opengl with linux (current state)?

[noeska]

I have not touched linux for a while. Now i wonder what the state of linux drivers is compared to the windows ones.
Looking in on it it seems that there are more then one way to it on linux. E.g. for ati you have the official closed source drivers (x86 only) and there are supposed to be complete opensource ones (suposedly also with 3d support). What is the state with vertex and pixel shaders on these opensource drivers?

I have the latest Nvidia drivers on my linux box and it supports Opengl 2.0 just like the Windows versions.

I don't know about ATI though.

I'm using a Radeon M7 with open source drivers, however, as the card doesn't support shaders, I can't really answer wether the open source drivers support shaders. However, the open source drivers support much less OpenGL extensions than the propietary ones do. It might be a good idea not to demand too much in this department.
