Corei5 3570k lagging very hard on desktop use

Hi my new CPU is a corei5 3570k with an integrated intel hd4000 graphics core. As I understand it, this chip should be sufficient to drive two displays and Gnome 3, making it possible to remove my graphics card. However when I do so, I inexplicably get massive lag (3-5 inoperably frozen machine) every few seconds and my second display doesn’t work properly either, not showing a mouse cursor, just a blank background with no interaction possible.

When I put back in my old hd4850 card, everything works fine and very fast. For some reason the integrated graphics are laggy, do you guys have any idea how to debug this? What could be the cause?

My mainbaord: Asrock H77 Pro4 / MVP
CPU: corei5 3570k

I would prefer if I could just use the integrated graphics, because the fglrx drivers are glitchy and my graphics card fan is broken too, so it’s all a mess. I was under the impression that Intel had good support for Linux…? I already did a ‘zypper dup’.

i don’t know much about that new CPU, but i do know your graphics card
has lots of on-board VERY FAST video RAM, and the GPU on that card ONLY
has to crunch video supporting numbers…

the newest CPU you can buy might be able to do all the CPU stuff AND
crunch all the GPU numbers needed to push the images out, but it just
can NOT get the job done without the VERY FAST video RAM…

last: i wonder how often and why do you do a ‘zypper dup’??
i can only guess you think that is what you are supposed to do…

it is dangerous to pull the ‘zypper dup’ trigger.

Upgrade your kernel to 3.4.xx and enjoy your new hardware. That’s what I had to do, even though I went the tumbleweed road on that machine.

Nikos78, thank you that worked except for WebGL and if I remember correctly, there is an “Experience: Advanced” mode for Gnome 3, but for me it’s still set at “Standard”.

Hi Nikos! What’s so important about kernel 3.4.xx? Is there a semi-technical explanation of why it works better/faster? I’m curious if it will affect my AMDs.

Fixes problem with newer Intel CPU’s with integrated video. Probabky other stuff but IMO if it ain’t broke don’t fix it.

When it comes to excellence in processor performance, Intel continues to pull all the stops with its newest entries into the market. Launched in early September, 2009, the Intel Core i5 processor is one of Intel’s recent innovations, which offers smart performance with a speed boost. This processor delivers solid performance for day-to-day applications, not to mention its ability to increase speed as required for the more demanding tasks. And already, it’s being touted as the mainstream version of Intel Core i7.

Intel Hyper-Threading Technology features 4-way multi-task processing which enables each core of the processor to handle 2 tasks simultaneously, thus delivering the performance required for smart multitasking. No matter how many applications you are working with at the same time, you and your PC will not be slowed down at all.
Intel HD Graphics technology is included to provide excellent visual performance for rich color, sharp imaging, as well as life-like video and audio. You can now enjoy your movies and internet videos in high-definition, get full Microsoft Windows 7 support, as well as play popular game titles. You can do all this without the need for an extra add-in video card as this is all built-in.

Sorry for taking so long to reply even though I was directly addressed, but as gogalthorp wrote, indeed the 3.4 kernel has better support for this specific intel graphics (which by the way is broken in the 3.1.x series).

thank you that worked except for WebGL

I think we will have to wait for mesa 8.0.3 hitting the repos for that to happen…

If you are a bit adventurous (as you are when using a newer kernel) you
just can use the repository
for your version, it has at the moment Mesa 8.0.4.
I use that for quite some time now on my ThinkPad together with kernel
3.5 from kernel:stable and it raises the OpenGL version of my Intel
graphics from 2.1 to 3.0 (makes a difference for me since I do OpenGL
