How do I install the Intel Graphics driver in my system?
My computer is Dell Vostro 3400. I installed Ubuntu 11.10 recently.
Here is the graphics card informations:
00:00.0 Host bridge: Intel Corporation Core Processor DRAM Controller (rev 18) 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics > Controller (rev 18) 00:16.0 Communication controller: Intel Corporation 5 Series/3400 Series Chipset HECI Controller (rev 06)
How do I know if I need to update my graphics card driver and which one should I choose?
