(c) How do I check that runtime pm and vga switcheroo are enabled in my kernel. (Sorry, but I am a newbie to Linux).
If you have your .config (which, depending on options, may be visible from /proc/config.gz), you can look for
CONFIG_VGA_SWITCHEROO CONFIG_PM_RUNTIME
Make sure both of those are set to 'y'. (This is only for optimus-type systems, of which I'm assuming yours is one.)
(d) I cannot be sure about this as well. AFAIK, the nouveau module is built into the kernel. The modinfo result is as below:
There is no config.gz file in my system. I have tried using "locate" as well. Is there some other way I can find this out.
xf86-video-nouveau is the xorg ddx which interacts with the kernel driver. In some distros, for maximal confusion, it is called something else, like xorg-xserver-video-nouveau or something like that (don't have the exact name, sorry).
Can you please tell me how to find out (or search) if this is the case. Even if you can tell me where and how to look for, I will follow.
Actually I am working on some OpenGL/GLSL projects, for which I need GLSL 4.3, which I believe is still not available in nouveau driver. I was looking forward to be able to install the latest NVIDIA drivers. Will mesa 10,2-rcl solve this issue? Can you please recommend any other solution.
The latest mesa based DRI drivers through yum is listed as 10.1.1. Will it work?
Mesa 10.2 will support a few more extensions which are part of GL4+, but will not provide all the features required to advertise GL 4.0 support (or GL 4.3, obviously). You can see the general progress of things at http://cgit.freedesktop.org/mesa/mesa/tree/docs/GL3.txt.
However it's rare to need ALL of the features available in GL 4.3, so chances are you could restrict yourself to a lower, supported version + a few extensions.
Also note that GK208, while covered by the nvc0 driver, has en some extra-special issues that the GK10x cards (and GF1xx cards) don't have. Hopefully they'll be resolved semi-soon, but the hardware is not easily available.
