<pre>Hello,
I switched from the proprietary nvidia-drivers to nouveau under Gentoo.
I use a Dual-Monitor Setup: one is connected to the DVI-I and the other one to
the HDMI output of my Nvidia GTX 770.
Under my Manjaro installation I use the proprietary driver and everything
works;
under Gentoo everything was fine with the nvidia-drivers, too.
Now I can boot without errors into Gentoo when only one of the monitors is
connected, no matter which one.
However, when both monitors are attached to the graphics card,
I cannot access a tty or my graphical login manger:
the screens turn off showing "no input signal".
Me not being able to access my Gentoo installation by booting into it when the
error happens,
I chrooted into it and used cat /var/log/dmesg.
I know that this is not what the nouveau reporting guide suggests for obtaining
a kernel log,
but if I run dmesg from my chrooted environment I obviously get the kernel log
of my Manjaro boot.
If there is another better way for obtaining the kernel log, please let me
know.
VBIOS is following in a few minutes.
If there is anything else missing, let me know.
