> curious to know why we have 2 sets of nvidia drives - 525, 535?

If you go to https://launchpad.net/~launchpad/+archive/ubuntu/buildd-gpu you'll see these drivers under a PPA owned by Launchpad. The 525 was used by the bos01 arm64 and amd64 +gpu builders, but when we moved the amd64-gpu builders to bos03, we had to upgrade that to 535 for compatibility issues. The g-s-s unit that generates the images used by builders was erroring out, so it never created new images as it should. It took some investigation, but we finally managed to trace it down to the driver, and upgraded it.

I'm guessing that we will need to use the 535 driver here too, but let's try it out and see if we see the same issues before making that change
