[This is a very incomplete report. Sorry. I wanted to get this out
before I go to bed. More when I have time.]
I have a Seiki "4k" monitor that I'm using on my Fedora 20 system. I'm
using the nvidia proprietary driver with a Geforce GTX 650 video card. It
has been working well for a while.
I don't remember whether it can work with nouveau. Before I installed
this monitor, I'd switch to the proprietary driver whenever I got annoyed
with crashes in the nouveau driver. Once I switch, it takes a new Fedora
release for me to bother trying nouveau again.
After updates from the last week or so, when I boot, I no longer see
anything on the screen.
It looks like the backlight is on.
The monitor tells me that it detects the 3840x2160 @ 30Hz signal, but
I don't see it.
I can switch to a text console. In fact, that's how I'm composing this
message. And I can switch back.
I can log in blind on the X display (as long as I guess right about
where I am in the invisible dialogue).
I can grab Xorg.0.log -- X is running. Nothing jumps out at me as
wrong.
From the text console, I can run xrandr and all appears to be as I
think that it should be:
Screen 0: minimum 8 x 8, current 3840 x 2160, maximum 16384 x 16384
DVI-I-0 disconnected (normal left inverted right x axis y axis)
DVI-I-1 disconnected (normal left inverted right x axis y axis)
HDMI-0 disconnected (normal left inverted right x axis y axis)
DVI-D-0 connected primary 3840x2160+0+0 (normal left inverted right x axis y
axis) 854mm x 481mm
3840x2160 30.00*+ 29.97 25.00 23.98
1920x1080 59.94 50.00 23.97 60.05 60.00 50.04
1440x900 59.89
1280x960 60.00
1280x720 59.94 50.00
1024x768 75.03 70.07 60.00
800x600 75.00 72.19 60.32
720x576 50.00 50.08
720x480 59.94 60.05
640x480 75.00 72.81 59.94
I've tried to choose a more mainstream mode with xrandr but
have failed.
I've tried to blacklist the nvidia module but have failed. I tried to
use this on the kernel line in /boot/efi/EFI/fedora/grub.cfg:
rd.driver.blacklist=nvidia
(from googling) but the nvidia module still gets loaded and Xorg uses
it. Is there a quick and dirty way of suppressing the nvidia drive
without removing it?
