echo 3 > /proc/sys/vm/drop_caches
cleared all of the memory. Thank you! See output below (ran after exiting X).
I didn't try unloading the gpu stack. I can try it if you like.
I also saved /proc/slabinfo before and after I dropped the caches. If I'm
interpreting the file correctly, I only notice large drops in ext4 filesystem
stuff. Is there a way to tell which slabs are considered buffers or cache?
