Bug ID: 92274 Summary: nouveau black screen and errors with two monitors attached Product: xorg Version: unspecified Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: Driver/nouveau Assignee: nouveau@lists.freedesktop.org Reporter: joseph-thom...@gmx.de QA Contact: xorg-t...@lists.x.org 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. lspci | grep VGA 01:00.0 VGA compatible controller: NVIDIA Corporation GK104 [GeForce GTX 770] (rev a1) kernel version: x86-64 4.0.5-linux-gentoo nouveau version: x11-drivers/xf86-video-nouveau-1.0.11 libdrm version: x11-libs/libdrm-2.4.59 mesa version: media-libs/mesa-10.3.7-r1 X server: x11-base/xorg-server-1.16.4 -- You are receiving this mail because: You are the assignee for the bug.
