lspci

lspci is a utility for displaying information about PCI buses in the system and devices connected to them

List hardware

lscpi

List hardware data

lspci -nnk

Show kernel drivers handling each device

lspci -k

Show numeric ID's

lspci -n

Show VGA controller we got installed

lspci | grep -i VGA

What GPU is used

lspci -nnk | sed -n '/VGA\|Display\|3D controller/,+4p'

Show builtin modules only

lspci -nnk | awk -F': ' '/Kernel modules:/ { print $2 }' | tr ' ' '\n' | sort -u

Another example to see what builtin kernel modules are used

lspci -nnk | sed -n 's/.*Kernel modules: //p' | tr ' ' '\n' | sort -u

Show what each builtin module belongs to

lspci -nnk | awk '
/^[0-9a-f]{2}:/ { dev=$0 }
/Kernel modules:/ { print dev "\n  -> " $0 "\n" }
'

Get information on your graphics card on linux (such as graphics memory size)

lspci -v -s `lspci | awk '/VGA/{print $1}'`

Show detailed information for a single PCI device

lspci -nnvvv -s 00:14.2

Show both textual and numeric ID's (names & numbers)
