A utility for collecting internal GPU state, nvidia-debugdump, is included with the NVIDIA Linux graphics driver. After installing the driver, you can run this utility by running:
in a terminal window.
Detailed help information is available via the --help command line option, or when no parameters are supplied.
In most cases, this utility is invoked by the nvidia-bug-report.sh (/usr/bin/nvidia-bug-report.sh) script. In rare cases, typically when directed by an NVIDIA technical support representative, nvidia-debugdump may also be invoked as a stand-alone diagnostics program. The "dump" output of nvidia-debugdump is a binary blob that requires internal NVIDIA engineering tools in order to be interpreted.
