[SOLVED] How to check vram size?

GTX1650 with 4GB vram

$ lspci -v | grep VGA -A12
01:00.0 VGA compatible controller: NVIDIA Corporation TU117M [GeForce GTX 1650 Mobile / Max-Q] (rev a1) (prog-if 00 [VGA controller])
        Subsystem: Lenovo Device 3a43
        Flags: bus master, fast devsel, latency 0, IRQ 96
        Memory at d0000000 (32-bit, non-prefetchable) [size=16M]
        Memory at fce0000000 (64-bit, prefetchable) [size=256M]
        Memory at fcf0000000 (64-bit, prefetchable) [size=32M]
        I/O ports at 2000 [size=128]
        Expansion ROM at d1080000 [virtual] [disabled] [size=512K]
        Capabilities: <access denied>
        Kernel driver in use: nvidia
        Kernel modules: nouveau, nvidia_drm, nvidia

The vram that the command "lspci -v | grep VGA -A12" only shows is only 16MB+256MB+342MB,
it should be 4GB, so how to find out this size?

$ glxinfo -B
name of display: :0
display: :0  screen: 0
direct rendering: Yes
Memory info (GL_NVX_gpu_memory_info):
    Dedicated video memory: 4096 MB
    Total available memory: 4096 MB
    Currently available dedicated video memory: 1863 MB
...

What does "available dedicated video memory" mean?

Re: [SOLVED] How to check vram size?

I don't know what "Currently available dedicated video memory" means, but you should look at "Video memory" and "Dedicated video memory".
Other ways to check (but may fail):

It's interesting that "Dedicated video memory" and "Total available memory" are the same (nouveau driver have second value much higher).
This interesting thread is about that:

Dedicated Video Memory or VRAM is the fixed amount of memory installed on your graphics card.
