I need to find out how much video/graphics memory is in my Acer Aspire 3680-2419 laptop so I can try to install a game using Play On Linux. I know it has a Intel Graphics Media Accelerator 950 that's most likely integrated onto the motherboard but I'm not sure. But since I'm fairly new to Ubuntu and Linux in general I'm not sure how to find that info.

There are various tools that can do this, including:

  1. inxi

    $ sudo apt-get install inxi
    $ inxi -G
    Graphics:  Card: NVIDIA G86 [GeForce 8400 GS] 
       X.Org: 1.14.3 drivers: nouveau (unloaded: fbdev,vesa) Resolution: 1920x1080@60.0hz 
       GLX Renderer: Gallium 0.4 on NV86 GLX Version: 3.0 Mesa 9.2.2
    
  2. lshw

    $ sudo apt-get install lshw
    $ sudo lshw -C display
      *-display               
           description: VGA compatible controller
           product: G86 [GeForce 8400 GS]
           vendor: NVIDIA Corporation
           physical id: 0
           bus info: pci@0000:02:00.0
           version: a1
           width: 64 bits
           clock: 33MHz
           capabilities: pm msi pciexpress vga_controller bus_master cap_list rom

  3. lshw-gtk

    $ sudo apt-get install lshw-gtk
    $ sudo lshw-gtk
    

    Then:

  4. hardinfo

    $ sudo apt-get install hardinfo
    $ hardinfo
    

    Then:

    enter image description here

While only hardinfo actually reports the memory available to the graphics card, it is trivial to get that from Google. For example, searching for GeForce 8400 GS finds an NVidia page which tells me that my card has 256MB of memory.

  • It is not trivial. For example, my gfx card doesn't have a standard memory listed (I know it's 3GB because the OEM listed 3GB and nvidia-smi confirms it). By the way, I don't think those memory values listed are correct, because lspci -vv lists similar values with the same labels (prefetchable, etc.) for my gfx card, so I think those refer to something else.

  • @muru I don't know, to tell you the truth. lspci -vv shows me 256M which is the same as shown in hardinfo and the Nvidia page.

  • Coincidence? Because I checked the output again, and I see it's the exact same values (16, non-prefetchable, 256 and 32, prefetchable). And for my integrated Intel GPU (on a Haswell i5) are 4M, non-prefetchable and 256 prefetchable. Is 256 some magic number? O.o

  • @muru well, it's 2^8 :) But yes, I don't really know what those numbers are. I think the best bet is to find out the card's model and then search the interwebs.
