Setting "Version:" to CURRENT, because I'm still facing this bug with
FreeBSD-14-CURRENT #0 main-n261544-cee09bda03c8: Thu Mar 16 08:11:20 UTC 2023.
Actually, I got the problem reported in
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=201461#c19 : a garbled
instead of a blank screen when switching to console (vt), and as reported by
Andreas Bock, setting "hw.vga.textmode=1" in /boot/loader.conf fixed it.
Notes:
- the card is GP104BM [GeForce GTX 1080 Mobile]
- using nvidia-driver-515.86.01_1
- no external screen but the one of the laptop
- amd64 legacy installation
- `nvidia-debugdump -D' reports:
