Lenovo T410 - issue with i5 520M integrated graphics

landhar · 2010-04-07 16:47:24

Hi,

I recently installed Arch on a Lenovo T410. Following the guides in various wikis (Archwiki, ThinkWiki) I was able to configure everything without too much troubles...

But I have the feeling that the the integrated graphics chipset is not perfectly handled. I get this feeling when I run glxgears:

$ glxgears
307 frames in 5.0 seconds = 61.224 FPS
298 frames in 5.0 seconds = 59.490 FPS
299 frames in 5.0 seconds = 59.688 FPS
299 frames in 5.0 seconds = 59.688 FPS

These are the relevant outputs of lshw:

$ lshw -class display

Any ideas or suggestions will be welcome, also I would like to know if there are any relevant resources on the internet concerning integrated chipsets and the implementation status of the linux drivers.

Thanks,

You need .33 kernel, it will pass to [core] soon. Or .34 kernel, from -git [you can use AUR].

That's good news, I think I can live with it until then.

Can I ask you how do you know that ? I really want to understand how to look for this kind of answers myself. Using google for this problem hasn't been very helpful. But maybe I'm using the wrong keywords.

If your hardware is bleeding edge it's very likely to not yet be fully supported. In the case of Clarkdale/Arrandale i believe support is added in 2.6.33.
I suppose you could find that information by searching the forum for clarkdale, by browsing http://kernelnewbies.org/Linux26Changes or asking in irc / forums / usenet. But tbh i can't find much information about Clarkdale either.

For comparison though, i have ~800 fps on my Thinkpad X200s and 1100 fps on my i3-530 machine (Clarkdale) with kernel 2.6.32.10. Kernel 2.6.33.2-1 (testing repository) gives me ~800 - 900 fps.

demian

Thanks demian, your information was very useful. I can't believe I missed the codenames Clarkdale/Arrandale, adding these keywords to my searches gave me way more helpful resources.

Good to know, I'm likely going to be ordering a T410 soon.
