的分区如果内存低的话1-4G建议为物理内存的两倍4G的话要么等于物理内存要么物理内存2g左右我这里直接给 16G。 /boot分区/boot分区在挂载点选项中这个也是必须的存放的是linux内核和启动引导文件。给2G逻辑分区。 安装系统的分区这个分区的大小就看情况而定了如果装的软件多就大点。当然安装软件的目录也可以单独分区我这里把剩余的储存都分到这个区域。需要注意这是系统必须主分区 点击“继续”。 点击“继续”。 填写信息和密码点击“继续”。 等待安装成功。安装成功后使用“swapon --show”命令查看交换分区可以看到有/dev/sda3 交换分区而且类型为partition。
jwjw-EloPOS-Compact-G6900E:~$ swapon --show
NAME TYPE SIZE USED PRIO
/dev/sda3 partition 15.3G 0B -2
