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?


# free -m
             total       used       free     shared    buffers     cached
Mem:          5920       4318       1602          0        113       2465
-/+ buffers/cache:       1740       4180
Swap:         7998          0       7998
