Graphics card memory usage in linux

问题:

What tools are available to monitor graphics card memory usage in linux?

回答1:

If you just need to know it for 3D graphics development purposes, you may want to look into something like gDEBugger or, if you only care about NVIDIA cards, you can try NVIDIA PerfHUD. I have not used them myself, but I would expect them to track such information.

NVIDIA PerfKit has a linux version which allows real-time monitoring of various graphics card properties, including graphics card memory usage. Obviously, this only works for NVIDIA graphics cards, and it also requires the use of a special instrumented driver.
