When I put lspci | grep VGA
I got these
00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 18)
01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 435M] (rev a1)
Is there any way to know more detail on them? For example My nVidia is 1GB is there any command line which shows nvidia is 1GB?
