[SOLVED] Sony VPC-Z11 and intel video

borisko · 07-14-2010, 09:06 AM

Hello!

I have a sony vaio vpc-z11 laptop.
It has two graphic cards: intel and nvidia.
I am trying to use intel card.

The colors are very strange: in default framebuffer console the white color is being showed as purple color, default KDE screen looks very strange (fb and X)

Xorg.0.log: http://pastebin.com/NuKnr171
dmesg: http://pastebin.com/zeRtWqFw
lspci: http://pastebin.com/PdGPsv2e

I use Slackware64-13.1 and linux-2.6.34.1-vanilla.

What can I do?

Not sure why you would prefer the Intel card, because if I had to choose, I would choose nvidia.

Anyway, why not try installing the intel drivers from Salix:

They use a different version of the drivers that I've found to work much better.

I want to use intel because it uses less energy and isn't so hot as nvidia.

Thank you for the advice, I will try it next week.

Seriously ? By how much ?

hot or not the nvidia is much better, those intels are terrible cards.
I have a thinkpad with an intel and I just hate it.
almost no 3D is rendered correctly (weird artifacts and colors break through the edges of objects)
if you only want to use it for a 3d desktop, it should be ok
if you want to do any gaming or real 3d stuff, you'll just be disappointed.

On Windows I have an extra hour on battery with intel card.

I understand, that intel card is bad: I had a laptop with it. But it is enough to use firefox and ssh.
For gaming, I will switch to the nvidia card.

What nvidia card is it, I'm sure you can enable 'coolbits' and underclock the card when you're not gaming. I know this for sure reduces both the temperature and the power consumption of the card ... I've done this for the temperature part in the past.

But the problem is not nvidia's optimisation; the problem is with intel drivers
