Sorry, my bad! The partitioning is as follows:

# fdisk -l
Disk /dev/sda: 37.3 GiB, 40007761920 bytes, 78140160 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x20a0209f

Device     Boot    Start      End  Sectors  Size Id Type
/dev/sda1           2048  2105343  2103296    1G 82 Linux swap / Solaris
/dev/sda2  *     2105344 18876415 16771072    8G 83 Linux
/dev/sda3       18876416 78139391 59262976 28.3G 83 Linux

        Driver      "intel"
        Option      "Backlight"  "intel_backlight"
        BusID       "PCI:0:2:0"
It will take effect next time the X-server is started. See if that helps.
I added this file and rebooted. X won't start at all.

BTW, what do your current boot parameters look like? (Just in case tweaking is needed)
cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-4.9.0-1-default root=UUID=.....(not sure if this should be public, so I remove it) resume=/dev/sda1 splash=verbose quiet showopts plymouth.enable=0
