I am new to Linux OS. I have installed Ubuntu 12.04 on HP Compaq NC6120 laptop and I have an issue with Intel 915GM/GMS/910GML Express Graphics Controller driver. It is shown as unknown and I think this is what causes performance issues.

$ lspci -nnk | grep -iA2 vga
00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller [8086:2592] (rev 03)
    Subsystem: Hewlett-Packard Company NX6110/NC6120 [103c:099c]
    Kernel driver in use: i915

What should I do to fix the performance issues?
