很大概率是因为 apt upgrade 后内核更新，驱动的dkms 没有自动更新，这时候可以在grub2处选择返回之前的内核

如果这时候正常进入了，这时候先检查 /lib/modules/[内核号]/updates/dkms 有没有东西，如果路径都不存在那么基本就是上面说的情况了
接下来

sudo apt install --reinstall linux-headers-6.12.111+deb13-amd64  #这里以我的内核号为例

sudo dkms autoinstall -k 6.12.111+deb13-amd64

sudo update-initramfs -u -k 6.12.111+deb13-amd64

重启之后，问题就完全解决了，可以正常进入了

代码、命令行输出等，请放到代码块中，比如：

```
Starting accounts-daemon.service - Accounts Service…
[ OK ] Started anacron.service - Run anacron jobs.
Starting avahi-daemon.service - Avahi mDNS/DNS-SD Stack…
[ OK ] Started cron.service - Regular background program processing daemon.
Starting dbus.service - D-Bus System Message Bus…
Starting e2scrub_reap.service - Remove Stale Online ext4 Metadata Check Snapshots…
[ OK ] Reached target getty.target - Login Prompts.
```

来回报楼主，仅仅因为看到楼主的内核版本是111,我也换软件源更新内核为111了，意外的是，浏览器版本比forky 版本高，更新后问题解决，看到楼主信息，一共解决3个问题，太值得了。

哦，是哦，这次更新，是手动安装，不是自动的。安装了linux-image-6.12.111+deb13-amd64,还要安装对应的hesders,dkms是在hesders里。
