Let's assume, that you have several graphic cards on your desktop, and you want to see more details about them, because you dont remember exact model number and other stuff.
My first look is always
lspci but it wont give you the full view.
Before using lspci, it's a good idea to update PCI ID list with the latest version

Another metchod to detect a video card is
deadfish ~ # lshw -short -c video H/W path Device Class Description ====================================================== /2/100/2 display Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller /2/100/1c.4/0 display Hawaii PRO [Radeon R9 290] /2/100/1c.5/0 display Hawaii PRO [Radeon R9 290] /2/100/1c.6/0 display Hawaii PRO [Radeon R9 290] /2/100/1c.7/0 display Hawaii PRO [Radeon R9 290]
When you need even more details about your card, you have to use some tools that comes with drivers.
For ATI it will be
atitweak and for NVIDIA you will use
