I have a ASUS ROG G551VW and was able to install Ubuntu via this post.
Note that my laptop has a 4K display.
Every thing was smooth during live boot and testing but when I actually installed Ubuntu, each frame has to be drawn from the top, row by row until the whole frame was drawn.
It takes about 1 or 2 seconds to actually finish drawing a frame and start another one.
I have tried purging NVIDIA drivers and reinstalling them using TTY, but it didn't seem to help me. I also tried both Ubuntu versions and got the exact same problem with each of them. I also tried installing from scratch.
Please note that this laptop's GPU is GEFORCE 960M.
Is there any way of fixing this issue?
