Using Ubuntu 15.04 on a desktop that has onboard Intel graphics. Recently installed add-in card with Nvidia GeForce GT-730.
I'm unacquainted with Nvidia drivers and wasn't aware of the complexities... After considerable trouble in trying to install nvidia proprietary drivers from the Nvidia web site, and losing my graphics capabilities in the process, I realized that isn't the right thing to do.
So I switched to the apt package in http://ppa.launchpad.net/graphics-drivers/ppa/ubuntu. Installation of the most recent driver pacakge (
sudo apt-get install nvidia-358) runs successfully and does not report any errors. However, after a reboot I still don't get the nvidia driver - it seems that the nouveau driver is still being used.
I have also tried earlier packages, the results are the same.
Here are some technical details...
Xorg.0.log contains the follwing lines which suggest an error:
[ 27.573] (EE) [drm] KMS not enabled [ 27.573] (EE) No devices detected. [ 27.573] (==) Matched nvidia as autoconfigured driver 0 [ 27.573] (==) Matched nouveau as autoconfigured driver 1 [ 27.573] (==) Matched modesetting as autoconfigured driver 2 [ 27.573] (==) Matched fbdev as autoconfigured driver 3 [ 27.573] (==) Matched vesa as autoconfigured driver 4 [ 27.573] (==) Assigned the driver to the xf86ConfigLayout [ 27.573] (II) LoadModule: "nvidia" [ 27.573] (WW) Warning, couldn't open module nvidia [ 27.573] (II) UnloadModule: "nvidia" [ 27.573] (II) Unloading nvidia [ 27.573] (EE) Failed to load module "nvidia" (module does not exist, 0) [ 27.573] (II) LoadModule: "nouveau" [ 27.573] (II) Loading /usr/lib/xorg/modules/drivers/nouveau_drv.so [ 27.573] (II) Module nouveau: vendor="X.Org Foundation" [ 27.573] compiled for 1.17.1, module version = 1.0.11 [ 27.573] Module class: X.Org Video Driver [ 27.573] ABI class: X.Org Video Driver, version 19.0
I have /etc/modprobe.d/nvidia-358_hybrid.conf which contains the following
# This file was installed by nvidia-358 # Do not edit this file manually blacklist nouveau blacklist lbm-nouveau alias nouveau off alias lbm-nouveau off
lspci -v | grep VGA outputs

glxinfo | grep -i vendor outputs

Any help would be greatly appreciated! let me know if more details are needed.
Edit: output of
