Two days ago I installed OpenSUSE 13.1 (Gnome 3.10) on my new Dell M3800 laptop, which is a new model with Intel Core i7-4702HQ with integrated Intel Graphics (HD4600) and a Nvidia Quadro K1100M GPU. I’ve had some issues getting any of these to play along nicely, and hoping for some help that steers me into the right direction. I want to point out I’m a newbie, so I might have overlooked the obvious here, but let me start by explain what the problem is.
On installation, the Intel GPU works out of the box. Well sort of. I do get an image, and all looks well, but everything is somewhat sluggish and laggy. Scrolling in Firefox/Chrome gives you a feeling you’re running on some really old hardware, and all Gnome effects feel the same. Compared to my Samsung Ultrabook, which runs Xubuntu on MUCH less powerfull hardware, it’s a clear win for the Samsung.
I’ve been trying to find some information regarding the HD4600, and the only thing I’ve found is a recommendation to try to upgrade the Kernel which I’ve done (3.13) but the results are basically the same. I also tried getting the Nvidia GPU working (Quadro K1100M), but it seems it’s not yet support by Nvidia except for a beta which didn’t work for me. I’m fine with waiting until a proper driver exists for the Nvidia, but it would be nice to have at least the HD4600 running smoothly. I also need to point out the M3800 has a very high def screen, 3200x1800, so there is a lot of pixels for it to move around. I would ever assume it has enough power to run Gnome 3.10?
Any help is much appreciated, and thank you in advance!
This is a fresh install, I’ve tried some distros the last couple of days to see how they handled the hardware + HiDPI display and decided on OpenSUSE. Thanks for the link, great stuff! Will install bumblebee, guess it’s needed anyway to keep the Nvidia GPU in check.
Here is the output:

Did a fresh install just in case, installed bumblebee which seems to be working in regard of shutting down the Nidia GPU (power consumption went down from 28 W to around 17 W). Still having issues with the Intel gpu performance though. When running the browser (both Firefox and Chrome) in windowed mode that covers around 2/3 scrolling actually runs smooth, anything above that lags. All GUI elements seem sluggish also, so something is not right.
Sorry for the late reply, I’m currently relocating to a different part of the world so had to put this aside for a while. I’ve tried switching to UXA, made no visible difference. Unfortunately there are no Optimus settings in BIOS, same goes for GPU memory allocation (which I’m guessing is also set in BIOS?).
I’ve noticed a few more things, not sure they are related by thought I’d bring them up anyway:
In firefox/chrome, I can see some graphical corruption - small black cluster of blocks that appear/disappear during scrolling. Not always, but now and then.
Grub startup screen is extremely slow. It gets drawn bottom up, takes around 1.5 seconds.
