Have a new secondhand PC, running Linux Mint 17.1 Cinnamon 64 Bit, Linux Kernel: 3.13.0-37-generic. System info recognises two VGA cards - onboard and the GTX 770.
However, when I query
lscpi -vnn | grep VGA -A 12
The response I get is:
01:00.0 VGA compatible controller : NVIDIA Corporation GK104 [GeForce GTX 770] [10de:1184] (rev a1) (prog-if 00 [VGA controller]) Subsystem: ASUSTeK Computer Inc. Device [1043:8465] Flags: bus master, fast devsel, latency 0, IRQ 50 Memory at da000000 (32-bit, non-prefetchable) [size=16M] Memory at d0000000 (64-bit, prefetchable) [size=128M] Memory at d8000000 (64-bit, prefetchable) [size=32M] I/O ports at e000 [size=128] [virtual] Expansion ROM at db000000 [disabled] [size=512K] Capabilities: <access denied> Kernel driver in use: nvidia
However this graphics card is supposed to have 2GB GDDR5 as far as I'm aware.
