Process 2082 - Xorg Summary The process Xorg (with pid 2082) is using approximately 73.3 MB of memory. It is using 62.3 MB privately, and a further 32.6 MB that is, or could be, shared with other programs. Dividing up the shared memory between all the processes sharing that memory we get a reduced shared memory usage of 11.1 MB. Adding that to the private usage, we get the above mentioned total memory footprint of 73.3 MB. 3.1 MB is swapped out to disk, probably due to a low amount of available memory left. Library Usage The memory usage of a process is found by adding up the memory usage of each of its libraries, plus the process's own heap, stack and any other mappings.
