What is the command to learn video card drivers via windbg?

181951 · Aug 27, 2023

I've been searching but I can't find this command anywhere. I'm sure there is such a command.

What did you mean by learn? Get the details of the graphics card(s)?

x BlueRobot · Aug 27, 2023

The lmnst command will list all the drivers at the time of the crash and lmvm will give you some basic details of a given driver.

I know the lmnst command, but what I want to look for is a command that shows what version the graphics card is, like the command that shows the bios version (!sysinfo machineid)

Do you want the graphics card driver version or the physical details about the graphics card? You can't get the latter information using the standard WinDbg commands as far as I know, unless !sysinfo smbios -devices does.

I just want to know about the graphics card version. I won't go into physical details.

I would recommend that you use lmvm or !lmi then, however, there is no guarantee that the driver version will be avaliable.

I will try, by the way, sorry I forgot to thank you. Thank you for your help.

Video card info like from DirectX?
Win+R type dxdiag hit enter
You'll get this

I don't want to look at the version of my graphics card, I want to look at it when I read the BSoD files. You know, to find out other people's graphics card versions.

You must have the symbols of the given driver in the form of pdb files. I'm not sure if Intel provides these pdb's for their graphics card drivers, you'll have to google the answer to that question

I thought about that, but I wondered if there was a more practical way.

the debugger must have information about the video card driver commands from somewhere, and these are provided in the pdb files

In the file collection app look for the MSINFO32 file The video card info is under Components/Display.

The title of this thread is confusing. It talks about discovering (learning) the graphics (video) card driver details, information which should be available in a minidump or kernel dump. Yet it seems the OP wants to be able to discover the graphics card make and model, which (AFAIK) is not available in either a mindump nor a kernel dump - because the kernel doesn't care what graphics card hardware is installed, it 'sees' it only through the drivers.

That's exactly what I was looking for.

Great. As you saw, the Windbg command is lmDvm followed by the module name with no prefix.

Rich (BB code):

1: kd> lmDvmigdkmdn64

Any other questions? Please feel free to post.

Regards. . .

jcgriff2

p.s. Please keep in mind that I knew the selected module is a video driver written by Intel as I've seen it or a variation of it for well over a decade now.

Thank you @jcgriff2 ! I asked a different question under a new thread to avoid confusion. You can take a look when you can.
