我的问题与任何交换的使用都会导致整个系统冻结，仅在 18.04 中。但没有人回答这个问题...
当我玩图形密集型游戏时，整个系统会在某个（可变的）短时间内冻结，甚至三指敬礼都不再起作用。
我编写了一个小 shell 脚本，它在循环中记录了内存使用情况...
logdump=/home/`whoami`/log/`date +"memory.%Y%m%d%H%M%s"`
date +"Memory log: %c" > $logdump
free -m >> $logdump
sleep 30
while ((1)); do
date +"%T" >> $logdump
free -m | tail -n 2 - >> $logdump
sleep 30
done
输出是...

巧合吗？我想不是。
