Q. I have a quick question for you, Vivek: I’m trying to find out my NVDIA display card memory size. I’m using Fedora Core Linux. How do I find out my VIDEO Card Memory size?
A. you need to use lspci command. It is a utility for displaying information about all PCI buses in the system and all devices connected to them.
If you just type lspci, you will get output as follows with the list of attached PCI cards:
$ lspci
Output:

You need to use string called devices in the specified domain - 00:02.0 VGA (highlighted in red color to display memory info);
$ lspci -v -s 00:02.0
Output:
00:02.0 VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 03) (prog-if 00 [VGA])
Subsystem: Giga-byte Technology Unknown device 2562
Flags: bus master, fast devsel, latency 0, IRQ 177
Memory at d0000000 (32-bit, prefetchable) [size=128M]
Memory at d8200000 (32-bit, non-prefetchable) [size=512K]
Capabilities:
This listing shows an Intel video card with 128 MB of video RAM. If you cannot find devices in the specified domain use following command and look for your display card name and memory field:
$ lspci -v | less

How do I check the amount of video card memory being used?
Thx, that helped me, but waht means “access denied” after the “capabilities”? That means my vga card is not in use? (I think)
Thank you but can you clarify; how do you view video memory in use additionally?
When I follow the above instructions, I get a much lower amount of memory than I know what is on this particular video card. The need for this is when I don’t know how much memory; on a laptop for instance.
@Fox
I don’t know why exactly the capabilities require root privs but that seems to be the case. Try:
sudo lspci -v -s 00:02.0
what means “access denied” after the “capabilities”?
Do use superuser. #sudo lspci -v -s 00:02.0
how do i find how much memory my video card has?
