Yep.
Try to understand it's for nVidia GPU's ONLY.
No intel support.

All best

I understand, there is no really point that you have to scream at the end of the sentence. Please keep calm and focus on the goals ;)

This card its NVIDIA Optimus http://en.wikipedia.org/wiki/Nvidia_Optimus / Switching from INTEL / NVIDIA Mode when the apps asks for GL mode. I didn't mentioned also, that I have second same laptop with same GPU and I mining there with latest cudaminer using scrypt around 25Kh/s.

Cheers.

Optimus requires software like bumblebee and the "optirun" tool to launch cudaminer. See a related forum posting I made on the bitcointalk thread.

[michalsarna]

There is no mention of nVidia GPU in what You have posted. So try to be more specific with a hardware configuration next time.

All best.

Hi Christian. I think I have read - but going to check anyway to make sure. On my second setup - I didn't use explicity optirun neither bumblebee - latets versions of nvidia driver 319 provides support for it (I have them installed not trough dpkg).

Packages which I have installed they are from 304 to provide depends for headers but there is also binary 319, which supposed to clean after not necessary parts 304.... Maybe its related with driver itself, but I have seen also other similar issues with segfaults.

[bluszcz]

@michalsarna Your comments are not bringing literally anything to this issue, so I would ask to not interfere until you may bring something more helpful.

@cbuchner1 What kind of debug maybe be helpful for you? I have reinstalled drivers making sure that I have running 319 and 235 (not at once obviously) - drivers in this version provides support for optimus turning off intel one - but it is still segfaulting. I checked on another another computer with different NVIDIA optimus - and cudaminer works well there.

Bluszcz says in issue #3 that he has solved this issue by re-installing his drivers. This should be closed.

[bluszcz]

Yes. The NVIDIA drivers they have "-optimus" switch which allows to install with the support for Optimus cards. Happy mining.
