I think it would be a very useful functionality — since right now for my reports [and with my specific OS/hardware configuration] it detects only the unused internal (i.e, system-wide) card instead of a dedicated one (used for gaming) making other users unaware of card-specific issues.
Right now it detects:
GPU: Intel Mesa Intel UHD 620 (KBL GT2)
GPU DRIVER: 4.6 Mesa 20.0.6
That additional actual card is present in all of 'graphics-details' -> 'x11/vulkan' sections of 'System Information' report from Steam.
My username is the same as here (thaewrapt), so you should see that info data yourself (I guess). Feel free to ask for any additional info, if needed, and thanks for the awesome work!
