  *   Odds are, if you start from stage3, you will get the same problem again unless you do something different.

  *   When I first stated using Gentoo, I didn't realize that one can restart a install pretty much anywhere in the install.

  *   Starting over doesn't get you anything different if you repeat the same steps.



Just to update: I tried all the hints received here with no luck. Since others on this list managed to get uefifb working with the NVIDIA driver I believe the problem could be my mobo/UEFI FW/GPU combination. I found some rather old posts ([1], [2]) supporting this hypothesis. For the moment I switched to nouveau.



Thanks again to all,
