Hello,
Since I've updated to F13 I keep getting blank screens at "cold" boot
with this card:
00:05.0 VGA compatible controller: nVidia Corporation C51PV [GeForce
6150] (rev a2)
When I say "cold" boot I mean the first couple of times I turn on my
computer in the morning. After a couple of reboots I get plymouth to
show up, and then X11. This never happened with F12.
After comparing the logs (--- bad, +++ good), I found these:
(...)

Although this may seem like a hardware quirk (it may be, partially),
the fact is that I don't have a TV output, only VGA and DVI. So I
guess the driver shouldn't be looking for load on an nonexistent
output. This other log line may be relevant (or not):
Apr 13 08:35:30 localhost kernel: type=1400 audit(1271144119.830:4):
avc: denied { mmap_zero } for pid=462 comm="vbetool"
scontext=system_u:system_r:vbetool_t:s0-s0:c0.c1023
tcontext=system_u:system_r:vbetool_t:s0-s0:c0.c1023 tclass=memprotect
On the other hand, both CRTC's are using output B. I'm not that
familiar with the hardware, and this may be completely wrong, but I
assume an output can only be used by a single CRTC.
Cheers,
Renato
