Ideapad 720S-13IKB (81BV) - Poor Graphics Performance

2019-02-25, 15:37 PM

Hi All,

 

I recently purchased an Ideapad 720S-13IKB with Integrated Intel UHD Graphics 620. When I play Youtube videos on google chrome or firefox, the video is not very smooth and if I move my mouse around, it gets even worse.

 

I've tried updating the graphics driver and the lenovo system update tells me I already have the latest version. I actually bought two of these laptops and the first one had this issue as well so I don't think it's hardware. 

 

I'm just trying to get the basic graphics performance that anyone would ask from a laptop, not trying to run games or anything. I feel like it's a waste to have a 4K screen if videos won't even play correctly.

 

Any advice? Thanks in advance.

I have the exact same laptop, linux runs a lot better. I don't know what lenovo has done to make this laptop run so slowly on windows to the point where it makes me want to chuck it across the room.

Hi, 

 

Sorry to hit a post from 10 months ago, but I was wondering what linux you are running on the laptop.

 

I am now on my third distribution (all Debian), and have been experiencing terrible screen flickering.

 

Only time it doesnt flicker is when I dont have the intel i915 driver module running, but then I end up loosing most other video related settings functionality.

 

Any input would be appreciated.

 

Thanks!

It works on any distribution as long as you boot with the following kernel parameter, i915.fastboot=1. The flicckering will come back everytime a modeset happens, so from resume or sleep. There is a bug report with some progress on it but I have since given up on this laptop and ordered a t495.

 

Hope this helps!
