Ubuntu 18.04 is too slow on my Asus r558ur with 8GB RAM, 8GB swap area, 2GB Nvidia GeForce 930mx. All the graphics elements seem to appear in a sliding motion with some lag and even dragging windows seems to flicker slowly. On booting from Live USB everything works fine though. Installation is done in Legacy BIOS.
