'i965_dri.so does not support the 0x1916 PCI ID' I had to install manually kernel 4.4.6 so everything worked properly, however I noticed compiz was taking more than 60% cpu. I necessarily have to work with Ubuntu 14.04 but it was not recognizing my laptop's hardware (skylake not supported). I recently bought a laptop with the same processor and I was experiencing problems with graphics. I'd like to share my experience with a similar issue. Note : I am wondering if changing the backend to compiz instead of metacity would make things better ( I highly doubt it ). I am really attached to the ubuntu gnome environment but I don't recall having any of this problem before, so my guess is that the hardware is not fully supported at the moment ? I have a few weeks to decide if I want to keep the laptop and I want to be sure to nail the origin of the problem before returning it to regret in the future.

Installed the proprietary intel cpu driver.

Installed intel graphics software, ( supposed to update all drivers, the release of this software is pretty recent ).

Upgrade to ubuntu 16.02 ( was running 15.10 ).

In comparison windows feels nice, but I prefer the linux environment. Scrolling webpages, scrolling pdf document are sluggish with a lot of lag, resizing windows is painfully slow, and the experience overall is not really good. Is this hardware supported 'fully' By linux (ubuntu gnome) ? I ask because everything seem so sluggish on my laptop.

I know this question might seem too naive but I've been looking quite a lot and didn't find any definitive answer. I just got a new laptop (razer blade stealth) with the following configuration :

Skylake gt2 hd graphics 520
