<div>
<pre>I have a lenovo ideapad 720s (4k screeen). I installed ubuntu on dual boot and
with ubuntu there is a weird screen flickering which comes right after grub
menu and persists. I have never faced this on Windows and therefore driver
issues can be ruled out.
I have tried different os : fedora, mint, ubuntu and the issue persists with
all. here is a video for the same :
