lspci | grep -i "vga"
The commandlspci | grep -i "vga" extracts and displays your system's graphics
hardware details, specifically identifying older types of cards/controllers (see below).
Breakdown
-
lspci: Lists all PCI (Peripherial Component Interconnect) buses and devices attached to your motherboard (such as GPUs, audio cards, and network adapters). -
| grep -i "vga": Pipes the massive list to grep, searches case-insensitively (-i) for the word "vga" (which isolates graphics controllers), and prints the matching linedetails.
