After a fresh Ubuntu 17.10 installation, my screen looks like this:
I cannot read a single character on the screen because of that weird screen noise. Also, my screen's resolution is 2560*1080 but I only get 1920*1080 input signal to my monitor, and the original content of the the display gets shrunk into that smaller resolution.
I can solve this by switching back to Xorg from Wayland.
But I would like to use Wayland if possible because its faster. Thank You!
Edit: my VGA: AMD Radeon RX480 driver is amdgpu and my monitor is LG25UP and connected with HDMI to my VGA.
