Subject: [gentoo-user] black screen on boot when udevevents are processed
Date: Tue, 01 Sep 2015 20:23:43 +0200	[thread overview]
Message-ID: <878u8qov68.fsf@heimdali.yagibdah.de> (raw)

Hi,

I'm getting a black screen during booting, with the last message I can
see being that udevevents are being processed.

This happens with an NVIDIA GTX770 connected to a 4k display via a
display port cable, and only when the monitor is configured to use
display port 1.2 rather than 1.1.  With 1.1, I can get only 30Hz refresh
rate, so I want to use 1.2, which should allow 60.

Installed are nvidia-drivers 343.36.

Do I need a very special display port cable for this, or what might the
issue?  Both the graphics card and the monitor should be able to do the
full resolution at 60Hz just fine.

Is the nvidia module loaded just at the point when the message about
processing udevevents is shown?  I suspect that the display goes black
when the module is loaded.

When the screen goes black, I can still log in, blindly, after booting
and do a shutdown or reboot, so apparently everything is working except
only having a black screen.
