Subject:   vt(4) gibberish characters in 11.0 with nvidia
Message-ID:  <a01fa902424d7acaea71d66aae4e1cbe@ijs.si>

I have recently upgraded two hosts with identical nvidia boards (GeForce 
GT 730,
fresh driver nvidia-driver-375.26 from ports), one has been following 
11-STABLE
every now and then, the other was on 10.3. So they are now at 
11.0-RELEASE-p7
or on a recent 11-STABLE respectively.

The problem now showing on both hosts is that a virtual terminal console 
driver
(vt(4), no special settings) now shows gibberish character-cells in an
approx 90x24 raster. Character cells are of varying colors, some 
textured,
so it looks as if the font loaded was just random junk.

The boot screen sequence looks fine up to the moment when the X starts.
The X11 screen (with KDE) is fine too. It's just the ttyv0-ttyv7 
consoles
which are broken.

Solved my immediate problem by adding hw.vga.textmode=1 to 
/boot/loader.conf,
so that ttyv consoles now look fine (in fact much nicer, as the vt fonts 
are
pretty squashed and ugly to my eyes).

What puzzles me is what has changed recently, as both hosts were happily
using vt consoles in graphical mode until the upgrade.

(btw, I do have nvidia-modeset.ko and nvidia.ko loaded)
