Linux graphic artifact IEGD 10.3

RHane — Wed, 19 May 2010 14:21:45 GMT

Hello,

I'm new to the community, and first, thank you to Intel to give us the helpfull IEGD tool.

But I have got a problem with IEGD 10.3.1.

When I switched from one virtual terminal to another (with CTRL+ALT+Fx), I have got graphical artifacts and freeze.

I'm working on a Intel Atom D510. Do you know if there is a solution to this problem?

Thank you!

Ok, I've tried with 3 differents kernels (2.6.31.13; 2.6.33 and 2.6.34) and there is no difference.

I've also founded that you can start once the X server, and after killing it, you're not able to start it a second time.

Can someone help me?

Hi Rhanesse:

I know that we have some Intel folks looking into your message so hopefully you will hear something soon. In the meantime, any further details describing the failure you can provide might be helpful.

Thanks for your patience

Felix

I used to have the same problem, but it works well with kernel 2.6.34 now, I think you need a patch.
