I'm posting today here because I would need some help about the new laptop i bought last week..
I bought a Latitude E7470 from Dell with the following specs :
- Intel Core i5 6300U
- Intel Graphics HD 520
I'm a Debian user, I currently use Debian 8.6 and I upgraded my kernel to a 4.2 because my wifi drivers needed to be at least 4.2...
Right now, i'm facing a problem while using desktop environment like Cinnamon. The system is telling me that i'm in a "Rendering Mode". I almost don't see any consequence except some :
- Videos and movie are sloooooow and not fluid.
I don't have many experience with Linux systems and I think it's caused by my graphics drivers.
And right now, i'm here tu get some help about what should I install, how to resolve this..
I saw different things I could download and install but I don't really know what should I do.. :)
So, if someone could help me to resolve this, and also understand why is it working like that, I would be grateful.
You can check to see which kernel module is used to drive the graphics with lspci -kvnn - I suspect you are falling back to generic unaccelerated graphics support. The easiest likely fix for that is to update your kernel - 4.7.x is available from backports.debian.org, which will probably have support for your GPU - if lack of support is the problem you are facing, thatr should do the trick.
