我在我的 MSI GF63 笔记本电脑上安装了 Ubuntu。我的规格如下： Intel Core i5 9300H（四核）8 GB RAM nVidia GTX 1050 Intel 660p 512GB SSD（140GB + 15GB Swap for Linux）

我的系统在加载时间歇性冻结。如果我播放音乐，运行 nodeJS 和 Java 服务器，打开 Firefox 和 VS Code。系统间歇性冻结。我尝试让 htop 保持运行以查看是否遇到任何瓶颈，但在这些情况下，我发现 CPU 和内存都没有耗尽容量。通常音频不会滞后，音乐和通话大部分都保持不变，即使有时它会有点卡顿，但鼠标不会移动，Alt + Tab 也不会工作

我尝试按照此处的建议安装 DRM KMS，但无济于事，我尝试切换到我的 nVidia GPU 使用 X-Server，但这也没有解决它。由于无法诊断出任何瓶颈，因此我几乎没有选择余地。

➜  ~ free -h

➜  ~ sysctl vm.swappiness
vm.swappiness = 60
➜  ~ grep -i swap /etc/fstab
# swap was on /dev/nvme0n1p6 during installation

Gnome 扩展命令返回以下内容：

➜ ls -al /usr/share/gnome-shell/extensions         
total 16
drwxr-xr-x 4 root root 4096 Feb  3 23:54 .

➜ ls -al ~/.local/share/gnome-shell/extensions     
ls: cannot access '/home/maverick/.local/share/gnome-shell/extensions': No such file or directory

重新启动时的最高输出

在没有过度负载的情况下观察到滞后时的最高输出

free -h在没有过度负载的情况下观察到滞后时的输出

              total        used        free      shared  buff/cache   available

输出为lshw -C memory
