I am having trouble trying to get my graphic card to be recognised, not just recognised, but for it being able make use of it's OpenCL/GL drivers for use in Gaming mostly and BitCoin mining.
I have ASUS N56Vz running Linux Mint 16(petra) (Cinnamon), wasn't too sure if it be suitable to post about Linux Mint here, but Linux Mint and Ubuntu aren't all that too different from each other, issue happens on either systems.
that one annoying problem I can't seem to find the answer to after searching the Internet, BitCoin miner is unable to find the GPU or CPU built-in to the system. Giving me that
No GPU detected and the
Could not find libOpenCL.so.*
Linux ASUS 3.11.0-12-generic #19-Ubuntu SMP Wed Oct 9 16:20:46 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
Now before coming posting my question here I did read over this topic here » Open cl in intel, I followed that and got Intel CPU/GPU to be detected properly in Bitminter, just not my secondary built-in graphics card which is NVIDIA GeForce GT 630M.
lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 630M] (rev ff)
they seem to be detected correctly by the system, but they don't recognise when it comes to CPU/GPU computing for Bitminter for BitCoin mining. Also I do notice in playing games too that the graphics drivers aren't working as it should be. For some games they work just fine, but for some other games I get black textured graphics, or even white textured graphics, really bit confused why it says they are being detected yet they don't function as they should be doing normally for other stuff.
after running a test here's my output for Intel HD Graphics using the Beignet to test for the OpenCL driver.

I have latest Nvidia drivers installed, or what I think is the latest that can be fetched from the repository
nvidia-319-updates I have checked with my model of Intel CPU and NVIDIA card that they are OpenCL/GL compatible. NVIDIA GeForce GT 630M has CUDA support built in according to NVIDIA's driver homepage.
I know graphics support for NVIDIA is a little sketchy and a bit unstable as they are for Linux still currently, even after installing NVIDIA's own official driver releases. My ASUS laptop is capable of Hybrid graphics switching, and as far as I've been able to search up on Google, that it is possible to do that on Linux, but involves a bit of tweaking and such so it can switch between Intel HD Graphics/Nvidia at any time without having to reboot.

as seen there it says
vesa is unloaded, I dunno if this is the cause why it doesn't want to load properly, I should probably look at trying to enable them somehow.
Back to the main issue, the issue being the
libOpenCL.so file being missing on the system, which is suppose to be inside
/usr/lib/ or something like that, just running
none to the terminal screen. I have
bumblebee-nvidia installed too but this doesn't seem to make it work either as well as CUDA related libs.
I'm running around a bit lost trying to find an answer to getting this to work and not turning up much results besides Googling certain specific errors that pop-up.
