如何解决 Xorg 启动问题？

我使用的是 Arch Linux，并且使用了 awesome wm，一切都运行良好。我安装了 plasma-meta 包来尝试 KDE 5，因此在重新启动系统后，X 无法启动。Lightdm、sddm 失败并且startx无法正常工作。我创建了这个线程在 Arch Linux 论坛中。

我搜索了一下这是什么意思，它应该与完整根分区有关，所以，

df -H

Filesystem      Size  Used Avail     Use% Mounted on
/dev/sdb2       4G   29M   3.8G      1%        /
dev             1.8G     0  1.8G          0%       /dev
run             1.9G   8.4M  1.8G       1%       /run
tmpfs           1.9G     0  1.9G         0%       /dev/shm
tmpfs           1.9G     0  1.9G         0%       /sys/fs/cgroup
/dev/sda1       20G  5G  14G       27%     /var
/dev/sda6       888G 828G  16G    99%     /data
/dev/sda5       20G  19G  278M     99%     /home
/dev/sda4       9.8G 221M  9G     3%     /tmp
tmpfs           362M     0  362M   0% /run/user/1000

我已经删除了 /home 中的一些内容，所以现在我有 78% 的使用率，但没有成功。

另外，xorg.conf 文件
