I have a new Lenovo 300S-11 IBR ( http://shop.lenovo.com/gb/en/laptops/... ), 11,6" laptop with pre-installed Windows 10.

I tried installed Fedora 23 on this laptop, both UEFI and BIOS, and both have the same problem. Everytime it gets into the log in screen, the screen is always distorted until I log in. Everything is fine after I log in. The screen is always distorted when it displays log in screen.

This is what lspci reported on VGA,

# lspci -nn | grep VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation Device [8086:22b1] (rev 21)

And this is my system specs from Details,

Intel HD Cherryview

The graphic card is Intel HD Cherryview. I am new to Linux OS. Please help me. Any help is appreciated.

Another note, the UEFI Fedora seems a little slower than the BIOS Fedora. I wonder if it is caused by graphics driver.

I also get something which i would call distorted login screen in the following conditions: I spend some time in a ssh terminal (Ctrl+F3, +F4, ...) and then when I come back to a graphical desktop, I am presented with a "distorted"/garbled screen. But the wallpaper is still discernable; after I login, all comes back to normal. I have a Gigabyte GTX760 running the Nvidia driver from rpmfusion. Nevertheless, unlike you, this scenario is THE only scenario where I notice this "distorsion".

now I notice that it also sometimes happens after I wake the computer from power saving mode (the computer is not suspended/sleeping/hibernating; just the monitor turned off after a while of idleness).
