I have dabbled in running a Debian server before, but this is my first time using its graphical interface for my main pc. I have been trying to install the nvidia proprietary drivers. I have SLI gtx 460s 1GB. I am running Debian "Jessie" (if it turns out my issues are due to me running the testing build, please let me know).
So far, I have tried following the exact directions on the Debian wiki.
Upon reboot, my primary monitor remains completely blank once the desktop environment launches (I never even see the login screen), though it is still receiving some sort of video signal because the monitor doesn't complain about no signal. This contrasts my secondary monitor which is given no signal whatsoever. Oddly, when I hook up my monitor via HDMI to my motherboard's integrated graphics, I see a black screen with a cursor blinking at the top left corner. I am able to alt+ctrl+F1 to login to the terminal, purge my system of nvidia packages, delete the xorg config file, and reboot; this returns my system to a usable state using nouveau, dual monitors and everything.
I have tried slightly different methods such as installing the 'nvidia-driver' metapackage. Still, I get the same result.
Digging through the Xorg log, I found this segment:
[ 7.605] (II) LoadModule: "glx" [ 7.605] (II) Loading /usr/lib/xorg/modules/linux/libglx.so [ 7.642] (II) Module glx: vendor="NVIDIA Corporation" [ 7.642] compiled for 4.0.2, module version = 1.0.0 [ 7.642] Module class: X.Org Server Extension [ 7.642] (II) NVIDIA GLX Module 331.67 Fri Apr 4 11:43:47 PDT 2014 [ 7.642] Loading extension GLX [ 7.642] (II) LoadModule: "nvidia" [ 7.642] (II) Loading /usr/lib/xorg/modules/drivers/nvidia_drv.so [ 7.649] (II) Module nvidia: vendor="NVIDIA Corporation" [ 7.649] compiled for 4.0.2, module version = 1.0.0 [ 7.649] Module class: X.Org Video Driver [ 7.650] (II) NVIDIA dlloader X Driver 331.67 Fri Apr 4 11:24:40 PDT 2014 [ 7.650] (II) NVIDIA Unified Driver for all Supported NVIDIA GPUs [ 7.650] (++) using VT number 7
Any help would be greatly appreciated. I'll gladly provide any more information that's required. Thanks.
