This is what the lspci -v command shows in the VGA compatible controller section:

00:02.0 VGA compatible controller: Intel Corporation Atom Processor D4xx/D5xx/N4xx/N5xx Integrated Graphics Controller (prog-if 00 [VGA controller])
Subsystem: Dell Device 048e

Expansion ROM at <unassigned> [disabled]
Capabilities: <access denied>
Kernel driver in use: i915

i915 is only compatible with OpenGL 1.4 and cannot use shaders and I'd like to use some Open GL 2.0 functionalities.

Is it possible to update the drivers or is my hardware limited to OpenGL 1.4 ?
