I am almost certain my Debian 8 computer is just detecting one video card. The computer has two video cards, specifically an Intel HD Graphics 520 (integrated) and NVIDIA GeForce 940-mx (2GB).
I think only one is being detected since when I use the command
lspci -k | grep -A 2 -i "VGA" it returns
00:02.0 VGA compatible controller: Intel Corporation Device 1916 (rev 07) Subsystem: Hewlett-Packard Company Device 820a 00:04.0 Signal processing controller: Intel Corporation Device 1903 (rev 08)
and the command
lspci|grep VGA returns
00:02.0 VGA compatible controller: Intel Corporation Device 1916 (rev 07)
When I ran the above codes the NVIDIA drivers were already supposedly installed, had download them directly from their page and installed them, since the package
nvidia-detect didn't detect any video card in my computer.
Is my NVIDIA card really not being detected? how can I fix this?
