Hi:

In my /boot/grub/gfxblacklist.txt file there is a list of 4 devices from 3 vendors:

v15add0710.*
v15add0405.*
v80eedbeef.*
v1002d6738.*

How would I identify the vendors (15ad, 80ee, 1002) and the devices listed?

And how would I determine why they are blacklisted in the first place?

I suspect this is related to the fact that I have both integrated graphics (Radeon Vega) as well as an NVidia Graphics card installed. Things are working just fine, but I would like to understand what's going on.

Thanks in advance for any information ...

In the 1990s & early 2000s, there was some really crappy vendors. SiS did a video card that showed nothing on any graphical boot, because the set of mopdes that graphical setups relied upon were not there. Via did a chipset that conflicted with a Creative Soundblaster; they tweaked settings, but that introduced other faults. Sales sagged in both companies, and they were bought over (probably for the devs).
Having a blacklist doesn't make sense to me. I'd leave it alone and ignore it. The parts are probably cheap tech from the ancient past anyhow.

Thanks for the response.

I certainly agree though, on the other hand, there were great cards in the mid-1980s that I really liked - spent hours designing and adding new font designs into my Hercules RamFont Graphics card (on my first-ever XT machine if I recall correctly).

Still, if anyone knows where to locate the vendor definitions for these codes, I'm still curious ...

80ee VirtualBox
15ad VMware

v1002d6738.* AMD Radeon HD 6870

I have no idea why they would be blacklisted.

Thanks much for the link Michael.
Have a great day.
