I am on Debian Jessie. I just wanted to install Nvidia drivers. But I found nvidia-detect
does not detect my dedicated chip. Although it is listed in lshw
.
lshw -c video
before any installation
# lshw -c video

Notice, the Nvidia is not listed under VGA.
So, the HW is detected.
But I installed Nvidia drivers according to this http://linuxconfig.org/nvidia-geforce-driver-installation-on-debian-jessie-linux-8-64bit and rebooted (into console) and ran nvidia-detect
AND IT SAYS
nvidia-detect
# nvidia-detect
No NVIDIA GPU detected.
I am unable to startx
, it ended up with an error. In the log I saw No screens detected or similar.
So, what is wrong? Is the dedicated chip dead?

. dunno about other distros. – cas Oct 28 '15 at 07:52nvidia-settings
can detect and switch, so you neednvidia-settings
as well asnvidia-driver
