Thank you Denis,

I tried with the following Ubuntu-built kernels, all having the issue:
4.15.0-45, 4.15.0-44, 4.15.0-20.

It happens on both 32bit and 64bit installations.

The failed units logs are:
systemctl status gpu-manager: https://termbin.com/kkix
systemctl status lightdm: https://termbin.com/ybev
lightdm.log: https://termbin.com/ssrb

The weird part is that I don't see xorg segfaults or /var/crash/* reports or
anything, the only error I got was that xinit line that I mentioned, "i965:
Failed to submit batchbuffer: Invalid argument"

I have the `lspci` results from 4 schools so far, they're all 8086:1912 (HD
Graphics 530), although from different vendors, ASUS, Dell etc.
