Graphics issues upon installation of NVIDIA drivers

wadawalnut · 2015-05-30 02:24:07

Until yesterday, I wasn't using the nvidia drivers on my laptop, but with that configuration it wouldn't resume after suspend. I decided to set up the nvidia drivers in an attempt to get rid of that issue. So I followed through the wiki instructions and some other forums online, and got the nvidia driver set up, which did in fact solve the resume issue! However, now I'm facing a more minor issue.
I find I only really notice this on terminal windows, and upon reason inspection it is only in certain background colors of the terminal that it is noticeable to me at all: the screen seems to display some sort of static. Picture something like static you see on a tv when you lose connection, except it's extremely faint, and the colors that make up the static are all very close to the background. It's very hard to explain, so I tried to see if a screenshot would show it, but after looking at the screenshot on another computer I couldn't see anything.
You could only really notice it if your eyes are fairly close to the monitor, so it doesn't bother me that much. Just now I know it's there so it's bugging me.
I'm not sure if this is related, but if I close my laptop for a while and then open it, just after the resume the screen is all static (exactly like you'd see on tv) but that goes away very quickly. And if the laptop isn't closed for a while, on resume the screen is all black but some seemingly random pixels are seemingly randomly colored.

In case this is important, I am on a Lenovo Ideapad Y500, which has an NVIDIA GeForce GT750M graphics card.

Here is my xorg.conf file, which I believe is where the issue stems from:

Uhh, are you sure you want your monitor to run at 32Hz?

...
Modes	   "1920x1080_32.00"
...

The static you might be seeing it the low refresh rate flickering. I'd set the refresh rate to 60Hz if "auto" fails to detect it.
