nvidia-detect - a utility to detect NVIDIA graphics cards

nvidia-detect is a utility to detect NVIDIA graphics cards. The utility will probe the PCI bus for NVIDIA devices and search for matching devices against a list of supported device_ids. nvidia-detect will make a recommendation for the correct driver to use based on any matches found. For example:

$ nvidia-detect
kmod-nvidia

Because nvidia-detect outputs the package name on RHEL based systems, it may be used in the following way to install the correct NVIDIA driver for your system:

yum install $(nvidia-detect)


More verbose output is availabe using the verbose (-v) switch, for example:

$ nvidia-detect -v
Probing for supported NVIDIA devices...
10de:0fc1 NVIDIA Corporation GK107 GeForce GT 640
This device requires the current 346.59 NVIDIA driver kmod-nvidia

$ nvidia-detect -v
Probing for supported NVIDIA devices...
10de:0ca3 NVIDIA Corporation GT215 GeForce GT 240
This device requires the legacy 340.xx NVIDIA driver kmod-nvidia-340xx

$ nvidia-detect -v
Probing for supported NVIDIA devices...
10de:0392 NVIDIA Corporation G73 GeForce 7600 GS
This device requires the legacy 304.xx NVIDIA driver kmod-nvidia-304xx


nvidia-detect will also check compatibility between the detected devices recommended driver and the current Xorg Server. The Xorg compatibility tests are always performed and compatibility information is displayed if run with the --xorg (-x) command line argument:

$ nvidia-detect --xorg
Probing for supported NVIDIA devices...
10de:0ca3 NVIDIA Corporation GT215 GeForce GT 240
This device requires the legacy 340.xx NVIDIA driver kmod-nvidia-340xx

Checking ABI compatibility with Xorg Server...
Xorg Video Driver ABI detected: 13
ABI compatibility check passed


nvidia-detect may be run from within a script and will return the following codes:

0: No supported devices found
1: Device supported by the current NVIDIA kmod-nvidia driver
2: Device supported by the NVIDIA legacy kmod-nvidia-96xx driver
3: Device supported by the NVIDIA legacy kmod-nvidia-173xx driver
4: Device supported by the NVIDIA legacy kmod-nvidia-304xx driver
5: Device supported by the NVIDIA legacy kmod-nvidia-340xx driver
