(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:
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).
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.
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 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.
