PS:

Assuming that tmpfs should be the culprit, it's possible to assign more
RAM to tmpfs by an entry in /etc/fstab.

  tmpfs          /tmp        tmpfs nodev,nosuid,size=3G     0 0

This is just an example, replacing 3G by any other value might be
appropriate. The default without an fstab entry is half of the RAM.

Perhaps taking a look at the frame buffer, by e.g.

  sudo hwinfo --framebuffer

is useful, too, assuming that the graphics doesn't have it's own memory.
The shared video memory could be changed by the BIOS settings.
