[Bug 2105377] Re: Plymouth doesn't always show splash screen if DRM drivers are installed in initrd

I did the second test (tbh, I was expecting to be busier today), and using `plymouth.use-simpledrm` option set in the GRUB didn't fix the problem. The initrd had the nvidia drivers, but my test was to check if even with the drivers Plymouth would respect and use simpledrm instead, which didn't.
Do you want logs for this experiment? I disabled `plymouth:debug` for now but I can enable again and provide you with the logs to check why isn't using simpledrm, or if it is, what is going wrong.

Bug description:
  I just updated to plymouth 24.004.60-2ubuntu6 but even the splash screen is enabled, it doesn't show, just text during boot.
  I'm using driver 570.133.07-0ubuntu2. When I was using versiong 570.86.16-0ubuntu4 the splash screen worked as should.

  This bug is a spin off of https://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/2103533, where Daniel asked to create a new bug report about it.
